微框架 - spring boot快速入门

每次搭建项目可能是最浪费时间的一个环节，不管你是想做个什么东西，特别是要发布web环境，即使你讲tomcat或者jetty都集成在maven中，这一套下来可能在你脑海里划过的一些思绪早已无影无踪。今天发现了一个好用的spring的“微框架”:
Spring Boot。

Spring Boot是由Pivotal团队提供的全新框架，其设计目的是用来简化新Spring应用的初始搭建以及开发过程。该框架使用了特定的方式来进行配置，从而使开发人员不再需要定义样板化的配置。

看一下搭建这么一个web环境的过程：

1.配置maven：

<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
<version>1.0.2.RELEASE</version>
</dependency>

2.发布一个微服务：

packa
4000
ge com.tiger.springboot;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;
@Controller
@EnableAutoConfiguration
public class SimpleController {
@RequestMapping(value ="/hello", method = RequestMethod.GET)
@ResponseBody
public String hello(){
return "hello world";
}
public static void main(String[] args) {
SpringApplication.run(SimpleController.class, args);
}
}

然后就没有然后了，启动服务就可以通过浏览器访问项目了。

从这个大logo看的出spring boot这帮大神玩得还是挺开心的.其实是通过tomcat的8080端口发布的，但是这些你现在都不必去关心了。至于tomcat的一些高级配置还没有去研究，如ssl证书一类的，可能应该可以支持吧。不过到目前为止用这一套开做一些demo或者模块的快速开发应该是很不错的。
