I am currently working through a Spring tutorial on REST (whole tutorial is at spring.io/guides/tutorials/rest/). I am pretty sure I have followed the guide accurately. I have the following code for the EmployeeController:

package com.example.buildingrest; import java.util.List; import org.springframework.web.bind.annotation.DeleteMapping; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.PathVariable; import org.springframework.web.bind.annotation.PostMapping; import org.springframework.web.bind.annotation.PutMapping; import org.springframework.web.bind.annotation.RequestBody; import org.springframework.web.bind.annotation.RestController; @RestController class EmployeeController { private final EmployeeRepository repository; EmployeeController(EmployeeRepository repository) { this.repository = repository; } // Aggregate root @GetMapping("/employees") List<Employee> all() { return repository.findAll(); } @PostMapping("/employees") Employee newEmployee(@RequestBody Employee newEmployee) { return repository.save(newEmployee); } // Single item @GetMapping("/employees/{id}") Employee one(@PathVariable Long id) { return repository.findById(id) .orElseThrow(() -> new EmployeeNotFoundException(id)); } @PutMapping("/employees/{id}") Employee replaceEmployee(@RequestBody Employee newEmployee, @PathVariable Long id) { return repository.findById(id) .map(employee -> { employee.setName(newEmployee.getName()); employee.setRole(newEmployee.getRole()); return repository.save(employee); }) .orElseGet(() -> { newEmployee.setId(id); return repository.save(newEmployee); }); } @DeleteMapping("/employees/{id}") void deleteEmployee(@PathVariable Long id) { repository.deleteById(id); } } 

When I do a CURL command to get all employees I am successful, and when I do a CURL command to get one employee by id, I am successful. The problem is when I try to POST a new employee. I am using the following command, which comes from the tutorial:

curl -X POST localhost:8080/employees -H 'Content-type:application/json' -d '{"name": "Samwise Gamgee", "role": "gardener"}' 

I get the following error:

{"timestamp":"2020-03-20T13:28:56.244+0000","status":415,"error":"Unsupported Media Type","message":"Content type 'application/x-www-form-urlencoded;charset=UTF-8' not 

supported","path":"/employees"}curl: (6) Could not resolve host: Samwise Gamgee, curl: (6) Could not resolve host: role curl: (3) [globbing] unmatched close brace/bracket in column 9

As far as the unmatched close brace/bracket, I have looked at the code and the CURL command up and down and cannot find it. As far as the Unsupported Media Type, I don't understand why it is stating x-www-form-urlencoded when I have been using JSON for the whole application. And I have copied the curl command straight from the tutorial.

Any ideas what is wrong?
