get post 中文请求乱码解决方式

一 get请求乱码

在tomcat中的conf下的server.xml添加  URIEncoding="UTF-8"

   <Connector  URIEncoding="UTF-8" port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />

二post请求

在web.xml加编码过滤器

<filter>
  <filter-name>characterEncoding</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>characterEncoding</filter-name>
  <url-pattern>/*</url-pattern>
  </filter-mapping>
