Question

我正在开发一个Spring-MVC项目，该项目需要应用程序的用户上传图像。我正在使用apache.commons，Eclipse Mars2和Java1.8。每次我测试上传时，eclipse控制台都会抛出这个：

编辑：似乎问题是找到独立于操作系统的项目路径。目前我们正在使用：

File localFile = new File(System.getProperty("user.home")+File. separator+ "workspace"+File. separator+"ProyectoSpring"+File. separator + "WebContent" + File. separator+"usr"+File. separator+imagen.getNombreImagen());

问题是工作区是硬编码的，应用程序正由更多人开发。有没有办法找到项目的路径？ user.dir返回eclipe路径，而不是项目或工作区。

原始问题：

控制器方法：

@RequestMapping(value="/uploadImagen" , method=RequestMethod.GET) 
public String addImagen(Model model) {
    model.addAttribute("imagen", new Imagen());
    return "imagen/uploadImagen";
}

@RequestMapping(value="/uploadImagen", method=RequestMethod.POST) 
public String processAddSubmit(@ModelAttribute("imagen") Imagen imagen,
                                BindingResult bindingResult) { 
    //if (bindingResult.hasErrors())
    //      return "imagen/uploadImagen";
    //

    try {

        String aux = imagen.getFichero().getOriginalFilename();
        imagen.setImageName(System.getProperty("catalina.home")+ File. separator +"ProyectoSpring"+ File. separator +"WebContent"+ File. separator +"usr"+ File. separator + aux);
        grabarFicheroALocal(imagen);
    } catch (Exception e) {
        e.printStackTrace();
        return "user/error";
    }        
     return "redirect:../index.jsp";
 }


private void grabarFicheroALocal(Imagen imagen) throws Exception {

    CommonsMultipartFile uploaded = imagen.getFichero();
    File localFile = new File(imagen.getImageName());
    FileOutputStream os = null;

    try {
        os = new FileOutputStream(localFile);
        os.write(uploaded.getBytes());

    } finally {
        if (os != null) {
            try {
                os.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }
}

来自对象的摘录：

import org.springframework.web.multipart.commons.CommonsMultipartFile;



public class Imagen {

    private String imageName;
    private CommonsMultipartFile fichero;


public Imagen(){
    super();
}   

//GETTERS AND SETTERS

public CommonsMultipartFile getFichero() {
    return fichero;
}

public void setFichero(CommonsMultipartFile fichero) {
    this.fichero = fichero;
}
...

当然，图片未上传。在使用Linux的其他PC（我使用的是W7-64）中，代码可以工作，所以我怀疑它可能是权限问题，但路径中的所有文件夹都具有写权限。有任何想法吗？ THX。

java.io.FileNotFoundException使用apache.commons
