一、项目功能概述
电商秒杀需要完成的3个功能：
1.展示一个商品列表页面，我们可以从中看到可秒杀的商品列表
2.点击进入商品详情页，获取该商品的详细信息
3.秒杀时间开始后，点击进入下单确认页面，并支付成功
二、基于SpringBoot进行项目环境搭建
步骤1：创建一个maven工程，使用quickStart骨架。
步骤2：在pom.xml导入SpringBoot相关依赖。
1 <?xml version="1.0" encoding="UTF-8"?> 2 3 <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 4 xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> 5 <modelVersion>4.0.0</modelVersion> 6 7 <groupId>org.example</groupId> 8 <artifactId>Spike</artifactId> 9 <version>1.0-SNAPSHOT</version> 10 11 <name>Spike</name> 12 <!-- FIXME change it to the project‘s website --> 13 <url>http://www.example.com</url> 14 15 <parent> 16 <groupId>org.springframework.boot</groupId> 17 <artifactId>spring-boot-starter-parent</artifactId> 18 <version>2.0.5.RELEASE</version> 19 </parent> 20 21 <properties> 22 <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> 23 <maven.compiler.source>1.8</maven.compiler.source> 24 <maven.compiler.target>1.8</maven.compiler.target> 25 </properties> 26 27 <dependencies> 28 <dependency> 29 <groupId>org.springframework.boot</groupId> 30 <artifactId>spring-boot-starter-web</artifactId> 31 </dependency> 32 <dependency> 33 <groupId>junit</groupId> 34 <artifactId>junit</artifactId> 35 <version>4.11</version> 36 <scope>test</scope> 37 </dependency> 38 </dependencies> 39 40 <build> 41 <pluginManagement><!-- lock down plugins versions to avoid using Maven defaults (may be moved to parent pom) --> 42 <plugins> 43 <!-- clean lifecycle, see https://maven.apache.org/ref/current/maven-core/lifecycles.html#clean_Lifecycle --> 44 <plugin> 45 <artifactId>maven-clean-plugin</artifactId> 46 <version>3.1.0</version> 47 </plugin> 48 <!-- default lifecycle, jar packaging: see https://maven.apache.org/ref/current/maven-core/default-bindings.html#Plugin_bindings_for_jar_packaging --> 49 <plugin> 50 <artifactId>maven-resources-plugin</artifactId> 51 <version>3.0.2</version> 52 </plugin> 53 <plugin> 54 <artifactId>maven-compiler-plugin</artifactId> 55 <version>3.8.0</version> 56 </plugin> 57 <plugin> 58 <artifactId>maven-surefire-plugin</artifactId> 59 <version>2.22.1</version> 60 </plugin> 61 <plugin> 62 <artifactId>maven-jar-plugin</artifactId> 63 <version>3.0.2</version> 64 </plugin> 65 <plugin> 66 <artifactId>maven-install-plugin</artifactId> 67 <version>2.5.2</version> 68 </plugin> 69 <plugin> 70 <artifactId>maven-deploy-plugin</artifactId> 71 <version>2.8.2</version> 72 </plugin> 73 <!-- site lifecycle, see https://maven.apache.org/ref/current/maven-core/lifecycles.html#site_Lifecycle --> 74 <plugin> 75 <artifactId>maven-site-plugin</artifactId> 76 <version>3.7.1</version> 77 </plugin> 78 <plugin> 79 <artifactId>maven-project-info-reports-plugin</artifactId> 80 <version>3.0.0</version> 81 </plugin> 82 </plugins> 83 </pluginManagement> 84 </build> 85 </project>
步骤3：在main/java/app中，我们对SpringBoot和SpringMVC进行简单的配置工作。掌握这几个注解的作用。
1 package org.example; 2 3 import org.springframework.boot.SpringApplication; 4 import org.springframework.boot.autoconfigure.EnableAutoConfiguration; 5 import org.springframework.web.bind.annotation.RequestMapping; 6 import org.springframework.web.bind.annotation.RestController; 7 8 //SpringBoot会帮我们启动tomcat，并加载默认配置 9 @EnableAutoConfiguration 10 //SpringMVC相关配置 11 @RestController 12 public class App { 13 @RequestMapping("/") 14 public String home(){ 15 //网页中输出 16 return "Hello World!"; 17 } 18 public static void main( String[] args ){ 19 //控制台输出 20 System.out.println( "Hello World!" ); 21 SpringApplication.run(App.class,args); 22 } 23 }
运行结果：
用浏览器打开http://localhost:8080/，我们可以看到页面上输出：Hello World！
同时，控制台也输出了Hello World！，以及一些Spring相关的信息。
