Hey guys if you're facing some validation issues, just use spring boot starter validation dependency ONLY instead of using validation API and hibernate validator dependencies. then update your maven project and rerun the application. It worked for me!!!
Thank you
Thanks
Thanks
For me that spring bean and hibernate validator dependencies were working fine, but this dependency is better and easy to understand, thank you
@@YashSingh-xs5yj It's not working for me
I have been following your videos on spring. They are really good. All thanks to you.

After a decades I felt like I will learn the I can learn it as your wonderful Spring videos helped to learn lots of concept, which is much apricated because nobody is able to share similar content but since it's almost 3 years old in this time duration Thymleaf people made changes which get me stuck again it's being a week I am stuck on this video trying to find the solution but feels like I have no where to go :(

I am also facing the same problem.
Well explaination
Superb video . Ek cheez confirm karni thi , isme ham alag alag code likh rhe hain email aur username validation ka html me using thymeleaf. Isko generic karne ke liye ham fragment bana sakte hain jisme input me parameter daal denge email ya username aur wo FRAGMENT yaha include kar lein . Code generic ho jaayega poore project ke liye hamara . Ab jisko b call karna hai wo us fragment ko include karle
I'm unable to validated the input data I also added hibernate related dependency also added @Valid annotation, clean and rebuild the project for 2nd try also tried to ad the jar files in project structures but still not able to run validation. After @Valid still my programme is taking null data in db
did you find any further solution on this?
If u using newer version of Java EE more than Java EE 7 then import jakarta validation it will work
i am using jdk 11 and spring boot 2.6.4 @Size(max = 5, message = "A persons name must not be longer than 5 characters.") annotation is not working .Is there any problem.

Thank you Sir, I've been following your tutorial and very awesome and helpful; but I've got a question about how to validate ManyToOne r/s, for example Trainee and course, one trainee can take many course and if the registered trainee has already taken the course, the system rejects it while registration using course_id and trainee_id (because they are trying to take the same course twice),..the message displayed is:"this trainee has already taken this course". Could you kindly help on this problem using Springboot Validator?
thank you so much😭
liked the content
Thanks Sir
those who are not getting error msg after submitting unacceptable values
just use this dependency only
org.springframework.boot
spring-boot-starter-validation
And, import these packages
jakarta.validation.Valid
jakarta.validation.constraints.Size
jakarta.validation.constraints.NotBlank
for @Valid, @Size and @NotBlank annotations...
Thank you :) It is working now..
no need to add this ?
org.hibernate
hibernate-validator
6.1.5.Final
Sir can you explain the purpose of sending empty object to the form? Cause even if we do not send it it is working. I am new, so I am having doubt.
Another one in MVC we was using Model to send data to a page along with @moduleattribute..but here we are not..and it is working how and why?
As much as I understood model attribute we used to send the view data to controller altogether instead of using RequestParm annotation and taking view values one by one and if you dont send empty object then we have used th:object =loginData that means we have sent the object which is being used here and will be used if we dont send we will get error

Thank you so much Sir for these videos. But I am not able to get errors in result. @Valid is not working or what could be the reason. Downloaded your code also but same issue.
if you have found the solution then please let me know the solution. It would be very helpful.
How can you download the code ?
Those who getting zero errors check your dependencies properly
Validation is not able to catch the errors. I have checked the dependencies properly but nothing is working.
Any help would be appreciated.

Hi Durgesh,
When i am adding server side validation then i am not getting error on login page it redirecting me to
Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.
