简单的例子
本例子基于maven构建 新建maven项目,修改其pom文件

开始写代码
@SpringBootApplication
public class SpringBootDemoApplication {
@RequestMapping("/hello")
public String say(){
return "Spring Boot 你大爷!";
}
public static void main(String[] args) {
SpringApplication.run(SpringBootDemoApplication.class, args);
}
}
启动项目,直接运行main方法
启动成功 访问 http://localhost:8080
该项目是基于springboot partent构建的
很多时候spring-boot-starter-parent
包含了大量配置好的依赖管理,在自己项目添加这些依赖的时候不需要写版本号
使用父pom虽然简单,但是有些情况我们已经有父pom,不能直接增加时,可以通过如下方式:
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
