utf-8-spring mvc json返回中文亂碼 配置後依然不好使

spring mvc json返回中文亂碼 配置後依然不好使

  <context:annotation-config />
     <context:component-scan base-package="may.web.action"></context:component-scan>


      <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
                <property name="messageConverters">
                    <list>
                         <bean class = "org.springframework.http.converter.StringHttpMessageConverter">    
                  <property name = "supportedMediaTypes">   
                        <list>    
                          <value>text/plain;charset=UTF-8</value>
                          <value>application/json;charset=UTF-8</value>    
                      </list>    
                  </property>  
                     </bean> 
                     <bean  class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter" />
                  </list>
            </property>
            <property name="webBindingInitializer">  
                <bean class="may.filter.MyBindingInitializer"/>  
            </property>
         </bean> 

     <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver" >
        <property name="viewClass"
                    value="org.springframework.web.servlet.view.JstlView" />
        <property name="prefix" value="/jsp/"></property>  
        <property name="suffix" value=".jsp"></property>  
        </bean>
    <mvc:annotation-driven/>


      </beans>

        xml已經配置了  但是還是中文亂碼  還是text/plain:charset=ISO8859-1，自己弄了一下午 但還是不好使 

最佳回答：

    <!-- mvc 返回亂碼處理 -->
    <mvc:annotation-driven>
        <mvc:message-converters register-defaults="true">
            <bean class="org.springframework.http.converter.StringHttpMessageConverter">
                <property name="supportedMediaTypes" value="text/plain;charset=UTF-8" />
            </bean>
        </mvc:message-converters>
    </mvc:annotation-driven>
