在web.xml添加post乱码处理的过虑器。
<!-- post乱码处理过虑器 -->
<filter>
<filter-name>CharacterEncodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>

对于get乱码:
方法1:
修改tomcat /conf/server.xml
<Connector URIEncoding="utf-8" connectionTimeout="20000" port="8080" protocol="HTTP/1.1" redirectPort="8443"/>
方法2:
手动重新编码
String userName new
String(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
