spring4 mvc rest返回中文乱码?

试试把下面两个配置了
web.xml

 <!-- 编码配置 -->
  <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>

tomcat的server.xml中加URIEncoding属性
<Connector URIEncoding="UTF-8" connectionTimeout="20000" port="80" protocol="HTTP/1.1" redirectPort="8443"/>
