Spring data jpa - 错误 - 带有枚举类型参数

Question

下面的代码有问题

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'loginController' defined in file [C:\Users\USERNAME\IdeaProjects...\application\ui\security\controller\LoginController.class]: Unsatisfied dependency expressed through constructor parameter 2; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'loginServiceImpl' defined in file [C:\Users\USERNAME\IdeaProjects\...\core\domain\login\LoginServiceImpl.class]: Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'loginRepository' defined in be.mypackage.core.persistence.LoginRepository defined in @EnableJpaRepositories declared on DomainConfig: Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Validation failed for query for method public abstract java.util.List be.mypackage.core.persistence.LoginRepository.findListIdentifiant()!

Caused by: org.hibernate.QueryException: No data type for node: org.hibernate.hql.internal.ast.tree.IdentNode 
 \-[IDENT] IdentNode: 'loginRole' {originalText=loginRole}

我正在尝试从表中检索一些值，但不是全部。我有这个错误。 我不想使用@Transient，因为它会阻止我在其他时间检索密码值。

问题似乎出在枚举字段上，如果我从查询中删除它，使用适当的构造函数，启动程序时查询不再返回错误。

肯定有一些简单的事情我做得不对。

findAll 查询适用于枚举，但我无法从查询中排除密码

如您所见，角色（枚举）字段可以很好地使用 findAll，但不符合我的安全要求

Answer 1

您不必在查询中列出属性：

@Query(value = "SELECT idLogin, identifiant, societe, loginRole FROM Login")
List<Login> findListIdentifiant();

改为：

@Query(value = "SELECT l FROM Login l")
List<Login> findListIdentifiant();

但是这个查询完全是多余的，因为 JpaRepository 上有一个 findAll() 方法可以做到这一点。
