前段时间项目上需要用到任务调度，对比了Quartz的不足与XXL-JOB优缺点，整体上：XXL-JOB比Quartz更轻量化，更易上手，还具有可视化界面以及在任务调度、日志管理、弹性扩容缩容、执行器HA（分布式）、邮件报警、运行报表、全异步、跨平台、国际化、容器化、线程池隔离等方面更加人性化。
一、源码下载地址：
下载xxl-job源码
xxl-job源码地址：
只需要将数据库配置成自己的，然后生成jar包即可，XXL-JOB的管理器直接通过运行jar包就正常运行；例如：
启动后效果图：
运行效果如下：
主页面：
执行器：
调度日志：
用户名密码在用户（xxl_job_user）表中；
二、数据库表创建：
基本支撑的表包括：
有需要建表语句的请关注公众号后留言即可；
三、集成到项目：
需要本地工程修改的代码类以及配置文件：XxlJobConfig.java、SampleXxlJob.java、application.properties、logback.xml
核心代码如下：
XxlJobConfig.java(直接copy到工程即可)
package www.tonghao.com.xxl.job.executor.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;
/**
* Create by YSOcean
*/
@Configuration
public class XxlJobConfig {
private Logger logger = LoggerFactory.getLogger(XxlJobConfig.class);
@Value(“${xxl.job.admin.addresses}”)
private String adminAddresses;
@Value(“${xxl.job.executor.appname}”)
private String appName;
@Value(“${xxl.job.executor.ip}”)
private String ip;
@Value(“${xxl.job.executor.port}”)
private int port;
@Value(“${xxl.job.accessToken}”)
private String accessToken;
@Value(“${xxl.job.executor.logpath}”)
private String logPath;
@Value(“${xxl.job.executor.logretentiondays}”)
private int logRetentionDays;
// @Bean(initMethod = “start”, destroyMethod = “destroy”)
@Bean
public XxlJobSpringExecutor xxlJobExecutor() {
logger.info(“>>>>>>>>>>> xxl-job config init.”);
XxlJobSpringExecutor xxlJobSpringExecutor = new XxlJobSpringExecutor();
xxlJobSpringExecutor.setAdminAddresses(adminAddresses);
// xxlJobSpringExecutor.setAddress(address);
xxlJobSpringExecutor.setAppname(appName);
xxlJobSpringExecutor.setIp(ip);
xxlJobSpringExecutor.setPort(port);
xxlJobSpringExecutor.setAccessToken(accessToken);
xxlJobSpringExecutor.setLogPath(logPath);
xxlJobSpringExecutor.setLogRetentionDays(logRetentionDays);
return xxlJobSpringExecutor;
}
}
SampleXxlJob.java(调度执行类)
package www.tonghao.com.xxl.job.executor.service.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 org.springframework.stereotype.Component;
import www.tonghao.common.utils.SpringUtil;
import www.tonghao.wc.service.WcinOrdersService;
import www.tonghao.wc.web.WcinOrderApiController;
/**
* 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=”demoJobHandler”)
@Component
public class SampleXxlJob extends IJobHandler{
@XxlJob(“demoJobHandler”)
@Override
public ReturnT<String> execute(String s) throws Exception {
XxlJobLogger.log(“XXL-JOB, Hello World.”);
System.out.println(“This is example!”);
//更换即可–start
WcinOrderApiController contr=new WcinOrderApiController();
String msg=contr.getOrder();
//更换即可–end
return SUCCESS;
}
}
logback.xml(直接copy到工程即可)
<?xml version=”1.0″ encoding=”UTF-8″?>
<configuration debug=”false” scan=”true” scanPeriod=”1 seconds”>
<contextName>logback</contextName>
<property name=”log.path” value=”/data/applogs/xxl-job/xxl-job-executor-sample-springboot.log”/>
<appender name=”console” class=”ch.qos.logback.core.ConsoleAppender”>
<encoder>
<pattern>%d{HH:mm:ss.SSS} %contextName [%thread] %-5level %logger{36} – %msg%n</pattern>
</encoder>
</appender>
<appender name=”file” class=”ch.qos.logback.core.rolling.RollingFileAppender”>
<file>${log.path}</file>
<rollingPolicy class=”ch.qos.logback.core.rolling.TimeBasedRollingPolicy”>
<fileNamePattern>${log.path}.%d{yyyy-MM-dd}.zip</fileNamePattern>
</rollingPolicy>
<encoder>
<pattern>%date %level [%thread] %logger{36} [%file : %line] %msg%n
</pattern>
</encoder>
</appender>
<root level=”info”>
<appender-ref ref=”console”/>
<appender-ref ref=”file”/>
</root>
</configuration>
application.properties（核心配置）
# no web
#spring.main.web-environment=false
# log config
logging.config=classpath:logback.xml
### xxl-job admin address list, such as “#34; or “#34;
xxl.job.admin.addresses=
#xxl.job.admin.addresses=
### xxl-job, access token
xxl.job.accessToken=
### xxl-job executor appname
xxl.job.executor.appname=testgmm
### 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.ip=127.0.0.1
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
至此，XXL-JOB集成到项目，完成；
使用操作的详细配置，后续会更新，请持续关注！！！
