After deploying war file in Tomcat api not working

Question

I'm trying to deploy app in my local tomcat but have some problems. I use: Tomcat 9, Spring boot, ReactJS and Webpack. When I run embedded Tomcat (in Eclipse) all be ok - API working good, but when I build war file and paste it to my local Tomcat - API not working, all request failed.

How I build war file:

run mvn "clean install";
paste war file to my local Tomcat directory "webapps";
wait for deploying;
go to "http://localhost:8080/web_importer/#/importCandidates". But in this moment when i run in Eclipse my app i use another path: "http://localhost:8080/#/importCandidates" and API use this path to (example) "http://localhost:8080/api/originator", not "http://localhost:8080/web_importer/api/originator".

How I can change this path?

application.properties:

server.port = 8080
management.server.port: 8995
management.server.address: 127.0.0.1
spring.servlet.multipart.max-file-size=100MB
spring.servlet.multipart.max-request-size=100MB
spring.http.encoding.force=true

OriginatorController.java:

@RequestMapping(value = "/api/originator", method = RequestMethod.GET)
public List<OriginatorModel> retrieveOriginators() {
    logger.info("Performing /api/originator GET request");
    return originatorService.retrieveOriginators();
}

The answer be can probably found in pieces of your application (source code + config) not provided in your question. Please edit your question to include a [mcve] — Selaron, Jan 22 '19 at 12:38
@Selaron, added everything that supposedly can help. If you call what else specifically needs to be added - I will add. — Se Br, Jan 22 '19 at 12:46

When you start the application from Eclipse, it uses a standalone server, which is directly accessed via localhost and the URL is http://localhost:8080/api/originator.

When you run your local tomcat instance, http://localhost:8080 is the base tomcat URL. What follows next is the name of your application, in this case web_importer. So the URL becomes http://localhost:8080/web_importer/api/originator and this is why you get 404 Not Found.

It seems that your frontend is calling the API directly at http://localhost:8080/api/originator. You need to change your base API URL in your frontend configuration when you want to use the tomcat-deployed version of your API.

This is not working for me; I have login API http://localhost:8080/api/login that works fine, but after deployment of the app to tomcat with the name of nmt, the API http://localhost:8080/nmt/api/login and http://localhost:8080/api/login are not working. it gives 404 errors. is not available. what can be wrong? — Sayed Hussainullah Sadat, Dec 13 '22 at 08:59
