这是我在使用 Find Method 时遇到的异常。我正在使用 Spring Boot JPA 存储库。

@Entity

@Table(name ="Store") 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(name ="Grocery") 公共类 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;

解决方案

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

用于 All Mapping 以解决无限递归的问题。

实际上我改变了我的应用程序的结构。在端点而不是实体类中使用了 Vo
