SpringMVC解决POST和GET请求中文乱码问题

POST请求中文乱码问题：

使用CharacterEncodingFilter这个过滤器

在xml文件里配置encoding为utf-8即可

<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>
    <init-param>
      <param-name>forceEncoding</param-name>
      <param-value>true</param-value>
    </init-param>
  </filter>
  <filter-mapping>
    <filter-name>CharacterEncodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>

GET请求中文乱码问题：

修改tomcat的server.xml，在Connector标签后面+ URIEncoding="utf-8"
