Question

我想将文件上传到项目中的文件夹。但是当我选择一个文件并单击上传按钮时，我收到以下错误： HTTP状态500 - 请求处理失败;嵌套异常是java.lang.IllegalArgumentException：预期的MultipartHttpServletRequest：是否配置了MultipartResolver？

这是我的MultipartResolver bean：

<beans:bean id="multipartResolver" 
    class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
    <beans:property name="maxUploadSize" value="10000000"/>
</beans:bean>

这是我的控制器：

@Controller
public class UploadController {
private String folderTujuanUpload="/uploads";
private static final Logger LOGGER = LoggerFactory.getLogger(UploadController.class);

@RequestMapping(value = "/upload/form",method = RequestMethod.GET)
public void tampilkanFormUpload(){}


 @RequestMapping(value = "/upload/form",method = RequestMethod.POST)
 public String prosesFormUpload(HttpSession session, @RequestParam("filegambar") MultipartFile                   hasilUpload) throws IOException{

String lokasiUpload = tujuanUpload(session).getAbsolutePath();     

 LOGGER.debug("name File [{}]",hasilUpload.getName());
 LOGGER.debug("Size File [{}]",hasilUpload.getSize()); 
 LOGGER.debug("Type File [{}]",hasilUpload.getContentType());

 File tujuan = new File(lokasiUpload + File.separator + hasilUpload.getOriginalFilename());
 try{
     hasilUpload.transferTo(tujuan);   
 }catch (Exception ex) {
     LOGGER.error("cant upload file");
     LOGGER.error("Penyebab : {}", ex.getMessage());
 }
     return "redirect:list";
 }





 @RequestMapping(value = "/upload/list")
 public ModelMap tampilkanhasilUpload(){
     ModelMap mm=new ModelMap();
     return mm;
 }
 private File tujuanUpload(HttpSession session){
     String lokasiFullPath = session.getServletContext().getRealPath(folderTujuanUpload);
     LOGGER.debug("lokasi full path : [{}]",lokasiFullPath);

     File hasil = new File(lokasiFullPath);
     if (!hasil.exists())
     {
         LOGGER.debug("lokasiblabla");
     hasil.mkdirs();
     }
     return hasil;
 }

}

这是我拥有的jsp页面：

form.jsp

<%@page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
    <title>JSP Page</title>
</head>
<body>
    <h1>form upload</h1>

    <form method="POST" enctype="multipart/form-data">

        <table border="0">
            <tbody>
                <tr>
                    <td>pilla palla </td>
                    <td>
                        <input type="file" name="filegambar">
                    </td>
                </tr>
                <tr>                        
                    <td>&nbsp;</td>
                    <td>
                        <input type="submit" value="Üpload">
                    </td>
                </tr>     
            </tbody>                
        </table>

    </form>

</body>
</html>

的List.jsp：

<%@page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
    <title>upload</title>
</head>
<body>
    <h1>hassandsjaiadsf upload</h1>
</body>
</html>

未配置Spring MultipartResolver
