• xxl-job项目定时管理工具


    1.源码下载地址:

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

    2.将源码clone到IDEA中:

         

    3.初始化数据库脚本: /doc/db/tables_xxl_job.sql ;

    4.xxl-job-admin的配置文件application.properties:

    ### web
    ### 1、调度中心项目的端口号以及访问路径
    server.port=8081
    server.servlet.context-path=/xxl-job-admin
    
    ### actuator

    xxl.job.i18n=zh_CN
    
    ## xxl-job, triggerpool max size
    xxl.job.triggerpool.fast.max=200
    xxl.job.triggerpool.slow.max=100
    
    ### xxl-job, log retention days
    xxl.job.logretentiondays=30

    5.部署调度中心   

      该工程是一个springboot项目,我们只需要在IDEA中执行 XxlJobAdminApplication 类即可运行该工程;

    6.在浏览器输入 http://localhost:8080/xxl-job-admin 然后输入用户名和密码(admin/123456);

    二、创建自己项目的执行器:

    1.引入jar包:

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

    注:如果不是maven项目,则需要在idea中运行maven-》install 打出jar包,将jar包引入;

    2.把xxl-job执行器的xxl-job-executor.properties文件copy至项目的resources文件夹下

     

     3.配置xxl-job-executor.properties文件

    # 调度中心地址
    xxl.job.admin.addresses=http://127.0.0.1:8080/xxl-job-admin
     
    #执行器"AppName"和地址信息配置:AppName执行器心跳注册分组依据;地址信息用于"调度中心请求并触发任务"和"执行器注册"。执行器默认端口为9999,执行器IP默认为空表示自动获取IP,多网卡时可手动设置指定IP,该IP不会绑定Host仅作为通讯实用。单机部署多个执行器时,注意要配置不同执行器端口;
     
    xxl.job.executor.appname=task-demo02
    xxl.job.executor.ip=
    xxl.job.executor.port=9998
    ​
    #执行器通讯TOKEN,非空时启用
    xxl.job.accessToken=
    #xxl-job log path执行器运行日志文件存储的磁盘位置,需要对该路径拥有读写权限
    xxl.job.executor.logpath=/data/applogs/xxl-job/jobhandler
    #xxl-job log retention days执行器Log文件定期清理功能,指定日志保存天数,日志文件过期自动删除。限制至少保持3天,否则功能不生效;
    xxl.job.executor.logretentiondays=30

    4.配置applicationContext.xml文件

     5.载入配置文件,在项目中创建 XxlJobConfig.class 文件:

    package com.taskDemo.core.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;
     
    /**
     * xxl-job config
     *
     * @author xuxueli 2017-04-28
     */
    @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}")
        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;
        }
     
        /**
         * 针对多网卡、容器内部署等情况,可借助 "spring-cloud-commons" 提供的 "InetUtils" 组件灵活定制注册IP;
         *
         *      1、引入依赖:
         *          <dependency>
         *             <groupId>org.springframework.cloud</groupId>
         *             <artifactId>spring-cloud-commons</artifactId>
         *             <version>${version}</version>
         *         </dependency>
         *
         *      2、配置文件,或者容器启动变量
         *          spring.cloud.inetutils.preferred-networks: 'xxx.xxx.xxx.'
         *
         *      3、获取IP
         *          String ip_ = inetUtils.findFirstNonLoopbackHostInfo().getIpAddress();
         */
     
     
    }

    6.创建任务JobHandler

    package com.taskDemo.service.jobhandler;
     
    import com.xxl.job.core.biz.model.ReturnT;
    import com.xxl.job.core.handler.IJobHandler;
    import com.xxl.job.core.handler.annotation.XxlJob;
    import com.xxl.job.core.log.XxlJobLogger;
    import org.springframework.stereotype.Component;
     
    /**
     * @Description 调度任务类
     * @Date Created in 下午8:19 2020/2/15
     * @Version 1.0
     */
    @Component
    public class TaskHandler extends IJobHandler {
     
        @XxlJob("taskDemoHandler")
        @Override
        public ReturnT<String> execute(String param) throws Exception {
            XxlJobLogger.log("接受参数" + param +"
    执行任务");
            return SUCCESS;
        }
    }

    7.在调度任务中心配置执行器

    点击执行器管理-->新增执行器 注意AppName为执行器项目应用名,即上面参数xxl.job.executor.appname=task-demo02

     8.创建任务

    点击任务管理-->新增 执行器下拉列表选择刚新增的执行器 注意JobHandler为上面调度任务类@JobHandler(value="taskDemoHandler")中value值

    1. <dependency>
    2.  
      <groupId>com.xuxueli</groupId>
    3.  
      <artifactId>xxl-job-core</artifactId>
    4.  
      <version>2.1.2</version>
    5.  
      </dependency>
