一、简述一下spring-boot微框架
1、spring-boot微框架是什么？
大家都知道，在使用spring框架进行应用开发时需要很多*.xml的初始化配置文件，而springBoot就是用来简化新的Spring应用的初始搭建以及开发过程的微框架。该框架使用了自动设置的方式来进行配置，使开发人员不再需要定义样板化的配置，该框架可以方便前端开发任玥或者测试人员进行快速开发或者测试单元
2、spring官方介绍
官方springboot教程：http://projects.spring.io/spring-boot/
二、spring-boot快速开发
1、依赖包引用
在这里个人使用spring-boot1.3.5，采用maven环境搭建
我的maven依赖：
<!-- Inherit defaults from Spring Boot -->
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.3.5.RELEASE</version>
</parent>
<!-- Add typical dependencies for a web application -->
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
</dependencies>
<repositories>
<repository>
<id>spring-snapshots</id>
<url>http://repo.spring.io/libs-snapshot</url>
</repository>
</repositories>
<pluginRepositories>
<pluginRepository>
<id>spring-snapshots</id>
<url>http://repo.spring.io/libs-snapshot</url>
</pluginRepository>
</pluginRepositories>
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
2、快速开发
简单开发发布一个helloworld!应用
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.context.annotation.Configuration;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
@Configuration
@EnableAutoConfiguration
@Controller
public class TestController {
@RequestMapping("/hello")
@ResponseBody
public String hello()
{
return "helloworld!";
}
public static void main(String[] args) {
SpringApplication.run(TestController.class,args);
}
}
3、发布应用
如上代码，使用main()方法默认采用内置tomcat发布该应用，当然也可以使用其他内置容器或者外置容器
发布之后效果（看到这里，一个基于springBoot微框架的应用就开发完了，可以在浏览器打开http://localhost:8080/hello打开发布的应用）：
