Question

我是一个有两个字段的简单Person实体：

@Entity
@Table(name = "person")
public class Person implements Serializable {

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long id;

    @Column(name = "name", length = 50)
    private String name;

    //setter/getters
}

我在JpaRepository中覆盖findAll方法以根据用户角色限制记录：

public interface PersonRepository extends JpaRepository<Person,Long> {

    @Query("select p from Person p where p.name like ?#{hasRole('ROLE_ADMIN') ? '%' : principal.username}")
    @Override
    List<Person> findAll();
}

以上设置工作正常。但是当我将查询更新为以下内容时，它会抛出异常，如下所示。它看起来无法解析SpEL表达式。

有问题的查询：

@Query("select p from Person p where p.id like ?#{hasRole('ROLE_ADMIN') ? '%' : principal.userId}")

例外：

我玩了它并尝试了以下选项，但得到了同样的例外：

1）用=

替换LIKE

@Query("select p from Person p where p.id = ?#{hasRole('ROLE_ADMIN') ? '1' : principal.userId}")

2）设置硬编码ID：

@Query("select p from Person p where p.id = ?#{hasRole('ROLE_ADMIN') ? '6' : '5'}")

有什么建议吗？

仅供参考：

我的春季启动1.3.6.RELEASE，hibernate 4.3.11.Final在我的pom.xml中。
我已经正确配置/覆盖了 org.springframework.security.core.userdetails.User对象传递用户ID。

我不确定SpEL解析器和Spring Data JPA之间是否存在冲突。但我发现了一个解决方法：

<强>解决方案： @Query上的以下更改工作正常：

@Query("select p from Person p where p.id = ?#{principal.customerId} or 1=?#{hasRole('ROLE_ADMIN') ? 1 : 0}")

Spring SpEL JPA @Query - 获取＆＃34; QueryException：并未设置所有命名参数＆＃34;使用数字列
