1. SpringBoot介紹

(1) 什么是Spring Boot？

(2) Spring Boot有哪些特點？

Spring Boot 設(shè)計目的是用來簡化新 Spring 應(yīng)用的初始搭建以及開發(fā)過程。

嵌入的 Tomcat，無需部署 WAR 文件

Spring Boot 并不是對 Spring 功能上的增強，而是提供了一種快速使用 Spring 的方式。

2. 構(gòu)建SpringBoot項目以及啟動器講解

(1) Spring Boot常見的啟動器有哪些？

所謂的SpringBoot啟動器其實就是一些jar包的集合。SpringBoot一共提供44啟動器。

spring-boot-starter-web 支持全棧式的web開發(fā)，包括了tomcat和springMVC等jar

Spring-boot-starter-jdbc 支持spring以jdbc方式操作數(shù)據(jù)的jar包的集合。

Spring-boot-starter-redis 支持redis鍵值存儲的數(shù)據(jù)庫操作。

(2) Spring Boot的Web啟動器的坐標(biāo)是什么？

<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency>

3. 編寫HelloWorld

(1) 如何編寫Spring Boot啟動類？

package com.bjsxt;import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; /*** SpringBoot 啟動類* @author MSI-PC**/ @SpringBootApplication public class App {public static void main(String[] args) {SpringApplication.run(App.class, args);} }

(2) 編寫Spring Boot啟動類時需要注意什么？

啟動器存放的位置，啟動器可以和controller位于同一個包下，或者位于controller的上一級包中，但是不能放到controller平行的包及子包下。即啟動器只能位于Controller所在包及其上級包中。
