Hibernate 5将已经存在于DB中的id指定为preinitialization - org.springframework.dao.DataIntegrityViolationException

时间：2016-01-26 10:09:00

标签： spring hibernate hsqldb

我打算从Spring 4.2.1.RELEASe + Hibernate 4.2.19.Final迁移到4.2.1.RELEASe + Hibernate 5.0.7.Final。

我创建了一个简单的项目available on Github来测试新的Hibernate版本并遇到了一个问题：在我的集成测试中，我使用sql文件中的两行初始化HSQLDB。关键是当我的Hibernate版本是4.2.19时，来自ExampleIntegrationTRTest的所有测试都通过了。但是对于5.0.7.Final，第一个测试（testExampleInsertWithRollback）失败了：

脚本/ initData.sql 

INSERT INTO TFOEMPLE(FOEMPLE_ID, FOEMPLE_NAME) values(1, 'Louis');
INSERT INTO TFOEMPLE(FOEMPLE_ID, FOEMPLE_NAME) values(2, 'Maria');

ExampleIntegrationTRTest.testExampleInsertWithRollback ：此测试以4.1传递，但由于5.0.7.Final中的javax.persistence.EntityExistsException而失败。显然它试图创建新的FooEmployee，为它分配一个id，它已作为初始化的一部分存在于DB中。

@ContextConfiguration({ "/spring/test/test-context.xml" })
@Test
public class ExampleIntegrationTRTest extends AbstractTransactionalTestNGSpringContextTests {

    @Transactional
public void testExampleInsertWithRollback() {

    FooEmployee response = null;
    response = fooUserService.getEmployee(1);
    //response is FooEmpleado ( BaseEntity ( FooEmployee@590013c7    id = 1     )    id = 1    nombre = Louis     )

    FooEmployee newFoo = new FooEmployee();
    newFoo.setName("James");
    createdFooWithRollback = fooUserService.createEmployee(newFoo).getId();
    //The line above throws the exception

    assertNotNull(createdFooWithRollback);
    EntityManagerHolder holder = (EntityManagerHolder)TransactionSynchronizationManager.getResource(entityManagerFactory);
    EntityManager em = holder.getEntityManager();
    em.flush();

    em.clear();

    response = null;
    response = fooUserService.getEmployee(createdFooWithRollback);

    assertNotNull(response);
    assertEquals(response.getId(), createdFooWithRollback);
    assertEquals(response.getName(), "James");

}

以下是4.2.19.Fina l和5.0.7.Final

生成的表格创建日志

<强> 4.2.19.Final 

create table TFODEPAR (
    FODEPAR_ID integer generated by default as identity (start with 1),
    FODEPAR_NAME varchar(255),
    primary key (FODEPAR_ID)
)

<强> 5.0.7.Final 

create table TFODEPAR (
    FODEPAR_ID integer not null,
    FODEPAR_NAME varchar(255),
    primary key (FODEPAR_ID)
)

在4.2.19.Final中，id列生成为标识列，而在5.0.7.Final中，它生成为普通的非可空列。我怀疑罪魁祸首是@GeneratedValue(strategy=GenerationType.AUTO)选择正确的id生成策略的方式。似乎在版本5之前，它正在挑选GenerationType.IDENTITY，而在版本5中则不是。{

因此，要解决此问题，请将@GeneratedValue(strategy=GenerationType.AUTO)更改为@GeneratedValue(strategy=GenerationType.IDENTITY)，以强制告诉hibernate将id列作为标识列。
