-- 如果@Query註解加上nativeQuery=true 則查詢語句使用原生sql，不加則使用HQL

一、jpa 原生insert的sql語句：

    @Modifying     @Query(value = "insert into t_sys_org_user(org_id,user_id) values(?1,?2)",nativeQuery = true)     int addUserToOrg(Long orgId,Long userId);         jpa 原生delete的sql語句：

 @Modifying     @Query(value = "delete from t_sys_org_user where org_id=?1 and user_id=?2",nativeQuery = true)     int deleteUserFromOrg(Long orgId,Long userId);         jpa 原生update的sql語句：

@Modifying     @Query(value = "update t_sys_user set status=0 where user_id=?1",nativeQuery = true)     int updateUserStatus(Long userId);         jpa 原生select的sql語句：

//jpa 多對多關係的表聯合查詢 DAO層 @Query(value = "select s from SysUserDTO s left join s.sysOrgDTOSet o where (?1 is null or s.username like ?1) and (?2 is null or o.name like ?2)")     Page<SysUserDTO> findByUsernameAndOrgName(String username, String orgName, Pageable pageable); // service層 public Page<SysUserDTO> findByUsernameAndOrgName(String username, String orgName, Pageable pageable){         String name = (username==null)?null:"%"+username+"%";         String orgname = (orgName==null)?null:"%"+orgName+"%";         return sysUserDAO.findByUsernameAndOrgName(name,orgname,pageable);     } 二、jpa hql中使用in關鍵字

@Query(value = "select distinct r from SysRoleDTO r left join r.sysOrgDTOSet o where (?1 is null or r.name like ?1) "+            "and (?2 is null or r.code like ?2) and o.id in (?3)")    Page<SysRoleDTO> findAllRole(String name, String code, List<Long> ids, Pageable pageable); @Transactional     @Modifying     @Query("delete from MeetingQRSign where mpid = ?1")     void deleteByMpid(String mpid);       @Modifying     @Query("update AccountEntity w set w.version=:version where w.id=:id")     void update(@Param("version") int version,@Param("id") String id);
