我想使用 Spring Specification 和 JPA CriteriaBuilder 构建一个动态过滤器。但是有一些问题:
- 我的根类 Product 与 Images @OneToMany 有关系，所以我获取重复的结果。我决定使用 Distinct。它有效，但有一个新问题:
- 我的根类产品也与 ProductDetails @ManyToOne 有关系，当我在查询中使用 orderBy productDetails.price 时，出现以下错误:
2019-10-22 17:51:36.391 ERROR 14258 --- [nio-8080-exec-5] o.h.engine.jdbc.spi.SqlExceptionHelper : Expression #1 of ORDER BY clause is not in SELECT list, references column 'glasses.productdet1_.price' which is not in SELECT list; this is incompatible with DISTINCT
2019-10-22 17:51:36.419 ERROR 14258 --- [nio-8080-exec-5] o.a.c.c.C.[.[.[/].[dispatcherServlet] : Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is org.springframework.orm.jpa.JpaSystemException: could not extract ResultSet; nested exception is org.hibernate.exception.GenericJDBCException: could not extract ResultSet] with root cause
有人可以帮我解决我的问题吗？因为我已经尽力了... 提前致谢!
我的产品实体
@Entity
public class Product extends AuditModel {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
long id;
@ManyToOne
@JoinColumn(name = "product_details_id")
ProductDetails productDetails;
@JsonManagedReference
@OneToMany(mappedBy = "product",
fetch = FetchType.LAZY,
cascade = CascadeType.ALL,
orphanRemoval = true)
List<Image> images = new ArrayList<>();
我的图片实体
@Entity
public class Image {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
Long id;
String imageName;
String imageType;
boolean isMainImage;
@JsonBackReference
@ManyToOne(fetch = FetchType.LAZY)
Product product;
我的 ProductDetails 实体
@Entity
public class ProductDetails {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
long id;
int modelNumber;
int price;
@JsonIgnore
@OneToMany(fetch = FetchType.LAZY,
cascade = CascadeType.ALL,
mappedBy = "productDetails")
List<Product> products = new ArrayList<>();
我的 CriteriaBuilder 方法:
public Specification<Product> runCriteriaBuilder(
String category,
String sortBy,
String sortDirection,
Integer minPrice,
Integer maxPrice,
) {
return new Specification<Product>() {
@Override
public Predicate toPredicate(Root<Product> root, CriteriaQuery<?> query, CriteriaBuilder criteriaBuilder) {
Join<Product, ProductDetails> productDetailsJoin = root.join(Product_.productDetails, JoinType.LEFT);
Join<Product, Category> categoryJoin = root.join(Product_.category, JoinType.INNER);
Join<Product, Image> productsImagesJoin = root.join(Product_.images, JoinType.LEFT);
List<Predicate> predicates = new ArrayList<>();
if (minPrice != null && maxPrice != null) {
predicates.add(criteriaBuilder.between(productDetailsJoin.get(ProductDetails_.price), minPrice, maxPrice));
}
if (sortDirection.equalsIgnoreCase("desc")) {
if (sortBy.equalsIgnoreCase("price")) {
query.orderBy(criteriaBuilder.desc(productDetailsJoin.get("price")));
} else if (sortBy.equalsIgnoreCase("productnumber")) {
query.orderBy(criteriaBuilder.desc(root.get("productNumber")));
}
} else {
if (sortBy.equalsIgnoreCase("price")) {
query.orderBy(criteriaBuilder.asc(productDetailsJoin.get("price")));
} else if (sortBy.equalsIgnoreCase("productnumber")) {
query.orderBy(criteriaBuilder.asc(root.get("productNumber")));
}
}
return criteriaBuilder.and(predicates.toArray(new Predicate[predicates.size()]));
}
};
}
更改后我的新错误
Join<Product, ProductDetails> productDetailsJoin = root.join(Product_.productDetails, JoinType.LEFT);
到
Join<Product, ProductDetails> productDetailsJoin = (Join<Product, ProductDetails>) root.fetch(Product_.productDetails, JoinType.LEFT);

最佳答案
您需要 JOIN FETCH @ManyToOne 关联，因为 SQL ORDER BY 子句在 之后执行code>SELECT 子句被评估。
所以不是这个:
Join<Product, ProductDetails> productDetailsJoin = root
.join(
Product_.productDetails,
JoinType.LEFT
);
你需要这样:
Join<Product, ProductDetails> productDetailsJoin = (Join<Product, ProductDetails>) root
.fetch(
Product_.productDetails,
JoinType.LEFT
);
强制转换是必需的，因为 fetch 方法返回一个 javax.persistence.criteria.Fetch 引用，而您需要一个 Join 引用.
关于spring - 如何在 JPA Criteria API 中为 @ManyToOne 关联组合 DISTINCT 和 ORDER BY？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/58508415/
