我正在尝试Spring数据JPA,在启动我的项目时,我收到以下错误:

这是我的存储库:
public interface SubjectRepository extends Repository<PSubject, String>{
//public Page<PSubject> findByType(String type, Pageable pageable);
public Page<PSubject> findByType(String type);
//public Page<PSubject> findByMacaddress(String macaddress, Pageable pageable);
public Page<PSubject> findByMacaddress(String macaddress);
public Page<PSubject> findByUri(String uri);
}
正如您所看到的,我已经评论了使用pageble的方法,并将父接口从jparepository更改为repository.But我仍然收到上述错误消息。有没有与persistence.xml相关的东西? 我的persistence.xml

答案 0 :(得分:16)
您正在阅读错误消息:
Paging query needs to have a Pageable parameter!
您注释掉的方法是正确的,剩下的方法是错误的!如果要从查询方法返回Page<PSubject>
,则此方法必须具有Pageable
参数。这是可以理解的:如果您询问特定的结果页面,您必须首先定义您感兴趣的页面。
Page<PSubject> findByType(String type, Pageable pageable);
Page<PSubject> findByType(String type, Pageable pageable);
Page<PSubject> findByMacaddress(String macaddress, Pageable pageable);
Page<PSubject> findByMacaddress(String macaddress, Pageable pageable);
Page<PSubject> findByUri(String uri, Pageable pageable);
如果您对所有结果感兴趣,请使用List<PSubject>
:
Page<PSubject> findByType(String type, Pageable pageable);
List<PSubject> findByType(String type);
Page<PSubject> findByMacaddress(String macaddress, Pageable pageable);
List<PSubject> findByMacaddress(String macaddress);
List<PSubject> findByUri(String uri);
答案 1 :(得分:6)
确保您要从org.springframework.data.domain.Pageable;中导入Pageable对象;
答案 2 :(得分:1)
就我而言,导入是错误的(来自 java.awt.print.Pageable)。 正确的一个是:org.springframework.data.domain.Pageable
