Scenario Description : When developing a project, due to internal conventions, the version and project must be indicated on the interface path, assuming that the version takes V1, Project: RMS, then all interface paths in the project are designed: http|https://ip:port| domain name/v1/ rms/*;
Because there are/v1/rms common parts of the path, I put it in a class that uses the annotation @restcontroller callout to indicate that it is a controller class, annotated with the annotation @requestmapping ("/v1/rms"). Then all the paths to the Controller class that inherit the class are prefixed with "/v1/rms" as the path.
1 Import org.springframework.web.bind.annotation.RequestMapping; 2 Import Org.springframework.web.bind.annotation.RestController; 3 4 5 @RestController 6 @RequestMapping ("/v1/rms")7publicclass Rmsbasecontroller {89 }At the same time design another class inheriting it, the class inherits from the Rmsbasecontroller class, named TestController, assuming that all the interfaces defined in the class are prefixed with "/test", Naturally, Would have thought of annotating the class with @restcontroller @RequestMapping ("/test") just like the previous base class, but after doing so, the discovery program can start, but with "http://ip:port/v1/rms/test/*" access This class of interface will be reported 404 error, and can only use "http://ip:port/test/*" to access.

Modification Method :
Remove the TestController class annotation @requestmapping ("/test") and prefix "@requestmapping" with the value of/test for each of the TestController interfaces. Corrected code:
Import Org.springframework.web.bind.annotation.requestmapping;import Org.springframework.web.bind.annotation.requestmethod;import Org.springframework.web.bind.annotation.restcontroller;import javax.servlet.http.httpservletresponse;@ Restcontrollerpublic class TestController extends Rmsbasecontroller { /** * Add Test Interface Ping * */ @ Requestmapping (value = "/test/ping", method = requestmethod.get) public final void Checkapplication ( HttpServletResponse response) { response.setstatus ($); }}Test Example: http://localhost:8090/v1/rms/test/ping
Result: Return status code: 200
Visible @RequestMapping ("/test") cannot annotate two classes that have an inheritance relationship at the same time.
Record the pits that have been trampled so that they can be bypassed later.
Spring @RequestMapping path cannot be inherited
