问题:

I am trying spring data JPA, when starting my project, I got the following error:

Caused by: 
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'subjectRepository': FactoryBean threw exception on object creation; nested exception is java.lang.IllegalArgumentException: Paging query needs to have a Pageable parameter!

Here is my repository:

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);

}

As you can see I have comment the method of using pageble, and changed the parent interface from jparepository to repository.But I am still getting the above error message. Is there anything related to persistence.xml ? My persistence.xml

<persistence version="1.0"

        </properties>
    </persistence-unit>
</persistence>

And my spring data jpa configuration:

You are reading the error message wrong:

Paging query needs to have a Pageable parameter!

The methods you have commented out are correct, the remaining ones are wrong! If you want to return Page<PSubject> from a query method, this method must have Pageable argument. This is understandable: if you are asking about specific page of results, you must first define which page are you interested in.

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);

Or you if you are interested about all results use 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);
