之前我们使用 XXL-JOB 是使用官方自带的代码模块,我们可以自己将 XXL-JOB 的核心代码整理出来,整合到我们的实际项目中。
比如官网自带的 SpringBoot 项目的 pom.xml 配置,使用的 parent 如图所示,我们在自己的公司里,有自己的 parent 依赖,因此我们需要把核心的依赖提取出来。
我们先创建一个项目:
修改 pom.xml 配置
①我们把 XXL-JOB 的 SpringBoot 除 parent 节点以外的内容拷贝过来。即 dependencyManagement 节点和 build 节点。
②找到 XXL-JOB 的 SpringBoot 最外层的 pom.xml 的 parent,点击进入,把 <properties> 节点的内容拷贝过来。
③最后缺少 xxl-job-core 核心包,如图:
我们可以把它的核心包安装到我们本地 Maven 仓库,也可以写固定。比如我使用的版本号是 2.3.0
完整的 pom.xml 配置如下:
- <?xml version="1.0" encoding="UTF-8"?>

我们的项目结构如图:
配置文件:XxlJobConfig,完全是复制 XXL-JOB 的配置文件,完整代码:
- package com.study.config;
-
- 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;
- import org.springframework.context.annotation.Configuration;
-
- /**
- * xxl-job config
- *
- * @author xuxueli 2017-04-28
- */
- @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;
-
-
- @Bean
- public 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;
- }
-
- }
JobController 代码如下(只是为了验证我们的微服务是否启动成功):
- package com.study.controller;
-
- import org.springframework.web.bind.annotation.RequestMapping;
- import org.springframework.web.bind.annotation.RestController;
-
- /**
- * @author biandan
- * @description
- * @signature 让天下没有难写的代码
- * @create 2021-05-26 下午 5:27
- */
- @RestController
- public class JobController {
-
- @RequestMapping(value = "/index")
- public String test() {
- return "Welcome! 如果看到此信息,说明服务启动成功!";
- }
-
- }
任务类:MyJob,代码如下:
- package com.study.job;
-
- import com.xxl.job.core.context.XxlJobHelper;
- import com.xxl.job.core.handler.annotation.XxlJob;
- import org.springframework.beans.factory.annotation.Value;
- import org.springframework.stereotype.Component;
-
- import java.text.SimpleDateFormat;
- import java.util.Date;
-
- /**
- * @author biandan
- * @description
- * @signature 让天下没有难写的代码
- * @create 2021-05-26 下午 5:33
- */
- @Component
- public class MyJob{
-
- @Value("${xxl.job.executor.port}")
- private int port;
-
- SimpleDateFormat SDF = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
-
- /**
- * 我的个人测试 handler
- *
- * @throws Exception
- */
- @XxlJob("jobStudyHandler")
- public void jobStudyHandler(){
- String param = XxlJobHelper.getJobParam();
- String msg = "执行器端口号:" + port + ",当前时间:" + SDF.format(new Date()) + ",获取到的参数:" + param;
- XxlJobHelper.log(msg);
- System.out.println(msg);
- }
-
- }
说明:获取参数使用 XxlJobHelper.getJobParam() 方法获取。
启动类:StudyJobApplication
- package com.study;
-
- import org.springframework.boot.SpringApplication;
- import org.springframework.boot.autoconfigure.SpringBootApplication;
-
- /**
- * @author biandan
- * @description
- * @signature 让天下没有难写的代码
- * @create 2021-05-26 下午 5:25
- */
- @SpringBootApplication
- public class StudyJobApplication {
-
- public static void main(String[] args) {
- SpringApplication.run(StudyJobApplication.class,args);
- }
-
- }
配置信息 application.properties:
- # web port
- server.port=9001
- # no web
- #spring.main.web-environment=false
-
- # log config
- logging.config=classpath:logback.xml

-
- ### xxl-job, access token
- xxl.job.accessToken=
-
- ### xxl-job executor appname
- # 执行器应用的名字
- # xxl.job.executor.appname=xxl-job-executor-sample
- xxl.job.executor.appname=job-study-appname
- ### xxl-job executor registry-address: default use address to registry , otherwise use ip:port if address is null
- xxl.job.executor.address=
- ### xxl-job executor server-info
- xxl.job.executor.ip=
- xxl.job.executor.port=9090
- ### xxl-job executor log-path
- xxl.job.executor.logpath=/data/applogs/xxl-job/jobhandler
- ### xxl-job executor log-retention-days
- xxl.job.executor.logretentiondays=30
logback.xml 文件:
- <?xml version="1.0" encoding="UTF-8"?>
- <configuration debug="false" scan="true" scanPeriod="1 seconds">
-
- <contextName>logback</contextName>
- <property name="log.path" value="/data/applogs/xxl-job/xxl-job-executor-sample-springboot.log"/>

- </root>
-
- </configuration>
OK,我们启动我们的微服务,访问地址:http://127.0.0.1:9001/index
然后我们启动调度中心微服务,并配置我们的执行器信息、任务信息。
1、启动调度中心微服务
2、配置执行器信息
3、创建任务
4、启动任务,可以看到执行器的微服务不断的打印如下信息:(拿到了参数,我们可以根据一定的规则转成我们想要的格式,比如 JSON 格式、数组格式等)
OK,SpringBoot 整合 XXL-JOB 搞定。我们可以移植到我们的实际项目中。
