TOMCATサーバーでファイルのアップロードを保存する場所を設定するにはどうすればよいですか?
私は使用commons.fileupload
していますが、現状では複数の.tmp
ファイルを保存できますcatalina_base/temp
が、アップロードしたフォルダを元の形式で保存することを目的としています。d:\\dev\\uploadservlet\\web\\uploads
この質問が曖昧であることは知っていますが、正直なところ、私はサーブレットを短期間使用しており、全体像をまだ理解していません。コードの提案やチュートリアルへのリンクをいただければ幸いです。
アップロードを処理するサーブレットコードは次のとおりです。
package test;
import java.io.IOException;
import java.io.PrintWriter;
import java.util.Iterator;
import java.util.List;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;
import com.oreilly.servlet.MultipartRequest;
import org.apache.commons.fileupload.FileItem;
import org.apache.commons.fileupload.FileItemFactory;
import org.apache.commons.fileupload.FileUploadException;
import org.apache.commons.fileupload.disk.DiskFileItemFactory;
import org.apache.commons.fileupload.servlet.ServletFileUpload;
public class TestServlet extends HttpServlet {
private static final long serialVersionUID = 1L;
public static final long MAX_UPLOAD_IN_MEGS = 5;
public void doGet(HttpServletRequest request, HttpServletResponse response) throws IOException {
doPost(request, response);
}
public void doPost(HttpServletRequest request, HttpServletResponse response) throws IOException {
response.setContentType("text/html");
PrintWriter out = response.getWriter();
//This is the folder I want to use!!
//String uploadFolder = "d:\\dev\\uploadservlet\\web\\uploads";
boolean isMultipartContent = ServletFileUpload.isMultipartContent(request);
if (!isMultipartContent) {
out.println("Upload unsuccessful<br/>");
return;
}
out.println("The following was uploaded:<br/>");
FileItemFactory factory = new DiskFileItemFactory();
ServletFileUpload upload = new ServletFileUpload(factory);
upload.setSizeMax(MAX_UPLOAD_IN_MEGS * 1024 * 1024);
TestProgressListener testProgressListener = new TestProgressListener();
upload.setProgressListener(testProgressListener);
HttpSession session = request.getSession();
session.setAttribute("testProgressListener", testProgressListener);
try {
List<FileItem> fields = upload.parseRequest(request);
out.println("Number of fields: " + fields.size() + "<br/><br/>");
Iterator<FileItem> it = fields.iterator();
if (!it.hasNext()) {
out.println("No fields found");
return;
}
out.println("<table border=\"1\">");
while (it.hasNext()) {
out.println("<tr>");
FileItem fileItem = it.next();
boolean isFormField = fileItem.isFormField();
if (isFormField) {
out.println("<td>regular form field</td><td>FIELD NAME: " + fileItem.getFieldName() +
"<br/>STRING: " + fileItem.getString()
);
out.println("</td>");
} else {
out.println("<td>file form field</td><td>FIELDNAME: " + fileItem.getFieldName() +// <br/>STRING: " + fileItem.getString() +
"<br/>NAME: " + fileItem.getName() +
"<br/>CONTENT TYPE: " + fileItem.getContentType() +
"<br/>SIZE (BYTES): " + fileItem.getSize() +
"<br/>TO STRING: " + fileItem.toString()
);
out.println("</td>");
}
out.println("</tr>");
}
out.println("</table>");
} catch (FileUploadException e) {
out.println("Error: " + e.getMessage());
e.printStackTrace();
}
}
}
...そしてそれはこのHTMLフォームからの情報です:
