springMVC第一个案例---hellospringMVC ......

  

   1.导入jar包

    commons-logging-1.1.1.jar

    jackson-annotations-2.5.4.jar

    jackson-core-2.5.4.jar

    jackson-databind-2.5.4.jar

    spring-aop-4.1.6.release.jar

    spring-beans-4.1.6.release.jar

    spring-context-4.1.6.release.jar

    spring-core-4.1.6.release.jar

    spring-expression-4.1.6.release.jar

    spring-tx-4.1.6.release.jar

    spring-web-4.1.6.release.jar

    spring-webmvc-4.1.6.release.jar

 

  2.配置web.xml-配置分发器,在web.xml文件添加如下代码

  <servlet>
        <servlet-name>springmvc</servlet-name>
        <servlet-class>org.springframework.web.servlet.dispatcherservlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>springmvc</servlet-name>
        <url-pattern>*.do</url-pattern>
    </servlet-mapping>

 

 

  3.添加springmvc配置文件,添加到web-inf目录下,名称规范:[dispatcherservlet]-servlet.xml,本案例为:springmvc-servlet.xml

 

  4.编写控制器类hellocontroller,实现controller接口

package com.ahd.controller;

import javax.servlet.http.httpservletrequest;
import javax.servlet.http.httpservletresponse;

import org.springframework.web.servlet.modelandview;
import org.springframework.web.servlet.mvc.controller;

public class hellocontroller implements controller{

    public modelandview handlerequest(httpservletrequest req,
            httpservletresponse resp) throws exception {
        // todo auto-generated method stub
        modelandview mv=new modelandview();
        
        //设置要显示到视图的信息
        mv.addobject("msg", "hello springmvc");
        //设置视图名称
        mv.setviewname("hello");
        
        return mv;
    }

}

 

  5.编写springmvc配置文件

<?xml version="1.0" encoding="utf-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"
    xmlns:p="http://www.springframework.org/schema/p"
    xsi:schemalocation="
        http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd">

<!-- 配置handlermapping --> <bean class=" org.springframework.web.servlet.handler.beannameurlhandlermapping"></bean> <!-- 配置handleradapter --> <bean class="org.springframework.web.servlet.mvc.simplecontrollerhandleradapter"></bean> <!-- 配置渲染器 --> <bean id="jspviewresolver" class="org.springframework.web.servlet.view.internalresourceviewresolver"> <property name="viewclass" value="org.springframework.web.servlet.view.jstlview"/> <!-- 将视图名 渲染后视图的前缀 --> <property name="prefix" value="/web-inf/jsp/"/> <!-- 渲染后视图的后缀 --> <property name="suffix" value=".jsp"/> <!-- 例:视图名为:hello 渲染后:/web-inf/jsp/hello.jsp 该页面--> </bean> <!-- 配置请求和处理器 --> <bean name="/hello.do" class="com.ahd.controller.hellocontroller"></bean>

</beans>
