从Windows 2012标准版升级到数据中心版

今天用java做了个简单的类似IE一样能够下载CVS格式的文件，刚开始由于前端代码是用ajax提交到后台，因此无论怎么做都无法实现，用firefox查看一切正常，但是返回的response总是空，进过调查发现好像不能用ajax提交，具体原因不是很明白，最后改成form提交一切正常，代码如下（play framework）：

 

1，前段代码：

<form action="/schedule/download" method="post">

<input type="submit" class="k-button download-button" style="width:50px" value=" " />

<form>

 

2，后台代码：

 

public static void download () {

try {

// 数据库中查询出来的数据

List list = Schedule.findAll();

//Generate binary data;

        ByteArrayOutputStream outputStream = new ByteArrayOutputStream();

        boolean first = true;

        for (int i = 0; i < list.size(); i++) {

        StringBuilder builder = new StringBuilder();

        if (first) {

// 放入标题

        String title = "Driver Number" + "," + "Vehicle Number" + "," + "Start Time" +     "," + "End Time" + "," + "Line" + "," + "Duty ID";

        builder.append(title);

        builder.append("\r\n");

        first = false;

        }

        Schedule sch = (Schedule)list.get(i);

        String str = sch.driver.number + "," + sch.vehicle.number + "," + sch.startTime + "," + sch.endTime + "," + sch.serviceNumber + "," + sch.dutyId;

        builder.append(str);

        builder.append("\r\n");

    String line = builder.toString();

    outputStream.write(line.getBytes("UTF-8"));

    outputStream.flush();

       }

       outputStream.close();

       byte[] data = outputStream.toByteArray();

 

       //Create input stream

       ByteArrayInputStream inputStream = new ByteArrayInputStream(data);

 

       //Render attachment

       renderBinary(inputStream, "schedule.csv", data.length, "text/csv", true);

} catch (IOException e) {

}

}
