The RESTeasy validation doesn't work with packaging war

[avaysberg]

Hi,

i found out some problem with this module. The RESTeasy validation doesn't work. This happens in case if we use resteasy-spring-boot in web-application (packaging war):

What we make?

1. we use the sample-app
2. we change to use the war ->(war)
3. deploy on tomcat
4. added to the @notempty > public EchoMessage echo(@notempty String echoText) {
5. send request with empty body and we receive the 200, but should be a 400.

If we do the same with jar it work and we receive 400.

Can you us help and say, how we can solve this problem?

[fabiocarvalho777]

Could you please share in GitHub a modified version of sample-app with bean validations that work as JAR and a modified version of sample-app with bean validations that does NOT work as WAR?
Thanks.

Hi,

Hi,
i think, that the problem is, that standalone spring boot find this dependencies:

org.jboss.resteasy
resteasy-validator-provider-11
3.1.3.Final

but the web spring boot doesn't find it. The question is why? RESTEasy (https://docs.jboss.org/resteasy/docs/3.1.3.Final/userguide/html/Validation.html)

[msauza]

"Web spring boot" means that runs on tomcat (or other servlet container)?
I made some changes on your project; execute using:
sample-app-gradle.zip

$ gradle clean build
$ java -jar .\build\libs\sample-app.war

POST /sample-app/echo HTTP/1.1
HOST: localhost:8080
content-length: 0
content-type: text/plain

Response 404

[fabiocarvalho777]

Hey @miguelsauza ,

What @avaysberg means by "web spring boot" is when you build your Spring Boot app as WAR and deploy it to a regular standalone servlet container, instead of running it as a Spring Boot micro-service out of its executable jar (with the container embedded to it).[

Running Spring Boot apps as WARs is documented in Spring Boot document.

[fabiocarvalho777]

Hello @avaysberg ,

Thanks for sharing a modified version of sample-app with bean validations. Based on that, I added Bean Validations to the starter sample-app and also to its integration tests (see #75). Everything is working as expected.

When it comes to a WAR version of sample-app, I assume everything works as expected as well, although I haven't tested it. I noticed that you didn't share your modified version of sample-app with bean validations as a WAR deployment. Could you share it please? Then I can test it and make sure I see the exact same behavior you are seeing. Also, make sure you follow the document below properly.

Running Spring Boot apps as WARs is documented in Spring Boot document.

[fabiocarvalho777]

I have just tested myself a WAR version of sample-app and I got the same wrong result you did, a 200 instead of a 400. I can see though resteasy-validator-provider-11 and hibernate-validator in the WEB-INF/lib folder, so I am not really sure yet what the root cause is.

[fabiocarvalho777]

This seems to be a legit bug. I have found out that the GeneralValidator implementation is not available for RESTEasy as a context resolver (resolver here should not be null, but in case of WAR deployments, it is).

I will do more investigation on it when I have time and figure out the root cause.

Feel free to investigate yourself and share your findings, or even send a PR, if you reach a solution.

[avaysberg]

Hi,
so, make it working for both cases. I prepare this configuration object and prepare the ValidatorContextResolver:

package com.sample.app;

import org.jboss.resteasy.plugins.validation.ValidatorContextResolver;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class ApplicationConfiguration {

    @Bean
    public ValidatorContextResolver validatorContextResolver() {
        return new ValidatorContextResolver();
    }
}

Thank you for your help.
I think, you can simple look for this class and if this not exist in class path than not create this bean for RESTEasy initialisation.

[avaysberg]

Today I spent some time and found out, that the classes with @Provider not load, but ValidatorContextResolver is annotated:
@Provider public class ValidatorContextResolver extends AbstractValidatorContextResolver implements ContextResolver<GeneralValidator> { }

[fabiocarvalho777]

Thanks @avaysberg , I am taking a look at it now.

[fabiocarvalho777]

I had to pause this for a while, too busy with work. I will come back to this as soon as possible.
