我正在尝试以下 JPQL，但它失败了：
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。
用户等级：
@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>();
...
}

我正在运行一个单元测试来检查配置，并且我能够运行其他 JPQL 查询，我唯一无法运行的是 IS EMPTY、MEMBER OF 条件。
完整的单元测试如下：
测试集成
@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;
}
}
}
