SpringBoot整合Xxl-Job的完整步骤记录

一、下载Xxl-Job源代码并导入本地并运行

Github地址:
https://github.com/xuxueli/xxl-job

中文文档地址:
https://www.xuxueli.com/xxl-job/

1.使用Idea或Eclipse导入

2.执行sql脚本(红色标记处)

3.运行xxl-job-admin(xxl-job后台管理,主要方便管理各种各样的任务)

注意:在运行之前,需要把2的sql脚本执行完毕,并修改数据库连接池。

正常启动,访问地址为:http://localhost:8080/xxl-job-admin

效果图,如下所示:

用户名默认为admin

密码为123456

输入后,进入这个界面,如图:

这样就表示Xxl-Job成功运行了。确保运行没问题后,就可以开始下一步。

二、添加执行器(Xxl-Job源代码就一个Example,可以复用过来,你也可以选择自己新建项目,新建项目可以在Xxl-Job基础上,也可以放在其它项目中)

1.新建一个Maven项目,命名为blog-xxl-job。

2.导入Maven依赖


  
   com.xuxueli
   xxl-job-core
   2.2.0
  
  
   org.springframework.cloud
   spring-cloud-starter-netflix-eureka-client
  
  
   org.springframework.boot
   spring-boot-starter-web
  

3.新建application.yml配置文件并添加如下内容

#eureka
eureka.client.serviceUrl.defaultZone=http://localhost:8761/eureka/
# web port
server.port=8081
# no web
#spring.main.web-environment=false
# log config
logging.config=classpath:logback.xml
### xxl-job admin address list, such as "http://address" or "http://address01,http://address02"
xxl.job.admin.addresses=http://127.0.0.1:8080/xxl-job-admin
### xxl-job, access token
xxl.job.accessToken=
### xxl-job executor appname
xxl.job.executor.appname=blog-xxl-job-executor
### xxl-job executor registry-address: default use address to registry , otherwise use ip:port if address is null
xxl.job.executor.address=
### xxl-job executor server-info
xxl.job.executor.ip=
xxl.job.executor.port=9999
### xxl-job executor log-path
xxl.job.executor.logpath=/data/applogs/xxl-job/jobhandler
### xxl-job executor log-retention-days
xxl.job.executor.logretentiondays=30

可以不用eureka,这里我的项目中用到eureka所以增加该配置。

增加logback.xml配置:




 logback
 

 
  
   %d{HH:mm:ss.SSS} %contextName [%thread] %-5level %logger{36} - %msg%n
  
 

 
  ${log.path}
  
   ${log.path}.%d{yyyy-MM-dd}.zip
  
  
   %date %level [%thread] %logger{36} [%file : %line] %msg%n
   
  
 

 
  
  
 

4.编写Application类

package com.springcloud.blog.job.execute;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;

@EnableEurekaClient
@EnableDiscoveryClient
@SpringBootApplication
public class BlogXxlJobExecutorApplication {
 public static void main(String[] args) {
  SpringApplication.run(BlogXxlJobExecutorApplication.class, args);
 }

}

5.编写Job执行器

package com.springcloud.blog.job.execute.jobhandler;

import com.xxl.job.core.biz.model.ReturnT;
import com.xxl.job.core.handler.IJobHandler;
import com.xxl.job.core.handler.annotation.XxlJob;
import com.xxl.job.core.log.XxlJobLogger;
import com.xxl.job.core.util.ShardingUtil;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Component;

import java.io.BufferedInputStream;
import java.io.BufferedReader;
import java.io.DataOutputStream;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;
import java.util.Arrays;
import java.util.concurrent.TimeUnit;

/**

 * 

* 开发步骤: * 1、在Spring Bean实例中,开发Job方法,方式格式要求为 "public ReturnT execute(String param)" * 2、为Job方法添加注解 "@XxlJob(value="自定义jobhandler名称", init = "JobHandler初始化方法", destroy = "JobHandler销毁方法")",注解value值对应的是调度中心新建任务的JobHandler属性的值。 * 3、执行日志:需要通过 "XxlJobLogger.log" 打印执行日志; * * @author xuxueli 2019-12-11 21:52:51 */ @Component public class SampleXxlJob { private static Logger logger = LoggerFactory.getLogger(SampleXxlJob.class); /** * 1、简单任务示例(Bean模式) */ @XxlJob("demoJobHandler") public ReturnT demoJobHandler(String param) throws Exception { XxlJobLogger.log("XXL-JOB, Hello World.");

} } /** * 4、跨平台Http任务 * 参数示例: * "url: http://www.baidu.com\n" + * "method: get\n" + * "data: content\n"; */ @XxlJob("httpJobHandler") public ReturnT httpJobHandler(String param) throws Exception { // param parse if (param == null || param.trim().length() == 0) { XxlJobLogger.log("param[" + param + "] invalid."); return ReturnT.FAIL; } String[] httpParams = param.split("\n"); String url = null; String method = null; String data = null; for (String httpParam : httpParams) { if (httpParam.startsWith("url:")) { url = httpParam.substring(httpParam.indexOf("url:") + 4).trim(); } if (httpParam.startsWith("method:")) { method = httpParam.substring(httpParam.indexOf("method:") + 7).trim().toUpperCase(); } if (httpParam.startsWith("data:")) { data = httpParam.substring(httpParam.indexOf("data:") + 5).trim(); } } // param valid if (url == null || url.trim().length() == 0) { XxlJobLogger.log("url[" + url + "] invalid."); return ReturnT.FAIL; } if (method == null || !Arrays.asList("GET", "POST").contains(method)) { XxlJobLogger.log("method[" + method + "] invalid."); return ReturnT.FAIL; } // request HttpURLConnection connection = null; BufferedReader bufferedReader = null; try { // connection URL realUrl = new URL(url); connection = (HttpURLConnection) realUrl.openConnection();

// do connection connection.connect(); // data if (data != null && data.trim().length() > 0) { DataOutputStream dataOutputStream = new DataOutputStream(connection.getOutputStream()); dataOutputStream.write(data.getBytes("UTF-8")); dataOutputStream.flush(); dataOutputStream.close(); } // valid StatusCode int statusCode = connection.getResponseCode(); if (statusCode != 200) { throw new RuntimeException("Http Request StatusCode(" + statusCode + ") Invalid."); } // result bufferedReader = new BufferedReader(new InputStreamReader(connection.getInputStream(), "UTF-8")); StringBuilder result = new StringBuilder(); String line; while ((line = bufferedReader.readLine()) != null) { result.append(line); } String responseMsg = result.toString(); XxlJobLogger.log(responseMsg); return ReturnT.SUCCESS; } catch (Exception e) { XxlJobLogger.log(e); return ReturnT.FAIL; } finally { try { if (bufferedReader != null) { bufferedReader.close(); } if (connection != null) { connection.disconnect(); } } catch (Exception e2) { XxlJobLogger.log(e2); } } } /** * 5、生命周期任务示例:任务初始化与销毁时,支持自定义相关逻辑; */ @XxlJob(value = "demoJobHandler2", init = "init", destroy = "destroy") public ReturnT demoJobHandler2(String param) throws Exception { XxlJobLogger.log("XXL-JOB, Hello World."); return ReturnT.SUCCESS; } public void init() { logger.info("init"); } public void destroy() { logger.info("destory"); } }

6.增加XxlJobConfig配置类

package com.springcloud.blog.job.execute.core.config;

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.addresses}")
 private String adminAddresses;

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

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

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

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

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

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

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


 @Bean
 public XxlJobSpringExecutor xxlJobExecutor() {
  logger.info(">>>>>>>>>>> xxl-job config init.");
  XxlJobSpringExecutor xxlJobSpringExecutor = new XxlJobSpringExecutor();
  xxlJobSpringExecutor.setAdminAddresses(adminAddresses);
  xxlJobSpringExecutor.setAppname(appname);
  xxlJobSpringExecutor.setAddress(address);
  xxlJobSpringExecutor.setIp(ip);
  xxlJobSpringExecutor.setPort(port);
  xxlJobSpringExecutor.setAccessToken(accessToken);
  xxlJobSpringExecutor.setLogPath(logPath);
  xxlJobSpringExecutor.setLogRetentionDays(logRetentionDays);

  return xxlJobSpringExecutor;
 }


}

三、结合Xxl-Job后台系统增加定时任务

1.配置执行器

执行器地址为(与blog-xxl-job中application.yml配置文件里的执行器地址需要保持一致,否则会注册失败,导致任务执行不了:

2.添加任务

3.任务执行成功的标志

四、为什么选择Xxl-Job

当初选择使用Xxl-Job有这么几个原因:

第一、团队里有好几个人上一家公司或上上家公司用过。

第二、这个生态比较丰富且开源。

第三、确实非常容易上手且轻量化(轻量化的一个体现就是非侵入式)
