spring-boot 博客 : https://1769974308.github.io/blog/frame/springboot/build-springboot-project.html

一、环境

• jdk1.8

• maven

• intellij idea

二、创建项目

1、file->new->project

2、选择spring initializr

spring initializr是官方的构建插件，也可以选择maven

3、填写项目基本信息

group:组织id,一般分为多个段 com.taotaojava artifact：唯一标识符，项目名称

4、选择包

spring initializr提供很多选项，当前只选择web-web

三、目录结构

- src
    -main
        -java
            -package
                #主函数，启动类，运行它如果运行了 Tomcat、Jetty、Undertow 等容器
                -SpringbootApplication
        -resouces
            #存放静态资源 js/css/images 等
            - statics
            #存放 html 模板文件
            - templates
            #主要的配置文件，SpringBoot启动时候会自动加载application.yml/application.properties
            - application.yml
    #测试文件存放目录
    -test
 # pom.xml 文件是Maven构建的基础，里面包含了我们所依赖JAR和Plugin的信息
- pom

四、pom.xml 依赖

<?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">

    <build>
        <plugins>
            <!-- 编译插件 -->
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>

</project>

五、运行

主函数->run debug
