我正在尝试以下JPQL，但是失败了：

Query query = em.createQuery("SELECT u FROM User u WHERE 'admin' MEMBER OF u.roles");
List users = query.query.getResultList();

我得到以下异常：

ERROR [main] PARSER.error(454) | <AST>:0:0: unexpected end of subtree
java.lang.IllegalArgumentException: org.hibernate.hql.ast.QuerySyntaxException: unexpected end of subtree [SELECT u FROM com.online.data.User u WHERE 'admin' MEMBER OF u.roles] ERROR [main] PARSER.error(454) | <AST>:0:0: expecting "from", found '<ASTNULL>'
...
...
Caused by: org.hibernate.hql.ast.QuerySyntaxException: unexpected end of subtree [SELECT u FROM com.online.data.User u WHERE 'admin' MEMBER OF u.roles]

我有Spring 3.0.1.RELEASE，Hibernate 3.5.1-Final和Maven来粘合依赖项。

用户类别：

@Entity
public class User {
  @Id
  @Column(name = "USER_ID")
  @GeneratedValue(strategy = GenerationType.IDENTITY)
  private long id;
  @Column(unique = true, nullable = false)
  private String username;

  private boolean enabled;

  @ElementCollection
  private Set<String> roles = new HashSet<String>();

...
}

我正在运行单元测试以检查配置，并且我能够运行其他JPQL查询，但我无法运行的唯一条件是IS EMPTY，MEMBER OF条件。

完整的单元测试如下：

测试整合

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations =  { "/spring/dataLayer.xml"})
@Transactional
@TransactionConfiguration
public class TestUserDaoImplIntegration {
  @PersistenceContext
  private EntityManager em;

  @Test
  public void shouldTest() throws Exception {
    try {
//WORKS
Query query = em.createQuery("SELECT u FROM User u WHERE 'admin' in elements(u.roles)"); 
List users = query.query.getResultList();
    } catch (Exception e) {
      e.printStackTrace();
      throw e;
    }
    try {
//DOES NOT WORK
Query query = em.createQuery("SELECT u FROM User u WHERE 'admin' MEMBER OF u.roles"); 
List users = query.query.getResultList();
    } catch (Exception e) {
      e.printStackTrace();
      throw e;
    }
  }
}
