Dao接口、实体类、sql都已经生成好了，我们只需要编写Service、Controller即可！

1. 编写Controller

    @RequestMapping("/")
    fun selectMessageList(pageNum: Int?,type: Int?,model: ModelMap): String {
        var pageNum = pageNum?:1
        var type = type?:1
        var pageSize = 10
        PageHelper.startPage<Any>(pageNum, pageSize)
        var para = HashMap<Any,Any>()
        if (type==1){
            para.put("sorts","time")
        }else{
            para.put("sorts","praise")
        }
        var messageList = messageMapper!!.selectListByMap(para)
        var pageInfo = PageInfo(messageList)
        model.put("type",type)
        model.put("page",pageInfo)
        return "/msg"
    }


    @RequestMapping("/addMessage.json")
    @ResponseBody
    fun addMessage(nick_name: String, content: String, face: String):R {
        return messageService!!.addMessage(nick_name, content, face)
    }

2. 编写Service代码

    @Autowired
    private val messageMapper: MessageMapper? = null

    @Transactional
    fun addMessage(nick_name: String, content: String, face: String): R{
        var msg = Message()
        msg.nick_name = nick_name
        msg.content = content
        msg.face = face
        msg.add_time = Date()
        messageMapper!!.insertSelective(msg)
        return R(1,"")
    }
