</beans>
2.实体工具类：Progress.java
package com.yunfang.banks.listener;
public class Progress {
private long pBytesRead;
private long pContentLength;
private long pItems;
public long getpBytesRead() {
return pBytesRead;
}
public void setpBytesRead(long pBytesRead) {
this.pBytesRead = pBytesRead;
}
public long getpContentLength() {
return pContentLength;
}
public void setpContentLength(long pContentLength) {
this.pContentLength = pContentLength;
}
public long getpItems() {
return pItems;
}
public void setpItems(long pItems) {
this.pItems = pItems;
}
@Override
public String toString() {
return "Progress [pBytesRead=" + pBytesRead + ", pContentLength="
+ pContentLength + ", pItems=" + pItems + "]";
}
}
3、文件上传进度监听类：FileUploadProgressListener.java
package com.yunfang.banks.listener;
import javax.servlet.http.HttpSession;
import org.apache.commons.fileupload.ProgressListener;
import org.springframework.stereotype.Component;
@Component
public class FileUploadProgressListener implements ProgressListener {
private HttpSession session;
public void setSession(HttpSession session){
this.session=session;
Progress status = new Progress();//保存上传状态
session.setAttribute("status", status);
}
public void update(long pBytesRead, long pContentLength, int pItems) {
Progress status = (Progress) session.getAttribute("status");
try {
Thread.sleep(5);
} catch (InterruptedException e) {
e.printStackTrace();
}
status.setpBytesRead(pBytesRead);
status.setpContentLength(pContentLength);
status.setpItems(pItems);
//System.out.println(">>>>>>>>>>>>>>>>>>>>"+status);
}
}
4、自定义扩展org.springframework.web.multipart.commons.CommonsMultipartResolver类，重写public MultipartParsingResult parseRequest(HttpServletRequest request) throws MultipartException方法：CustomMultipartResolver.java
package com.yunfang.banks.listener;
import java.util.List;
import javax.servlet.http.HttpServletRequest;
import org.apache.commons.fileupload.servlet.ServletFileUpload;
import org.apache.commons.fileupload.FileItem;
import org.apache.commons.fileupload.FileUpload;
import org.apache.commons.fileupload.FileUploadBase;
import org.apache.commons.fileupload.FileUploadException;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.multipart.MaxUploadSizeExceededException;
import org.springframework.web.multipart.MultipartException;
import org.springframework.web.multipart.commons.CommonsMultipartResolver;
public class CustomMultipartResolver extends CommonsMultipartResolver {
@Autowired
private FileUploadProgressListener progressListener;
public void setFileUploadProgressListener(
FileUploadProgressListener progressListener) {
this.progressListener = progressListener;
}
@Override
@SuppressWarnings("unchecked")
public MultipartParsingResult parseRequest(HttpServletRequest request)
throws MultipartException {
String encoding = determineEncoding(request);
FileUpload fileUpload = prepareFileUpload(encoding);
progressListener.setSession(request.getSession());
fileUpload.setProgressListener(progressListener);
try {
List<FileItem> fileItems = ((ServletFileUpload) fileUpload).parseRequest(request);
return parseFileItems(fileItems, encoding);
}
catch (FileUploadBase.SizeLimitExceededException ex) {
throw new MaxUploadSizeExceededException(fileUpload.getSizeMax(), ex);
}
catch (FileUploadException ex) {
throw new MultipartException("Could not parse multipart servlet request", ex);
}
}
}
5、uploadController.java
@RequestMapping("UserControllers/progress")
public void uploadFile(HttpServletRequest request,HttpServletResponse response,
@RequestParam("file") CommonsMultipartFile file) throws IOException {
response.setContentType("text/html");
response.setCharacterEncoding("GBK");
PrintWriter out;
boolean flag = false;
if (file.getSize() > 0) {
//文件上传的位置可以自定义
flag = FileUploadUtil.upLoadFile(file, request);
}
out = response.getWriter();
if (flag == true) {
out.print("1");
} else {
out.print("2");
}
}
6、FileUploadUtil.java
import java.io.File;
import javax.servlet.http.HttpServletRequest;
import org.springframework.web.multipart.MultipartFile;
public class FileUploadUtil {
public static Boolean uploadFile(HttpServletRequest request, MultipartFile file) {
System.out.println("开始");
String path = request.getSession().getServletContext().getRealPath("upload");
String fileName = file.getOriginalFilename();
System.out.println(path);
File targetFile = new File(path, fileName);
if (!targetFile.exists()) {
targetFile.mkdirs();
}
// 保存
try {
file.transferTo(targetFile);
return true;
} catch (Exception e) {
e.printStackTrace();
return false;
}
}
}
7、前台页面
<%@ page language="java" import="java.util.*" pageEncoding="Utf-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme() + "://"
+ request.getServerName() + ":" + request.getServerPort()
+ path + "/";
%>
