一、分布式定时任务

xxl-job是分布式任务调度的平台，可以在图形界面操作，解决分布式的定时任务的重复执行，不能直接修改定时设置等

二、使用步骤

1.pom文件

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.4.2</version>
    </parent>
    <groupId>org.example.test</groupId>
    <artifactId>xxl-job-test</artifactId>
    <version>1.0-SNAPSHOT</version>
    <dependencies>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

        <!-- 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>

2.application.yml

server:
  port: 8093

xxl:
  job:
    admin:
      addresses: http://127.0.0.1:8080/xxl-job-admin #调度中心地址
    accessToken: #执行器通讯token
    executor:
      appname: springboot-xxl-job #执行器名称，执行器心跳注册分组依据，为空时关闭自动注册
      address: #执行器注册地址
      ip: #执行器IP
      port: 9999 #执行器端口号
      logpath: /data/applogs/xxl-job/jobhandler #执行器运行日志文件存储路径
      logretentiondays: 30 #日志文件保存天数

3.configuration配置

package com.test.configure;

import com.xxl.job.core.executor.impl.XxlJobSpringExecutor;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;


@Configuration
public class XXlJobConfig {
    @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}")
    private String logPath;

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


    @Bean
    public XxlJobSpringExecutor xxlJobExecutor() {
        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;
    }
}

4.定时任务逻辑处理

package com.test.jobhandler;


import com.xxl.job.core.context.XxlJobHelper;
import com.xxl.job.core.handler.annotation.XxlJob;
import org.springframework.stereotype.Component;


@Component
public class TestJobHandler {
    @XxlJob("testJobHandler")
    public void testJobHandler() throws Exception {
        XxlJobHelper.log("XXL-JOB, Hello World.");

        for (int i = 0; i < 5; i++) {
            XxlJobHelper.log("beat at:" + i);
            System.out.println(i);
        }
        // default success
    }

}
