我遇到了这样的问题，不知道如何解决。问题是下一个：我有下一个模型：
@Entity(name="Authority")
@Table(name="AUTHORITIES")
public class Authority implements GrantedAuthority {
@Id
private long id;
@Enumerated(EnumType.STRING)
@Column(name="authority")
private asdevelopment.action.enums.Authority authority;
/**
*
*/
private static final long serialVersionUID = 1L;
@Override
public String getAuthority() {
return authority.toString();
}
/**
* @return the id
*/
public long getId() {
return id;
}
}
public enum Authority {
CLIENT_ROLE, ADMIN_ROLE;
}
我可以毫无问题地保存权限并通过 ID 获取。但是就像我在存储库中调用下一个方法一样：
domain.Authority findByAuthority(enums.Authority authority);
我得到下一个例外：
Hibernate: select top ? authority0_.id as id1_, authority0_.authority as authority1_ from AUTHORITIES authority0_ where authority0_.authority=?
