xxl-job-spring-boot-starter

简述

本项目将xxl-job-core包简单封装成spring boot starter，方便通过Spring Boot方式开发xxl-job的executor

使用方法

添加依赖

创建一个Spring Boot项目

添加依赖包

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
    <version>2.1.4.RELEASE</version>
    <exclusions>
 <!-- exclude tomcat -->  <exclusion>  <groupId>org.springframework.boot</groupId>  <artifactId>spring-boot-starter-tomcat</artifactId>  </exclusion>  </exclusions> </dependency> <dependency>  <groupId>org.springframework.boot</groupId>  <artifactId>spring-boot-starter-undertow</artifactId>  <version>2.1.4.RELEASE</version> </dependency>  <dependency>  <groupId>cn.centychen</groupId>  <artifactId>xxl-job-spring-boot-starter</artifactId>  <version>1.0.1-RELEASE</version> </dependency>

修改xxl-job配置

添加以下xxl-job配置，也可不配置，不配置则使用默认值。

xxl-job:
  admin:
    admin-addresses: http://localhost:8080/xxl-job-admin
  executor:
    app-name: xxl-job-spring-boot-starter-example #默认为 xxl-job-executor
 access-token: #默认为空  log-path: logs/applogs/xxl-job/jobhandler #默认为 logs/applogs/xxl-job/jobhandler  log-retention-days: 10 #默认为 10  ip: #默认为空  port: 9999 #默认为 9999

编写任务处理器

创建DemoJobHandler.class类，继承IJobHandler抽象类，示例代码如下：

import com.xxl.job.core.biz.model.ReturnT;
import com.xxl.job.core.handler.IJobHandler;
import com.xxl.job.core.handler.annotation.JobHandler;
import com.xxl.job.core.log.XxlJobLogger;
import org.springframework.stereotype.Component;
 @JobHandler("demoJobHandler") @Component public class DemoJobHandler extends IJobHandler {   @Override  public ReturnT<String> execute(String s) throws Exception {  XxlJobLogger.log("This is a demo job.");  Thread.sleep(5 * 1000L);  return SUCCESS;  } }

启动测试

添加执行器

在调度中心->执行器管理中增加执行器。

启动执行器

启动示例执行器服务，启动成功log如下：

执行器启动成功后，在调度中心的执行器记录中可以查看到注册信息。

添加调度任务

在调度中心->任务管理中添加一个调度任务，配置如下图：

执行调度任务

启动调度任务，查看调度日志。
