一键生成Spring MVC + MyBatis + maven项目

首先创建一个新的maven项目，在src/main/java创建一个类Test

然后在Test复制以下代码：

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;

    final static String database = "shop";   //数据库名称
    final static String user = "root";//数据库账号
    final static String password = "123456";//数据库密码
    //---------------^^^^^^^^^^^^^配置上面四项^^^^^^^^^^^^^^^^^--------------------------
    final static String dburl = "jdbc:mariadb://localhost:3306/"+database;  //服务器地址
    final static String dbdriver = "org.mariadb.jdbc.Driver"; //驱动
    public static void main(String[] args) throws Exception {
        System.out.println("1、第一次配置");
        System.out.println("2、第二次配置");
        System.out.print("请输入配置：");
        Scanner scanner = new Scanner(System.in);
        String c = scanner.next();
        if("1".equals(c)){
            System.out.println("开始第一次配置");
            createStart();
            System.out.println("开始第一次配置完成");
        }
        else if("2".equals(c)){
            System.out.println("开始第二次配置");
            for (String table : TBlist()) {
                createStart(tables(table));
            }
            //创建Request
            System.out.println("创建Request");
            createFile(new File(srcPackage + "util\Result.java"), createResult());
            System.out.println("开始第二次配置完成");
        }else{
            System.out.printf("只能输入1、2选项");
        }
    }

    //获取当前项目的路径
    public static String url = System.getProperty("user.dir");
    //包的路径

    private static String tablename;
    private String[] colnames; // 列名数组
    private String[] colTypes; // 列名类型数组
    private int[] colSizes; // 列名大小数组
    static void createStart() {
        System.out.println("开始配置pom.xml");
        System.out.println(configPomXml(url));
        url = url + File.separator + "src" + File.separator + "main";
        System.out.println("开始配置resources目录");
        createResources(url + File.separator + "resources");

注意：修改自己项目根目录的包名 以及使用数据库的使用账号密码和驱动等等

 下一步启动Main()方法：

 第一次配置成功后不要直接启动Main()方法，要去pom里面import相关的包再启动：输入2

第二次配置完成后，打开右边的Maven执行mybatis-generator:generate

 

执行完成后会有dao和实体出现

最后我们去配置Tomcat 完成后就直接可以编写代码

我们就搭建好了一个 ssm 的maven项目
