        }
        String name = "test";//用户名
        String password = "123456";//密码
        ISVNOptions options = SVNWCUtil.createDefaultOptions(true);
 
        //实例化客户端管理类
        ourClientManager = SVNClientManager.newInstance(
                (DefaultSVNOptions) options, name, password);
 
        //要把版本库的内容check out到的目录
        File wcDir = new File(localurl);
 
        long workingVersion = -1;
        try {

        } catch (Exception e) {
            e.printStackTrace();
        }
        model.addAttribute("msg", "把版本：" + workingVersion + " check out 到目录：" + wcDir + "中。");
