我正在尝试用Java编写一个程序,使用osql生成服务器上的数据库列表。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;
    }

当我运行它时,出于某种原因,我得到一条消息,好像我已经运行osql -?,我显然没有这样做。

我不确定我做错了什么,所以任何帮助都会受到赞赏。非常感谢!

从参数中删除空格&amp;&amp;关: str = new String [] {“cmd.exe”,“/ c”,“osql”,“ - S”,server,“ - U”,user,“ - P”,passwd,“ - Q”,“sp_databases “};
