java中spring 定時任務實作程式碼

複製代碼代碼如下:

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("處理任務開始>........");
// 業務邏輯程式碼調用
System.out.println("時間[" + new java.util.Date().toLocaleString()
+ "]----->大家好啊！");
log.info("處理任務結束!");
} catch (Exception e) {
log.error("處理任務出現異常", e);
}
}

}

複製代碼代碼如下:

<?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>
<!-- 配置觸發器-->
<bean id="cronTrigger">
<!-- 這裡不可以直接在屬性jobDetail中引用taskJob，因為他要求的是一個jobDetail類型的對象，所以我們得透過MethodInvokingJobDetailFactoryBean來轉一下-->
<property name="jobDetail">
<ref bean="methodInvokingJobDetail" />
</property>
<!-- 每天的8點到21點每隔1分鐘觸發，具體說明請見附錄-->
<property name="cronExpression">
<value>0 * 08-21 * * ?</value>
</property>

</bean>

<bean>
<!-- 新增觸發器-->
<property name="triggers">
<list>
<ref local="cronTrigger" />
</list>
</property>
</bean>

</beans>

複製代碼代碼如下:

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("載入spring設定檔....");
ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");
System.out.println("載入設定檔完成!");
// ApplicationContext context2 = new ClassPathXmlApplicationContext("test/timerTask/quartzTimer.xml");
}
}

複製代碼代碼如下:

<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>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
