springMVC的乱码问题

关于get请求，tomcat8.0以上默认解决，8.0以下

在server.xml  http请求处添加 URIEncoding="UTF-8"

字符编码的filter应该在其他filter上面，否则可能会因为执行先手问题导致仍然乱码

post请求乱码需要在web.xml配置如下filter

<!-- 字符编码的filter -->
	<filter>
		<filter-name>CharacterEncodingFilter</filter-name>
		<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<!-- 		解决POST请求乱码 -->
		<init-param>
				<param-name>encoding</param-name>
				<param-value>UTF-8</param-value>
		</init-param>
		<init-param>
<!-- 		解决响应乱码 -->
				<param-name>forceEncoding</param-name>
				<param-value>true</param-value>
		</init-param>
	</filter>
	<filter-mapping>
		<filter-name>CharacterEncodingFilter</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>
