SpringBoot RestApi call 404 Not Found error-CodePudding

I have a SpringBoot application that I am able to start ( http://localhost:80 ).

In my application.yml :

application:
  baseurl: /respViewer/api

In my application I defined a @RestController and an endpoint :

@RestController
@RequestMapping("${application.baseurl}/viewer")

....

@PostMapping(value = "/getRespList", consumes = MediaType.APPLICATION_JSON_VALUE,
                produces = MediaType.APPLICATION_JSON_VALUE)
        public ResponseEntity<Object> getResponsibilities(@RequestBody RequestDetail requestDetail)

When I try to access my application using Insomnia or through the Browser I am getting 404 Error.

http://localhost:8080/respViewer/api/viewer/getRespList

{
  "timestamp": "2022-04-25T19:52:32.426 00:00",
  "status": 404,
  "error": "Not Found",
  "message": "",
  "path": "/respViewer/api/viewer/getRespList"
}

I also checked console output and found these messages :

 POST "/respViewer/api/viewer/getRespList", parameters={}
2022-04-25 15:52:32.253 DEBUG 3744 --- [nio-8080-exec-1] o.s.w.s.h.SimpleUrlHandlerMapping        : Mapped to ResourceHttpRequestHandler ["classpath:/META-INF/resources/", "classpath:/resources/", "classpath:/static/", "classpath:/public/", "/"]

What am I doing wrong?

Update 1 :

I added packages location where I have a REST Controller to application.yml :

spring:
      component:
        scan:
          packages: com.example.demoRespManager

and now I am not getting 404 Error, however it doesn't look like I am getting into the body of implementation method. I setup a break-point in the first line of the method but never stop there. An output in the Console is :

UPDATE 2 :

In the Header section of the INSOMNIA application I added Content-type = application/json, since I defined it in my endpoint, and after that it started to work. I was able to start an application in the DEBUG mode and when I made a POST request in INSOMNIA I stopped at the first line of my method implementation.

CodePudding user response：

I solved this issue :

updated my properties file with the list of the packages that contain the beans, it's an equivalent of @ComponentScan in Application ( spring.component.scan.packages )
Added Content-type = application/json to the Header in the Insomnia.
