该博客主要介绍了Spring定时器的配置与使用。首先说明了引入定时器所需的Maven依赖，接着展示了定时器对应的方法类书写，最后给出了Spring配置对应的环境变量，包括不同方式的定时器配置示例，如CronTrigger和SimpleTrigger等。

1、引入定时器需要引入的maven依赖

<dependency>
   <groupId>org.quartz-scheduler</groupId>
   <artifactId>quartz</artifactId>
   <version>1.8.5</version>
</dependency>
<dependency>
   <groupId>org.springframework</groupId>
   <artifactId>spring-context-support</artifactId>
   <version>3.2.4.RELEASE</version>
</dependency>

2、书写定时器对应的定时器的方法类

package com.zero.utils;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.URL;
import java.util.Date;
import java.util.Properties;

import org.apache.log4j.Logger;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.springframework.scheduling.quartz.QuartzJobBean;

/**

* @author haijie.peng
* @time 2019年5月6日09:39:07
* @deprecated 定时器定时调用第三方程序
*/
public class TaskOne extends QuartzJobBean {

   private static Logger log = Logger.getLogger(TaskOne.class.getClass());
   private int timeout;
public void setTimeout(int timeout) {
this.timeout = timeout;
}
   @Override
   protected void executeInternal(JobExecutionContext arg0) throws JobExecutionException {
       Properties properties = new Properties();
       ClassLoader classLoader = TaskOne.class.getClassLoader();
URL resource = classLoader.getResource("db.properties");
String path = resource.getPath();
InputStream resourceAsStream = classLoader.getResourceAsStream("db.properties");
try {
properties.load(resourceAsStream);
} catch (IOException e) {
e.printStackTrace();
}
String urlPath = properties.getProperty("thridApp");
log.info("-----upLoad video-----"+new Date()+"------------------------"+properties.getProperty("thirdApp"));
runThirdApp(urlPath);
   }

//调用指令方法，没有用到的话请自觉注解
public static Integer runThirdApp(String code){
Integer num = null;
StringBuilder sb = new StringBuilder();
try {
String[] cmds = {code};
Process pro = Runtime.getRuntime().exec(cmds);
pro.waitFor();
InputStream in = pro.getInputStream();
BufferedReader reade = new BufferedReader(new InputStreamReader(in));
String lin = null;
while ((lin = reade.readLine()) != null) {
if(lin!=null) {
sb.append(lin);
}

}
pro.waitFor();
in.close();
reade.close();
log.info("The ThirdApp run result is"+sb.toString()+"----------"+new Date());
}catch (Exception e) {
e.printStackTrace();
}
return num;
}
}

3、spring配置对应的环境变量

<bean id="cronTrigger"
       class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
       <property name="jobDetail" ref="exampleJob" />
       <property name="cronExpression" value="0 0 6 * * ?" />
       <property name="cronExpression" value="0 0/10 * * * ?" />
       <property name="cronExpression" value="0/120 * * * * ?" />
   </bean>
