Spring Data JPA在运行测试时无法识别我的实体。请在下面找到代码。我们不使用Spring启动。

JPA配置文件（JPAConfigration_Test.xml）

存储库 

public interface DemoRepository extends JpaRepository<Demo, Integer> {}

实体 

@Entity
@Table(schema="TESTUSER1")
public class Demo {

    @Id
    private Integer id;

    @Column
    private String description;
}

测试 

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={"classpath:spring/JPAConfigration_Test.xml"})
public class LegalRequestRepositoryTest{

    @BeforeClass
    public static void  initiateJNDI() throws IllegalStateException, NamingException{
        SimpleNamingContextBuilder builder = new SimpleNamingContextBuilder();
        BasicDataSource basicDataSourceLAdvice = new BasicDataSource();
        basicDataSourceLAdvice.setDriverClassName("oracle.jdbc.OracleDriver");
        basicDataSourceLAdvice.setUsername("TESTUSER1");
        basicDataSourceLAdvice.setPassword("TESTUSER1");
        basicDataSourceLAdvice.setUrl("jdbc:oracle:thin:@localhost:1521:XE");
        builder.bind( "java:comp/env/jdbc/ladvice_service" , basicDataSourceLAdvice );
        builder.activate();
    }

    @Test
    public void testDEMO(){

    }
}

无法加载应用程序上下文。我得到的错误是

我能够连接到数据库，表格确实存在。为什么会这样？

更新1

如果在<class>中将实体添加为Persistence.xml，这似乎有效。问题似乎与packagesToScan

中的LocalContainerEntityManagerFactoryBean有关

1 个答案:

答案 0 :(得分：3)

仅在LocalContainerEntityManagerFactory上定义 no 持久性单元时才使用扫描实体。您定义了一个不包含任何持久化类的持久性单元，以便Hibernate最终知道没有任何类。

您完整persistence.xml似乎是多余的，因为您只需复制LCEMFB上已有的配置。我建议删除它，让Spring扫描实体。
