新建一个maven项目

 

pom.xml增加如下配置

       
      
       UTF-8
        
      
       1.8
        
      
       1.8
      
     
         
      
       org.springframework.boot
          
      
       spring-boot-starter-parent
          
      
       1.5.0.RELEASE
      
     
         
              
       
        org.springframework.boot
               
       
        spring-boot-starter-web
           
      
     
             
      
       ${project.artifactId}
              
                  
                   
                       
        
         org.apache.maven.plugins
                        
        
         maven-compiler-plugin
                        
                            
         1.8                    
         
          1.8
                             
         
          UTF-8
                         
                    
                   
                       
        
         org.springframework.boot
                        
        
         spring-boot-maven-plugin
                    
               
      
     

 

 

创建一个HelloController

package com.zns.controller;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.ResponseBody;@Controllerpublic class HelloController {    @RequestMapping("/hello")    @ResponseBody    public String hello() {        return "hello world";    }}

 

 

创建项目启动类Application

package com.zns;import org.springframework.boot.Banner;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;@SpringBootApplicationpublic class Application {    public static void main(String[] args) {        SpringApplication application = new SpringApplication(Application.class);        //设置启动时是否显示banner图        application.setBannerMode(Banner.Mode.OFF);        application.run(args);    }}

 

banner图可以在src/main/resources下新增banner.txt文件设置

 

src/main/resources下增加一个application.yml

server:  port: 8080  context-path: / # 访问地址：http://localhost:8080/

 

yml文件需注意冒号后面要有空格!

 

启动方式1：

在启动类文件右键 Run as Java application

浏览器访问http://localhost:8080/hello 

 

启动方式2：

 

利用springboot maven插件启动

确保pom.xml含有下面依赖

    	
     
      org.springframework.boot
     	
     
      spring-boot-maven-plugin
     
    

 

点击  Run Configurations,找到maven build,点击new,输入name

点击browse workspace选中要启动的项目

Goals处填写spring-boot:run 

点击apply和run即可
