问题描述
项目中使用了spring data jpa，自己扩展了一个全局接口AbstractJxetRepositorypublic interface AbstractJxetRepository<T> {public void batchInster(List<T> list, int size) throws Exception;public void batchUpdate(List<T> list, int size) throws Exception;}实现类AbstractDao@NoRepositoryBeanpublic abstract class AbstractDao<T> implements AbstractJxetRepository<T> {@PersistenceContextprotected EntityManager em;@Transactionalpublic 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();}}}@Transactionalpublic 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();}}}}在一个模块接口中继承AbstractJxetRepositorypublic interface EduUnitLevelDao extends PagingAndSortingRepository<EduUnitLevel, Integer>,JpaSpecificationExecutor<EduUnitLevel> {public List<EduUnitLevel> getBySchoolId(Integer schoolId);@SuppressWarnings("unchecked")public EduUnitLevel save(EduUnitLevel eduUnitLevel);public List<EduUnitLevel> save(List<EduUnitLevel> eduUnitLevels);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org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'cn.com.jxet.datalayer.service.EduUnitLevelServiceTest': Injection of autowired dependencies failed;

解决方案
No property batch found for type cn.com.jxet.datalayer.entity.EduUnitLevel 1、spring data jpa 没识别你这个东西 public void batchInster(List<T> list, int size) throws Exception; public void batchUpdate(List<T> list, int size) throws Exception; 2、你这么写不对的public abstract class AbstractDao<T> implements AbstractJxetRepository<T> { 3、注册有两种方式：3.1、如果单个模块需要UserRepository2.java 接口UserRepository2Impl.java 实现https://github.com/zhangkaitao/es/tree/master/common/src/test/java/com/sishuok/es/common/repository3.2、如果所有模块都需要：注册方式 <jpa:repositories base-package="com.sishuok.es.**.repository" repository-impl-postfix="Impl" factory-class="com.sishuok.es.common.repository.support.SimpleBaseRepositoryFactoryBean" entity-manager-factory-ref="entityManagerFactory" transaction-manager-ref="transactionManager"> </jpa:repositories>https://github.com/zhangkaitao/es/blob/master/web/src/main/resources/spring-config.xml
