Question

我遇到了将实体转换为JSON的问题。此Object与其他实体具有@ManyToMany关系，并且没有注释正在工作（@ JsonManagedReferenced / @ JsonBackReference，@ JsonIgnore，@ JsonIgnoreProperties，@ JsonIdentityInfo）。这些适用于其他实体中的其他关系（但不是很多）。

我的第一个实体：

    @Entity
    @JsonIdentityInfo(generator = ObjectIdGenerators.PropertyGenerator.class, property = "id")
    public class Intervention implements Serializable {

    @Id
    private Integer id;
    @ManyToMany(cascade = CascadeType.ALL, mappedBy = "interventionList")
    private List<Employee> employeeList = new ArrayList<>();

    public Intervention() {
        }

// getters and setters 
}

我的第二个：

@Entity
@JsonIdentityInfo(generator = ObjectIdGenerators.PropertyGenerator.class, property = "id")
public class Employee implements Serializable {

    @Id
    private Integer id;

    @JoinTable(name = "employee_intervention", joinColumns = {
        @JoinColumn(name = "employee_id", referencedColumnName = "id")}, inverseJoinColumns = {
        @JoinColumn(name = "intervention_id", referencedColumnName = "id")})
    @ManyToMany
    private List<Intervention> interventionList = new ArrayList<>();

    public Employee() {


     }

// getters and setters 
}

在这里，我使用@JsonIdentityInfo，但我尝试了之前提到的所有注释。

我收到此错误：
