Spring boot学习笔记

一、Spring Boot入门

1、Spring Boot简介

简化Spring应用开发的一个框架；（集成starter，约定大于配置）
整个Spring技术栈的一个大整合；
J2EE开发的一站式解决方案。

2、Spring Boot特性

1. 为spring 的开发提供更快的入门体验
2. 开箱即用，没有代码生成，也无需xml配置。同事也可以修改默认值来满足特定的需求。
3. 提供了一些大型项目中常见的非功能性特性。如嵌入式服务器、安全、指标，健康检测、外部配置等。
4. Spring Boot并不是对spring功能上的增强，而是提供了一种快速使用 Spring 的方式。

3、Spring Boot引导类

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

注： @SpringBootApplication 其实就是以下三个注解的总和：

@Configuration：用于定义一个配置类
@EnableAutoConfiguration：Spring Boot会根据你jar包的依赖来自动配置项目
@ComponentScan：告诉 Spring 哪个包下的用注解标识的类会被 Spring 自动扫描并且装入 bean 容器。
