在springmvc里發(fā)送ajax出現(xiàn)中文亂碼應(yīng)該如何處理

@RequestMapping(value = "/configrole", method = RequestMethod.GET, produces = "text/html;charset=UTF-8") 
public @ResponseBody String configrole() { 
 ...... 
}

public class StringHttpMessageConverter extends AbstractHttpMessageConverter<String> 
{ 
 public static final Charset DEFAULT_CHARSET = Charset.forName("UTF-8"); 
 .......... 
}

public MediaType(String type, String subtype, Charset charset) { 
 super(type, subtype, charset); 
}

<bean id="stringHttpMessageConverter" 
 class="org.springframework.http.converter.StringHttpMessageConverter"> 
 <property name="supportedMediaTypes"> 
 <list> 
 <bean class="org.springframework.http.MediaType"> 
 <constructor-arg value="text" /> 
 <constructor-arg value="plain" /> 
 <constructor-arg value="UTF-8" /> 
 </bean> 
 </list> 
 </property> 
</bean>

<mvc:annotation-driven>
