使用IDEA 创建Maven项目，外加SSM框架

使用idea 新创建项目

然后 新创建 java 、resources 文件夹......

图上是项目结构

java文件夹下的 文件夹 命名规范 com.nf147（组织名）+ oukele（作者）

然后将 自动生成类 放入 其中 ，运行 ，按照步骤进行操作

每操作完成一步 都需要 刷新一下 maven项目 如：

generatorConfig.xml 文件生成完后 ，刷新maven项目，然后双击红色箭头处后，自动生成 entity dao mapper

自动生成类：

package com.nf147.oukele;

import java.io.*;
import java.sql.Connection;
import java.sql.DatabaseMetaData;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.util.ArrayList;
import java.util.List;
import java.util.Scanner;
