1、添加依赖

     <dependency>
         <groupId>com.xuxueli</groupId>
         <artifactId>xxl-job-core</artifactId>
         <version>2.4.0</version>
     </dependency>

2、application.yml 配置

xxl:
  job:
  	accessToken: default_token
    admin:
      addresses: http://{自己部署了调度中心的服务器ip}:{指定端口}/xxl-job-admin
    executor:
      appname: xxl-job-executor-sample
      port: 9998

appname对应在调度中心创建的执行器名称：

3、 新建配置类

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.port}")
    private int port;

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



    @Bean
    public XxlJobSpringExecutor xxlJobExecutor() {
        logger.info(">>>>>>>>>>> xxl-job config init.");
        XxlJobSpringExecutor xxlJobSpringExecutor = new XxlJobSpringExecutor();
        xxlJobSpringExecutor.setAdminAddresses(adminAddresses);
        xxlJobSpringExecutor.setAppname(appname);
        xxlJobSpringExecutor.setAccessToken(accessToken);
        xxlJobSpringExecutor.setPort(port);
        return xxlJobSpringExecutor;
    }


}


}

4、创建任务

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

@Component
public class HelloJob {


    @XxlJob("demoJobHandler")
    public void helloJob(){
        System.out.println("简单任务执行了。。。。");

    }
}

@XxlJob注解里的内容为任务的处理程序JobHandler对应内容：（不要瞎写！！！）

5、将项目打包，在服务器上运行

6、编辑执行器机器地址

ip为网卡ip，通过ifconfig指令查看 eth0
端口为配置文件里设置的执行器端口

7、测试

设置调度周期为每秒执行一次：

成功：
