Springboot Restapi致电404找不到错误
我有一个可以启动的Springboot应用程序(http:// localhost:80)。
在我的application.yml中:
application:
baseurl: /respViewer/api
在我的应用程序中,我定义了一个@RestController和一个端点:
@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)
当我尝试使用失眠症或通过浏览器访问应用程序时,我会遇到404错误。
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"
}
我还检查了控制台输出并找到了这些消息:
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/", "/"]
2022-04-25 15:52:32.382 DEBUG 3744 --- [nio-8080-exec-1] o.s.w.s.r.ResourceHttpRequestHandler : Resource not found
2022-04-25 15:52:32.387 DEBUG 3744 --- [nio-8080-exec-1] o.s.w.s.DispatcherServlet : Completed 404 NOT_FOUND
我在做什么错?
更新1:
添加了包含REST控制器的软件包位置。
spring:
component:
scan:
packages: com.example.demoRespManager
我 我在方法的第一行中设置了一个断点,但永远不会停止。控制台中的输出是:

更新2:
在失眠应用程序的“标头”部分中,我添加了content-type = application/json,因为我在端点中定义了它,之后它开始工作。我能够在调试模式下启动一个应用程序,当我在失眠症中提出帖子请求时,我在方法实现的第一行停止了。
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/", "/"]

2022-04-25 15:52:32.387 DEBUG 3744 --- [nio-8080-exec-1] o.s.w.s.DispatcherServlet : Completed 404 NOT_FOUND
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 :
2022-04-25 21:25:43.749 INFO 27996 --- [nio-8080-exec-1] o.s.w.s.DispatcherServlet : Initializing Servlet 'dispatcherServlet'

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.
