1.Maven技术 · JavaWeb项目开发学习手册

**Maven** **我为什么要学习这个技术？** 1.在Javaweb开发中，需要使用大量的jar包，我们手动去导入； 2.如何能够让一个东西自动帮我导入和配置这个jar包。由此，Maven诞生了！ **1.1 Maven** **项目架构管理工具** 我们目前用来就是方便导入jar包的！ Maven的核心思想：**约定大于配置** ** ![](file:///C:\Users\mac\AppData\Local\Temp\ksohtml7968\wps1.png)有约束，不要去违反。 Maven会规定好你该如何去编写我们的Java代码，必须要按照这个规范来； **1.2** **下载安装****Maven** 官网;[https://maven.apache.org/](https://maven.apache.org/) 下载完成后，解压即可；友情建议：电脑上的所有环境都放在一个文件夹下，方便管理； **1.3** **配置环境变量** 在我们的系统环境变量中配置如下配置： M2\_HOMEmaven目录下的bin目录MAVEN\_HOMEmaven的目录在系统的path中配置%MAVEN\_HOME%\\bin 测试Maven是否安装成功，保证必须配置完毕！ **1.4** **阿里云镜像** ** ![](file:///C:\Users\mac\AppData\Local\Temp\ksohtml7968\wps2.png)镜像：mirrors 作用：加速我们的下载国内建议使用阿里云的镜像 1 2nexus-aliyun 3\*,!jeecg,!jeecg-snapshots 4Nexus aliyun 5http://maven.aliyun.com/nexus/content/groups/public 6 **1.5** **本地仓库** 在本地的仓库，远程仓库； **建立一个本地仓库：**localRepository 1D:\\Environment\\apache-maven-3.6.2\\maven- repo **1.6****、在****IDEA****中使用****Maven** 1.启动IDEA 2.创建一个MavenWeb项目 ![](file:///C:\Users\mac\AppData\Local\Temp\ksohtml7968\wps3.png)3.等待项目初始化完毕 ![](file:///C:\Users\mac\AppData\Local\Temp\ksohtml7968\wps4.png)4.观察maven仓库中多了什么东西？ 5.IDEA中的Maven设置注意：IDEA项目创建成功后，看一眼Maven的配置 ![](file:///C:\Users\mac\AppData\Local\Temp\ksohtml7968\wps5.png)6.到这里，Maven在IDEA中的配置和使用就OK了! **1.7****、创建一个普通的****Maven****项目** ** ![](file:///C:\Users\mac\AppData\Local\Temp\ksohtml7968\wps6.png)这个只有在Web应用下才会有！ **1.8** **标记文件夹功能** ** ![](file:///C:\Users\mac\AppData\Local\Temp\ksohtml7968\wps7.png) ![](file:///C:\Users\mac\AppData\Local\Temp\ksohtml7968\wps8.png) **1.9** **在****IDEA****中配置****Tomcat** ![](file:///C:\Users\mac\AppData\Local\Temp\ksohtml7968\wps9.png) ![](file:///C:\Users\mac\AppData\Local\Temp\ksohtml7968\wps10.png)解决警告问题必须要的配置：**为什么会有这个问题：我们访问一个网站，需要指定一个文件夹名字；** ** ![](file:///C:\Users\mac\AppData\Local\Temp\ksohtml7968\wps11.png) **1.10** **pom** **文件** pom.xml是Maven的核心配置文件 ![](file:///C:\Users\mac\AppData\Local\Temp\ksohtml7968\wps12.png)1 2 3 4<project xmlns\="http://maven.apache.org/POM/4.0.0" xmlns:xsi\="http://www.w3.org/2001/XMLSchema-instance" 5xsi:schemaLocation\="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"\> 64.0.0 7 8 9com.kuang 10javaweb-01-maven 111.0-SNAPSHOT 12 16war 17 18 19 20 21 22UTF-8 23 241.8 251.8 26 27 28 29 30 31 32junit 33junit 344.11 35 36 37 <table class="MsoNormalTable" border="0" cellspacing="0" style="border-collapse:collapse;margin-left:5.4000pt;border:none;
