spring Boot 分享(1)---hello world

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。通过这种方式，Spring Boot致力于在蓬勃发展的快速应用开发领域(rapid application development)成为领导者。

Spring Boot特点

编辑

1. 创建独立的Spring应用程序

2. 嵌入的Tomcat，无需部署WAR文件

3. 简化Maven配置

4. 自动配置Spring

5. 提供生产就绪型功能，如指标，健康检查和外部配置

6. 绝对没有代码生成和对XML没有要求配置

 

MVN的配置文件如下：

SampleController的代码如下：

package com.nuaa;

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.ResponseBody;

/**
 * Created by wangjiuyong on 2017/8/22.
 */
@Controller
@EnableAutoConfiguration
public class SampleController {

    @RequestMapping("/")
    @ResponseBody
    String home() {
        return "Hello World!";

    }

    public static void main(String[] args) throws Exception {
        SpringApplication.run(SampleController.class, args);
    }
}

 

用mvn install命令生成jar包后，运行java -jar ***.jar命令，就可以启动SpringBoot的服务了。
