/** *  */package com.xyd.userDao;import java.io.Serializable;import org.springframework.data.repository.NoRepositoryBean;import org.springframework.data.repository.PagingAndSortingRepository;/** * @author admin * */@NoRepositoryBean //指明不是自己私人的领域接口//实现PagingAndSortingRepository接口，具备分页和排序功能public interface CustomRepository <T,ID extends Serializable> extends PagingAndSortingRepository<T, ID>{//这里可以写自己定义的数据操作方法}

/** *  */package com.xyd.userDao.impl;import java.io.Serializable;import javax.persistence.EntityManager;import org.springframework.data.jpa.repository.support.SimpleJpaRepository;import com.xyd.userDao.CustomRepository;/** * @author admin *实现自定义接口类 */public class CustomRepositoryImpl<T,ID extends Serializable> extends SimpleJpaRepository<T, ID> implements CustomRepository<T,ID>{private final EntityManager entityManager; /** * @param domainClass * @param em */public CustomRepositoryImpl(Class<T> domainClass, EntityManager em) {super(domainClass, em);this.entityManager = em;}}

编写userRepostory

public interface TestUserRep extends CustomRepository<User,Integer>{@Query("select u from User u where u.userName= :userName and u.email= :email")User findUser(@Param("userName")String userName,@Param("email")String email);}

最后在controller里可以使用
public class UserControler{

@AutoWired

TestUserRep userRep;

public User findUser(String userName,String email){

User user = userRep.finUser(userName,email);

}
