This is likely to be a misconception on my part when it comes to working with SpringBoot on FUSE EAP environments. I've been trying to deploy a service, which I've developed following the RedHat documentation and the archetypes/examples I've found online that mix Camel and SpringBoot, but to no avail.
From what I understand, when creating a connection to a JNDI datasource, which has been configured and tested in the EAP Fuse server, I can use the application.properties, or application.yml, to have the spring application autoconfigure the connection. In my case, it's required that I use #PersistenceContext to invoke the EntityManager, since the CRUD operations that the extending JpaRepository don't really cover the needs.
As per RedHat's documentation, FUSE 7.2 has been installed in EAP 7.1 and the POM is using the org.jboss.redhat-fuse.fuse-springboot-bom version 7.2.0.fuse-720020-redhat-00001.
I've tried using spring's autoconfiguration, a manual configuration declaring a #Configuration class, a manual configuration by declaring the database connection in the camel-context.xml file, and some other minor tests.
The errors vary depending on whether I try delpying the .jar or .jar.original, generated by having the spring-boot-maven-plugin with the repackage execution goal, errors obtained up to this point are:
NullPointer because EntityManager em is null (.jar.original)
java.lang.NoClassDefFoundError: org/springframework/boot/orm/jpa/EntityManagerFactoryBuilder (.jar.original, when there's a manual configuration of the datasource, be it in a #Configuration annotated java class, or in the camel-context.xml using Spring DSL)
java.lang.ClassNotFoundException: com.example.dao.genericDAOImpl (.jar with all dependencies packaged)
Here are snippets of my program, which include the POM, Application.java and the component which is trying to get the EntityManager, will be happy to provide more snippets if it's not enough/unclear.

As stated before, I've been getting numerous different errors depending on the options I've tried, and most of them clearly come down to misconfiguration, or not deploying correctly, I'm still somewhat inexperienced when it comes to SpringBoot and Camel, and different things I've read on the internet have created some confusion. Just to make sure, the pagination method, while very snipped out, should be working, if it had a not nulled EntityManager.
Here are a couple of the logs:

When deploying .jar.original (basically, just the java) with a manually configured DataSource and EntityManagerFactory. From what I understand, the service is expecting org.springframework.boot dependencies to exist on the server. After checking the modules, there is no org.springframework.boot module in the fuse layer. Is this intended?

Finally, when uploading the .jar.original using only the Spring autoconfigure, the EM is null, using Postman I get a status 500 and "No response available" when I consume the REST
java.lang.NullPointerException

The line makes reference to CriteriaBuilder paginationBuilder = em.getCriteriaBuilder(), or any other place where a EM method is invoked.
Thank you for your time! Any comment is appreciated...
There is no support for Spring Boot with Fuse EAP and the Camel subsystem. Hence why you do not see any org.springframework.boot dependencies in the Fuse module layer.
If you are going to deploy Camel Spring Boot applications into EAP, it's best you either disable the Camel subsystem for your deployment or avoid installing the subsystem entirely.
This is by no means a solution to the issue I was having, I believe this to be but a temporary patch on my code since the 7.4 version of Fuse will supposedly support SpringBoot 2.1.x or something of the like, but doing the following allowed me to create the database connection and move on with my life. I will not mark this as the acceptable answer, unless I'm told that this is the only way.
In the Application.java, I straight up disabled the SpringBootServletInitializer. Full disclosure, I straight up have no idea of the impact that doing this could have in an application, but the dependency was troubling while I was trying to deploy.
#ImportResource({"classpath:spring/camel-context.xml"})
#SpringBootApplication
public class Application {//extends SpringBootServletInitializer {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
I created a persistence.xml file where I configured the name of persistence unit and selected the package containing the entities (or listed them, both worked).
In the camel-context.xml I declared the following before the tag
<bean class="org.apache.camel.component.jpa.JpaComponent" id="jpa">
<property name="entityManagerFactory" ref="entityManagerFactory"/>
<property name="transactionManager" ref="jpaTxManager"/>
</bean>
<bean class="org.springframework.orm.jpa.JpaTransactionManager" id="jpaTxManager">
<property name="entityManagerFactory" ref="entityManagerFactory"/>
</bean>
<bean
class="org.springframework.orm.jpa.LocalEntityManagerFactoryBean" id="entityManagerFactory">
<property name="persistenceUnitName" value="PERSISTENCE UNIT NAME IN PERSISTENCE.XML"/>
</bean>
<bean class="org.apache.camel.spring.spi.SpringTransactionPolicy" id="requiredPolicy">
<property name="transactionManager" ref="jpaTxManager"/>
<property name="propagationBehaviorName" value="PROPAGATION_REQUIRED"/>
</bean>
I created a java class responsible for the creation of the EntityManager, it is very important that the class is #Stateless (EJB), and that the connection to the persistence unit is made static.
#Stateless
public class persistenceUnitEntityManagerImpl implements IfEntityManager{
private static EntityManager em;
static {
EntityManagerFactory entityManagerFactory = Persistence.createEntityManagerFactory("PERSISTENCE UNIT NAME");
em = entityManagerFactory.createEntityManager();
}
public void setEntityManager( EntityManager em ) {
persistenceUnitEntityManagerImpl.em = em;
}
public EntityManager getEntityManager() {
return persistenceUnitEntityManagerImpl.em;
}
}
In the beans where the database connection was needed, in my case, an #Component (should work just as well in a #Repository), I added the following:
private IfEntityManagerImpl IfEntityManager;
#PostConstruct
public void init() {
this.persistenceUnitEntityManagerImpl = new persistenceUnitEntityManagerImpl();
}
And whenever the EntityManager needs to be called, I can use persistenceUnitEntityManagerImpl.getEntityManager()
Just to make sure that the component isn't creating a new connection/entity manager/whatever, you can add a LOG to the #PostConstruct init, if your bean is a singleton (should be by default, I believe) you will never get that LOG or printline.

What it looks like you have configured oracle.jdbc.OracleDriver instead of oracle.jdbc.driver.OracleDriver
You can configure the following example :-
<spring:beans>

You need to configure and change as per your ip, username, password etc
Add commons-dbcp-1.2.2.jar or other version and ojdbc6.jar in your classpath as dependancy

The datasource bean on application context is defined as below
<bean id="myDatasource" class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiName" value="jdbc/myDS" />
</bean>
I would appreciate help. It seems something to do with classloading but I am not able to figure out.
try to specify the following properties to your datasource bean definition:
<bean id="myDatasource" class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiName" value="jdbc/myDS"/>
<property name="lookupOnStartup" value="false"/>
<property name="cache" value="true" />
<property name="proxyInterface" value="javax.sql.DataSource" />
</bean>
The proxyInterface solution worked for me on WAS 8.5.5 Liberty Profile.
On WAS 7, this also works as an alternate solution:
<jee:jndi-lookup id="WASdataSource" jndi-name="java:comp/env/jdbc/admt" />
<bean id="dataSource" class="org.springframework.jdbc.datasource.WebSphereDataSourceAdapter">
<property name="targetDataSource" ref="WASdataSource"/>
</bean>
I'm unit testing my DAOs using spring. I am using JPA + Hibernate.
For my tests i'm using the following hsqldb version:
<dependency>
<groupId>hsqldb</groupId>
<artifactId>hsqldb</artifactId>
<version>1.8.0.10</version>
<scope>test</scope>
</dependency>
And here's my persistence.xml for my unit tests:
<persistence-unit name="unit-test-pu" transaction-type="RESOURCE_LOCAL">
<properties>
<property name="javax.persistence.jdbc.driver" value="org.hsqldb.jdbcDriver"/>
<property name="javax.persistence.jdbc.user" value="sa"/>
<property name="javax.persistence.jdbc.password" value=""/>
<property name="javax.persistence.jdbc.url" value="jdbc:hsqldb:mem:testdb"/>
<property name="hibernate.dialect" value="org.hibernate.dialect.HSQLDialect"/>
<property name="hibernate.archive.autodetection" value="class"/>
<property name="hibernate.show_sql" value="true"/>
<property name="hibernate.use_sql_comments" value="true"/>
<property name="hibernate.format_sql" value="true"/>
<property name="hibernate.hbm2ddl.auto" value="create"/>
</properties>
</persistence-unit>
This is my test class:
#ContextConfiguration("/spring/test-context.xml")
#TestExecutionListeners({TransactionalTestExecutionListener.class})
#Transactional
public class BaseDaoTestCase extends AbstractJUnit4SpringContextTests {
#Autowired
private MockEntityDao dao;
#Test
public void testSave_success() {
MockEntity e = new MockEntity();
dao.save(e);
assertNotNull(e.getId());
}
}
Note: the idea is to test my DAOs against an in memory HSQLDB instance. Each test method runs within a transaction managed by spring.
Unfortunately, when i run this i get the following exception from hibernate:

The implementation of my DAO's save() method is as follows:
entityManager.persist(entity);
I'm using the following hibernate version:
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-entitymanager</artifactId>
<version>4.1.0.Final</version>
<scope>compile</scope>
</dependency>
Does anyone have a clue on what's going on?
I had similar Problem. After I update my dependencies (especially hsqldb) to:
<hibernate-core-version>4.1.5.Final</hibernate-core-version>
<spring.version>3.1.2.RELEASE</spring.version>
<hsqldb.version>2.2.8</hsqldb.version>
...
<dependency>
<groupId>org.hsqldb</groupId>
<artifactId>hsqldb</artifactId>
<version>${hsqldb.version}</version>
</dependency>
my problem is resolved.
Which mocking framework are you using? I'm just learning to work with mocks so this is just a wild guess but make sure you've done everything necessary to initialize the mock. Maybe the problem has something to do with how the test is being setup.
I'm having the same problem working with JPA + Hibernate + HSQLDB, but not spring.
Here is my code:
EntityManagerFactory emf = Persistence.createEntityManagerFactory("persistenceUnit");
EntityManager em = emf.createEntityManager();
EntityTransaction tr = em.getTransaction();
tr.begin();
em.persist(new MyEntity());
tr.commit();
em.close();
emf.close();
That throws me the same This function is not supported exception, but if I do it without the transaction, it doesn't. Like this:
EntityManagerFactory emf = Persistence.createEntityManagerFactory("persistenceUnit");
EntityManager em = emf.createEntityManager();
em.persist(new MyEntity());
em.close();
emf.close();
The problem now, is that I don't see the changes reflected on database.
