springMVC中遇到乱码问题

配置Post请求乱码

<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>   

对get请求解决中文乱码

1.修改tomcat配置文件添加编码与工程编码一致

<connector URLEncoding="utf-8" connectionTimeout="20000" port="8080" protocol="HTTP/1.1" redirectPort="8443"/>

1. 对参数进行重新编码

String userName new String(request.getParamter("userName").getBytes("ISO8859-1"),"utf-8")
