使用MyEclipse 搭建 SpringMvc 项目

项目只是单纯的使用了spring的mvc框架, 并没有集成其他模块
- 结构目录
使用 maven 创建web 项目, 调整好结构目录后如下
这里写图片描述
- 需要的jar

配置文件
web.xml
在web 文件中,使用到了servlet模块,用来转发请求到 controller 控制器

<?xml version="1.0" encoding="UTF-8"?><web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee"    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">    <servlet>        <servlet-name>springMvc</servlet-name>        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>        <init-param>            <param-name>contextConfigLocation</param-name>            <param-value>classpath:spring-servlet.xml</param-value>        </init-param>        <load-on-startup>1</load-on-startup>    </servlet>    <servlet-mapping>        <servlet-name>springMvc</servlet-name>        <url-pattern>/</url-pattern>    </servlet-mapping>    <filter>        <filter-name>encodingFilter</filter-name>        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>        <init-param>            <param-name>encoding</param-name>            <param-value>utf-8</param-value>        </init-param>        <init-param>            <param-name>forceEncoding</param-name>            <param-value>true</param-value>        </init-param>    </filter>    <filter-mapping>        <filter-name>encodingFilter</filter-name>        <url-pattern>/*</url-pattern>    </filter-mapping></web-app>

spring-servlet.xml

    <!-- 视图解析器 -->    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">        <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"></property>        <property name="prefix" value="/WEB-INF/jsp/"></property>        <property name="suffix" value=".jsp"></property>    </bean>    <!--注解扫描器,controller  -->       <context:component-scan base-package="com.sinda">         <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller" />         <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Service" />     </context:component-scan>

欢迎界面
在代码里面定义 @controller 注解, 项目会根据用户的url 地址来找相应的模块做处理并返回.

package com.sinda.controller;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;@Controllerpublic class LoginAction {    @RequestMapping("/index")    public String index(){        return "index";    }}
