spring mvc @ResponseBody返回中文乱码解决

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<span style="white-space:pre"> </span><!-- 避免返回中文时出现乱码 --><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>

<span style="white-space:pre">	</span><bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter"><span style="white-space:pre">		</span><property name="messageConverters"><span style="white-space:pre">			</span><list><span style="white-space:pre">				</span><ref bean="stringHttpMessageConverter"/><span style="white-space:pre">				</span><ref bean="mappingJackson2HttpMessageConverter"/><span style="white-space:pre">				</span><ref bean="marshallingHttpMessageConverter"/><span style="white-space:pre">			</span></list><span style="white-space:pre">		</span></property><span style="white-space:pre">	</span></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

 methodscalled 

RequestMappingHandlerMapping

 and 

RequestMappingHandlerAdapter

，Prior to Spring 3.1, type and method-level request mappings were examined in two separate stages — a controller was selected firstby the

DefaultAnnotationHandlerMapping

 andthe actual method to invoke was narrowed down second by the 

AnnotationMethodHandlerAdapter

.
