分布式任务调度平台XXL-JOB
一、下载源码
github 地址:https://github.com/xuxueli/xxl-job/releases
gitee 地址:http://gitee.com/xuxueli0323/xxl-job/releases
文档地址:https://www.xuxueli.com/xxl-job/
二、初始化“调度数据库”
三、运行 xxl-job-admin
先修改 properties 文件中的数据库密码,改成自己的。
运行
四、打开管理后台
网址输入 http://localhost:8080/xxl-job-admin/
五、创建执行器
六、创建任务
七、项目中使用
-
pom.xml 添加依赖
1 <!-- https://mvnrepository.com/artifact/com.xuxueli/xxl-job-core --> 2 <dependency> 3 <groupId>com.xuxueli</groupId> 4 <artifactId>xxl-job-core</artifactId> 5 <version>2.3.0</version> 6 </dependency>
-
yml 文件添加配置
1xxl: 2 job: 3 admin: 4 addresses: http://127.0.0.1:8080/xxl-job-admin 5 accessToken: 6 executor: 7 appname: study-executor 8 address: 9 ip: 127.0.0.1 10 port: 9999 11 logpath: E:/ws/xxl-job-2.3.0/data/applogs/xxl-job/jobhandler 12 logretentiondays: 3000
-
创建配置文件
1package com.zxy.demo.config; 2 3import com.xxl.job.core.executor.impl.XxlJobSpringExecutor; 4import org.slf4j.Logger; 5import org.slf4j.LoggerFactory; 6import org.springframework.beans.factory.annotation.Value; 7import org.springframework.context.annotation.Bean; 8import org.springframework.context.annotation.Configuration; 9 10/** 11 * xxl-job config 12 * 13 * @author xuxueli 2017-04-28 14 */ 15@Configuration 16public class XxlJobConfig { 17 private Logger logger = LoggerFactory.getLogger(XxlJobConfig.class); 18 19 @Value("${xxl.job.admin.addresses}") 20 private String adminAddresses; 21 22 @Value("${xxl.job.accessToken}") 23 private String accessToken; 24 25 @Value("${xxl.job.executor.appname}") 26 private String appname; 27 28 @Value("${xxl.job.executor.address}") 29 private String address; 30 31 @Value("${xxl.job.executor.ip}") 32 private String ip; 33 34 @Value("${xxl.job.executor.port}") 35 private int port; 36 37 @Value("${xxl.job.executor.logpath}") 38 private String logPath; 39 40 @Value("${xxl.job.executor.logretentiondays}") 41 private int logRetentionDays; 42 43 44 @Bean 45 public XxlJobSpringExecutor xxlJobExecutor() { 46 logger.info(">>>>>>>>>>> xxl-job config init."); 47 XxlJobSpringExecutor xxlJobSpringExecutor = new XxlJobSpringExecutor(); 48 xxlJobSpringExecutor.setAdminAddresses(adminAddresses); 49 xxlJobSpringExecutor.setAppname(appname); 50 xxlJobSpringExecutor.setAddress(address); 51 xxlJobSpringExecutor.setIp(ip); 52 xxlJobSpringExecutor.setPort(port); 53 xxlJobSpringExecutor.setAccessToken(accessToken); 54 xxlJobSpringExecutor.setLogPath(logPath); 55 xxlJobSpringExecutor.setLogRetentionDays(logRetentionDays); 56 57 return xxlJobSpringExecutor; 58 } 59 60 /** 61 * 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; 62 * 63 * 1、引入依赖: 64 * <dependency> 65 * <groupId>org.springframework.cloud</groupId> 66 * <artifactId>spring-cloud-commons</artifactId> 67 * <version>${version}</version> 68 * </dependency> 69 * 70 * 2、配置文件,或者容器启动变量 71 * spring.cloud.inetutils.preferred-networks: 'xxx.xxx.xxx.' 72 * 73 * 3、获取IP 74 * String ip_ = inetUtils.findFirstNonLoopbackHostInfo().getIpAddress(); 75 */ 76 77 78}

创建任务,注意:@XxlJob 注解中的值需与自己创建的执行器名称一致
1package com.zxy.demo.job; 2 3import com.xxl.job.core.biz.model.ReturnT; 4import com.xxl.job.core.handler.annotation.XxlJob; 5import org.springframework.stereotype.Component; 6 7/** 8 * @description: study 9 * 模块名称: 10 * 说明: 11 * 作者(@author): zxy 12 * 创建日期: 2022年3月2日16:52:16 13 */ 14 15@Component 16public class StudyTestJobHandler { 17 18 @XxlJob("studyTestJobHandler") 19 public ReturnT<String> shardingJobHandler() { 20 21 System.out.println("定时任务执行。。。。。"); 22 return ReturnT.SUCCESS; 23 } 24} 25
