Spring Boot JSR-303/349 configuration

Question

In my Spring Boot 1.5.1 application I\'m trying to configure support of JSR-303 / JSR-349 validation.

I have added a following annotations @NotNull @S

Answer 1

Move your validation to interface, as follows:

import javax.validation.Valid;
import javax.validation.constraints.NotNull;
import javax.validation.constraints.Size;

public interface DecisionDao {

     Decision create(@Valid @NotNull @Size(min = 1) String name,
            String description, String url, String imageUrl);
}

Annotate your DecisionDaoImpl with @Validated, as follows:

import org.springframework.stereotype.Service;
import org.springframework.validation.annotation.Validated;

@Service
@Validated
public class DecisionDaoImpl extends BaseDao implements DecisionDao {

    @Override
    public Decision create(String name,
            String description, String url, String imageUrl) {
        System.out.println(name);
        return new Decision();
    }

}

Modify your test case to verify for javax.validation.ConstraintViolationException using assertj or ExpectedException, as follows:

import static org.assertj.core.api.Assertions.assertThatExceptionOfType;

import javax.validation.ConstraintViolationException;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringRunner;
import org.springframework.validation.beanvalidation.MethodValidationPostProcessor;

@ContextConfiguration(classes = { TenantTest.Config.class })
@RunWith(SpringRunner.class)
public class TenantTest {

    @Autowired
    private DecisionDao decisionDao;

    @Rule
    public ExpectedException expectedException = ExpectedException.none();

    @Test
    public void testCreateDecisionUsingAssertj() {
        assertThatExceptionOfType(ConstraintViolationException.class)
                .isThrownBy(
                        () -> decisionDao.create(null,
                                "Root decision 1 description", null, null));
    }

    @Test
    public void testCreateDecision() {
       expectedException.expect(ConstraintViolationException.class);
       decisionDao.create(null, "Root decision 1 description", null, null);
    }

    @Configuration
    public static class Config {
        @Bean
        public MethodValidationPostProcessor methodValidationPostProcessor() {
            return new MethodValidationPostProcessor();
        }

        @Bean
        public DecisionDao decisionDao() {
            return new DecisionDaoImpl();
        }
    }
}

Make sure you have hibernate-validator in your classpath along with @StanislavL answer:

    org.hibernate
    hibernate-validator

And an optional dependency for org.assertj.core.api.Assertions.assertThatExceptionOfType, as:

     org.assertj
     assertj-core
     3.3.0
     test
