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
persistence-unit name="volcano" transaction-type="RESOURCE_LOCAL">
MysqL.jdbc.Driver"/>
MysqL://localhost:3306/mydb?useUnicode=true&characterEncoding=UTF-8"/>
MysqLDialect"/>
sql" value="true"/>
sql" value="true"/>
persistence-unit>
我的spring数据jpa配置：
spring-beans-3.1.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx-3.1.xsd

最佳答案
您正在阅读错误消息错误：
Paging query needs to have a Pageable parameter!
你注释掉的方法是正确的,剩下的方法是错误的！如果你想返回Page< PSubject>从查询方法来看,此方法必须具有Pageable参数.这是可以理解的：如果您询问特定结果页面,则必须首先定义您感兴趣的页面.
Page或者如果您对所有结果感兴趣,请使用List< PSubject>：
