spring boot 接入xxl-job手册

xxl-job 分布式job调度中心接入手册

项目是spring cloud框架，eureka注册中心，使用许雪里的xxl-job，打算后续将其改造为spring boot工程，接入服务中心。以下是我对其源码接入spring cloud/boot的使用方式，可改良之处尚多，仅给大家提供参考，方便使用。

xxl-job项目地址：

github https://github.com/xuxueli/xxl-job

document http://www.xuxueli.com/xxl-job/

对原项目的介绍此处不再细说，可点开上面的参考文档熟悉
改动后的admin地址：https://github.com/lich1n/my-xxl-job

改动内容：
- 添加了通过业务单号查询job的方法
- 将jobinfo操作的几个接口直接暴露出来了，接我们系统权限验证的我移除了。
- jobinfo表增加业务类型及单号字段

使用方式
将xxl-job-admin打包部署好，自己的业务系统接入job中心启动即可。上面改动过的admin修改mysql连接地址后即可运行，sql脚本为resources下的tables_xxl_job.sql

以下是业务模块的接入过程


spring boot 项目接入步骤


1. 引入依赖
2. yml配置
3. 装配配置类
4. 创建jobhandler执行器
5. 进入xxl-job控制台新增执行器
6. 使用新增的执行器开始任务
7. 在业务模块中操作job的【增、删、改、查、暂停】

1 . 引入依赖

<dependency>
    <groupId>com.xuxueligroupId>
    <artifactId>xxl-job-coreartifactId>
    <version>1.9.1version>
dependency>

2. yml配置

xxl:
  job:
    admin:
      ### xxl-job admin address list, such as "http://address" or "http://address01,http://address02"
      addresses: http://localhost:8080
    ### xxl-job executor address
    executor:
      appname: mktcenter
      ip:
      port: 9888
      ### xxl-job log path
      logpath: /data/applogs/xxl-job/jobhandler
      ### xxl-job log retention days
      logretentiondays: -1
    ### xxl-job, access token
    accessToken:

3. 装配配置类

package com.bizvane.mktcenterserviceimpl.common.job;
import com.xxl.job.core.executor.XxlJobExecutor;
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.ComponentScan;
import org.springframework.context.annotation.Configuration;
@Configuration
@ComponentScan(basePackages = "com.bizvane.mktcenterserviceimpl.service.jobhandler")
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}")
    private String logPath;

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


    @Bean(initMethod = "start", destroyMethod = "destroy")
    public XxlJobExecutor xxlJobExecutor() {
        logger.info(">>>>>>>>>>> xxl-job config init.");
        XxlJobExecutor xxlJobExecutor = new XxlJobExecutor();
        xxlJobExecutor.setAdminAddresses(adminAddresses);
        xxlJobExecutor.setAppName(appName);
        xxlJobExecutor.setIp(ip);
        xxlJobExecutor.setPort(port);
        xxlJobExecutor.setAccessToken(accessToken);
        xxlJobExecutor.setLogPath(logPath);
        xxlJobExecutor.setLogRetentionDays(-1);

        return xxlJobExecutor;
    }
}

4. 创建jobhandler执行器

package com.bizvane.mktcenterserviceimpl.service.jobhandler;

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

@JobHandler(value="activity")
@Component
public class ActivityJobHandler extends IJobHandler {

    @Override
    public ReturnT execute(String param) throws Exception {
        System.out.println("开始执行生日活动");
        return null;
    }
}

5. 进入xxl-job控制台新增执行器

注意appname与yml中配置名字保持一致 !

6. 使用新增的执行器开始任务

JobHandler名字为步骤4中@JobHandler注解value值

保存即可。

7. 在业务模块中操作job的【增、删、改、查、暂停】等

        ResponseEntity response = this.restTemplate.postForEntity(this.getLoadUrl(getJobInfoByBiz), request, String.class, new Object[0]);
        return response;

                Object o = fields[i].get(obj);
                if (o != null) {
                    map.put(varName, Collections.singletonList(o.toString()));
                }

            }
        }

        return map;
    }
}

添加了业务类型及code的实体类

package com.bizvane.utils.jobutils;

import java.util.Date;

public class XxlJobInfo {
    private int id;
    private int jobGroup;
    private String jobCron;
    private String jobDesc;
    private Date addTime;
    private Date updateTime;

    }

    public String getJobDesc() {
        return this.jobDesc;
    }

    public void setJobDesc(String jobDesc) {
        this.jobDesc = jobDesc;
    }

    public Date getAddTime() {
        return this.addTime;
    }

    public void setAddTime(Date addTime) {
        this.addTime = addTime;
    }

    public Date getUpdateTime() {

    }

    public void setUpdateTime(Date updateTime) {

    }

    public String getAlarmEmail() {

    }

    public void setAlarmEmail(String alarmEmail) {
        this.alarmEmail = alarmEmail;
    }

    public String getExecutorRouteStrategy() {
        return this.executorRouteStrategy;
    }

    public void setExecutorRouteStrategy(String executorRouteStrategy) {
        this.executorRouteStrategy = executorRouteStrategy;
    }

    public String getExecutorHandler() {
        return this.executorHandler;
    }

    public void setExecutorHandler(String executorHandler) {
        this.executorHandler = executorHandler;
    }

    public String getExecutorParam() {
        return this.executorParam;
    }

    public void setExecutorParam(String executorParam) {
        this.executorParam = executorParam;
    }

    public String getExecutorBlockStrategy() {
        return this.executorBlockStrategy;
    }

    public void setExecutorBlockStrategy(String executorBlockStrategy) {
        this.executorBlockStrategy = executorBlockStrategy;
    }

    public String getExecutorFailStrategy() {
        return this.executorFailStrategy;
    }

    public void setExecutorFailStrategy(String executorFailStrategy) {
        this.executorFailStrategy = executorFailStrategy;
    }

    public int getExecutorTimeout() {
        return this.executorTimeout;
    }

    public void setExecutorTimeout(int executorTimeout) {
        this.executorTimeout = executorTimeout;
    }

    public String getGlueType() {
        return this.glueType;
    }

    public void setGlueType(String glueType) {
        this.glueType = glueType;
    }

    public String getGlueSource() {
        return this.glueSource;
    }

    public void setGlueSource(String glueSource) {
        this.glueSource = glueSource;
    }

    public String getGlueRemark() {
        return this.glueRemark;
    }

    public void setGlueRemark(String glueRemark) {
        this.glueRemark = glueRemark;
    }

    public Date getGlueUpdatetime() {
        return this.glueUpdatetime;
    }

    public void setGlueUpdatetime(Date glueUpdatetime) {
        this.glueUpdatetime = glueUpdatetime;
    }

    public String getChildJobId() {
        return this.childJobId;
    }

    public void setChildJobId(String childJobId) {
        this.childJobId = childJobId;
    }

    public String getJobStatus() {
        return this.jobStatus;
    }

    public void setJobStatus(String jobStatus) {
        this.jobStatus = jobStatus;
    }

    public String getAppName() {
        return this.appName;
    }

    public void setAppName(String appName) {
        this.appName = appName;
    }

    public Integer getBizType() {
        return this.bizType;
    }

    public void setBizType(Integer bizType) {
        this.bizType = bizType;
    }

    public String getBizCode() {
        return this.bizCode;
    }

    public void setBizCode(String bizCode) {
        this.bizCode = bizCode;
    }
}

再封装一个工具类使用jobclient，下面给出了一个添加job的操作

package com.bizvane.mktcenterserviceimpl.common.utils;

import com.bizvane.mktcenterservice.models.po.MktTaskPOWithBLOBs;
import com.bizvane.mktcenterservice.models.vo.ActivitySmartVO;

import com.bizvane.utils.jobutils.XxlJobInfo;
import com.bizvane.utils.tokens.SysAccountPO;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

import java.util.Date;

/**
 * @author chen.li

 */
@Component
public class JobUtil {
    @Autowired
    private XxlJobConfig xxlJobConfig;

    @Autowired
    private JobClient jobClient;

    /**

     * @param businessType
     */
    public void addJob(Date execuDate,String desc,String param,String author,String jobHandler,int businessType){
        //构建job对象
        XxlJobInfo xxlJobInfo = new XxlJobInfo();
        //设置appName
        xxlJobInfo.setAppName(xxlJobConfig.getAppName());
        //设置路由策略
        xxlJobInfo.setExecutorRouteStrategy(JobEnum.EXECUTOR_ROUTE_STRATEGY_FIRST.getValue());
        //设置job定时器
        xxlJobInfo.setJobCron(DateUtil.getCronExpression(execuDate));
        //设置运行模式
        xxlJobInfo.setGlueType(JobEnum.GLUE_TYPE_BEAN.getValue());
        //设置job处理器
        xxlJobInfo.setExecutorHandler(jobHandler);
        //设置job描述
        xxlJobInfo.setJobDesc(desc);
        //设置执行参数
        xxlJobInfo.setExecutorParam(param);
        //设置阻塞处理策略
        xxlJobInfo.setExecutorBlockStrategy(JobEnum.EXECUTOR_BLOCK_SERIAL_EXECUTION.getValue());
        //设置失败处理策略
        xxlJobInfo.setExecutorFailStrategy(JobEnum.EXECUTOR_FAIL_STRATEGY_NULL.getValue());
        //设置负责人
        xxlJobInfo.setAuthor(author);
        //设置业务类型
        xxlJobInfo.setBizType(businessType);
        //添加job
        jobClient.addJob(xxlJobInfo);
    }

}

至此将job-admin启动起来，自己的业务模块启动起来，就可通过业务操作对job中心的job进行更改，也可以直接在job平台直观操作job控制业务模块的jobhandler的执行。由于restTemplate的loadBalance注解会产生问题，具体问题我没有细查，因此在启动类上需要注释掉此注解，于是我手动在上面jobClient最下方中做了简单的请求负载。以下是启动类代码
