如何解决POST请求中文乱码问题,GET的又如何处理呢?

在web.xml中加入:

  1. <filter>
  2.     <filter-name>CharacterEncodingFilter</filter-name>
  3.     <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
  4. <init-param>
  5.         <param-name>encoding</param-name>
  6.         <param-value>utf-8</param-value>
  7.     </init-param>
  8. </filter>
  9. <filter-mapping>
  10.     <filter-name>CharacterEncodingFilter</filter-name>
  11.     <url-pattern>/*</url-pattern>
  12. </filter-mapping>
以上可以解决post请求乱码问题。对于get请求中文参数出现乱码解决方法有两个:

修改tomcat配置文件添加编码与工程编码一致,如下:

  1. <ConnectorURIEncoding="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:

  1. 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
