为了统一处理，ThinkJS 提供了 init 方法来代替 constrcutor 方法，该方法不管是在 class 下还 是动态创建类的情况下都可以做到类实例化的时候自动被调用。 export default class think.base { /** * 初始化⽅方法，类实例例化时⾃自动被调⽤用 * @return {} [] */ init(){ ... } await model.select(); return this.success(data); } }); init 方法 ES6 里的 class 有 contructor 方法，但动态创建的类就没有该方法了，为了统一初始化执行的方 法，将该方法统一定义为 init 。 该方法在类实例化的时候自动调用，无需手工调用。 ES6 方式 ```js 'use strict'; class extends Base { init(http){ super.init(http); //调用父类的init方法 ... } } ``` 动态创建类方式 'use strict'; var Base = require('./base.js'); module.exports = think.controller(Base, { init: function(http){

if you are not using ES6’s class grammar, you should not use constructor method. ThinkJS provide init method to replace constructor . It will called automatically whether you using class or not. Tips: think.base { /** * Initial method, called when class instanced * @return {} [] */ init(){ ... } } JavaScript Compile by Babel Replace */yield with async/await Upgrading Guide dynamically created do not, in order to perform the initialization uniformly, ThinkJS redefined it as init . This method is automatically called when the class is instantiated, without manually call needed

WicketFilter <init-param> applicationClassName org.wicketTutorial.WicketApplication init-param> specifies which page to use as a homepage for our application. Another important method is init(): protected void init() 9 This method is called when our application is loaded by the web server (Tomcat, void init() { super.init(); // add your configuration here } } Since this is a very basic example of a Wicket application, we don’t need to specify anything inside the init method
