Spring MVC Json 乱码问题

1. applicationContext.xml 的配置

<!-- 基于Annotation的映射方式 --><mvc:annotation-driven > <mvc:message-converters register-defaults="true">    <bean class="org.springframework.http.converter.StringHttpMessageConverter">                <constructor-arg value="UTF-8" />            </bean>            <bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">                 <property name="supportedMediaTypes">            <list>                <value>text/html;charset=UTF-8</value>            </list>        </property>            </bean>        </mvc:message-converters></mvc:annotation-driven>

2.        Controller 的配置

@RequestMapping(value="/test",produces="text/plain;charset=UTF-8") 

@ResponseBody
