嘉兴专业定制网站制作企业网站优化推广方法

背景：由于工作需要，当用户在登录时自动触发定时任务。而不需要我们手动到调度中心管理页面去创建任务。
工程介绍：分为两个项目，第一个是调度中心的项目（xxl-job-admin）。第二个是我们自己的项目（myProject）。
步骤如下：

调度中心操作步骤

1.下载xxl-job的源码

点击进入xxl-job项目官网地址
源码下载地址-github
源码下载地址-gitee

1.1、gitee为例，下载2.4.0版本。

1.2、下载代码压缩包

1.3、下载完成，解压压缩包目录展示

1.4、数据库建表，打开doc文件夹，里面有sql文件。到数据库执行就可以创建xxl-job项目所需要的表了。

1.5、打开xxl-job-admin项目（我这里使用的是idea工具）

展开目录如下：

1.6、更新配置（主要两个配置：1.端口默认8080（也可以自定义）2.数据库配置））。报红地方不影响代码运行，可以不用管。

1.7、启动项目访问调度中心，访问地址：http://localhost:8080/xxl-job-admin，默认用户名：admin，默认密码：123456

a.启动日志：

b.登录页面：

c.登录进入首页

进入到以上页面就说明调度中心启动没有问题了，接下来就是改造调度中心为我们所用。

1.8、改造项目

1.8.0、任务组控制器添加新接口用于查找执行器（执行器的意思是，执行任务时用哪个执行器执行，必须要指定）。

a.进入JobGroupController，添加以下代码

代码如下：

	@RequestMapping("/loadByAppName")@ResponseBody@PermissionLimit(limit = false)public ReturnT<XxlJobGroup> loadByAppName(String param) {LoadByAppNameParam loadByAppNameParam = GsonTool.fromJson(param, LoadByAppNameParam.class);String appName = loadByAppNameParam.getAppName();XxlJobGroup jobGroup = xxlJobGroupDao.loadByAppName(appName);try {if (null != jobGroup) {return new ReturnT<XxlJobGroup>(jobGroup);} else {return new ReturnT<XxlJobGroup>(ReturnT.FAIL_CODE, null);}} catch (Exception e) {e.printStackTrace();}return null;}

注：@PermissionLimit(limit = false)注解的含义是跳过登录验证

b.进入XxlJobGroupDao文件添加如下代码

代码如下：

XxlJobGroup loadByAppName(@Param("name") String name);

c.进入XxlJobGroupMapper.xml文件添加如下代码

代码如下：

<select id="loadByAppName" parameterType="java.lang.String" resultMap="XxlJobGroup">SELECT<include refid="Base_Column_List"/>FROM xxl_job_group AS tWHERE t.app_name = #{name}</select>

d.LoadByAppNameParam.java文件是我自定义文件，用来接受appName参数的，后面会讲到。

代码如下：

public class LoadByAppNameParam {private String appName;public String getAppName() {return appName;}public void setAppName(String appName) {this.appName = appName;}}

e.测试，我在调度管理中创建了一个默认执行器，用postman调用接口测试，查看返回数据。注意：后面我还是用xxl-job自带的执行器来演示

我设置的本地ip地址，不填的话默认是当前主机的ip

postman测试接口，查找名为“xxl-job-executor-sample”的执行器。

1.8.1、在JobInfoController.java中添加两个接口

代码如下：

@RequestMapping("/addJob")@ResponseBody@PermissionLimit(limit = false)public ReturnT<String> addJob(String param) {System.out.println(param);XxlJobInfo xxlJobInfo = GsonTool.fromJson(param, XxlJobInfo.class);return xxlJobService.add(xxlJobInfo);}@RequestMapping("/removeJob")@ResponseBody@PermissionLimit(limit = false)public ReturnT<String> removeJob(String id) {return xxlJobService.remove(Integer.parseInt(id));}

这两个接口后面在代码里测试这里就不再演示了。

我们自己项目的操作步骤

1.创建SpringBoot工程（SpringBoot版本2.5.6，jdk版本为1.8，xxl-job-core依赖为2.4.0，lombok插件有使用到，hutool工具包5.5.0，阿里巴巴fastjson）

pom文件如下：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.5.6</version><relativePath/> <!-- lookup parent from repository --></parent><groupId>com.abliner</groupId><artifactId>myProject</artifactId><version>0.0.1-SNAPSHOT</version><name>myProject</name><description>myProject</description><properties><java.version>8</java.version></properties><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope></dependency><!-- xxl-job-core依赖 --><!-- https://mvnrepository.com/artifact/com.xuxueli/xxl-job-core --><dependency><groupId>com.xuxueli</groupId><artifactId>xxl-job-core</artifactId><version>2.3.0</version></dependency><!-- lombok --><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId><optional>true</optional></dependency><!-- hutool工具依赖 --><dependency><groupId>cn.hutool</groupId><artifactId>hutool-json</artifactId><version>5.5.0</version></dependency><!-- JSON转换工具 --><dependency><groupId>com.alibaba</groupId><artifactId>fastjson</artifactId><version>1.2.11</version></dependency></dependencies><build><plugins><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId></plugin></plugins></build></project>

1.0、配置文件application.yml（配置文件默认是application.properties，我喜欢另一种风格所以改成了application.yml。指定启动端口为：8081）

代码如下：

server:port: 8081# Xxl-Job分布式定时任务调度中心
xxl:job:### 执行器通讯TOKEN [选填]：非空时启用；accessToken: default_tokenadmin:### 调度中心部署根地址 [选填]：如调度中心集群部署存在多个地址则用逗号分隔。执行器将会使用该地址进行"执行器心跳注册"和"任务结果回调"；为空则关闭自动注册；addresses: http://127.0.0.1:8080/xxl-job-adminexecutor:### 执行器注册 [选填]：优先使用该配置作为注册地址，为空时使用内嵌服务 ”IP:PORT“ 作为注册地址。从而更灵活的支持容器类型执行器动态IP和动态映射端口问题。address:### 执行器AppName [选填]：执行器心跳注册分组依据；为空则关闭自动注册appname: xxl-job-executor-sample### 执行器IP [选填]：默认为空表示自动获取IP，多网卡时可手动设置指定IP，该IP不会绑定Host仅作为通讯实用；地址信息用于 "执行器注册" 和 "调度中心请求并触发任务"；ip:### 执行器端口号 [选填]：小于等于0则自动获取；默认端口为9999，单机部署多个执行器时，注意要配置不同执行器端口；port: 9999### 执行器运行日志文件存储磁盘路径 [选填] ：需要对该路径拥有读写权限；为空则使用默认路径；logpath: /data/applogs/xxl-job/jobhandler### 执行器日志文件保存天数 [选填] ： 过期日志自动清理, 限制值大于等于3时生效; 否则, 如-1, 关闭自动清理功能；logretentiondays: 30

注意：配置调度中心的地址addresses，我这里用的默认的地址：http://127.0.0.1:8080/xxl-job-admin，如调度中心端口更改，那么我们自己项目里的端口也需要更新。accessToken也是一样，要与调度中心配置保持一致。

1.1、创建配置

1.1.0、创建xxl的配置（没有目录的新建目录，我这里新建了configure和xxl两个目录）

注意：XxlJobConfig.java中忘记加“@Configuration注解”，导致调度中心注册失败，日志提示如下图：

代码演示：

完整代码如下：

package com.abliner.myproject.configure.xxl;import com.xxl.job.core.executor.impl.XxlJobSpringExecutor;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;/*** @author* @date 2023/12/11 14:58* @describe*/@Configuration
public class XxlJobConfig {private Logger logger = LoggerFactory.getLogger(XxlJobConfig.class);@Value("${xxl.job.admin.addresses}")private String adminAddresses;@Value("${xxl.job.accessToken}")private String accessToken;@Value("${xxl.job.executor.appname}")private String appname;@Value("${xxl.job.executor.address}")private String address;@Value("${xxl.job.executor.ip}")private String ip;@Value("${xxl.job.executor.port}")private int port;@Value("${xxl.job.executor.logpath}")private String logPath;@Value("${xxl.job.executor.logretentiondays}")private int logRetentionDays;@Beanpublic XxlJobSpringExecutor xxlJobExecutor() {logger.info(">>>>>>>>>>> xxl-job config init.");XxlJobSpringExecutor xxlJobSpringExecutor = new XxlJobSpringExecutor();xxlJobSpringExecutor.setAdminAddresses(adminAddresses);xxlJobSpringExecutor.setAppname(appname);xxlJobSpringExecutor.setAddress(address);xxlJobSpringExecutor.setIp(ip);xxlJobSpringExecutor.setPort(port);xxlJobSpringExecutor.setAccessToken(accessToken);xxlJobSpringExecutor.setLogPath(logPath);xxlJobSpringExecutor.setLogRetentionDays(logRetentionDays);return xxlJobSpringExecutor;}/*** 针对多网卡、容器内部署等情况，可借助 "spring-cloud-commons" 提供的 "InetUtils" 组件灵活定制注册IP；**      1、引入依赖：*          <dependency>*             <groupId>org.springframework.cloud</groupId>*             <artifactId>spring-cloud-commons</artifactId>*             <version>${version}</version>*         </dependency>**      2、配置文件，或者容器启动变量*          spring.cloud.inetutils.preferred-networks: 'xxx.xxx.xxx.'**      3、获取IP*          String ip_ = inetUtils.findFirstNonLoopbackHostInfo().getIpAddress();*/}

1.1.1、创建RestTemplateConfig.java用于网络请求的配置

完整代码如下：

package com.abliner.myproject.configure;import org.springframework.boot.web.client.RestTemplateBuilder;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.MediaType;
import org.springframework.http.converter.HttpMessageConverter;
import org.springframework.http.converter.json.MappingJackson2HttpMessageConverter;
import org.springframework.web.client.RestTemplate;import java.util.ArrayList;
import java.util.List;/*** @author* @date 2023/12/11 16:19* @describe*/
@Configuration
public class RestTemplateConfig {@Beanpublic RestTemplate restTemplate(RestTemplateBuilder builder) {//先获取到converter列表List<HttpMessageConverter<?>> converters = builder.build().getMessageConverters();for (HttpMessageConverter<?> converter : converters) {//因为我们只想要jsonConverter支持对text/html的解析if (converter instanceof MappingJackson2HttpMessageConverter) {try {//先将原先支持的MediaType列表拷出List<MediaType> mediaTypeList = new ArrayList<>(converter.getSupportedMediaTypes());//加入对text/html的支持mediaTypeList.add(MediaType.TEXT_PLAIN);//将已经加入了text/html的MediaType支持列表设置为其支持的媒体类型列表((MappingJackson2HttpMessageConverter) converter).setSupportedMediaTypes(mediaTypeList);} catch (Exception e) {e.printStackTrace();}}}return builder.build();}
}

1.2、创建XxlJobInfo.java（没有目录的新建目录，我这里新建了model目录。这个对象后面会使用到）

完整代码如下：

package com.abliner.myproject.model;import java.util.Date;/*** @author* @date 2023/12/11 15:14* @describe*/
public class XxlJobInfo {private int id;				// 主键IDprivate int jobGroup;		// 执行器主键IDprivate String jobDesc;private Date addTime;private Date updateTime;private String author;		// 负责人private String alarmEmail;	// 报警邮件private String scheduleType;			// 调度类型private String scheduleConf;			// 调度配置，值含义取决于调度类型private String misfireStrategy;			// 调度过期策略private String executorRouteStrategy;	// 执行器路由策略private String executorHandler;		    // 执行器，任务Handler名称private String executorParam;		    // 执行器，任务参数private String executorBlockStrategy;	// 阻塞处理策略private int executorTimeout;     		// 任务执行超时时间，单位秒private int executorFailRetryCount;		// 失败重试次数private String glueType;		// GLUE类型	#com.xxl.job.core.glue.GlueTypeEnumprivate String glueSource;		// GLUE源代码private String glueRemark;		// GLUE备注private Date glueUpdatetime;	// GLUE更新时间private String childJobId;		// 子任务ID，多个逗号分隔private int triggerStatus;		// 调度状态：0-停止，1-运行private long triggerLastTime;	// 上次调度时间private long triggerNextTime;	// 下次调度时间public int getId() {return id;}public void setId(int id) {this.id = id;}public int getJobGroup() {return jobGroup;}public void setJobGroup(int jobGroup) {this.jobGroup = jobGroup;}public String getJobDesc() {return jobDesc;}public void setJobDesc(String jobDesc) {this.jobDesc = jobDesc;}public Date getAddTime() {return addTime;}public void setAddTime(Date addTime) {this.addTime = addTime;}public Date getUpdateTime() {return updateTime;}public void setUpdateTime(Date updateTime) {this.updateTime = updateTime;}public String getAuthor() {return author;}public void setAuthor(String author) {this.author = author;}public String getAlarmEmail() {return alarmEmail;}public void setAlarmEmail(String alarmEmail) {this.alarmEmail = alarmEmail;}public String getScheduleType() {return scheduleType;}public void setScheduleType(String scheduleType) {this.scheduleType = scheduleType;}public String getScheduleConf() {return scheduleConf;}public void setScheduleConf(String scheduleConf) {this.scheduleConf = scheduleConf;}public String getMisfireStrategy() {return misfireStrategy;}public void setMisfireStrategy(String misfireStrategy) {this.misfireStrategy = misfireStrategy;}public String getExecutorRouteStrategy() {return executorRouteStrategy;}public void setExecutorRouteStrategy(String executorRouteStrategy) {this.executorRouteStrategy = executorRouteStrategy;}public String getExecutorHandler() {return executorHandler;}public void setExecutorHandler(String executorHandler) {this.executorHandler = executorHandler;}public String getExecutorParam() {return executorParam;}public void setExecutorParam(String executorParam) {this.executorParam = executorParam;}public String getExecutorBlockStrategy() {return executorBlockStrategy;}public void setExecutorBlockStrategy(String executorBlockStrategy) {this.executorBlockStrategy = executorBlockStrategy;}public int getExecutorTimeout() {return executorTimeout;}public void setExecutorTimeout(int executorTimeout) {this.executorTimeout = executorTimeout;}public int getExecutorFailRetryCount() {return executorFailRetryCount;}public void setExecutorFailRetryCount(int executorFailRetryCount) {this.executorFailRetryCount = executorFailRetryCount;}public String getGlueType() {return glueType;}public void setGlueType(String glueType) {this.glueType = glueType;}public String getGlueSource() {return glueSource;}public void setGlueSource(String glueSource) {this.glueSource = glueSource;}public String getGlueRemark() {return glueRemark;}public void setGlueRemark(String glueRemark) {this.glueRemark = glueRemark;}public Date getGlueUpdatetime() {return glueUpdatetime;}public void setGlueUpdatetime(Date glueUpdatetime) {this.glueUpdatetime = glueUpdatetime;}public String getChildJobId() {return childJobId;}public void setChildJobId(String childJobId) {this.childJobId = childJobId;}public int getTriggerStatus() {return triggerStatus;}public void setTriggerStatus(int triggerStatus) {this.triggerStatus = triggerStatus;}public long getTriggerLastTime() {return triggerLastTime;}public void setTriggerLastTime(long triggerLastTime) {this.triggerLastTime = triggerLastTime;}public long getTriggerNextTime() {return triggerNextTime;}public void setTriggerNextTime(long triggerNextTime) {this.triggerNextTime = triggerNextTime;}
}

1.3、添加XxlUtil.java工具类，我们要远程调用调度中心需要用到（我这里新建了tool目录）

完整代码如下：

package com.abliner.myproject.tool;import cn.hutool.json.JSONUtil;
import com.abliner.myproject.model.XxlJobInfo;
import com.alibaba.fastjson.JSON;
import com.alibaba.fastjson.JSONObject;
import lombok.RequiredArgsConstructor;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.http.HttpEntity;
import org.springframework.http.HttpHeaders;
import org.springframework.http.MediaType;
import org.springframework.http.ResponseEntity;
import org.springframework.stereotype.Component;
import org.springframework.util.LinkedMultiValueMap;
import org.springframework.util.MultiValueMap;
import org.springframework.web.client.RestTemplate;import java.util.HashMap;
import java.util.Map;/*** @author* @date 2023/12/11 15:22* @describe*/
@Component
@RequiredArgsConstructor
public class XxlUtil {@Value("${xxl.job.admin.addresses}")private String xxlJobAdminAddress;private final RestTemplate restTemplate;// xxl-job各种请求地址private static final String ADD_INFO_URL = "/jobinfo/addJob";private static final String REMOVE_INFO_URL = "/jobinfo/removeJob";private static final String GET_GROUP_ID = "/jobgroup/loadByAppName";/*** 添加任务** @param xxlJobInfo* @param appName* @return*/public String addJob(XxlJobInfo xxlJobInfo, String appName) {//组装参数Map<String, Object> params = new HashMap<>();params.put("appName", appName);String json = JSONUtil.toJsonStr(params);//调用xxl-job接口添加任务String result = doPost(xxlJobAdminAddress + GET_GROUP_ID, json);//获取执行器的idJSONObject jsonObject = JSON.parseObject(result);Map<String, Object> map = (Map<String, Object>) jsonObject.get("content");Integer groupId = (Integer) map.get("id");xxlJobInfo.setJobGroup(groupId);String xxlJobInfoJson = JSONUtil.toJsonStr(xxlJobInfo);//添加这个jobreturn doPost(xxlJobAdminAddress + ADD_INFO_URL, xxlJobInfoJson);}// 删除jobpublic String removeJob(long jobId) {MultiValueMap<String, String> map = new LinkedMultiValueMap<String, String>();map.add("id", String.valueOf(jobId));return doPostWithFormData(xxlJobAdminAddress + REMOVE_INFO_URL, map);}/*** 远程调用** @param url* @param json*/private String doPost(String url, String json) {HttpHeaders headers = new HttpHeaders();headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);MultiValueMap<String, String> map = new LinkedMultiValueMap<String, String>();map.add("param", json);HttpEntity<MultiValueMap<String, String>> entity = new HttpEntity<>(map, headers);ResponseEntity<String> responseEntity = restTemplate.postForEntity(url, entity, String.class);return responseEntity.getBody();}private String doPostWithFormData(String url, MultiValueMap<String, String> map) {HttpHeaders headers = new HttpHeaders();headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);HttpEntity<MultiValueMap<String, String>> entity = new HttpEntity<>(map, headers);ResponseEntity<String> responseEntity = restTemplate.postForEntity(url, entity, String.class);return responseEntity.getBody();}}

1.4、编写XxlService.java（注意新建service和impl目录）

完整代码如下：

package com.abliner.myproject.service.impl;import com.abliner.myproject.model.XxlJobInfo;
import com.abliner.myproject.tool.XxlUtil;
import lombok.RequiredArgsConstructor;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Service;/*** @author* @date 2023/12/11 15:43* @describe*/
@Service
@Slf4j
@RequiredArgsConstructor
public class XxlService {private final XxlUtil xxlUtil;@Value("${xxl.job.executor.appname}")private String appName;public void addJob(XxlJobInfo xxlJobInfo) {xxlUtil.addJob(xxlJobInfo, appName);log.info("任务已添加");}}

1.5、新建时间转换工具类DateUtils.java

完整代码如下：

package com.abliner.myproject.tool;import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;/*** @author* @date 2023/12/11 15:56* @describe*/
public class DateUtils {// 使用 DateTimeFormatter 格式化时间public static final DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy MM dd HH mm ss");/*** 时间转换Cron表达式** @param dateTime* @return Cron表达式* @author*/public static String getCron(LocalDateTime dateTime) {String formattedDateTime = dateTime.format(formatter);String[] dateTimeParts = formattedDateTime.split(" ");String cron = String.format("%s %s %s %s %s ? %s-%s", dateTimeParts[5], dateTimeParts[4], dateTimeParts[3], dateTimeParts[2], dateTimeParts[1], dateTimeParts[0], dateTimeParts[0]);return cron;}}

1.6、模拟登录请求

1.6.0、controlelr层->LoginController.java

完整代码如下：

package com.abliner.myproject.controller;import com.abliner.myproject.service.LoginService;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;import javax.annotation.Resource;/*** @author* @date 2023/12/11 15:40* @describe*/
@RestController
@RequestMapping("server")
public class LoginController {@Resourceprivate LoginService loginService;@GetMapping("/login")public String login(@RequestParam("name") String name,@RequestParam("password") String password) {loginService.login(name, password);return "登录成功";}}

1.6.2、service层->LoginService.java

完整代码如下：

package com.abliner.myproject.service;/*** @author* @date 2023/12/11 15:48* @describe*/
public interface LoginService {/*** 登录** @param name* @param password* */void login(String name,String password);}

1.6.3、service实现层->LoginServiceImpl.java

完整代码如下：

package com.abliner.myproject.service.impl;import com.abliner.myproject.model.XxlJobInfo;
import com.abliner.myproject.service.LoginService;
import com.abliner.myproject.tool.DateUtils;
import org.springframework.stereotype.Service;
import org.springframework.util.StringUtils;import javax.annotation.Resource;
import java.time.LocalDateTime;/*** @author * @date 2023/12/11 15:51* @describe*/
@Service
public class LoginServiceImpl implements LoginService {@Resourceprivate XxlService xxlService;/*** 登录** @param name* @param password*/@Overridepublic void login(String name, String password) {if (!StringUtils.isEmpty(password)) {if ("123456".equals(password)) {// 登录成功// 创建一个1分钟后向用户问好的任务LocalDateTime scheduleTime = LocalDateTime.now().plusMinutes(1L);XxlJobInfo xxlJobInfo = new XxlJobInfo();xxlJobInfo.setJobDesc("定时给用户发送通知");xxlJobInfo.setAuthor("imHJ");xxlJobInfo.setScheduleType("CRON");xxlJobInfo.setScheduleConf(DateUtils.getCron(scheduleTime));xxlJobInfo.setGlueType("BEAN");xxlJobInfo.setExecutorHandler("sayHelloHandler");xxlJobInfo.setExecutorParam(name);xxlJobInfo.setMisfireStrategy("DO_NOTHING");xxlJobInfo.setExecutorRouteStrategy("FIRST");xxlJobInfo.setExecutorBlockStrategy("SERIAL_EXECUTION");xxlJobInfo.setTriggerStatus(1);//将任务提交到xxl-job-adminxxlService.addJob(xxlJobInfo);}}}
}

1.6.4、新建JobHandler.java执行器，用于处理任务（定时任务执行的具体业务）

完整代码如下：

package com.abliner.myproject.handler;import com.abliner.myproject.tool.XxlUtil;
import com.xxl.job.core.context.XxlJobHelper;
import com.xxl.job.core.handler.annotation.XxlJob;
import lombok.extern.slf4j.Slf4j;
import org.springframework.stereotype.Component;/*** @author* @date 2023/12/11 16:05* @describe*/
@Component
@Slf4j
public class JobHandler {private final XxlUtil xxlUtil;public JobHandler(XxlUtil xxlUtil) {this.xxlUtil = xxlUtil;}@XxlJob(value = "sayHelloHandler")public void execute() {String userName = XxlJobHelper.getJobParam();log.info("欢迎您： {}！", userName);// 避免一次性任务，留在界面，这里手动删除处理掉long jobId = XxlJobHelper.getJobId();xxlUtil.removeJob(jobId);}}

以上是全部代码的编写，最后测试，还是用postman来测试。
A.postman展示

B.调度中心展示

C.idea控制台展示

最后整个流程执行完成。
