As Usual you always come with amazing content, thank you 😊, waiting for the second part
Hi bro , Content is very good and new. I want to say something today's many companies are storing or signing their file or photo to AWS S3, One Drive or any cloud provider and returning the URL and that URL is storing inside of these DB and these looks good and easy even If we store blob data in db it will be very huge and it will also impact the DB Performance while hitting multiple request. It's my suggestion only.
Yes i agree with you but Already AWS S3 i covered buddy.
Thank you sir for this vedio I have implemented this project.. learned new concept
Storing file/img in cloud and keeping the reference in DB is better approach.
As always good video❤
Do you have any link for that tutorial. Please share.
Thanks, I needed this for a PoC for my client, it will help me greatly.
highly educational videos in a easy and simple way thankQ
I'm 4 minutes in and love it. Hopefully that stay the same throughout the video.
Lovely content!! This is a great service. God bless you.
Bro thanks for your wonderful tutorial videos with practical straight to the point approach. I really appreciate it.
Before compression byte array length = 149687, after compression = 149337. Boi that's some serious compression. I couldn't store the image because the length in the @Column for imageData was set to 1000 so I set it to 500 000 recreated the table all good.
A good third part of this series would be to show AWS S3 - managed service that is used across many projects/companies

Hi,
ImageData.builder() method is not present, even if @Builder annotation is added in the entity class. What is the issue ?
Did you configure Lombok in your ide?
Thank you Java Techie this super useful. Can you give us something about Spring boot configurations. I would also love to learn how to send email and notification in spring boot.
Thanks for this video
thank you , very much!
Very Helpful Brother 👏
Please make a video on upload any type of file using file system approach.

Hi sir thankyou sir it is very nice clear explanation.sir I want you make a video notification in spring boot
Notification means email or sms what kind of notification you are expecting
@@Javatechie sir sms type notification like Flipkart notification because we currently working project on affiliate marketing
Hi Nice content,
I’m implementing below problem on tha I stuck can you give guide me here.
There are multiple processes like A B C D etc
Now there is some sequence of execution of these process like
A -> D-> F
For example 1st Process A starts then once A complete then D will start if A fail then K will start once K complete the Again D and then F will start . Every time based on previous process status we will execute next process.
All are spring batch process can be start executing by invoking their Rest end point
It can be implemented in java
Thanks in advance
Please make file system tutorial for better understanding
Yes its already uploaded please check
Hi sir
I have requested for content regarding how to add key to the header when making call from our soap client.I have seen many others also requested on same.Please make a video on it
Are you talking about soap web services?
@@Javatechie yes am not finding any good resource for that...your video was great but didn't include adding header
Thanks a lot
Thanks a lot. was great for me Short and useful
Would you please do the second part?
Okay I will
Nice video 👌 does it supports all file types such as pdf, doc, XLS?
No you need to change the file type in the controller
Rahmat janob
This is a very useful way to save data as an image, but does it work with pdf file or any other Microsoft file?
Yes it will work .
@@Javatechie thanks for your wonderful tutorial videos
and yeah after i practiced this with Microsoft file combine with Mailmerge code it working much faster
Could you please make video on this
HOW TO READ THE EXCEL AND STORE IN DATABASE using Spring boot
Thank you ❤❤❤
🤩
Thats cool video but i want to store the image in file system.Please make that video as production level code.
Okay I will
@@Javatechie Thanks
For now it works for me but, should it appear in the database? I'm running 'select * from imageData;' and getting no results, after uploading an image. Thank you in advance!
It should be store in db please debug and validate once
@@Javatechie testing with postman, it's working both for uploading and downloading
So, with mysql workbench, it doesn't work with the query I have shared. But I have checked with DBeaver, and they appear over there. So, it is working
Thank you for the great video! What will happen if the file we are trying to upload is a virus or another malicious file? Is it possible to scan the file before we save it in our database? How can we do that?
The scanning part i am not sure I need to check .
Need to allow Content-Disposition header in Controller or WebMvcConfig so that frontend can call the API with actual filename
You can configure that while enabling cross origin
Hi, would you mind making some videos on Dropwizard too ?
I'm a Spring developer, but in my new project they are using Dropwizard with Rabbitmq for creating the microservices archiitecture and even the basic thigs like Dependency Injection is a pain since Dropwizard doesn't provide any IOC container like spring does.
yes bro , my requirement is also same ..could you pls mke a video on this?
i used the same way you did in your video but for an PDF file not for an image, uploading worked but when i try to download the file i can't decompress the file as an PDF file and i didn't find how to do it.
So if you can help me with the method of decompressing a PDF file from the database I will be thankful to you
Hi bro same problem did you find a solution
Check the response type and do the code change accordingly
public byte[] downloadImage(String fileName) {
Optional dbImageData=storageRepository.findByName(fileName);
byte[] images=ImageUtils.decompressImage(dbImageData.get().getImageData());
return images;
}
in this section , getImageData() is error in my program. How can I resolve this?
What did you use in your sql for the image BYTE or BYTEA?
Will we be able to upload multiple documents/pictures simultaneously through this??
Yes but you need to change controller logic to accept bulk file
Hi, what data type did you use to create your column for imagedata in the database? Did you use varchar()?
It's byte[]
Problem is I can't create the table in MySQL Workbench with "byte" as data type for the imagedata column..
`imagedata` BYTE(1000) DEFAULT NULL,
is this how it works?
Why are you creating manually. Use the help of jpa
@@Javatechie It's because I'm using DDL scripts to create tables in my DB.
hay que cerrar el estadio, solo los genios hacen eso
I'm facing that unsupported mediaType exception
Check your request buddy.
Should the service layer be a class or an interface?
It should be interface then next you have to add it's implementation
hi i understood what u did but how to do ONE TO ONE operation if another entity consist of product details ,price descipton and we want to upload the image at same time so can u please tell me how to do it?
Where can I find articles on the topic "Spring Boot File Upload using SOAP api"?
Bro I have face one problem Builder method does not come.what is t the problem?
You need to configure Lombok in your idea 💡
How to delete the image/file uploaded automatically from our local system, after it is persisted in the database. Because I am seeing that it is getting saved in my local folder structure
contentType(MediaType.valueOf("image/png")) instead of this how we can set dynamically if it pdf then i want pdf response if it is excel then i want excel format as response like that based on type I want to get dynamically
Any reason you clubbed the controller class stuff into main class?
No reason it's just to save the time
6:54
Can anyone give a little discription about optional..
Sir same code but getting "the field image exceeds it's maximum permitted size of 1048576 bytes
when i try to get, Large Objects may not be used in auto-commit mode. occurs
hi
What type of data do you put in the imageData column in mysql?
HI Sir , Can you please make a video on Junit testing of application with Rancher Desktop with Gcloud Spanner emulator. Setup and also one demo Project on this.
- Requirement is to perform Junit test with real data without hitting Gcloud database every time when we perform test so for that we can use spanner emulator to test with real data Locally and Rancher desktop ( Alternative of Docker Desktop )to run Kubernetes locally.
So Sir can you please help me out to configure and do one POC on this requirement.
Thank you
why do we have to compress and decompress ?
Can you please create videos on app dynamics, data dog and terraform ?
how can we store images on AWS, then getting on proper ms like Book?
Hello Sir How can we store image size more than 1mb ? I had added multipart-config additional configuration to increase size still didnt work , how can we achieve that ?
Please make part 2
Sure i will
Sir getting error that is data too long for column image _data at row1
Please check my code which I shared and figure out the changes
@@Javatechie same content I had done but getting error how solve this one sir
Hey bro could u pls create one api for get download all files from server at a time
This is simple right just give the path of server then File.files() will give array of file from that path just loop them and call download method in loop
In this code large objects may not be auto commit mode how slove this error
Can we use same code for other file format like upload/download XML file
Yes we can just change the media type
Like i upload any file it will work?
Yes
so would a collections of images be retreived
Not getting you
@@Javatechie as in how would i retrieve a collection of images from the database,i tried modyfiying the code to return a list of byte (List) but it didnt work
@@Javatechie never mind i figured it out
This does not work in Postgres , How can this be done in Postgres ?
Check what binary format it supports
@@Javatechie Postgres has BYTEA format, so had to add this explicitly in entity. Then it resolved the issue
@Column(columnDefinition = "BYTEA")
private byte[] data;
Does it work or still having issues
@@Javatechie the upload part works but when getting the image from DB it is giving PSQLException : Bad value for type long
I need to check buddy i haven't tried with postgres
