spring @Controller 和 @RestController 注解的区别 [英] Difference between spring @Controller and @RestController annotation

问题描述

spring @Controller 和 @RestController 注解的区别.

Difference between spring @Controller and @RestController annotation.

@Controller 注释是否可以同时用于 Web MVC 和 REST 应用程序?
如果是，如何区分是Web MVC还是REST应用.

Can @Controller annotation be used for both Web MVC and REST applications?
If yes, how can we differentiate if it is Web MVC or REST application.

推荐答案

• @Controller 用于将类标记为 Spring MVC 控制器.
• @RestController 是一个方便的注解，只不过是添加了 @Controller 和 @ResponseBody 注释(参见:Javadoc)
• @Controller is used to mark classes as Spring MVC Controller.
• @RestController is a convenience annotation that does nothing more than adding the @Controller and @ResponseBody annotations (see: Javadoc)

所以下面的两个控制器定义应该是一样的

So the following two controller definitions should do the same

@Controller
@ResponseBody
public class MyController { }

@RestController
public class MyRestController { }
