spring学习（1）Spring MVC框架搭建

Spring MVC框架搭建
一、为什么要使用Spring MVC

1、 struts2的漏洞太多，且其官方不负责的态度（2013年7月17日直接对外公布其漏洞代码，导致很多网站被攻击）。

2、 springmvc学习难度小，架构灵活，性能高于struts2。

二、需要在pom.xml文件中引入的jar

<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>3.2.3.RELEASE</version>
</dependency>

三、web.xml文件的配置

<!-- spring mvcservlet拦截器 -->
<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>

<!-- 指定spring的配置文件 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
/WEB-INF/spring/*.xml
</param-value>
</context-param>
<!-- 指定以Listener方式启动Spring容器
-->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!-- 指定以Listener方式启动Log4j -->
<listener>
<listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
</listener>

<!-- 指定spring编码过滤器 -->
<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>

四、加入spring mvc过滤配置文件springmvc-servlet.xml

<?xmlversion="1.0"encoding="UTF-8"?>
<beansxmlns="http://www.springframework.org/schema/beans"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">
<!-- 扫描常用的注解 @Controller @Service @Resource等 -->
<context:component-scanbase-package="com.sohu.spaces.grap"/>
<!-- 自动注入DefaultAnnotationHandlerMapping和AnnotationMethodHandlerAdapter,并提供了数据绑定支持
-->
<mvc:annotation-driven/>
<!-- view -->
<beanid="viewResolver"class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<propertyname="viewClass"value="org.springframework.web.servlet.view.JstlView"/>
<propertyname="prefix"value="/WEB-INF/page/"/>
<propertyname="suffix"value=".jsp"/>
</bean>
</beans>

五、测试例子

package com.sohu.spaces.grap.controller;

importorg.springframework.stereotype.Controller;

importorg.springframework.web.bind.annotation.RequestMapping;

/**

*<p>

* Description: 测试controller

*</p>

*@author solidwang

*@version 1.0

*@Date 2013-8-5

*/

@Controller

@RequestMapping("/start")

public class UserController {

@RequestMapping("/test")

public void test() {

System.out.println("test--------------success");

}

}

在浏览器中输入地址：http://localhost:8080/spaces-videos-grap-web/start/test.do，即可访问到该controller。
