随笔-记录list遍历remove使用中间list

List<MonitorModelRule> monitorModelRulesNew=modelAndRuleVo.getMonitorModelRules();
Map<String, Object> params = new HashMap<String, Object>();
params.put("businessCode",monitorModel.getBusinessCode());
List<MonitorModelRule> monitorModelRulesOld=monitorModelRuleService.findByParams(params);
List<MonitorModelRule> insertList=new ArrayList<MonitorModelRule>();
List<MonitorModelRule> updateList=new ArrayList<MonitorModelRule>();
for(MonitorModelRule monitorModelRule1:monitorModelRulesNew){
if(monitorModelRule1.getSid()==null){
insertList.add(monitorModelRule1);
} else {
updateList.add(monitorModelRule1);
}
}
List<MonitorModelRule> centerList=new ArrayList<MonitorModelRule>();
for(MonitorModelRule monitorModelRule3:monitorModelRulesOld){
for(MonitorModelRule monitorModelRule4:updateList){
if(monitorModelRule4.getSid()==monitorModelRule3.getSid()){
centerList.add(monitorModelRule3);
}
}
}
monitorModelRulesOld.removeAll(centerList);
for(MonitorModelRule monitorModelRule5:monitorModelRulesOld){
monitorModelRule5.setDelFlg(true);
}
updateList.addAll(monitorModelRulesOld);
