一.基本信息

     源码仓库：https://github.com/spring-projects/spring-boot

     帮助文档：https://spring.io/guides/gs/spring-boot/

二.快速开始

      1.通过maven创建一个工程

mvn archetype:generate -DgroupId=com.hippo -DartifactId=AppDemo -DarchetypeArtifactId=maven-archetype-webapp

    2.创建一个package包目录

      mkdir -p src/main/java/hello

    3.配置一下pom.xml

    
        
     
      4.0.0
         
     
      com.hippo
         
     
      AppDemo
         
     
      0.1.0
         
             
      
       org.springframework.boot
              
      
       spring-boot-starter-parent
              
      
       1.5.8.RELEASE
          
         
             
                  
       
        org.springframework.boot
                   
       
        spring-boot-starter-web
               
          
         
             
      
       1.8
          
         
             
                  
                       
        
         org.springframework.boot
                        
        
         spring-boot-maven-plugin
                    
               
          
     
    

4.创建一个contrller文件

   touch src/main/java/hello/HelloController.java

package hello;import org.springframework.web.bind.annotation.RestController;import org.springframework.web.bind.annotation.RequestMapping;@RestControllerpublic class HelloController {    @RequestMapping("/")    public String index() {        return "Greetings from Spring Boot!";    }}

  5. 创建一个Application 启动文件

   touch src/main/java/hello/Application.java

package hello;import java.util.Arrays;import org.springframework.boot.CommandLineRunner;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;import org.springframework.context.ApplicationContext;import org.springframework.context.annotation.Bean;@SpringBootApplicationpublic class Application {    public static void main(String[] args) {        SpringApplication.run(Application.class, args);    } }

 6.启动

mvn package && java -jar target/AppDemo.jar

7.访问

$ curl localhost:8080Greetings from Spring Boot!
