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(); } } }
