首先这个是基于docker的所以需要进行docker配置

1、先导入官方提供的SQL到虚拟机中mysql中

在这里插入图片描述

2、创建容器

docker run -e PARAMS="--spring.datasource.url=jdbc:mysql://192.168.211.136:3306/xxl_job?useUnicode=true&characterEncoding=UTF-8&autoReconnect=true&serverTimezone=Asia/Shanghai --spring.datasource.username=root --spring.datasource.password=123456 --spring.datasource.driver-class-name=com.mysql.jdbc.Driver" -p 8080:8080 -v /tmp:/data/applogs --name xxl-job-admin  -d --restart=always xuxueli/xxl-job-admin:2.1.2

3、在你的微服务中添加依赖

<dependency>
    <groupId>com.xuxueli</groupId>
    <artifactId>xxl-job-core</artifactId>
    <version>2.1.2</version>
</dependency>

4、在你的微服务的yml中和spring平级添加如下内容：

xxl:
  job:
    accessToken: ''
    admin:
      addresses: http://192.168.211.136:8080/xxl-job-admin
    executor:
      appname: leadnews-admin # 本服务的名称
      ip: '' # 不写会自动确定
      logretentiondays: 30
      port: -1 # 不写会自动找一个端口

5、在你的微服务中添加配置(和pojo、mapper目录平级)，新建一个config目录，其中存放如下内容：

package com.jjw.admin.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;

@Configuration
public class XxlJobConfig {
    private Logger logger = LoggerFactory.getLogger(XxlJobConfig.class);

    @Value("${xxl.job.admin.addresses}")
    private String adminAddresses;

    @Value("${xxl.job.executor.appname}")
    private String appName;

    @Value("${xxl.job.executor.ip}")
    private String ip;

    @Value("${xxl.job.executor.port}")
    private int port;

    @Value("${xxl.job.accessToken}")
    private String accessToken;

    @Value("${xxl.job.executor.logpath:abc}")
    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.setIp(ip);
        xxlJobSpringExecutor.setPort(port);
        xxlJobSpringExecutor.setAccessToken(accessToken);
        xxlJobSpringExecutor.setLogPath(logPath);
        xxlJobSpringExecutor.setLogRetentionDays(logRetentionDays);

        return xxlJobSpringExecutor;
    }
}

6、在你的微服务中和config目录平级创建task目录，内容为：

package com.jjw.admin.task;

import com.xxl.job.core.biz.model.ReturnT;
import com.xxl.job.core.handler.annotation.XxlJob;
import org.springframework.stereotype.Component;

import java.util.Date;

@Component
public class TestTask {
    @XxlJob(value="teskTask")
    public ReturnT<String> teskTask(String param){
        System.out.println("执行任务======="+new Date());

        //XxlJobLogger.log("XXL-JOB, Hello World.demo1:"+param);
        //System.out.println("参数打印==="+param);
        //
        //System.out.println("now:end:"+new Date());

        return ReturnT.SUCCESS;
    }
}
