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();

    }

奇怪的是，这曾经有效。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？

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(也许还有其他一些 hibernate jar)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，这是解决此问题的最干净的方法。
