Method Details

authenticateUser

@PostMapping("/signin")
public ResponseEntity<?> authenticateUser(@Valid @RequestBody
 @Valid LoginDto loginRequest)

Authenticates a user and generates a JWT token.

This endpoint processes login requests by validating the provided credentials against the stored user data. Upon successful authentication, it generates a JWT token that can be used for subsequent authorized API requests. The response includes the token, user ID, username, email, and assigned roles.

Parameters:

loginRequest - The DTO containing login credentials (username and password)

Returns:

ResponseEntity with JWT token and user information on success

registerUser

@PostMapping("/signup")
public ResponseEntity<?> registerUser(@Valid @RequestBody
 @Valid RegisterDto signUpRequest)

Registers a new user in the system.

This endpoint handles user registration by validating the request data, checking for existing username or email conflicts, and creating a new user account with the specified roles. If no role is specified, the user is assigned the default CANDIDATE role. The password is securely encoded before storage.

Parameters:

signUpRequest - The DTO containing registration details (username, email, password, roles)

Returns:

ResponseEntity with success message or error details
