定时任务之@JobHandler

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

<dependency>
<groupId>com.xuxueli</groupId>
<artifactId>xxl-job-core</artifactId>
<version>2.1.1-SNAPSHOT</version>
</dependency>
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<String> 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;
}
}
