SpringMVC解决请求乱码

一：解决表单post请求汉字乱码问题

配置在web.xml的web-app标签内，即最外层的标签

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns="http://xmlns.jcp.org/xml/ns/javaee"
	xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
	id="WebApp_ID" version="3.1">
	
<filter>
	<filter-name>encodingFilter</filter-name>
	
	<!-- CharacterEncodingFilter的限定类名 -->
	<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
	
	<!-- 下面两个参数对应着CharacterEncodingFilter的属性的赋值  -->
	<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>

<!--  拦截器的映射，即生效的匹配路径 --->
<filter-mapping>
	<filter-name>encodingFilter</filter-name>
	<url-pattern>/*</url-pattern>
</filter-mapping>

...

</web-app>

二：get请求汉字乱码问题
