关于springMVC框架的请求乱码问题

一.解决post请求乱码

<!--web.xml配置post请求乱码问题  -->
<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>

二.解决get请求的乱码问题

对于get请求的乱码问题有两种解决方案
1.修改tomcat配置文件添加编码与工程编码一致,如下:
	<Connector URIEncoding="utf-8" connectionTimeout="20000" port="8080" protocol="HTTP/1.1" redirectPort="8443"/>
2.另外一种方法对参数进行重新编码:ISO8859-1是tomcat默认编码,需要将tomcat编码后的内容按utf-8编码
String userName =  new String(request.getParamter("userName").getBytes("ISO8859-1"),"utf-8");
