}

插入本地数据库：

fun insertChat(chatBean: ChatBean) : Long {var chatListLocal = getAllChat()if(chatListLocal == null || chatListLocal.size < 1){return WcDatabase.getInstance(WcApp.getContext()).chatDao().insertChat(chatBean)}var resultList = chatListLocal.filter {it.messageId.equals(chatBean.messageId)}//过滤重复数据if(resultList.size > 0){return 0}return WcDatabase.getInstance(WcApp.getContext()).chatDao().insertChat(chatBean)
}

接收红包：

if(content.startsWith(CommonUtils.Chat.REDPACKET_MARK)){//发送红包， 去掉redpacket###写入数据库content = CommonUtils.Chat.getRedpacket(content).toString()var chatBean = CommonUtils.Chat.getChatBean(fromUser, toUser, userType, content, ChatBean.CONTENT_TYPE_REDPACKET, "",0.0, 0.0)ChatRepository.insertChat(chatBean)chatBean.isReceive = trueEventBus.getDefault().post(chatBean)
