处理springMvc中responsebody返回中文乱码

法一：

  @RequestMapping(value="/getUsersByPage",produces = "application/json; charset=utf-8") @ResponseBody public String getUsers 

法二：在spring-mvc.xml中配置

     <mvc:annotation-driven>
         <mvc:message-converters>
             <bean class="org.springframework.http.converter.StringHttpMessageConverter">
                 <property name="supportedMediaTypes">
                     <list>
                         <value>application/json;charset=UTF-8</value>
                     </list>
                 </property>
             </bean>
         </mvc:message-converters>
     </mvc:annotation-driven>
