话不多说，直接上代码吧

一个ssm框架的maven项目结构应该是这样的：

详细配置文件代码如下：

pom.xml

配置各种监听

    
      
     
      ssm_lzy
       
       
     	
     		
      
       contextConfigLocation

       dispatcherServlet
      		
      
       /
      	
     
    

springMVC配置文件

dispatcherServlet-servlet.xml

spring+mybatis配置文件（这里把他们一起整合了）

applicationContext.xml

数据库配置文件

dbconfig.properties

jdbc.driverClass=com.mysql.jdbc.Driverjdbc.jdbcUrl=jdbc:mysql://localhost:3306/misis?serverTimezone=GMT&useSSL=falsejdbc.user=rootjdbc.password=790115

mybatis配置文件

mybatis-config.xml

mybatis generator配置文件

mbg.xml

启动逆向生成代码

TestMbg.java

package com.lzy.test;import java.io.File;import java.util.ArrayList;import java.util.List;import org.mybatis.generator.api.MyBatisGenerator;import org.mybatis.generator.config.Configuration;import org.mybatis.generator.config.xml.ConfigurationParser;import org.mybatis.generator.internal.DefaultShellCallback;public class TestMbg {	public static void main(String[] args) throws Exception{		System.out.println("start...");		List
    
      warnings = new ArrayList
     
      ();		   boolean overwrite = true;		   File configFile = new File("mbg.xml");		   ConfigurationParser cp = new ConfigurationParser(warnings);		   Configuration config = cp.parseConfiguration(configFile);		   DefaultShellCallback callback = new DefaultShellCallback(overwrite);		   MyBatisGenerator myBatisGenerator = new MyBatisGenerator(config, callback, warnings);		   myBatisGenerator.generate(null);		   System.out.println("successful...");	}}
     
    

本次示例：

jdk 1.8.0_161

tomcat v8.5
