我正在尝试遍历java中sdid的记录列表。 sdid记录设置为具有相同sdid的最多8条记录,但需要检查每个sdid的状态列,以查看其PEND_ADD
,PEND_DEL
和ACTIVE
。
因此,对于第一个条件:状态为PEND_ADD
或PEND_DEL
。然后删除记录。
如果状态仅为ACTIVE
,则删除记录。
如果状态为ACTIVE
,PEND_ADD
和/或PEND_DEL
,则删除PEND_ADD
和/或PEND_DEL
并保留ACTIVE
private void disconnectClassOfService(List<Integer> sdidList) throws Exception {
if (sdidList == null || sdidList.isEmpty()){
return;
}
logger.info("Start deleting sdid : " + sdidList);
for (Integer sdid : sdidList ) {
List<CosPolicy2Interface> cosPolicy2InterfaceBySdid = getCosPolicy2InterfaceDAO().getCosPolicy2InterfaceBySdid(sdid);
if (cosPolicy2InterfaceBySdid != null && !cosPolicy2InterfaceBySdid.isEmpty()){
for (CosPolicy2Interface cosPolicySdid: cosPolicy2InterfaceBySdid){
if (cosPolicySdid.getStatus().equals("PEND_ADD") ){
getPersistMgr().delete(cosPolicySdid);
}
if (cosPolicySdid.getStatus().equals("PEND_DEL") ){
getPersistMgr().delete(cosPolicySdid);
}
if (cosPolicySdid.getStatus().equals("ACTIVE") ){
getPersistMgr().delete(cosPolicySdid);
}
}
}
我的hibernate查询
protected static final String queryBySdid = " SELECT * "
+ " FROM cos_policy2interface "
+ " WHERE connection_type = 'SDID' AND connection_id = ?";
@Override
public List<CosPolicy2Interface> getCosPolicy2InterfaceBySdid(
long sdid) throws Exception {
EntityManager em = getEntityManager();
CosPolicy2Interface CosPolicy2Interface = null;
Query query = em.createNativeQuery(queryBySdid, CosPolicy2Interface.class);
query.setParameter(1, sdid);
@SuppressWarnings("unchecked")
List<CosPolicy2Interface> cosPolicy2InterfaceList = query.getResultList();
return cosPolicy2InterfaceList;
}
表的例子:
CosPolicy2Interface_id,connection_type, connection_id, status
29, 'SDID', 13538806, ACTIVE
30, 'SDID', 13538806, PEND_DEL
31, 'SDID', 13538806, ACTIVE
32, 'SDID', 13538806, PEND_ADD
33, 'SDID', 13538806, PEND_ADD
34, 'SDID', 13538806, ACTIVE
My logic will erased all of it since it will iterate one record at a time. Could I use a boolean? some thing like this how can I implemented.
1) Pen Add -> dont care delete (But set PendingFlag to true)
2)Pend Del --> dont care delete (Set Pending Flag to true)
3) Active --> Store them in a list to check later
Come out of the for-loop and check if pendingFlag is false and activeCosList is not empty --> delete them
答案 0 :(得分:1)
我想修改您的disconnectClassOfService
方法。
private void disconnectClassOfService(List<Integer> sdidList) throws Exception {
if (sdidList == null || sdidList.isEmpty()) {
return;
}
logger.info("Start deleting sdid : " + sdidList);
for (Integer sdid : sdidList) {
List<CosPolicy2Interface> cosPolicy2InterfaceBySdid = getCosPolicy2InterfaceDAO().getCosPolicy2InterfaceBySdid(sdid);
if (cosPolicy2InterfaceBySdid != null && !cosPolicy2InterfaceBySdid.isEmpty()) {
List<CosPolicy2Interface> recordsACTIVE = new ArrayList<>();
List<CosPolicy2Interface> recordsNonACTIVE = new ArrayList<>();
for (CosPolicy2Interface cosPolicySdid : cosPolicy2InterfaceBySdid) {
if (cosPolicySdid.getStatus().equals("PEND_ADD")) {
recordsNonACTIVE.add(cosPolicySdid);
}
if (cosPolicySdid.getStatus().equals("PEND_DEL")) {
recordsNonACTIVE.add(cosPolicySdid);
}
if (cosPolicySdid.getStatus().equals("ACTIVE")) {
recordsACTIVE.add(cosPolicySdid);
}
}
if ((recordsACTIVE.size() == cosPolicy2InterfaceBySdid.size())) {
getPersistMgr().deleteAll(cosPolicy2InterfaceBySdid);// Delete all records
} else {
// delete non active records
getPersistMgr().deleteAll(recordsNonACTIVE);
}
}
}
}
这样您就不必单独删除记录了。
