springmvc页面提交中文乱码问题

<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> 以上可以解决post请求乱码问题。Get请求中文参数出现乱码 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"/> 另外一种方法对参数进行重新编码：
String userName newString(request.getParamter("userName").getBytes("ISO8859-1"),"utf-8")ISO8859-1是tomcat默认编码，需要将tomcat编码后的内容按utf-8编码
