spring-data-jpa bean validation in junit tests

Question

In my recent work I've used spring-data-jpa to take advantage of provided repositories. When it came to integration tests I am unable to configure (I assume) spring context for testing and as a outcome bean validation doesn't work in my tests.

I am aware that I can inject validator, and unit test my annotations but it's not the case. I am writing integration tests and would like to test repositories with DB backed.

I have prepared simple project to show all necessary project files.

When I run tests, 2 are failing and I have no idea why, hibernate validator is present on class path.

Failed tests:   insertWrongEmail(com.example.core.data.jpa.UserRepositoryTest): Expected ConstraintViolationException wasn't thrown.
insertToShortPassword(com.example.core.data.jpa.UserRepositoryTest): Expected ConstraintViolationException wasn't thrown.

[..]

Thank you in advance for your help.

Java classes (I stripped of comments, geters, seters, equals, hashCode, toString etc.):

BaseEntity

package com.example.core.data.jpa;

import javax.persistence.*;

@MappedSuperclass
public abstract class BaseEntity {
    public static final String SEQUENCE = "global_seq";

    @Id
    @SequenceGenerator(name = SEQUENCE, sequenceName = SEQUENCE)
    @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = SEQUENCE)
    @Column(name = "id")
    private Long id;

    public Long getId() {
        return id;
    }
}

User

package com.example.core.data.jpa;

Solved

After answer from @gunnar, I have change test to flush persistence context after repository.save and it works as expected.

Changes to UserRepository

//inject entity manager
@PersistenceContext
private EntityManager entityManager;

//add flush after save in test method
@Test
public void insertWrongEmail() {
    //given
    user.setEmail("NOT_AN_EMAIL_ADDRESS");

    //when
    try {
        userRepository.save(user);
        entityManager.flush();

        fail("Expected ConstraintViolationException wasn't thrown.");

Solution 2

After recommendation from @andyb I have switched to eclipselink and tests work without flushing. That's the solution I will go with in my opinion it's better to switch implementation than using workaround.

Answer 1

I managed to reproduce the problem exactly described in the question locally, albeit after adding back the missing get/set functions and the UserRepository class :-)

After some digging I found two existing questions JPA ConstraintViolation vs Rollback and Hibernate not following JPA specifications when combined with Bean Validation API?

Both seem to conclude that Hibernate is not throwing the ConstraintValidationException correctly.

The outcome of the second question was a defect HHH-8028 - entityManager.persist not throwing ConstraintValidationException being raised against Hibernate.

To confirm this was the same issue, I switched to a simple @GeneratedValue and insertWrongEmail passed. insertToShortPassword was still failing but I put that down to a missing @Size(min = 6) on the password field. After adding that, all tests passed.

Reverting back to your configured @GeneratedValue I then swapped Hibernate for the EclipseLink persistence framework. Both tests passed which seems to confirm the discovery from the previous questions. The changes I made were:

pom.xml changes add the jpa artifact as described on the EclipseLink site

<dependency>
   <groupId>org.eclipse.persistence</groupId>
   <artifactId>org.eclipse.persistence.jpa</artifactId>
   <version>2.4.0</version>
   <scope>compile</scope>
</dependency>

test-context.xml changes

Switch to EclipseLinkJpaVendorAdapter

<bean id="jpaAdapter" class="org.springframework.orm.jpa.vendor.EclipseLinkJpaVendorAdapter"
    p:generateDdl="true" p:database="HSQL" />

Add eclipselink.weaving property, as detailed on EclipseLinkJpaVendorAdapter instead of HibernateJpaVendorAdapter issue

<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"
    p:dataSource-ref="dataSource" p:jpaVendorAdapter-ref="jpaAdapter" >
    <!-- existing configuration is identical -->
    <property name="jpaPropertyMap">
      <map>
        <entry key="eclipselink.weaving" value="false"/>
      </map>
    </property>
</bean>

User.java changes

I needed to add a default no-argument constructor. You might already have one in the full User.java class.
