springMVC（二）—— 简单的springmvc的demo

简单的springmvc的demo

1、引入springmvc相关的jar包

2、配置DispatcherServlet 在web.xml

 <servlet>
      <servlet-name>springMVCConfig-servlet</servlet-name>
      <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
       <init-param>
          <param-name>contextConfigLocation</param-name>
          <param-value>classpath:springMVCConfig-servlet.xml</param-value>
      </init-param>
  
  </servlet>
  <servlet-mapping>
      <servlet-name>springMVCConfig-servlet</servlet-name>
      <url-pattern>*.do</url-pattern>
  </servlet-mapping>

3、 配置springmvc的配置文件

创建一个springmvc.xml文件，并配置

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">
    <!-- 配置一个HandlerMapping ，如果自己不配置HandlerMapping，会默认有一个HandlerMapping -->
    <bean class="org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping"></bean>
    <!-- 注册自己的Controller类 -->
　　 <!--根据controller类的名字找到对应的Controller类，类中除了Controller首字母大写，其他的全部小写-->
　　 <bean  class="com.zhiyou100.zjc.controller.ExampleController"></bean>
    <!-- 配置试图解析器 -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/view/"></property>
        <property name="suffix" value=".jsp"></property>
        
    </bean>
</beans>

4、书写Controller

public class ExampleController extends  AbstractController{

    @Override
    protected ModelAndView handleRequestInternal(HttpServletRequest arg0, HttpServletResponse arg1) throws Exception {
        ModelAndView mav = new ModelAndView();
        mav.setViewName("index");
        mav.addObject("info", "Hello SpringMVC");
        return mav;
    }

}

 5、创建jsp文件看，接收信息

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
</head>
<body>
${info }
</body>
</html>

6、网页中输出结果　　

输入http://localhost:8080/day090202/exampleController.do
