正常会在web.xml文件中配置

<filter>    <filter-name>Set Character Encoding</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>Set Character Encoding</filter-name>    <url-pattern>/*</url-pattern>  </filter-mapping>

但是经常会发现POST、GET请求中有中文，收到的结果是乱码。
原因：Servlet容器（TOmcat等）采用的不是UTF-8编码。
解决方法：在Tomcat的servlet.xml中设置URIEncoding=”UTF-8”

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