1 新建專案

2 定義專案資訊

3 選擇所需模組

4 專案結構

4.1 resources資料夾中目錄結構

• static：儲存所有的靜態資源； js css images
• templates：儲存所有的模板頁面；（Spring Boot預設jar包使用嵌入式的Tomcat，預設不支援JSP頁面）；可以使用模板引擎（freemarker、thymeleaf）
• application.properties：Spring Boot應用的全域性配置檔案；可以修改一些預設設定

5 預設pom

6 啟動類

@SpringBootApplication
public class Application {

	public static void main(String[] args) {
		SpringApplication.run(Application.class, args);
	}
}

7 新建Controller

@RestController
public class HelloController {
    @RequestMapping("hello")
    public String hello() {
        return "hello world！";
    }
}

8 測試

http://localhost:8080/hello
