我正在尝试编写一个简单的程序来构建工作计划，但无法正确获取数据。当我试图招募员工时
@Entity
@Data
@Builder
@AllArgsConstructor
@NoArgsConstructor
public class Employee {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
private String firstName;
private String lastName;
private Double rate;
private TypeOfContract typeOfContract;
private String specialization;
private LocalDate dateOfBirthday;
private String PESEL;
private String ZUSindex;
@OneToMany(mappedBy = "employee", fetch = FetchType.EAGER)
Set<Shift> workedShift= new HashSet<>();
public String getFullName() {
return firstName+" "+lastName;
}
public void setFullName(String firstName, String lastName) {
this.firstName = firstName;
this.lastName = lastName;
}
@Override
public String toString() {
return "Employee{" +
"id=" + id +
", firstName='" + firstName + '\'' +
", lastName='" + lastName + '\'' +
", rate=" + rate +
", typeOfContract=" + typeOfContract +
", specialization='" + specialization + '\'' +
", dateOfBirthday=" + dateOfBirthday +
", PESEL='" + PESEL + '\'' +
", ZUSindex='" + ZUSindex + '\'' +"}";
}
}
从数据库中，当我尝试获取班级班次时，现场工作班次为空
@Entity
@Data
@Builder
@AllArgsConstructor
@NoArgsConstructor
public class Shift implements Comparable<Shift>{
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
private String station;
private LocalDate date;
private String startTime;
private String endTime;
private String actualStartTime;
private String actualEndTime;
@ManyToOne
Employee employee;
public HoursClass getWorkedTime() {
if (this.actualStartTime == null || this.actualEndTime == null) {
return null;
}
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("HH:mm");
LocalTime localStartTime = LocalTime.parse(this.actualStartTime, formatter);
LocalTime localEndTime = LocalTime.parse(this.actualEndTime, formatter);
Duration duration;
if (localEndTime.isBefore(localStartTime)) {
duration = Duration.between(localStartTime, LocalTime.MAX).plus(Duration.between(LocalTime.MIN, localEndTime));
} else {
duration = Duration.between(localStartTime, localEndTime);
}
long totalMinutes = duration.toMinutes();
int hours = (int) (totalMinutes / 60);
int minutes = (int) (totalMinutes % 60);
return new HoursClass(hours, minutes);
}
@Override
public int compareTo(Shift o) {
return 0;
}
@Override
public String toString() {
return "Shift{" +
"id=" + id +
", station='" + station + '\'' +
", date=" + date +
", startTime='" + startTime + '\'' +
", endTime='" + endTime + '\'' +
", actualStartTime='" + actualStartTime + '\'' +
", actualEndTime='" + actualEndTime + '\'' +
", employee=" + employee +
'}';
}
}
从数据库中，employee 字段正确填充了数据，我尝试使用 findAll() 方法（为我们提供 JPA 接口）和使用自定义方法从数据库获取数据
public interface EmployeeRepository extends JpaRepository<Employee,Long> {
///**
//* Searching employee by id
//*
//* @param id of the searched employee
//* @return the searched employee
//*/
//@Query("select e from Employee e where e.id = :id")
//Employee getEmployeeById(Long id);
@Query("SELECT e FROM Employee e JOIN FETCH e.workedShift")
List<Employee> findAllWithShifts();
/**
* Searching employee by full name
*
* @param fullName of the searched employee
* @return the searched employee
*/
@Query("SELECT e FROM Employee e WHERE LOWER(CONCAT(e.firstName, ' ', e.lastName)) = lower(:fullName)")
Employee getEmployeeByFullName(String fullName);
/**
* Searching employee by PESEL
*
* @param pesel of the searched employee
* @return the searched employee
*/
@Query("SELECT e FROM Employee e WHERE e.PESEL = :pesel")
Employee getEmployeeByPESEL(String pesel);
}
。这实际上是我的课程，我在其中直接处理问题
@Component
@AllArgsConstructor
public class BootStrap implements CommandLineRunner {
EmployeeRepository employeeRepository;
ShiftRepository shiftRepository;
EmployeeService employeeService;
ShiftServiceImpl shiftService;
@Override
public void run(String... args){
Employee employee = Employee.builder()
.firstName("Adam")
.lastName("Kowalski")
.PESEL("03947283728")
.rate(23.5)
.build();
Employee savedEmployee = employeeRepository.save(employee);
Stream<Shift> randomShifts = Stream.generate(() -> {
return Shift.builder()
.station("Station " + (new Random().nextInt(10) + 1))
.date(LocalDate.of(2024,5,5))
.startTime("10:00")
.endTime("20:00")
.actualStartTime("10:00")
.actualEndTime("20:00")
.employee(savedEmployee)
.build();
}).limit(5);
shiftRepository.saveAll(randomShifts.collect(Collectors.toUnmodifiableSet()));
System.out.println("\n after save all\n");
System.out.println("\n All employees "+ employeeService.getAllEmployees());
System.out.println("\nsalary= "+employeeService.getMonthSalary(1L,5));
System.out.println("\ntax= "+employeeService.getMonthTax(1L,5));
System.out.println("\nRevenue= "+employeeService.getMonthRevenue(1L,5));
//employeeRepository.findAll().forEach(publisher -> System.out.println("\n"+publisher+" have "+publisher.getWorkedShift()));
employeeRepository.findAll().forEach(publisher -> System.out.println("\n"+publisher+" have "+publisher.getWorkedShift()));
shiftRepository.findAll().forEach(book -> System.out.println("\n"+book+ " have "+book.getEmployee()));
System.out.println();
System.out.println("\n all shift by employee 1"+shiftService.getAllShiftByEmployee(1L));
System.out.println();
System.out.println("\n employee with pesel"+employeeService.getEmployeeByPESEL("03947283728"));
}
}
这里我将数据保存到数据库，然后实际检索它，当我通过控制器操作数据时，我也观察到了问题。 这就是数据库填充数据后的样子
[shift table](https://i.sstatic.net/26KW7O4M.png)
[employee table](https://i.sstatic.net/mhdSRqDs.png)
，这是运行类后控制台直接显示的日志

我使用h2数据库
我尝试更改向数据库添加对象的顺序，我检查了两个代码（工作和不工作），以不同的方式检索对象，删除并添加了实体类的注释
我希望当从数据库接收员工时，工作班次字段将填充适当的值
都是关于注解@Data的，当我删除它时，问题就消失了
