这是我在使用时得到的异常 查找方法. 我正在使用 Spring Boot JPA 存储库。

@Entity

@Table(名称 ="商店"( 公共类 StoreEntity {

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long store_id;
private String storeDescription;
private String storeName;
private String lattitude;
private String longitude;
private boolean isActive;
private boolean is247;
private Date createdDate;
private Date lastModifiedBy;
@OneToMany(mappedBy = "store", cascade = CascadeType.ALL)
@JsonIgnoreProperties(value ="store", allowSetters=true)
private Set<GroceryItemEntity> groceryItem;

@Table(名称="杂货店"( public class GroceryItemEntity {

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long grocery_id;
private String name;
private String description;
private double price;
private boolean isActive;
private Date  createdDate;  
private Date  lastModifiedBy;

@ManyToOne(cascade = CascadeType.ALL )
@JoinColumn(name = "store_id")
@JsonIgnoreProperties(value ="groceryItem", allowSetters=true)
private StoreEntity store;

Answer 1

@JsonIgnoreProperties(value ="groceryItem", allowSetters=true)

用于所有映射，修复无限递归问题。

实际上，我更改了应用程序的结构。在端点中使用 vo 而不是实体类
