    List<String> warnings = new ArrayList<String>();
    boolean overwrite = true;
    //指向逆向工程配置文件
    File configFile = new File("src/main/resources/mybatis-generator.xml");

    Configuration config = cp.parseConfiguration(configFile);
    DefaultShellCallback callback = new DefaultShellCallback(overwrite);
    MyBatisGenerator myBatisGenerator =
    new MyBatisGenerator(config, callback, warnings);
    myBatisGenerator.generate(null);
