@OneToMany和@ManyToOne使用JPA hibernate实现无限递归

@Entity
public class Department {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    @OneToMany(mappedBy = "department", cascade = CascadeType.ALL, fetch = FetchType.LAZY)
    private List<Employee> employees;
}

@Entity
public class Employee {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    @ManyToOne
    @JoinColumn(name = "department_id")
    private Department department;
}

@Entity
public class Department {
    // ...

    @JsonIgnore
    @OneToMany(mappedBy = "department", cascade = CascadeType.ALL, fetch = FetchType.LAZY)
    private List<Employee> employees;
}

public class DepartmentDTO {
    private Long id;
    private String name;
    // 其他需要的字段

    // getter 和 setter 方法
}

@OneToMany(mappedBy = "department", cascade = CascadeType.ALL, fetch = FetchType.LAZY)
private List<Employee> employees;

@Entity
public class Department {
    // ...

    @JsonManagedReference
    @OneToMany(mappedBy = "department", cascade = CascadeType.ALL, fetch = FetchType.LAZY)
    private List<Employee> employees;
}

@Entity
public class Employee {
    // ...

    @JsonBackReference
    @ManyToOne
    @JoinColumn(name = "department_id")
    private Department department;
}
