spring 定时器

1.配置好的Spring MVC 环境。

 

2.web.xml 添加如下文件：

<servlet>
    <servlet-name>SpringMVC</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <!-- 配置springMVC需要加载的配置文件-->
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:spring-*.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
    <async-supported>true</async-supported>
  </servlet>

用来读取src 目录下所有的文件

3。在对应的配置文件中添加如下代码：（注意XSD 配置和 ）

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:p="http://www.springframework.org/schema/p"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xmlns:task="http://www.springframework.org/schema/task"
       xsi:schemaLocation="
    http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
    http://www.springframework.org/schema/context
    http://www.springframework.org/schema/context/spring-context-3.2.xsd
    http://www.springframework.org/schema/mvc
    http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd
    http://www.springframework.org/schema/task
    http://www.springframework.org/schema/task/spring-task-3.2.xsd">

    <!-- 扫描web相关的bean -->
    <context:component-scan base-package="com.chatRobot.controller"/>

    <!-- 开启SpringMVC注解模式 -->
    <mvc:annotation-driven/>

    <!-- 静态资源默认servlet配置 -->
    <mvc:default-servlet-handler/>

    <!-- 配置jsp 显示ViewResolver -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
        <property name="prefix" value="/WEB-INF/views/"/>
        <property name="suffix" value=".jsp"/>
    </bean>


    <!-- 增加定时任务插件 -->
    <context:annotation-config></context:annotation-config>
    <!-- spring 扫描注解配置 -->
    <context:component-scan base-package="com.lin.quartz"></context:component-scan>
    <!-- 开启这个配置 spring才能识别@Scheduled注解 -->
    <task:annotation-driven scheduler="qbScheduler" mode="proxy"/>
    <task:scheduler id="qbScheduler" pool-size="10"/>

</beans>

3. 添加配置好的testTask 文件。

package com.lin.quartz;



import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;

import java.io.IOException;


@Component("taskJob")
public class QuartzTask {






    @Scheduled(cron = "*/5 * * * * ?")
    public void testTask() throws IOException{
        //封装post 信息
    /*    String  kw="%E8%91%AB%E8%8A%A6%E4%BE%A0";
        String  pnd="MjA=";
        String  sid="0";
//        App.PostDatas(kw,pnd,sid);
        App.PostDatas(kw,pnd,sid);*/
        System.out.println(System.currentTimeMillis()  );

    }
}
