spring结合Quartz的集群功能实现
一：前沿
在上一篇（http://www.cnblogs.com/wuhao1991/p/4331613.html）的博客中记载了定时的功能，但是集成是没有成功的，在这篇中，我在解释下这里的”集成的含义“，这里的集成是指:比如我有两个tomcat（tomcat1,tomcat2），然后现在我先启动tomcat1,在启动tomcat2，但是定时查询的功能在tomcat1上在执行，但是tomcat2上没有执行；此时我把tomcat1停止调，tomcat2又继续执行这个定时的功能；所以这里的集成说白了就是，定时的功能只能执行一个，这两个tomcat里卖弄是互斥的关系！
二：内容技术
在上一篇中说过，我在配置集群的时候，老是出问题，那么现在我会把这个问题记载下来；下面进行说明吧！
application-quartz.xml配置如下
<?xml version="1.0" encoding="UTF-8" ?>
<beans xmlns="http://www.springframework.org/schema/beans"

<property name="applicationContextSchedulerContextKey" value="applicationContextKey"></property>
<property name="configLocation" value="classpath:quartz.properties"></property>
<property name="autoStartup" value="true" />
</bean>
</beans>
bug如下：

使得我照这个解决方案找了好久好久啊！所以看看下面的截图（http://www.objectpartners.com/2013/07/09/configuring-quartz-2-with-spring-in-clustered-mode/）
就是看完这句话，我才把集成给实验成功的，现在附上正确的代码<?xml version="1.0" encoding="UTF-8" ?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

firstjob.java：
package com.gsh.graduate.quartz; import java.util.Date; import org.quartz.JobExecutionContext; import org.quartz.SchedulerContext; import org.quartz.SchedulerException; import org.springframework.beans.factory.config.BeanDefinition; import org.springframework.context.annotation.Scope; import org.springframework.scheduling.quartz.QuartzJobBean; import org.springframework.stereotype.Component; import com.gsh.graduate.dao.UserDao; import com.gsh.graduate.pojo.User; @Component @Scope(value = BeanDefinition.SCOPE_PROTOTYPE) public class FirstJob extends QuartzJobBean {
// @AutoWire
// private UserDao userDao
private UserDao userDao;
public void setUserDao(UserDao userDao) { this.userDao = userDao; } @Override protected void executeInternal(JobExecutionContext context) { //获取JobExecutionContext中的service对象 try { SchedulerContext skedCtx = context.getScheduler().getContext(); userDao=(UserDao) skedCtx.get("userDao"); } catch (SchedulerException e) { e.printStackTrace(); } User u=userDao.getUserByID("12345"); System.out.println("---"+u); System.out.println("定时开始0,1,2,3"); System.out.println(new Date()); System.out.println("定时结束,game over"); } }
特别说明：这里面的对象必须在配置文件里面声明，在firstjob.java类中，如果你想通过这样像代码中注释的那样，自动注入会报一下错误；所以可以看下spring 通过配置向quartz 注入service（http://blog.csdn.net/whaosy/article/details/6298686）

上面第一次实验的那种bug本来有两种配置方式的，但是我在配置好了之后，实验以前的没有报bug，我都郁闷了，附加代码看看

三：总结，折腾了这么久终于把集成给折腾成功了啊，这是接触新鲜的东西，就是不一样啊，解决问题的能力还是有涨进的啊！继续Go!Boy，今天一下在把有关Quartz的都写了！不枉我研究了两天啊！
