springmvc返回json乱码

注解方式：@RequestMapping(value="/路径",method = RequestMethod.GET,produces= MediaType.APPLICATION_JSON_VALUE+";charset=utf-8")

springmvc配置：

<!-- 处理请求返回json字符串的乱码问题 -->
<MVC:annotation-driven>
    <MVC:message-converters register-defaults="true">
        <bean class="org.springframework.http.converter.StringHttpMessageConverter">
            <property name="supportedMediaTypes">
                <list>
                    <value>text/html;charset=UTF-8</value>
                    <value>application/json;charset=UTF-8</value>
                </list>
            </property>
        </bean>
    </MVC:message-converters>
</MVC:annotation-driven>

<!--定义扫描的包-->
<context:component-scan base-package="com.whz.controller01"></context:component-scan>
