Spring 數據 jpa - 錯誤 - 使用枚舉類型參數

Question

我對以下代碼有疑問

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}

我正在嘗試從表中檢索一些值，但不是全部。 我有這個錯誤。 我不想使用@Transient，因為它會阻止我在其他時間檢索密碼值。

問題似乎出在枚舉字段上，如果我使用適當的構造函數將其從查詢中刪除，則在啟動程序時查詢不再返回錯誤。

一定有一些簡單的事情我做得不對。

我的要求 jpa

import be.mypackage.core.domain.login.Login;

import org.springframework.data.jpa.repository.JpaRepository;

import org.springframework.data.jpa.repository.Query;


import java.util.List;



public interface LoginRepository extends JpaRepository<Login, Integer> {

@Query(value = "SELECT idLogin, identifiant, societe, loginRole FROM Login")

List<Login> findListIdentifiant();

}

findAll 查詢適用於枚舉，但我無法從查詢中排除密碼

如您所見，角色（枚舉）字段很好地使用 findAll，但不符合我的安全要求

Answer 1

您不必在查詢中列出屬性：

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

改成：

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

但是這個查詢完全是多余的，因為 JpaRepository 上有一個findAll()方法可以做到這一點。
