@: es6新增的装饰器语法，babel已支持需要安装 babel-plugin-transform-decorators-legacy
类的静态属性：es7新增的语法，babel已支持需要安装 babel-preset-stage-2
@observer: 让 React 组件自动起来，它会自动更新，即便是在一个很大的程序里也会工作的很好
@observable：监听数据，当数据发生改变的时候自动刷新视图
@computed: 创建自动运算的表达式。（一般用于计算）
@action：改变了@observable创建的数据，需要装饰action方法！（需要配合'use strict'使用，有助于更好地构建代码）(可以不适用action,但是不建议这样做)
autorun: 当@observable创建的数据发生改变时自动执行
