一、單檔案上傳
1.jar包
2.springmvc-servlet.xml配置
添加以下代碼
<!-- 檔案上傳設定 -->
<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<property name="defaultEncoding" value="utf-8"></property>
<property name="maxUploadSize" value="10485760000"></property>
<property name="maxInMemorySize" value="4069"></property>
</bean>
3.jsp頁面編寫
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>單檔案上傳</title>
</head>
<body>
<div style="margin: 0 auto; margin-top: 100px;">
<form action="oneUpload.html" method="post" enctype="multipart/form-data">
<p>
<span>檔案</span>
<input type="file" name="imageFile">
</p>
<p>
<input type="submit" value="送出">
</p>
</form>
</div>
</body>
</html>
4.controller檔案編寫
package com.Intimate.Controller;
import java.io.File;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;
import java.util.Map;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.multipart.MultipartFile;
import org.springframework.web.multipart.MultipartHttpServletRequest;
import org.springframework.web.servlet.ModelAndView;
import com.upload.Common.ToolUtil;
@Controller
public class UploadController {
@RequestMapping("/oneUpload")
public String oneUpload(@RequestParam("imageFile") MultipartFile imageFile, HttpServletRequest request){
String uploadUrl = "F:\\image\\";
String originalFilaname = imageFile.getOriginalFilename(); //拿到圖檔的原始名稱
String newFilename = ToolUtil.makeFileNameByTime(originalFilaname);
//判斷檔案路徑是否存在，如果不存在則建立檔案路徑
File dir = new File(uploadUrl);
if(!dir.exists()){
dir.mkdirs();
}
System.out.println("檔案上傳到：" + uploadUrl + newFilename);
//判斷上傳檔案是否存在，如果不存在則建立檔案
File targetFile = new File(uploadUrl + newFilename);
if(!targetFile.exists()){
try {
targetFile.createNewFile();
} catch (IOException e) {
e.printStackTrace();
}
}
//把上傳的檔案移動到targetFile中,即将記憶體中的資料寫入磁盤中
try {
imageFile.transferTo(targetFile);
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
request.setAttribute("imageName", newFilename);
// return "redirect:http://localhost:8080/springmvc_upload/upload/" + filaname;
return "uploadResult";
}
}
5.工具類編寫
package com.upload.Common;
import java.text.SimpleDateFormat;
public class ToolUtil {
public static String makeFileNameByTime(String filename){
String fileExtName = filename.substring(filename.lastIndexOf(".")+);
//為防止檔案覆寫的現象發生，要為上傳檔案産生一個唯一的檔案名
SimpleDateFormat sdf2 = new SimpleDateFormat("yyyy_MM_dd_HHmmss");
String time = sdf2.format(new java.util.Date());
return time + "."+fileExtName;
}
public static String makeFileNameRand(String filename){
String fileExtName = filename.substring(filename.lastIndexOf(".")+);
return UUID.randomUUID() + "."+fileExtName;
}
}
7.結果展示頁面編寫
<title>多檔案上傳結果</title>
</head>
<body>
<div style="margin: 0 auto; margin-top: 100px;">
<img alt="" src="/pic/${imageName}">
</div>
</body>
</html>
/pic 是tomact的虛拟路徑，對應着磁盤的一個實體途徑，也就是上面圖檔上傳的路徑
設定步驟：
1.打開server面闆
2.輕按兩下server，打開設定界面
3.點選Add External Web Module按鈕，選擇路徑
Document base 就是存放圖檔的實體路徑；
Path 是虛拟路徑的名稱，記得 / 不能忘記；
點選ok,就完成了。
如果上面的方法沒反應，還有一種直接改配置檔案的方法：
打開tomact檔案夾下的conf檔案下的Server.xml檔案
在
<Host></Host>
中最後加一句
儲存即可
如果改配置檔案也沒用，那可能是用eclipse，有一個Server檔案夾
那麼就需要改Server中的server.xml
二、多檔案上傳
jar包和springmvc-servlet.xml的設定和單檔案上傳一緻，隻需要修改jsp頁面和controller檔案即可
1.jsp頁面編寫
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>多檔案上傳</title>
</head>
<body>
<div style="margin: 0 auto; margin-top: 100px;">
<form action="moreUpload.html" method="post" enctype="multipart/form-data">
<p>
<span>檔案1:</span>
<input type="file" name="imageFile1">
</p>
<p>
<span>檔案2:</span>
<input type="file" name="imageFile2">
</p>
<p>
<input type="submit" value="送出">
</p>
</form>
</div>
</body>
</html>

Map<String, MultipartFile> files = multipartHttpServletRequest.getFileMap();
// String uploadUrl = request.getSession().getServletContext().getRealPath("/") +"upload/";
String uploadUrl = "F:\\image\\";
//判斷檔案路徑是否存在，如果不存在則建立檔案路徑
File dir = new File(uploadUrl);
if(!dir.exists()){

}
List<String> fileList = new ArrayList<String>();
for(MultipartFile file : files.values()){
String originalFilaname = file.getOriginalFilename(); //拿到圖檔的原始名稱
String newFilename = ToolUtil.makeFileNameRand(originalFilaname);
File targetFile = new File(uploadUrl + newFilename);
if(!targetFile.exists()){
try {
targetFile.createNewFile();
} catch (IOException e) {

}
//把上傳的檔案移動到targetFile中
try {

fileList.add(newFilename);
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
}
request.setAttribute("files", fileList);
return "uploadResult";
}
}
