官方文档：分布式任务调度平台XXL-JOB

和@Scheduled区别：

xxljob使用：xxljob分布式任务调度组件 - 简书

1.引入依赖

com.xuxueli xxl-job-core 2.1.1-SNAPSHOT

2.继承IJobHandler

3.声明为bean，使用注解@Component

4.注册到执行器工厂：添加“@JobHandler(value="自定义jobhandler名称")”注解，注解value值对应的是调度中心新建任务的JobHandler属性的值。

5.业务自定义

@Slf4j @JobHandler(value = "xxJobhandler") @Component public class HttpJobHandler extends IJobHandler { @Override public ReturnT execute(String param) throws Exception { //此处编写代码逻辑 } }

6.配置代码

@Configuration @Slf4j public class XxlJobConfig { @Value("${xxl.job.admin.addresses}") private String adminAddresses; @Value("${xxl.job.executor.appname}") private String appName; @Value("${xxl.job.executor.ip:#{null}}") private String ip; @Value("${xxl.job.executor.port}") private int port; @Value("${xxl.job.accessToken:#{null}}") private String accessToken; @Value("${xxl.job.executor.logpath}") private String logPath; @Value("${xxl.job.executor.logretentiondays}") private int logRetentionDays; @Bean(initMethod = "start", destroyMethod = "destroy") public XxlJobSpringExecutor xxlJobExecutor() { log.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; } }
