Eclipse中創建一個新的SpringBoot項目

在Eclipse中創建一個新的spring Boot項目：

1. 首先在Eclipse中安裝STS插件：在Eclipse主窗口中點擊 Help -> Eclipse Marketplace...

Search或選擇“Popular”標簽，選擇Spring Tool 插件，Install：

2. 安裝成功之后，會提示重啟Eclipse工具，重啟之后，New --> Project...

找到Spring Boot目錄，選擇Spring Starter Project，Next

3. 在New Spring Starter Project窗口，修改自己項目的配置，也可以直接使用默認信息，我這里是寫一個demo工程，所以就使用了默認信息，Next

4. 在New Spring Starter Project Dependencies窗口，選擇自己將會依賴哪些Jar包，點擊Finash，創建完成

5. 新項目就創建完成,新項目就創建好了，各個目錄如下：

6. 生成的pom文件內容如下：

            </plugin>
        </plugins>
    </build>


</project>

7. 新建一個TestController類

@RestController
public class TestController {

    @RequestMapping("/hello1")
    public String test(){
        return "hello,this is a springboot demo";  
    }

}

8. 在application.properties文件中設置tomcat端口號為8081

9. 右鍵DemoApplication中的main方法，Run As -> Spring Boot App，項目就可以啟動了。

10. 項目啟動成功

11. 頁面訪問：http://localhost:8081/hello1，成功
