我正在尝试将.csv文件从JSP上传到Servlet。它在我的本地计算机(Websphere 8.5.5.11上的Java 1.8)上可以完美运行,但是当我将其移至测试环境(WebSphere 8.5.5.12上的Java 1.6)时,出现错误消息:
java.lang.UnsupportedOperationException:SRVE8020E:Servlet不接受多部分请求
这看起来很奇怪,因为isMultipart返回为true。
这是我的JSP表单:
<form method="POST" name="batchForm" action="BatchTierProcessing" enctype="multipart/form-data">
<input type="hidden" name="pageName" value="batchTierProcess"/>
<text>Upload File for Batch Processing:</text>
<input type="file" name="file" id="file"/>
<input type="submit" value="Upload" name="upload" id="upload"/>
</form>
这是我的servlet:
@WebServlet(name = "UWTSAS", urlPatterns = {"/UWTSAS"}, loadOnStartup = 1)
@MultipartConfig
public class PMSTandalone extends AWRServlet {
@Override
protected void doPost(HttpServletRequest aRequest, HttpServletResponse aResponse) throws ServletException, IOException {
boolean isMultipart = ServletFileUpload.isMultipartContent(aRequest);
FileItem csv = null;
String pageNameMultiPart = "";
Exception fakeException = new Exception();
PageNameEnum pageName = null;
Part filePart = null;
//if a multipart request (batch process) grab file before request is touched by anything else
if(isMultipart) {
LogMessageUtility.log("INFO", "Is multipart request", fakeException);
filePart = aRequest.getPart("file");
pageName = PageNameEnum.getValue("pmSABTS");
LogMessageUtility.log("INFO", "Page Name Multipart", fakeException);
}
else {
pageName = PageNameEnum.getValue(aRequest.getParameter("pageName"));
}
HttpSession aSession = aRequest.getSession(false);
if(aSession == null) {
aSession = aRequest.getSession(true);
}
buildUserSession(aRequest, aSession);
boolean batchSuccessful = true;
String destination = "PMStandBatchRes";
LogMessageUtility.log("INFO", "Batch Processing Started", fakeException);
try {
batchSuccessful = getFinalScoresBatch(aRequest, aResponse, aSession, filePart);
}
catch(Exception e) {
LogMessageUtility.log("ERROR", e.getMessage(), e);
}
}
if(!destination.equals("") && batchSuccessful) {
dispatchToResource(aRequest, aResponse, WebRatingProperty.getSetting(destination));
}
}
我尝试将Eclipse设置为使用Java 6编译该项目,但没有运气。据我所知,我无法将本地WebSphere实例设置为使用1.6运行。我尝试使用Apache Commons FileUpload和Commons IO,而不是通过Java本身没有运气,并且开始考虑找出如何手动解析请求的方法。
任何人都知道发生了什么事,或者对我应该尝试的事情有任何想法?我已经浏览了以下问题和答案:
How to upload files to server using JSP/Servlet?
Convenient way to parse incoming multipart/form-data parameters in a Servlet
How can I read other parameters in a multipart form with Apache Commons

在此先感谢您的帮助或想法。

我知道了。必须删除@MultipartConfig批注,并实现javax.servlet.Servlet接口,并使用Apache Commons FileUpload库。
