beanvalidation | Library providing custom validators for bean-validation | Validation library

Given this controller method.

I have a handler like this and a custom annotation @ValidRequest:

I have Spring Boot, Maven project that runs perfectly from IDE, so I just made maven install, then placed .war file into Tomcat /webapps. And here's logs, I don't quite understand what is the problem with deployment

I am using Hibernate Validation 6.x. I have a field in an object that I'm validating which contains a list, List<@NotNull Double> doubles for example. The issue I'm facing is that when the list is very large, the performance degradation is substantial. To investigate the issue I implemented the validation of list elements as a custom validator on the List, @ValidDoubles List doubles, using a stream to iterate over the elements, and achieved a ~65% performance improvement for that validator.

After profiling the application I can see that the majority of time is being spent in ListValueExtractor.extractValues, which can be found here. I am hoping that someone could explain why this method seems to be so expensive and if there are any known workarounds.

An example Object:

Trying to create a ValidatorFactory and programmatically add new constraints to the configuration.

Imagine new constraint-mappings files created after initial bootstrap of validation.

But in the unit test below, ValidatorFactory is never created due to the error below.

Any idea how the new constraint-mappings files should be loaded?

I have a method to validate some data in my controller. In that method I validate the incoming data with two different validators. Each validators make some process with the submitted data and if there is a runtime exception they return false.

I have custom exception handler yet I am finding constraint violation exception difficult to handle.

I´m working on this Vaadin Tutorial series.

I´m trying to use Binding but I get the following error in my Terminal:

I want to use io.micronaut.data.repository.CrudRepository. In IntelliJ, even after I added the dependencies I get a complain: Unresolved reference CrudRepository

As far as I can see I added the io.micronaut.data:micronaut-data-hibernate-jpa as expected for Crudrepository
