What does the parameter in @RestController("/path/..") do?
Does it not set the base path like @RequestMapping("/path/..").
What is the difference?
@RestController("base-path")
回答1:
In case of @RestController the parameter value depicts the component name or bean name, whereas in @RequestMapping the value parameter is used to specify the path. Both are used for different purpose.
If you want to specify request URI path on controller class name use @RequestMapping annotation with @RestController. Something like this:
@RequestMapping("/my-path")
@RestController
class MyController {
...
}

Taken from the Spring Documentation:
@RestController-
is known as a stereotype annotation. It provides hints for people reading the code, and for Spring, that the class plays a specific role. ... so Spring will consider it when handling incoming web requests.
@RequestMapping-
annotation provides “routing” information. It is telling Spring that any HTTP request with the path “/” should be mapped to the home method. The @RestController annotation tells Spring to render the resulting string directly back to the caller.
