sping mvc中添加@ResponseBody，返回中文字符串时出现乱码，且在applicationContext-web.xml中已经配置StringHttpMessageConverter

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

但是出现乱码，原因是因为将<mvc:annotation-driven/>配置放在了RequestMappingHandlerAdapter配置的前边了，导致后边配置的StringHttpMessageConverter配置无效，解决办法，因为<mvc:annotation-driven/>默认也会加载RequestMappingHandlerAdapter，所以需要把<mvc:annotation-driver/>放置到RequestMappingHandlerAdapter配置的后边，中文乱码的问题解决。

注：spring MVC 3.1之后，`@RequestMapping` methods called `RequestMappingHandlerMapping` and `RequestMappingHandlerAdapter`

，Prior to Spring 3.1, type and method-level request mappings were examined in two separate stages — a controller was selected first by the`DefaultAnnotationHandlerMapping` and the actual method to invoke was narrowed down second by the `AnnotationMethodHandlerAdapter`.
