spring boot jackson infinite recursion
// some solutions:
public class Product {
@NotNull
@ManyToOne(cascade = {CascadeType.PERSIST, CascadeType.MERGE, CascadeType.REFRESH}, fetch = FetchType.LAZY)
@JoinColumn(name = "category_id", nullable = false)
@JsonBackReference
private Category category;
}
public class Category {
@OneToMany(cascade=CascadeType.ALL, fetch = FetchType.LAZY, mappedBy = "category")
@JsonManagedReference
private List<Product> products = new ArrayList<>();
}
// ______________________________________________
@JsonIdentityInfo(
generator = ObjectIdGenerators.PropertyGenerator.class,
property = "id")
public class Product {
...
}
@JsonIdentityInfo(
generator = ObjectIdGenerators.PropertyGenerator.class,
property = "id")
public class Category {
...
}
//________________________
// Just use @JsonIgnore on one of the sides
