SpringBoot

一个功能
浏览器发送hello请求，服务器接受请求并处理,响应Hello World字符串.
1.创建一个maven工程；(jar)
2.导入依赖Spring Boot相关的依赖

1	`参考：<a target="_blank">https://projects.spring.io/spring-boot/#quick-start</a>`

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.0.2.RELEASE</version>
</parent>
<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
</dependencies>

3.编写一个主程序；启动Spring Boot应用
4.编写相关Controller、Service

package hello;
 
import org.springframework.boot.*;
import org.springframework.boot.autoconfigure.*;
import org.springframework.stereotype.*;
import org.springframework.web.bind.annotation.*;
 
@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);
    }
}

5.运行主程序测试
6.简化部署

pox.xml配置

<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
        </plugin>
    </plugins>
</build>
