在Eclipse中创建一个新的spring Boot项目：
1. 首先在Eclipse中安装STS插件：在Eclipse主窗口中点击 Help -> Eclipse Marketplace...
Search或选择“Popular”标签，选择Spring Tool 插件，Install：
2. 安装成功之后，会提示重启Eclipse工具，重启之后，New --> Project...
找到Spring Boot目录，选择Spring Starter Project，Next
3. 在New Spring Starter Project窗口，修改自己项目的配置，也可以直接使用默认信息，我这里是写一个demo工程，所以就使用了默认信息，Next
4. 在New Spring Starter Project Dependencies窗口，选择自己将会依赖哪些Jar包，点击Finash，创建完成
5. 新项目就创建完成,新项目就创建好了，各个目录如下：
6. 生成的pom文件内容如下：

7. 新建一个TestController类
@RestController
public class TestController { @RequestMapping("/hello1")
public String test(){
return "hello,this is a springboot demo";
} }
8. 在application.properties文件中设置tomcat端口号为8081
9. 右键DemoApplication中的main方法，Run As -> Spring Boot App，项目就可以启动了。
10. 项目启动成功
11. 页面访问：http://localhost:8081/hello1，成功
