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。 add-executor-image.png

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。 executor-info-image.png

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: add-task-image.png

执行调度任务

启动调度任务,查看调度日志。
