请问这样的写法是哪里错了，不能导入，也不报错！
<form action="http://localhost:8080/context/servler3" method="post" enctype="multipart/form-data">
<input type="text" name="name"/>
</br>
<input type="file" name="file"/>
</br>
<input type="submit" value="导入word"/>
</form>
package sc;
import org.apache.commons.fileupload.FileItem;
import org.apache.commons.fileupload.FileUploadException;
import org.apache.commons.fileupload.disk.DiskFileItemFactory;
import org.apache.commons.fileupload.servlet.ServletFileUpload;
import org.apache.poi.hwpf.HWPFDocument;

@WebServlet(name = "Servlet3")
public class Servlet3 extends HttpServlet {
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
try {
DiskFileItemFactory disk = new DiskFileItemFactory();
ServletFileUpload servletFileUpload = new ServletFileUpload(disk);
//这个载入会有流异常
List<FileItem> fileItemList = servletFileUpload.parseRequest(request);
for (FileItem item : fileItemList)
if (item.isFormField()) {
String name = item.getFieldName();
String value = item.getString("UTF-8");
System.out.println("name:" + name);
System.out.println("value:" + value);
} else {
HWPFDocument doc = new HWPFDocument(item.getInputStream());
System.out.println(doc.getDocumentText());
doc.close();
}
} catch (FileUploadException e) {
e.printStackTrace();
}

同学是说跳转有问题吗？还是指的什么问题？
同学的Servlet确实可以出现结果，只是jsp页面中的跳转路径没有和Servlet对应起来，这是我帮助你修改以后的代码：
<%@ page contentType="text/html;charset=UTF-8" language="java" %> <html> <head> <title></title> </head> <body> <form action="http://localhost:8080/Servlet3" method="post" enctype="multipart/form-data"> <input type="text" name="name"/> </br> <input type="file" name="file"/> </br> <input type="submit" value="导入word"/> </form> </body> </html>
Servlet：
package sc;
import org.apache.commons.fileupload.FileItem;
import org.apache.commons.fileupload.FileUploadException;
import org.apache.commons.fileupload.disk.DiskFileItemFactory;
import org.apache.commons.fileupload.servlet.ServletFileUpload;
import org.apache.poi.hwpf.HWPFDocument;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.*;
import java.util.List;
@WebServlet("/Servlet3")
public class Servlet3 extends HttpServlet {
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
try {
DiskFileItemFactory disk = new DiskFileItemFactory();
ServletFileUpload servletFileUpload = new ServletFileUpload(disk);
//这个载入会有流异常
List<FileItem> fileItemList = servletFileUpload.parseRequest(request);
for (FileItem item : fileItemList)
if (item.isFormField()) {
String name = item.getFieldName();
String value = item.getString("UTF-8");
System.out.println("name:" + name);
System.out.println("value:" + value);
} else {
HWPFDocument doc = new HWPFDocument(item.getInputStream());
System.out.println(doc.getDocumentText());
doc.close();
}
} catch (FileUploadException e) {
e.printStackTrace();
}
}
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
doPost(request, response);
}
