java中 spring 定时任务 实现代码

复制代码代码如下:

import org.apache.log4j.*;
public class TaskJob {
public static Logger log = Logger
.getLogger(TaskJob.class);
public void SayHello() {
// TODO Auto-generated method stub
try {
log.info("处理任务开始>........");
// 业务逻辑代码调用
System.out.println("时间[" + new java.util.Date().toLocaleString()
+ "]----->大家好啊！");
log.info("处理任务结束!");
} catch (Exception e) {
log.error("处理任务出现异常", e);
}
}

}

复制代码代码如下:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
<bean name="taskJob" />

<bean id="methodInvokingJobDetail">
<property name="targetObject">
<ref bean="taskJob" />
</property>
<property name="targetMethod">
<value>SayHello</value>
</property>
</bean>
<!-- 配置触发器 -->
<bean id="cronTrigger">
<!-- 这里不可以直接在属性jobDetail中引用taskJob，因为他要求的是一个jobDetail类型的对象，所以我们得通过MethodInvokingJobDetailFactoryBean来转一下 -->
<property name="jobDetail">
<ref bean="methodInvokingJobDetail" />
</property>
<!-- 每天的8点到21点每隔1分钟触发，具体说明见附录 -->
<property name="cronExpression">
<value>0 * 08-21 * * ?</value>
</property>

</bean>

<bean>
<!-- 添加触发器 -->
<property name="triggers">
<list>
<ref local="cronTrigger" />
</list>
</property>
</bean>

</beans>

复制代码代码如下:

package util;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class TestApp {

public static void main(String[] args) {
// TODO Auto-generated method stub
System.out.println("加载spring配置文件....");
ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");
System.out.println("加载配置文件完毕!");
// ApplicationContext context2 = new ClassPathXmlApplicationContext("test/timerTask/quartzTimer.xml");
}
}

复制代码代码如下:

<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/classes/applicationContext.xml</param-value>
</context-param>
<context-param>
<param-name>log4jConfigLocation</param-name>
<param-value>/WEB-INF/log4j.properties</param-value>
</context-param>
