我正在尝试使用Spring Boot Data JPA在JPA存储库中创建一个简单的existsBy
查询。当Spring尝试在运行时创建方法时,出现错误。 existsBy
似乎是唯一遇到问题的查询类型。它可以创建findBy
查询。我的应用程序中的所有Spring Boot依赖项都使用1.5.10.RELEASE版本。
这里有一个简单的User类,它使用@IdClass
作为复合主键。
@Entity
@Table(name = "MASTER_USER")
@IdClass(UserPK.class)
public class User {
@Id
@Column(name = "USER_ID")
private String userId;
@Id
@Column(name = "TOS_ID")
private String tosId;
private boolean isCool;
// getters and setters
}
public class UserPk implements Serializable {
@Id
@Column(name = "USER_ID")
private String userId;
@Id
@Column(name = "TOS_ID")
private String tosId;
// getters and setters
}
然后在我的用户存储库中,如果有任何酷用户,我希望existsByIsCool
方法返回true。
@Repository
public interface UserRepository extends JpaRepository<User, UserPK> {
...
boolean existsByIsCool(boolean isCool);
}
一切正常,但是运行该应用程序时出现以下错误。仅对于某些堆栈跟踪上下文,该上下文位于使用Spring Security的Spring REST API中。

相关部分是

现在,如果我删除复合主键@IdClass
并仅将单个字段用作@Id
,那么一切正常,创建方法没有问题。
