SpringBoot并不是对Spring功能上的一种增强,而是提供了一种快速使用spring的一种方式。开箱即用,没有代码生成,也无需 XML 配置
Maven + Spring Web 项目结构在 Eclipse 下面的实现
在 POM.XML中添加,父工程依赖,springWeb工程依赖,springBoot Maven运行编译环境
添加后在编写JAVA代码
测试就直接main方法启动,如下就启动成功了,在浏览器输入测试的话就是:http://localhost:8080/springboot/l
4000
istindex。根据你自己写的路径就好了。
@EnableAutoConfiguration为springboot程序入口,一个程序就一个入口,所以可以把他单独的拿出来。
