XXL-JOB快速集成

1.编写配置文件

XxlJobConfig

package com.lkd.job;

import com.xxl.job.core.executor.impl.XxlJobSpringExecutor;
import lombok.extern.slf4j.Slf4j;
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
@Slf4j
public class XxlJobConfig {


    @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() {
        log.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;
    }

}

application.yml 

xxl:
  job:
    accessToken:
    admin:
      addresses: http://192.168.200.128:8080/xxl-job-admin     #xxl-job安装地址
    executor:
      appname: user-service    #执行器名称
      address:
      ip:
      port: 0          #配置成0自动分配
      logretentiondays: 30

2.配置 XXL-JOB 中任务调度中心

任务管理

3.添加任务类（一般放在job包下）

import com.lkd.common.VMSystem;
import com.lkd.service.UserService;
import com.xxl.job.core.biz.model.ReturnT;
import com.xxl.job.core.handler.annotation.XxlJob;
import com.xxl.job.core.log.XxlJobLogger;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.stereotype.Component;

import java.time.Duration;
import java.time.LocalDate;
import java.time.format.DateTimeFormatter;

/**
 * XxlJob开发示例（Bean模式）
 *
 * 开发步骤：
 * 1、在Spring Bean实例中，开发Job方法，方式格式要求为 "public ReturnT execute(String param)"
 * 2、为Job方法添加注解 "@XxlJob(value="自定义jobhandler名称", init = "JobHandler初始化方法", destroy = "JobHandler销毁方法")"，注解value值对应的是调度中心新建任务的JobHandler属性的值。
 * 3、执行日志：需要通过 "XxlJobLogger.log" 打印执行日志；

@Component
@Slf4j
public class UserJob {

    /**
     * 1、简单任务示例（Bean模式）
     */
    @XxlJob("workCountInitJobHandler")
    public ReturnT demoJobHandler(String param) throws Exception {
        XxlJobLogger.log("XXL-JOB, Hello World.");

        for (int i = 0; i < 5; i++) {
            XxlJobLogger.log("beat at:" + i);
            TimeUnit.SECONDS.sleep(2);
        }
        return ReturnT.SUCCESS;
    }
    
    /**
     * 2、分片广播任务
     */
    @XxlJob("shardingJobHandler")
    public ReturnT shardingJobHandler(String param) throws Exception {

        // 分片参数
        ShardingUtil.ShardingVO shardingVO = ShardingUtil.getShardingVo();
        XxlJobLogger.log("分片参数：当前分片序号 = {}, 总分片数 = {}", shardingVO.getIndex(), shardingVO.getTotal());

        // 业务逻辑
        for (int i = 0; i < shardingVO.getTotal(); i++) {
            if (i == shardingVO.getIndex()) {
                XxlJobLogger.log("第 {} 片, 命中分片开始处理", i);
            } else {
                XxlJobLogger.log("第 {} 片, 忽略", i);
            }
        }

        return ReturnT.SUCCESS;
    }

}
