通过使用webflux在SpringBoot中扩展反应性存储库来保存实体时出错

Question

1. 这是我的文档POJO

   @Document（collection =“ users”） 公共类Employee实现Serializable {

   @Id
   private UUID id;
   
   private String firstName;
   
   private String lastName;
   
   private String email;
   
   
   public UUID getId() {
       return id;
   }
   
   public void setId(UUID id) {
       this.id = id;
   }
   
   public String getFirstName() {
       return firstName;
   }
   
   public void setFirstName(String firstName) {
       this.firstName = firstName;
   }
   
   public String getLastName() {
       return lastName;
   }
   
   public void setLastName(String lastName) {
       this.lastName = lastName;
   }
   
   public String getEmail() {
       return email;
   }
   
   public void setEmail(String email) {
       this.email = email;
   }
   
   @Override
   public boolean equals(Object o) {
       if (this == o) return true;
       if (!(o instanceof Employee)) return false;
   
       Employee employee = (Employee) o;
   
       if (!getId().equals(employee.getId())) return false;
       if (getFirstName() != null ? !getFirstName().equals(employee.getFirstName()) : employee.getFirstName() != null)
           return false;
       if (getLastName() != null ? !getLastName().equals(employee.getLastName()) : employee.getLastName() != null)
           return false;
       return getEmail().equals(employee.getEmail());
   }
   
   @Override
   public int hashCode() {
       int result = getId().hashCode();
       result = 31 * result + (getFirstName() != null ? getFirstName().hashCode() : 0);
       result = 31 * result + (getLastName() != null ? getLastName().hashCode() : 0);
       result = 31 * result + getEmail().hashCode();
       return result;
   }
   

   }

2. 这是我的存储库界面

   @Repository
   public interface EmployeeRepository extends 
            ReactiveMongoRepository<Employee, UUID> {
   
        }
   

3。这是我的服务员

@Component
public class EmployeeHandler {

    @Autowired
    private EmployeeRepository employeeRepository;

    public Mono<ServerResponse> createNewEmployee(ServerRequest request) {
        Mono<Employee> employeeMono = request.bodyToMono(Employee.class);
        Mono<Employee> newEmployee = employeeRepository.save(employeeMono);
        return ServerResponse.ok()
                .contentType(MediaType.APPLICATION_JSON)
                .build(newEmployee);
    }
}

编译错误，我在行“类型参数'S'的推断类型'S'不在其范围内；应扩展'com.kj.webfluxcruddemo.entity.Employee'”

Mono<Employee> newEmployee = employeeRepository.save(employeeMono);
