执行程序

package com.tian.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 GeneratorTest {

    public static void main(String[] args) throws Exception{
    Listwarnings=new ArrayList<>();
    //1、获取配置文件
    Configuration configuration=new ConfigurationParser(warnings).
            parseConfiguration(new File("src/main/resources/generatorConfig.xml"));
    //2、创建回调接口的实现类
    DefaultShellCallback callback=new DefaultShellCallback(true);
    //3、创建生成器对象
    MyBatisGenerator generator=new MyBatisGenerator(configuration, callback, warnings);
    //4、生成
    generator.generate(null);
}
