try to change this: Show
with this: @RequestMapping(value = "insacol/static/api/users", method = RequestMethod.POST) public void insertUser(@RequestBody User user){ userDao.insertar(user); }The problem should be related to the URL you invoke; The issue is with the baseUrl, you need to use = (used for initialization) instead of : (used in typescript to define an objects type). Since you are never really initializing the variable with proper url, request is going to some random url like http://localhost:4200/undefined causing 404. You can update the url as follows and try: private baseUrl = "http://localhost:8080/evaluationController/notes";Failed to load resource: the server responded with a status of 404.

Whitable Error page in springbootThere's a few tricky things here. Firstly, you've configured your server anycodings_spring-boot to listen on localhost:4200, which is anycodings_spring-boot fine. You've done that with this line: @CrossOrigin(origins= "http://localhost:4200")Next you've told spring this: @RequestMapping(path="user")Spring will take user and add it to anycodings_spring-boot http://localhost:4200. So it's listening anycodings_spring-boot now on http://localhost:4200user - this anycodings_spring-boot isn't what you want, try adding a / so anycodings_spring-boot that your request mapping looks like anycodings_spring-boot this: @RequestMapping(path="/user")Your application should now be listening anycodings_spring-boot on http://localhost:4200/user. Great! Next, to hit the getUsers method, you've anycodings_spring-boot defined @GetMapping("/get") which, anycodings_spring-boot combined with your other annotations anycodings_spring-boot will mean that to hit getUsers you need anycodings_spring-boot to make a GET to anycodings_spring-boot http://localhost:4200/user/get, assuming anycodings_spring-boot everything was working correctly. A little trick is that @GetMapping is anycodings_spring-boot actually an alias for anycodings_spring-boot @RequestMapping(method = anycodings_spring-boot RequestMethod.GET) - so to tidy this up anycodings_spring-boot you could delete anycodings_spring-boot @RequestMapping(path="user") and just anycodings_spring-boot use @GetMapping(value = "/users") and this anycodings_spring-boot would mean that a GET against anycodings_spring-boot http://localhost:4200/user would anycodings_spring-boot activate your getUsers method. 0 2022-08-01T03:04:05+00:00 2022-08-01T03:04:05+00:00Answer Link mRahman |
