Spring Cloud OpenFeign is a declarative web service client.

It makes writing web service clients easier. To use Feign create an interface and annotate it. It has pluggable annotation support including Feign annotations and JAX-RS annotations.

@RestController
class EmployeeController {

  private final EmployeeRepository repository;

  EmployeeController(EmployeeRepository repository) {
    this.repository = repository;
  }

  @GetMapping("/employees")
  List<Employee> all() {
    return repository.findAll();
  }

  @PostMapping("/employees")
  Employee newEmployee(@RequestBody Employee newEmployee) {
    return repository.save(newEmployee);
  }

  @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);
  }
}
