springmvc 返回汉字乱码

1、删除配置文件中的<mvc:annotation-driven  />

2、添加如下配置

 <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
        <property name="cacheSeconds" value="0" />
        <property name="messageConverters">
             <list>
                 <bean class = "org.springframework.http.converter.StringHttpMessageConverter">
                    <property name = "supportedMediaTypes">
                          <list>
                              <value>text/html;charset=UTF-8</value>
                         </list>
                    </property>
                 </bean>
            </list>
        </property>
    </bean>
