使用runtime类执行dos命令并且解析输出结果

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.util.regex.Matcher;
import java.util.regex.Pattern;

public class Test {

	private static final Pattern p = Pattern
			.compile("(UU|D|U|_U)//s+(//S+?//.jsp)");

	/**
	 * @param args
	 */
	public static void main(String[] args) throws Exception {
		Process process = Runtime.getRuntime().exec(
				"svnlook changed -r 15 F://svn//svnrepos");

		BufferedReader reader = new BufferedReader(new InputStreamReader(
				process.getInputStream()));

		String line = null;
		while ((line = reader.readLine()) != null) {
			Matcher m = p.matcher(line);

			if (m.matches()) {
				System.out.println(m.group(2));
			} else {
				System.out.println("unmatch");
			}
		}
		reader.close();
	}
