You can store/upload the files in the container. Use <code>request.getRealPath("/")</code> for accessing the path.

Example:

<pre><code> byte[] bytes = fileInput.getBytes(); 

 //bytes to string conversion
 fileToStr = new String(bytes, "UTF-8");
 System.out.println(fileToStr); 
 String name=fileInput.getOriginalFilename(); 

 String ext=name.substring(name.lastIndexOf("."),name.length()); 
 fileName=""+System.currentTimeMillis()+ext; 


 String rpath=request.getRealPath("/"); //path forstoring the file
 System.out.println(rpath); 
 File file=new File(rpath,"csv"); 
 if(!file.exists()){ 
 file.mkdirs(); 
 } 

 File temp=new File(file,fileName); 
 System.out.println("Path : "+temp); 

 FileOutputStream fos= new FileOutputStream(temp); 
 fos.write(bytes); 
 fos.close(); 
</code></pre>

You can create a controller that will return the image data and use it to display on your jsp.

Example controller:

<pre><code>@RequestMapping(value = "/getImage/{imageId}")
@ResponseBody
public byte[] getImage(@PathVariable long imageId, HttpServletRequest request) {
 String rpath = request.getRealPath("/");
 rpath = rpath + "/" + imageId; // whatever path you used for storing the file
 Path path = Paths.get(rpath);
 byte[] data = Files.readAllBytes(path); 
 return data;
}
</code></pre>

And use the below code for displaying:

<pre><code>&lt;img src="/yourAppName/getImage/560705990000.png" alt="myImage"/&gt;
</code></pre>

HTH!

I am working in an e-commercial application in Spring MVC and Hibernate, where I need to store a number of images. 
I want to save the images on a file system (on the server itself to reduce load on the database). My doubt is where exactly I should save images in my project? 

As I have been through some blogs where it was mentioned that images should not be saved in folder with in <code>war</code> file as it can lead to problems when the next version of the app is released (to backup all images and again place them manually) 
Please let me know where exactly I need to save images and how to get that folder path in our java class.

我在一个使用Spring MVC和Hibernate的电子商务应用程序中工作，我需要在其中存储大量图像。我希望将图像保存在一个文件系统上(保存在服务器上，以减少数据库的负载)。我的疑问是，我应该在我的项目中保存图像的确切位置？正如我在一些博客中提到的那样，图片不应该保存在war文件中的文件夹中，因为这可能会在应用程序的...
