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!!!

latest update: javax dependencies are now moved to jakarta package. I tried javax validations but they are not working, when I replace it with jakarta now the validation working fine.

those who are not getting error msg after submitting unacceptable values

just use this dependency only
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-validation</artifactId>
</dependency>

And, import these packages

jakarta.validation.Valid
jakarta.validation.constraints.Size
jakarta.validation.constraints.NotBlank


for @Valid, @Size and @NotBlank annotations...

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.

Those who getting zero errors check your dependencies properly

validation is not working after writing code

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

thank you so much😭

Bahot confusing hai video plzzz clear explain

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?

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?

This was very well Explained. Ty

If data is not mandatory then we want to use regex then how we can use....if data there then check pattern .. otherwise no error...how can we do?

Plz Make video on Design Pattern It is my request

Thanks a lot sir
