插入本地数据库：

fun insertChat(chatBean: ChatBean) : Long {
    var chatListLocal = getAllChat()

        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 = true
    EventBus.getDefault().post(chatBean)
}
