mybatis 自动生成代码

public static void main(String[] args) {
		Runtime r = Runtime.getRuntime();
		Process p = null;
		try {
			String s = "java -jar mybatis-generator-core-1.3.2.jar -configfile generator.xml -overwrite";
			p = r.exec(s);

			BufferedReader bufferedReader = new BufferedReader(
					new InputStreamReader(p.getInputStream()));
			String line = null;
			while ((line = bufferedReader.readLine()) != null) {
				System.out.println(line);
			}
		} catch (Exception e) {
			e.printStackTrace();
		}

		// System.out.println(System.getProperty("user.dir"));//user.dir指定了当前的路径
