Maven的作用是來(lái)管理項(xiàng)目依賴構(gòu)件（jar包）
1. 下載Maven
官方地址：http://maven.apache.org/download.cgi

2. 解壓并新建一個(gè)本地庫(kù)文件夾E:\MavenRepository
3.在settings.xml中配置本地倉(cāng)庫(kù)路徑及國(guó)內(nèi)鏡像服務(wù)器地址

Maven國(guó)內(nèi)鏡像倉(cāng)庫(kù)：

<localRepository>E:\MavenRepository</localRepository>

4.配置maven環(huán)境變量

6.新建Maven項(xiàng)目

這里maven會(huì)自動(dòng)下載需要的構(gòu)件，完成后項(xiàng)目目錄結(jié)構(gòu)如下圖

pom.xml報(bào)錯(cuò)原因是，因?yàn)閯?chuàng)建的是JavaEE工程，需要添加web.xml，在工程上右鍵

將對(duì)應(yīng)項(xiàng)目的文件可以拷貝到對(duì)應(yīng)的maven項(xiàng)目目錄下
7.配置pom.xml
