如题所述
4.0重要新改进@RestController注解继承自@Controller注解4.0前版本Spring MVC组件都使用@Controller标识前类控制器servlet
使用特性我发REST服务候需要使用@Controller专门@RestController
实现RESTful web services候response直通response body发送简化发Spring 4.0提供专门版本controller面我看看@RestController实现定义：
@Target(value=TYPE)
@Retention(value=RUNTIME)
@Documented
@Controller
@ResponseBody
public @interface RestController
官解释：
A convenience annotation that is itself annotated with @Controller and @ResponseBody. Types that carry this annotation are treated as controllers where @RequestMapping methods assume @ResponseBody semantics by default.
注解本身使用@Controller@ResponseBody注解使用注解类看作controller-使用@RequestMapping默认@ResponseBody注解
@ResponseBody – As of version 4.0 this annotation can also be added on the type level in which case is inherited and does not need to be added on the method level.
@ResponseBody加类级通继承级需要添加
