坑了。。。

这篇blog已经不打算填坑了,一来以后不太会用spring-boot,二来坑填的也没啥意义,所以就这样吧。

Overview

搞Java那还是在5年前上大学的时候,那个时候spring印象中还是2.x,那个时候用spring还要写一大堆的xml配置,简直蛋疼无比。用Java做web开发也是各种蛋疼,还有各种框架,除了spring还有structs/hibernate/ibatis等等。
因为团队都是做Java的,而且前段时间也接手了几个SpringMVC的模块,才知道Spring已经进入了4.x的时代了,而且也有了很大改变,更适合于现代互联网web开发了,也不用写什么xml了。所以准备找时间重新学习一下spring4,而且spring.io新推出了一个叫做spring-boot的“微框架”,更适合于做快速web开发。

基本

尽管spring-boot还支持除了maven以外的一些构建工具,但是然并卵,生产管理还是用maven的居多,graddle有空可以看看。如果不想用<parent>引入相关依赖,也可以用以下配置:

import org.springframework.boot.*;
import org.springframework.boot.autoconfigure.*;
import org.springframework.stereotype.*;
import org.springframework.web.bind.annotation.*;
@RestController
@EnableAutoConfiguration
public class Example {
@RequestMapping("/")
String home() {
return "Hello World!";
}
public static void main(String[] args) throws Exception {
SpringApplication.run(Example.class, args);
}
}

在Java1.6时代,annotation其实并没有多大用处,但是在spring-boot中,几乎到处都是annotation。annotation本身有不少好处,可以增强代码复用,并且可以让代码可读性更好。

@RestController@RequestMapping

前者用于标注一个类是controller类,可以辅助生成一些功能。而后者是用来标注rest对应的path的。
