我想创建一个可附加的excel表.就像我有四列stream1 stream2 stream3 stream4

第一次我只插入数据第一列(stream1)之后,我想逐个完全填充其他列.

这是我正在使用的代码:

 public void createFile(Jqueue stream1, Jqueue stream2, Jqueue stream3, Jqueue stream4) {
    try {

        String filename = "path";
        boolean alreadyExists = (new File(filename)).exists();

        HSSFRow rowhead = sheet1.createRow((short) 0);
        rowhead.createCell((short) 0).setCellValue("Stream 1");
        rowhead.createCell((short) 1).setCellValue("Stream 2");
        rowhead.createCell((short) 2).setCellValue("Stream 3");
        rowhead.createCell((short) 3).setCellValue("Stream 4");


        int i = 1;
        while (!stream1.isEmpty()) {
            String urlstream1 = "";
            String urlstream2 = "";
            String urlstream3 = "";
            String urlstream4 = "";
            HSSFRow row = sheet1.createRow((short) i);
            try {
                if (stream1.size() > 0) { …

我正在使用Web客户端.并通过Web客户端成功登录.但是当我发送第二个获取数据的请求时.我有一个例外

com.gargoylesoftware.htmlunit.UnexpectedPage@6d8d73`

但是当我通过url thruogh brouser时,我得到了一个数据Json格式.

码:

webClient.getPage("http://ajax/stream/refresh-box?r=new&id=2323222&")
