会社のプロジェクトを終わらせたばかりです.前に知っていたnodejsを実践してください.
必要なカバン/モジュールをインストールします.
1、 nodejs
2、 npm ---** **
3、 :
mysql---npm install [-g] node-mysql, npn install [-g] mysql
express---npm install [-g] express
jade---npm install [-g] jade[ ]
!
理解したnodejs基礎に基づいて、注意すべき点を並べます.1、 :---
var Dao = function () {
this.className = "Dao";
var mysql = require('mysql');
var pool = mysql.createPool({
host: 'localhost',
user: 'wenshuang3',
password: '13746.com',
database: 'cai',
port: 3306
});
this.pool = pool;//
this.insert = function (params) {
}; //
this.update = function (params) {
}; //
this.delete = function (params) {
}; //
this.select = function (params) {
}; //
};
module.exports = new Dao();
==================================
var dao = require('./Dao');
var UserDao = function() {
this.className = "UserDao";
};
UserDao.prototype = dao;
module.exports = new UserDao();
2、router
var express = require('express');
var router = express.Router();
var userService = require("../serv/service/impl/UserServiceImpl");
/* POST home page. */
router.post('/', function (req, res) {
var name = req.body.name;
var age = req.body.age;
var opt = req.body.type.toString();
console.log(name + "==" + age + "---" + opt);
console.log(typeof opt + "---" + typeof "select" + "==" + (opt == "select" ));
var send_data = {
name: name,
age: age,
callback: function (data) {
res.render('userinfo', data);
}
};
if (opt == "insert") {
console.log("insert...");
userService.insert(send_data);
} else if (opt == "update") {
console.log("update...");
userService.update(send_data);
} else if (opt == "delete") {
console.log("delete...");
userService.delete(send_data);
} else if (opt == "select") {
console.log("select...");
userService.select(send_data);
} else {
console.log("no opt...");
}
});
module.exports = router;

ここまでしばらく研究してみますが、これは基礎研究だけです.
