我在Employee实体和Task实体之间有一个关系，但是当我在仓库中插入数据时，或者当我在Postman中获取数据时，它没有出现，我认为问题在于关系。
它们之间的关系是：一个员工至少有一个任务。
这是员工实体：

@Entity
@Data
public class Employee {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Integer id;

    @NotEmpty(message = "Please enter the employee name!")
    private String employeeName;

    private Integer employeeNumber;

    @Embedded
    private Address address;

    @ManyToMany
    @JoinTable(
            name = "task_employee",
            joinColumns = @JoinColumn(name = "employee_id"),
            inverseJoinColumns = @JoinColumn(name = "task_id")
    )
    private List<Task> tasks;

    public Employee(String employeeName, Integer employeeNumber, Address address) {
        this.employeeName = employeeName;
        this.employeeNumber = employeeNumber;
        this.address = address;

    }

    public Employee() {
    }

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getEmployeeName() {
        return employeeName;
    }

    public void setEmployeeName(String employeeName) {
        this.employeeName = employeeName;
    }

    public Integer getEmployeeNumber() {
        return employeeNumber;
    }

    public void setEmployeeNumber(Integer employeeNumber) {
        this.employeeNumber = employeeNumber;
    }

    public Address getAddress() {
        return address;
    }

    public void setAddress(Address address) {
        this.address = address;
    }

    public List<Task> getTasks() {
        return tasks;
    }

    public void setTasks(List<Task> tasks) {
        this.tasks = tasks;
    }
}

字符串

任务实体：

@Entity
public class Task {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Integer taskId;

    @NotEmpty(message = " Please Enter the Task name!")
    private String name;

    @ManyToMany(mappedBy = "tasks")
    private List<Employee> employees;

    public Task() {
    }
    public Task(String name) {
        this.name = name;
        employees = new ArrayList<>();
    }
    public Integer getTaskId() {
        return taskId;
    }
    public void setTaskId(Integer taskId) {
        this.taskId = taskId;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public List<Employee> getEmployees() {
        return employees;
    }
    public void setEmployees(List<Employee> employees) {
        this.employees = employees;
    }
}

这是我在Postman中发送GET Employee时出现的内容：

{
    "id": 3,
    "employeeName": "fahad",
    "employeeNumber": 23,
    "address": {
        "street": "salah",
        "city": "Jeddah",
        "state": "makkah",
        "postalCode": "m1"
    },
    "tasks": []
}
