Java spring - Posting a simple form not working

I am new to Java and Spring and I am trying to create a simple POST form. Template looks like this:

<form action="#" th:action="@{/notes}" method="POST">
  <input type="hidden" name="noteId" id="note-id">
  <div class="form-group">
    <label for="note-title" class="col-form-label">Title</label>
    <input type="text" name= "noteTitle" class="form-control" id="note-title" maxlength="20" required>
  </div>
  <div class="form-group">
    <label for="note-description" class="col-form-label">Description</label>
    <textarea class="form-control" name="noteDescription" id="note-description" rows="5" maxlength="1000" required></textarea>
  </div>
  <button id="noteSubmit" type="submit" class="d-none"></button>
</form>

And this is the controller for this POST endpoint:

@PostMapping("/notes")
    public String postNote(@ModelAttribute Note note, Authentication authentication, Model model) throws IOException {
        User user = this.userService.getUser(authentication.getName());
        Integer userid = user.getUserId();
        noteService.createNote(note, userid);
        model.addAttribute("success",true);
        model.addAttribute("message","New note added successfully!");
        return "result";
    }

The noteService createNote method looks like this:

public int createNote(Note note, Integer userid) {
    return noteMapper.insert(new Note(null, note.getNotetitle(), note.getNotedescription(), userid));
}

And the mapper looks like this:

@Insert("INSERT INTO CREDENTIALS (notetitle, notedescription, userid) VALUES(#{filename}, #{notetitle}, #{notedescription}, #{userid})")
@Options(useGeneratedKeys = true, keyProperty = "noteid")
int insert(Note note);

This is the model:

public class Note {
    private Integer noteid;
    private String notetitle;
    private String notedescription;
    private Integer userid;

    public Note(Integer noteid, String notetitle, String notedescription, Integer userid) {
        this.noteid = noteid;
        this.notetitle = notetitle;
        this.notedescription = notedescription;
        this.userid = userid;
    }

    public Integer getNoteid() {
        return noteid;
    }

    public void setNoteid(Integer fileId) {
        this.noteid = noteid;
    }

    public String getNotetitle() {
        return notetitle;
    }

    public void setNotetitle(String filename) {
        this.notetitle = notetitle;
    }

    public String getNotedescription() {
        return notedescription;
    }

    public void setNotedescription(String notedescription) {
        this.notedescription = notedescription;
    }

    public Integer getUserid() {
        return userid;
    }

    public void setUserid(Integer userid) { this.userid = userid; }
}

And this is the sql schema:

CREATE TABLE IF NOT EXISTS NOTES (
    noteid INT PRIMARY KEY auto_increment,
    notetitle VARCHAR(20),
    notedescription VARCHAR (1000),
    userid INT,
    foreign key (userid) references USERS(userid)
);

When I try to post a note I get an error:

There was an unexpected error (type=Not Found, status=404). No message available

When I run it in debug mode it doesn't even get to the controller. What am I doing wrong here? This is the repo.

Then the API wasn't even exposed.

If you run the project you should get the list of exposed APIs in the log. Such as

DEBUG 9736 --- [ main] s.w.s.m.m.a.RequestMappingHandlerMapping : 19 mappings in 'requestMappingHandlerMapping'

If you use Spring Boot Actuator on intellij: you can check list of API in Endpoints tab, it can be really helpful: enter image description here

As @Leff figured out himself by now, he was simply missing

@RestController
public class NoteController {

...above his NoteController Class.

@RestController tells Spring that the underlying class is a Rest-Endpoint Bean.

@Restcontroller inherits from @Controller, see Spring Boot Doc:

The first annotation on our Example class is @RestController. This is known as a stereotype annotation. It provides hints for people reading the code and for Spring that the class plays a specific role. In this case, our class is a web @Controller, so Spring considers it when handling incoming web requests.

The @RequestMapping annotation provides “routing” information. It tells Spring that any HTTP request with the / path should be mapped to the home method. The @RestController annotation tells Spring to render the resulting string directly back to the caller.

Error 404 usually means you have wrong url. (https://httpstatuses.com/404)

That explains why " it doesn't even get to the controller."

Double check that you are pointing to the right API url
