spring對亂碼的處理及其springmvc核心器註冊

1、註冊spring提供的針對POST請求的中文亂碼問題

<!-- 註冊spring提供的針對POST請求的中文亂碼問題 -->
	<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>	

2、註冊springmvc核心控制器

<!-- 註冊springmvc核心控制器 -->
	<servlet>
		<servlet-name>DispatcherServlet</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<!-- 通知DispatcherServlet去指定的目錄下加載springmvc.xml配置文件 -->
		<init-param>
			<param-name>contextConfigLocation</param-name>
			<param-value>classpath:springmvc.xml</param-value>
		</init-param>
	</servlet>
	<servlet-mapping>
		<servlet-name>DispatcherServlet</servlet-name>
		<url-pattern>*.action</url-pattern>
	</servlet-mapping>

2.1、springmvc默認配置文件的註冊方式

<span style="white-space:pre">	</span><servlet>
		<servlet-name>DispatcherServlet</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
	</servlet>
	<servlet-mapping>
		<servlet-name>DispatcherServlet</servlet-name>
		<url-pattern>*.action</url-pattern>
	</servlet-mapping>
