Log4j JPA Appender(Log4j JPA Appender)

 你可以看看Sequelize 。 从主页使用的示例（我添加了与Code First相关的注释）： 
 
var Sequelize = require('sequelize');
// define your "context"
var sequelize = new Sequelize('database', 'username', 'password');

// define your "entities"
var User = sequelize.define('user', {
  username: Sequelize.STRING,
  birthday: Sequelize.DATE
});

// use them
sequelize.sync().then(function() {
  return User.create({
    username: 'janedoe',
    birthday: new Date(1980, 6, 20)
  });
}).then(function(jane) {
  console.log(jane.get({
    plain: true
  }));
});

You can look into Sequelize. Example of usage from the home page (I added comments to relate to Code First):
 
var Sequelize = require('sequelize');
// define your "context"
var sequelize = new Sequelize('database', 'username', 'password');

// define your "entities"
var User = sequelize.define('user', {
  username: Sequelize.STRING,
  birthday: Sequelize.DATE
});

// use them
sequelize.sync().then(function() {
  return User.create({
    username: 'janedoe',
    birthday: new Date(1980, 6, 20)
  });
}).then(function(jane) {
  console.log(jane.get({
    plain: true
  }));
});
