无法创建查询元模型Spring Data JPA存储库（奇怪的行为）

Question

我的JPA存储库中出现意外错误。 由于与JPA相关的异常，Spring无法创建回购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]

我的回购代码如下：

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);
}

现在很奇怪的是，它会为第一个查询显示错误，该查询在添加第二个方法之前可以完美地找到，如果我删除了第二个查询，代码可以正常工作。

实体的代码是这样的

@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吗

 public interface FooRepository extends JpaRepository<Foo, Long> {
