好的,我在这里做错了但我不知道是什么。 所以这是代码:
hello.jspx:

<jsp:directive.page contentType="text/html;charset=UTF-8"/>
<jsp:output omit-xml-declaration="yes"/>
<html>
<head><title>Simple jspx page</title></head>
<body>
Place content here ${message}
<form method="get" action="sendParameters">

</table>
</form>

URL yahoo = new URL(myUrl);

String inputLine;
while ((inputLine = in.readLine()) != null)
System.out.println(inputLine);
in.close();
model.addAttribute("message", "Results ready!");
return "results";
}
}
在我按下提交后出现错误,它是以下内容:
HTTP状态500 - 服务器返回HTTP响应代码:400用于URL: http://api.ean.com/ean - 服务/ RS /酒店/ V3 /列表minorRev = 20安培; CID = 55505&放大器; apiKey = 123456789&放大器; customerUserAgent =的Mozilla / 5.0?

有什么想法吗? 谢谢。
