当我尝试导航到一个端点时,我会得到以下错误
Type definition error: [simple type, class org.hibernate.proxy.pojo.bytebuddy.ByteBuddyInterceptor]; nested exception is com.fasterxml.jackson.databind.exc.InvalidDefinitionException: No serializer found for class org.hibernate.proxy.pojo.bytebuddy.ByteBuddyInterceptor and no properties discovered to create BeanSerializer (to avoid exception, disable SerializationFeature.FAIL_ON_EMPTY_BEANS)
我检查了所有的模型,所有的属性都有 getter 和 setter?
我可以通过添加 spring.jackson.serialization.fail-on-empty-beans=false
来解决这个问题,但我认为这只是一个隐藏异常的工作。

型号:
@Entity
public class Product {
private int id;
private String name;
private String photo;
private double price;
private int quantity;
private Double rating;
private Provider provider;
private String description;
private List<Category> categories = new ArrayList<>();
private List<Photo> photos = new ArrayList<>();
// Getters & Setters
}
PagedResponse

public class PagedResponse<T> {
private List<T> content;
private int page;
private int size;
private long totalElements;
private int totalPages;
private boolean last;
// Getters & Setters
}
RestResponse
课程:
public class RestResponse<T> {

在我的控制器中返回 ResponseEntity<RestResponse<PagedResponse<Product>>>
