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
创建一个Spring Boot项目
<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>
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
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;
}
}
在调度中心->执行器管理中增加执行器。

在调度中心->任务管理中添加一个调度任务,配置如下图:
启动调度任务,查看调度日志。
