spring data jpa的误将方法名当成属性名称的问题

  • spring
  • hibernate

项目中使用了spring data jpa,自己扩展了一个全局接口AbstractJxetRepository
[code="java"]public interface AbstractJxetRepository {

public void batchInster(List<T> list, int size) throws Exception;

public void batchUpdate(List<T> list, int size) throws Exception;

}[/code]

实现类AbstractDao
[code="java"]@NoRepositoryBean
public abstract class AbstractDao implements AbstractJxetRepository {

@PersistenceContext
protected EntityManager em;

@Transactional
public void batchInster(List<T> list, int size) throws Exception{
    for (int i = 0; i < list.size(); i++) {
        em.persist(list.get(i));
        if (i % size == 0) {
            em.flush();
            em.clear();
        }
    }
}

@Transactional
public void batchUpdate(List<T> list, int size) {
    for (int i = 0; i < list.size(); i++) {
        em.merge(list.get(i));
        if (i % size == 0) {
            em.flush();
            em.clear();
        }
    }
}

}[/code]

在一个模块接口中继承AbstractJxetRepository
[code="java"]public interface EduUnitLevelDao extends PagingAndSortingRepository,
JpaSpecificationExecutor {

public List<EduUnitLevel> getBySchoolId(Integer schoolId);

@SuppressWarnings("unchecked")
public EduUnitLevel save(EduUnitLevel eduUnitLevel);

public List<EduUnitLevel> save(List<EduUnitLevel> eduUnitLevels);[/code]

现在的问题是,在service中调用EduUnitLevelDao ,会将batchInster方法中的batch当做EduUnitLevel的属性,提示No property batch found for type cn.com.jxet.datalayer.entity.EduUnitLevel

全部的报错信息
