Get Ticket Endpoint

In this lesson we'll implement the get ticket endpoint.

Implementing the Get Ticket Endpoint

The get ticket endpoint allows users to retrieve detailed information about a specific ticket they have purchased.

Let's add this new endpoint to our TicketController class:

@GetMapping(path = "/{ticketId}")
public ResponseEntity<GetTicketResponseDto> getTicket(
    @AuthenticationPrincipal Jwt jwt,
    @PathVariable UUID ticketId
) {
    return ticketService
        .getTicketForUser(parseUserId(jwt), ticketId)
        .map(ticketMapper::toGetTicketResponseDto)
        .map(ResponseEntity::ok)
        .orElse(ResponseEntity.notFound().build());
}

The endpoint follows these steps:

Gets the authenticated user's ID from the JWT token
Uses the TicketService to find the ticket for that user
Maps the ticket to a DTO if found
Returns HTTP 200 with the ticket data if found, or HTTP 404 if not found
