解决中文乱码问题

post中文乱码:

在web.xml中加入:

<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>

对于get请求中文参数出现乱码解决方法有两个:

  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:

  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
