XXL-Job使用GLUE(Java)调度REST接口

这里就不介绍xxl-job的使用教程了,很简单很好用。
本次仅仅分享使用xxl-job调用REST接口的过程。

首先xxl-job-admin你应该先跑起来,然后新建一个SpringBoot项目里面加上xxl-job的依赖,xxl-job的config等配置信息

Maven中加入xxl-job-core的依赖
<!-- ===========XXL-JOB-CORE=============== -->
		<dependency>
			<groupId>com.xuxueli</groupId>
			<artifactId>xxl-job-core</artifactId>
			<version>2.1.0</version>
		</dependency>
		

application.properties追加以下内容


xxl.job.admin.address = http://127.0.0.1:8080/xxl-job-admin
xxl.job.executor.appname = rone-spark
xxl.job.executor.ip = 127.0.0.1
xxl.job.executor.port = 9999
xxl.job.executor.logpath = /data/applogs/xxl-job/jobhandler
xxl.job.executor.logretentiondays = -1

然后在新建一个xxl-job-config类

package com.rone.demo.XXLJob;



import com.xxl.job.core.executor.impl.XxlJobSpringExecutor;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;


@Configuration
public class XxlJobConfig {
    private Logger logger = LoggerFactory.getLogger(XxlJobConfig.class);

    @Value("${xxl.job.admin.address}")
    private String adminAddresses ;//="http://localhost:8080/xxl-job-admin" ;

    @Value("${xxl.job.executor.appname}")
    private String appName ;//="RoneDemo";

    @Value("${xxl.job.executor.ip}")
    private String ip ;//= "127.0.0.1";

    @Value("${xxl.job.executor.port}")
    private int port ;//= 9999;

   /* @Value("${xxl.job.accessToken}")*/
    private String accessToken;

    @Value("${xxl.job.executor.logpath}")
    private String logPath ;

    //@Value("${xxl.job.executor.logretentiondays}")
    private int logRetentionDays = -1;


    @Bean(initMethod = "start", destroyMethod = "destroy")
    public XxlJobSpringExecutor xxlJobExecutor() {
        logger.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;
    }

}

这里注意

import org.springframework.http.*;
import org.springframework.web.client.RestTemplate;

这两个依赖是SpringBoot调用REST接口的包,因为我们要call REST所以要使用这两个依赖,一定要加上

package com.rone.demo.XXLJob;


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;
import org.springframework.http.*;
import org.springframework.web.client.RestTemplate;
/**
 * 任务Handler示例(Bean模式)
 *
 * 开发步骤:
 * 1、继承"IJobHandler":“com.xxl.job.core.handler.IJobHandler”;
 * 2、注册到Spring容器:添加“@Component”注解,被Spring容器扫描为Bean实例;
 * 3、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。
 * 4、执行日志:需要通过 "XxlJobLogger.log" 打印执行日志;
 */
@JobHandler(value="sparkJobHandler")
@Component
public class RunSparkHandler extends IJobHandler {


    @Override
    public ReturnT<String> execute(String warPath) throws Exception {
        XxlJobLogger.log("============================Run Spark Job=======================");
        XxlJobLogger.log("war Path : =================" + warPath);
        XxlJobLogger.log("============================Call Successfully=======================");

        return SUCCESS;
    }
}

接着就是直接run了,新建执行器,appName一定要与application.properties里面配置的一样,还有机器地址与端口要与配置文件中的一致

新建一个任务,选择我们刚刚建立的执行器,运行模式选择GLUE(Java),其它的参照一下就好。

XXL-Job使用GLUE(Java)调度REST接口_第3张图片我们会新开一个标签页,在新开的见面写我们需要call的端口与地址
XXL-Job使用GLUE(Java)调度REST接口_第4张图片这里是详细代码,由于隐私问题我把Spark地址与端口改成了example请见谅

package com.xxl.job.service.handler;

import com.xxl.job.core.log.XxlJobLogger;
import com.xxl.job.core.biz.model.ReturnT;
import com.xxl.job.core.handler.IJobHandler;

//注意这里是我们在excutor中引入的两个RestTemplate相关包
import org.springframework.http.*;
import org.springframework.web.client.RestTemplate;


public class DemoGlueJobHandler extends IJobHandler {

  	 String LIVY_HOST = "http://192.168.1.1";
     String HDFS_HOST = "cdh01";//192.168.1.1
     String LIVY_PORT = "8990";
     String HDFS_PORT = "50070";
     String SESSIONS = "sessions";
     String STATEMENTS = "statements";
     String BATCHES = "batches";
  
 	 
  
	@Override
	public ReturnT<String> execute(String param) throws Exception {
		XxlJobLogger.log("Test RestFull");
        RestTemplate client = new RestTemplate();
        HttpHeaders headers = new HttpHeaders();
      
        String pData = "{\"file\":\"hdfs://"+HDFS_HOST+":"+HDFS_PORT+"/user/spark/SparkLR.jar\",\"className\":\"com.rone.DBUtils.MySQLOperations\"}";

        HttpEntity<String> entity = new HttpEntity<>(pData,headers);
        ResponseEntity<Map> resp = client.exchange(LIVY_HOST+":"+LIVY_PORT+"/"+BATCHES+"/", HttpMethod.POST, entity, Map.class);
		return ReturnT.SUCCESS;
	}

}

在这里插入图片描述
然后测试执行就OK了,
