- 1.通过IDEA或者Eclipse的spring Initialize创建   在src/main\com.example.demo编写controller ~~~ @Controller public class HelloController { @RequestMapping("/hello") @ResponseBody public String helloPage(){ return "hello springboot"; } } ~~~ - 2.访问http://start.spring.io/创建springboot的骨架   然后通过import导入到IDEA中  - 3.自己手动搭建    1.配置pom文件 ~~~ //pom.xml <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.1.1.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent> <properties> <java.version>1.8</java.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> </dependencies> ~~~ 2.编写控制器Controller ~~~ @Controller public class HelloController { @RequestMapping("/hello") @ResponseBody public String helloPage(){ return "Spring3"; } } ~~~ 3.编写配置类 ~~~ //AppConfig类 @SpringBootApplication public class AppConfig { public static void main(String[] args) { SpringApplication.run(AppConfig.class,args); } } ~~~ 4.运行main方法，浏览器访问：http://localhost:8080/hello
