無法創建查詢元模型Spring Data JPA存儲庫（奇怪的行為）

Question

我的JPA存儲庫中出現意外錯誤。 由於與JPA相關的異常，Spring無法創建回購bean。

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'fooRepository': Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Could not create query metamodel for method public abstract com.xxxxx.entities.Foo com.xxxxx.repositories.FooRepository.findByCourierId(java.lang.Long)!

Caused by: java.lang.IllegalArgumentException: Unable to locate Attribute  with the the given name [courierId] on this ManagedType [com.xxxxx.core.models.XXXObject]

我的回購代碼如下：

public interface FooRepository extends XXXRepository<Foo> {

    Foo findByCourierId(Long courierId);

    @Query("SELECT CA " +
        "FROM Foo CA " +
        "WHERE CA.courier.id IN (?1)")
    List<Foo> findByCourierIds(List<Long> courierIds);
}

現在很奇怪的是，它會為第一個查詢顯示錯誤，該查詢在添加第二個方法之前可以完美地找到，如果我刪除了第二個查詢，代碼可以正常工作。

實體的代碼是這樣的

@Entity
public class Foo extends XXXObject {

    @OneToOne
    @JoinColumn(name = "courier_id")
    private Courier courier;
....

Answer 1

代替

public interface FooRepository extends XXXRepository<Foo> {

您可以使用JPARepository嗎

 public interface FooRepository extends JpaRepository<Foo, Long> {
