1.新建maven項目css

2.選擇webapphtml

3.如果項目沒有 src/main/java 則在下圖中新建main下新建java文件夾java

4.在 src/main/java 文件夾下新建 cn.com.test 包mysql

5.右鍵 properties => project facets 發現 dynamic web module 是 2.3 而且沒法修改web

6.到項目根目錄，修改下圖文件，jst.web 2.3 改成 3.0spring

7.修改 pom.xmlsql

8.更新maven架包數據庫

8.右鍵 properties => deployment assembly 添加express

9.在 src/main/resources 添加配置文件apache
