java - osql -S 没有给我预期的结果

Question

我正在尝试用 Java 编写一个程序，该程序使用 osql 在服务器上生成数据库列表。我的代码如下:

    public Object[] findDataBases(String server, String user, String passwd){
    str = new String[] {"cmd.exe", "/c", "osql", " -S ", 
            server, " -U", user, "&&", "-P ", passwd, 
                            "&&", "sp_databases","&&", "GO"     
            };
    Runtime rt = Runtime.getRuntime();
    try{

        Process p = rt.exec(str);
        InputStream is = p.getInputStream();
        InputStream err = p.getErrorStream();
        InputStreamReader in = new InputStreamReader(is);
        InputStreamReader er = new InputStreamReader(err);

        BufferedReader buff = new BufferedReader(in);
        String line = buff.readLine();
        ArrayList<String> listDatabases = new ArrayList<String>();
        while (line != null){
            listDatabases.add(line.trim());
            /*for (int i = 0; i<4; i++){
                buff.readLine();
            }*/
            line =buff.readLine();
        }
        System.out.println("error stream:");
        buff = new BufferedReader(er);

        while ((line=buff.readLine()) != null){
            System.err.println(line);
        }

        databases = listDatabases.toArray();
        return databases;
    }

当我运行此命令时，由于某种原因，我收到一条消息，就像我运行了 osql -? 一样，但我显然没有这样做。

我不确定我做错了什么，所以任何帮助将不胜感激。非常感谢!

从参数中删除空格，去掉 && :str = new String[] {"cmd.exe", "/c", "osql", "-S", 服务器, "-U", 用户, "-P", passwd, "-Q", "sp_databases"};
