一.在 idea 中使用 mybatis generator 逆向工程

1.在IDEA上创建maven工程。

2.在pom.xml中配置MyBatis逆向工程插件

           
             
      
       org.mybatis.generator
              
      
       mybatis-generator-maven-plugin
              
      
       1.3.5
              
                
       
        true
                 
       
        true
               
            
     

3..配置generatorConfig.xml；

 4.执行Java 类

package com.yp.manager;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;import java.io.File;import java.util.ArrayList;import java.util.List;/** * desc * * @Author 袁朋 * @Date 2019/3/5 */public class Generator {    public void generator() throws Exception{        List
     
       warnings = new ArrayList
      
       ();        boolean overwrite = true;        /**指向逆向工程配置文件*/        File configFile = new File("/Users/mryuan/IdeaProjects/creditRouter-tyr/onlineShop/onlineShop-mybatis-generator/src/main/resources/generationConfig.xml");        ConfigurationParser parser = new ConfigurationParser(warnings);        Configuration config = parser.parseConfiguration(configFile);        DefaultShellCallback callback = new DefaultShellCallback(overwrite);        MyBatisGenerator myBatisGenerator = new MyBatisGenerator(config,                callback, warnings);        myBatisGenerator.generate(null);    }    public static void main(String[] args) throws Exception {        try {            Generator generatorSqlmap = new Generator();            generatorSqlmap.generator();        } catch (Exception e) {            e.printStackTrace();        }    }}
