SpringBoot入门程序开发

● SpringBoot是由Pivotal团队提供的全新框架，其设计目的是用来简化Spring应用的初始搭建以及开发过程

1.创建新模块，选择Spring Initializr，并配置模块相关基础信息

2.选择当前模块需要使用的技术集3.开发控制器类

//rest模式
@RestController
@RequestMapping("/books")
public class Controller {
    @GetMapping
    public String getById(){
        System.out.println("springboot is running");
        return "springboot is running";
    }
}

4.运行自动生成的Application类

● 最简SpringBoot程序所包含的基础文件

  ◆ pom.xml文件

◆ Application类

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