# SSM #

# **maven web项目：Xml版** #

## 一.**web项目入口（2.5版）** ##

>  *  位置：WEB-INF/web.xml 文件
>  *  开发位置：src/main/webapp/WEB-INF/web.xml

## 二.**web.xml 配置** ##

>  *  配置spring相关内容：配置监听器，加载与spring相关的配置文件（监听器由spring官方提供）

<context-param>
       <param-name>contextConfigLocation</param-name>
       <param-value>classpath:spring/applicationContext*.xml</param-value>
    </context-param>
    
    <listener>
       <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

>  *  配置spring mvc相关内容，配置servlet，用于处理所有的请求

<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/springmvc.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>

*  扩展：【了解】中文乱码过滤器配置

<filter>
       <filter-name>CharacterEncodingFilter</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>
    </filter>
    <filter-mapping>
       <filter-name>CharacterEncodingFilter</filter-name>
       <url-pattern>/*</url-pattern>
    </filter-mapping>

## 三.**Spring xml配置基本模板** ##
