  • Mybatis逆向工程的使用。

    指定配置文件与main运行生成

    public class GeneratorSqlmap {
     
        public void generator() throws Exception {
            List<String> warnings = new ArrayList<String>();
            boolean overwrite = true;
            // 指定配置文件
            File configFile = new File("E:\Code\ThreeDay03/src/com/aa/utils/generatorConfig.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);
        }
     
        // 执行main方法以生成代码
        public static void main(String[] args) {
            try {
                GeneratorSqlmap generatorSqlmap = new GeneratorSqlmap();
                generatorSqlmap.generator();
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    
    }
