@RestController and @Controller in Spring Framework
The primary difference between @RestController and @Controller in the Spring Framework lies in how they handle HTTP
@Controller :
@Controller :
- @Controller is used to define a controller class that can handle HTTP requests and return views.
- Typically used in web applications where the responses are HTML pages.
- You need to use @ResponseBody on methods to indicate that the return value should be written directly to the HTTP response body.
@RestController:
- @RestController is a specialized version of @Controller that combines @Controller and @ResponseBody.
- Designed for RESTful web services where the responses are typically JSON or XML.
- All methods in a class annotated with @RestController implicitly have @ResponseBody applied, so the return values are written directly to the HTTP response body.
Summary
Use @Controller when you need to return views (HTML pages).
Use @Controller when you need to return views (HTML pages).
Use @RestController when you need to create RESTful services and return data (like JSON or XML) directly in the response body.
