I need to mapping two GET methods look like:
GET /tickets - Retrieves a list of tickets
GET /tickets/12 - Retrieves a specific ticket
But when I mapped this, the Spring got confused!
When I hit http://localhost:8080/tickets in the Chrome, the result on server is:
DefaultHandlerExceptionResolver : Resolved [org.springframework.web.method.annotation.MethodArgumentTypeMismatchException: Failed to convert value of type 'java.lang.String' to required type 'java.lang.Long'; nested exception is java.lang.NumberFormatException: For input string: "tickets"]
When I hit http://localhost:8080/tickets/12 in the Chrome, the result on server is:
QueryTranslatorFactoryInitiator : HHH000397: Using ASTQueryTranslatorFactory
My Spring controller is:
package wendelsilverio.api.ticket;
import java.util.List;
import java.util.Optional;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RestController;
@RestController("tickets")
public class TicketController {
@Autowired
private TicketRepository repository;
@GetMapping
public List<TicketEntity> getTickets() {
return repository.findAll();
}
@GetMapping("/{id}")
public Optional<TicketEntity> getTicket(@PathVariable("id") Long id) {
return repository.findById(Long.valueOf(id));
}
}
My unit test is:
package wendelsilverio.api.ticket;

mockMvc.perform(get("tickets/12").contentType(MediaType.APPLICATION_JSON)).andExpect(status().isOk())
.andExpect(jsonPath("$.id", is(12L))).andExpect(jsonPath("$.content", is("Twelve ticket")));
}
}
I'm using Java 11 and Spring Boot 2.1.6
@GetMapping("{id}")
