<!--?啟動SpringMVC的注解功能，完成請求和注解POJO的映射，支持@ResponseBody注解?--> <bean?class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"> <property?name="messageConverters"> <list> <!--?JSON轉(zhuǎn)換器?--> <ref?bean="mappingJacksonHttpMessageConverter"?/> </list> </property> </bean>這段代碼提示org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter被廢棄了，所以想問問，基于servlet3.1的springmvc如何啟用注解功能呢
