實現類似微信朋友圈功能（一 ）只供自己好友可見的點贊和評論

先來看看功能的需求

 

跟微信朋友圈一樣的功能。

我是分步驟做：

1：先查看朋友圈。查看的都是自己的好友。點贊和評論是好友才能看見。不是好友就隱藏看下圖。三個不用的用戶登錄

在展示的接口我先查詢出當前好友的點贊和評論的用戶集合。

 

doctorId = inputFields.doctorId;     //當前醫生人

	
	partyIds.add(doctorId);		
	andExprs = FastList.newInstance();
	andExprs.add(EntityCondition.makeCondition("partyId", EntityOperator.EQUALS, doctorId));
	//查詢用戶屏蔽的人
	if("appTypeEnum_0".equals(partyClient)){
		shieldingPartys = ParameterSettingServices.getShieldingParty(delegator,doctorId,inputFields.partyClient);
		if(shieldingPartys)
			andExprs.add(EntityCondition.makeCondition("friendId", EntityOperator.NOT_IN, shieldingPartys));
	}
	andExprs.add(EntityCondition.makeCondition("addStatusEnum", EntityOperator.EQUALS, "addStatusEnum_2"));
	andExprs.add(EntityCondition.makeCondition("thruDate", EntityOperator.EQUALS, null));
	andExprs.add(EntityCondition.makeCondition("partyClient", EntityOperator.EQUALS, inputFields.partyClient));
	andCond = EntityCondition.makeCondition(andExprs, EntityOperator.AND);
	//我的好友（不再黑名單中的）
	myFriendsList = delegator.findList("MyFriends",andCond, UtilMisc.toSet("friendId"), null, null, true);//非我屏蔽的好友；
	
	
	andExprs = FastList.newInstance();
	if("appTypeEnum_0".equals(partyClient)){
		shieldingPartys = ParameterSettingServices.getShieldingParty(delegator,doctorId,inputFields.partyClient);
		if(shieldingPartys)
			andExprs.add(EntityCondition.makeCondition("beConcernId", EntityOperator.NOT_IN, shieldingPartys));
	}
	andExprs.add(EntityCondition.makeCondition("partyId", EntityOperator.EQUALS, doctorId));
	andExprs.add(EntityCondition.makeCondition("partyClient", EntityOperator.EQUALS, inputFields.partyClient));
	andExprs.add(EntityCondition.makeCondition("thruDate", EntityOperator.EQUALS, null));
	andCond = EntityCondition.makeCondition(andExprs, EntityOperator.AND);
	//我關注的人（不再黑名單中的）
//	concernList = delegator.findList("Concern",andCond, UtilMisc.toSet("beConcernId"), null, null, true);
//	
//	if(concernList){
//		beConcernIdList = EntityUtil.getFieldListFromEntityList(concernList, "beConcernId", true);//非我屏蔽的我關注的人
//		if(beConcernIdList){
//			partyIds.addAll(beConcernIdList);
//		}
//	}
	if(myFriendsList){
		friendIdList = EntityUtil.getFieldListFromEntityList(myFriendsList, "friendId", true);
		if(friendIdList){
			partyIds.addAll(friendIdList);
		}
	}
	//我的好友和我關注的人（非黑名單中的）去重
	partyIds = new ArrayList(new HashSet(partyIds));
	

partyIds是當前醫生的好友和關注列表 對比 如果是好友相同的則顯示
然后查找我的關注和我的好友 列表集合

//當前登錄人不為空
		loginId=partyId;//當前登錄人
		/**
		 * 當前登錄人的好友和關注列表
		 */
		loginIds.add(loginId);		
		andExprse = FastList.newInstance();
		andExprse.add(EntityCondition.makeCondition("partyId", EntityOperator.EQUALS, loginId));
		//查詢用戶屏蔽的人
		if("appTypeEnum_0".equals(partyClient)){
			shieldingPartys = ParameterSettingServices.getShieldingParty(delegator,loginId,inputFields.partyClient);
			if(shieldingPartys)
				andExprse.add(EntityCondition.makeCondition("friendId", EntityOperator.NOT_IN, shieldingPartys));
		}
		andExprse.add(EntityCondition.makeCondition("addStatusEnum", EntityOperator.EQUALS, "addStatusEnum_2"));
		andExprse.add(EntityCondition.makeCondition("thruDate", EntityOperator.EQUALS, null));
		andExprse.add(EntityCondition.makeCondition("partyClient", EntityOperator.EQUALS, inputFields.partyClient));
		andConds = EntityCondition.makeCondition(andExprse, EntityOperator.AND);
		//當前登錄人的我的好友（不再黑名單中的）
		LoginFriendsList = delegator.findList("MyFriends",andConds, UtilMisc.toSet("friendId"), null, null, true);//非我屏蔽的好友；
		andExprse = FastList.newInstance();
		
		if("appTypeEnum_0".equals(partyClient)){
			shieldingPartys = ParameterSettingServices.getShieldingParty(delegator,loginId,inputFields.partyClient);
			if(shieldingPartys)
				andExprse.add(EntityCondition.makeCondition("beConcernId", EntityOperator.NOT_IN, shieldingPartys));
		}
		andExprse.add(EntityCondition.makeCondition("partyId", EntityOperator.EQUALS, loginId));
		andExprse.add(EntityCondition.makeCondition("partyClient", EntityOperator.EQUALS, inputFields.partyClient));
		andExprse.add(EntityCondition.makeCondition("thruDate", EntityOperator.EQUALS, null));
		andConds = EntityCondition.makeCondition(andExprse, EntityOperator.AND);
		//我關注的人（不再黑名單中的）
		loginConcernList = delegator.findList("Concern",andConds, UtilMisc.toSet("beConcernId"), null, null, true);
		
		if(loginConcernList){
			beConcernIdList = EntityUtil.getFieldListFromEntityList(loginConcernList, "beConcernId", true);//非我屏蔽的我關注的人
			if(beConcernIdList){
				loginIds.addAll(beConcernIdList);
			}
		}
		if(LoginFriendsList){
			friendIdList = EntityUtil.getFieldListFromEntityList(LoginFriendsList, "friendId", true);
			if(friendIdList){
				loginIds.addAll(friendIdList);
			}
		}
		//我的好友和我關注的人（非黑名單中的）去重
		loginIds = new ArrayList(new HashSet(loginIds));
	

 loginIds是當前的登錄人的好友和關注列表

 

根據partyIdse來進行篩選 這個集合代表的共同好友集合。共同好友才會顯示 評論或贊

//loginIds是當前的登錄人的好友和關注列表  partyIds是當前醫生的好友和關注列表 對比 如果是好友相同的則顯示。

	for(int i=0;i<loginIds.size();i++){
		for(int j=0;j<partyIds.size();j++){
			if(loginIds[i]==partyIds[j]){
				partyIdse.add(partyIds[j]);
			}
		}
	}

最后得到兩個集合的數據並返回

//評論集合
		 
		 	andExprs = FastList.newInstance();
			andExprs.add(EntityCondition.makeCondition("caseHisTopId", EntityOperator.EQUALS, result.caseHisTopId));
			andExprs.add(EntityCondition.makeCondition("thruDate", EntityOperator.EQUALS, null));
			andExprs.add(EntityCondition.makeCondition("reviewTypeEnum", EntityOperator.EQUALS, "reviewTypeEnum_1"));
			andExprs.add(EntityCondition.makeCondition("partyId", EntityOperator.IN,partyIdse));
			andCond = EntityCondition.makeCondition(andExprs, EntityOperator.AND);
			
			
			Set set=["content","partyName","partyheadUrl","partyId","caseHisTopRevId","caseHisTopId","reviewTypeEnum","levelEnum","replyId","replyTopRevId"];
			
			reviewList = delegator.findList("CaseHisTopReviewAndParty",andCond,set, null, null, false);//非我屏蔽的好友；
			result.reviewList=org.extErp.sysCommon.util.JsonUtil.jsonFromGenericValueList(reviewList);
			//得到被回復人的信息
				if(result.reviewList){
					for(Map<String,Object> review:result.reviewList){
						if(review.replyId){
							gvList = delegator.findList("Party",EntityCondition.makeCondition("partyId", EntityOperator.EQUALS,review.replyId),UtilMisc.toSet("partyheadUrl","partyName"), null, null, true);
							if(gvList){
								gv =  EntityUtil.getFirst(gvList);
							}
							review.gv=gv;
						}
					}
			}
			//點贊集合
			andExprs = FastList.newInstance();
			andExprs.add(EntityCondition.makeCondition("caseHisTopId", EntityOperator.EQUALS, result.caseHisTopId));
			andExprs.add(EntityCondition.makeCondition("thruDate", EntityOperator.EQUALS, null));
			andExprs.add(EntityCondition.makeCondition("reviewTypeEnum", EntityOperator.EQUALS, "reviewTypeEnum_2"));
			andExprs.add(EntityCondition.makeCondition("partyId", EntityOperator.IN,partyIdse));
			andCond = EntityCondition.makeCondition(andExprs, EntityOperator.AND);
//			praiseList = delegator.findByAndCache("CaseHisTopReviewAndParty",["caseHisTopId":result.caseHisTopId,"thruDate":null,"reviewTypeEnum":"reviewTypeEnum_2"],null);
			praiseList = delegator.findList("CaseHisTopReviewAndParty",andCond, UtilMisc.toSet("content","partyName","partyheadUrl","partyId","caseHisTopRevId","caseHisTopId","reviewTypeEnum","levelEnum"), null, null, true);//非我屏蔽的好友；
			if(praiseList){
				result.praiseList=org.extErp.sysCommon.util.JsonUtil.jsonFromGenericValueList(praiseList);
			}
