Three ways:-

1. Using RestTemplate

2. Using WebClient

3. Using Spring Cloud OpenFeign

@Service
@AllArgsConstructor
public class EmployeeServiceImpl implements EmployeeService {

    private static final Logger LOGGER = LoggerFactory.getLogger(EmployeeServiceImpl.class);

    private EmployeeRepository employeeRepository;

    private WebClient webClient;
    private APIClient apiClient;
    @Override
    public EmployeeDto saveEmployee(EmployeeDto employeeDto) {

        Employee employee = EmployeeMapper.mapToEmployee(employeeDto);

        Employee saveDEmployee = employeeRepository.save(employee);

        EmployeeDto savedEmployeeDto = EmployeeMapper.mapToEmployeeDto(saveDEmployee);

        return savedEmployeeDto;
    }

    //@CircuitBreaker(name = "${spring.application.name}", fallbackMethod = "getDefaultDepartment")
    @Retry(name = "${spring.application.name}", fallbackMethod = "getDefaultDepartment")
    @Override
    public APIResponseDto getEmployeeById(Long employeeId) {

        LOGGER.info("inside getEmployeeById() method");
        Employee employee = employeeRepository.findById(employeeId).get();
        DepartmentDto departmentDto = webClient.get()
                .uri("http://localhost:8080/api/departments/" + employee.getDepartmentCode())
                .retrieve()
                .bodyToMono(DepartmentDto.class)
                .block();
        OrganizationDto organizationDto = webClient.get()
                .uri("http://localhost:8083/api/organizations/" + employee.getOrganizationCode())
                .retrieve()
                .bodyToMono(OrganizationDto.class)
                .block();
        EmployeeDto employeeDto = EmployeeMapper.mapToEmployeeDto(employee);
        APIResponseDto apiResponseDto = new APIResponseDto();
        apiResponseDto.setEmployee(employeeDto);
        apiResponseDto.setDepartment(departmentDto);
        apiResponseDto.setOrganization(organizationDto);
        return apiResponseDto;
    }
