这是我的测试：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "file:src/main/webapp/WEB-INF/applicationContext.xml", "classpath:test-applicationContext.xml" }) 
@TransactionConfiguration(transactionManager="transactionManager",defaultRollback=true)
public class RolTest extends AbstractTransactionalJUnit4SpringContextTests {

    @Autowired
    RolDAO rolDAO;

    @Autowired
    private SessionFactory mySessionFactory;


    private final static Logger logger = Logger.getLogger(UsuarioTest.class);

    @Test(expected=org.hibernate.exception.ConstraintViolationException.class)
    public void unicidadCampoNombre() {

        logger.info("Prueba: Se trata de insertar dos roles con el mismo nombre");

        String nombre = "Administrador";

        Rol rol1 = new Rol(nombre, "descripcion");
        Rol rol2 = new Rol(nombre, "descripcion");

        rolDAO.insert(rol1);
        rolDAO.insert(rol2);

        mySessionFactory.getCurrentSession().flush();

    }

关于这个的奇怪之处在于它曾经有效。现在，mySessionFactory.getCurrentSession().flush();抛出此异常。另一个奇怪的事情是，我对不同的对象使用相同的测试并且效果很好：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "file:src/main/webapp/WEB-INF/applicationContext.xml", "classpath:test-applicationContext.xml" }) 
@TransactionConfiguration(transactionManager="transactionManager",defaultRollback=true)
public class PermisoTest extends AbstractTransactionalJUnit4SpringContextTests {

    @Autowired
    PermisoDAO permisoDAO;

    @Autowired
    private SessionFactory mySessionFactory;


    private final static Logger logger = Logger.getLogger(UsuarioTest.class);

    @Test(expected=org.hibernate.exception.ConstraintViolationException.class)
    public void unicidadCampoNombre() {

        logger.info("Prueba: Se trata de insertar dos permisos con el mismo nombre");

        String nombre = "Eliminar";

        Permiso permiso1 = new Permiso(nombre, "descripcion");
        Permiso permiso2 = new Permiso(nombre, "descripcion");

        permisoDAO.insert(permiso1);
        permisoDAO.insert(permiso2);

        mySessionFactory.getCurrentSession().flush();

    }

有什么想法吗？？

【解决方案1】：

从 hibernate-validator 4.something 更新到 5.0.1.Final 时，我也遇到了这个问题。显然，这个版本的 hibernate-validator（可能还有其他一些 hibernate jars）缺少一些依赖项，即 el-api 和 el-ri。我通过添加这些依赖项解决了这个问题：

<dependency>
  <groupId>javax.el</groupId>
  <artifactId>el-api</artifactId>
  <version>2.2</version>
</dependency>
<dependency>
  <groupId>org.glassfish.web</groupId>
  <artifactId>el-impl</artifactId>
  <version>2.2</version>
</dependency>

在我看来，这是解决这个问题的最干净的方法。

【解决方案2】：

我在使用 hibernate 5.0.3 时遇到了类似的问题，我尝试了其他人的解决方案，但最终我唯一需要的是：

<dependency>
    <groupId>com.sun.el</groupId>
    <artifactId>el-ri</artifactId>
    <version>1.0</version>
</dependency>

【解决方案3】：

检查您的类路径并确保 InterpolationTerm 类在那里。当它试图运行单元测试时，它会抛出一个ClassDefNotFound 异常。这可能是缺少 Hibernate .jar 文件。

【讨论】：

我不明白，InterpolationTerm 类是什么？？那不是我的。类路径你的意思是文件.classpath？

【解决方案4】：

我遇到了类似的问题，对我有帮助的是添加以下依赖项。

<dependency>
        <groupId>javax.el</groupId>
        <artifactId>el-api</artifactId>
        <version>2.2</version>
</dependency>

也许这对某人有帮助。

【解决方案5】：

我遇到了这个问题。这是一个正在抱怨的休眠约束，但测试类中没有显示异常......

【讨论】：

我有同样的问题，你能提供更多细节吗？在我的映射中，我有这样的东西 @Table(name = "feedbacks",uniqueConstraints = {@UniqueConstraint(columnNames={"user_id","client_id"})})
投反对票，因为这个答案不能解决问题。
