The annotation Propagation.NEVER doesn't work

The annotation Propagation.NEVER doesn't work - java

Programmers! I don't understand how doeas the propagation attribute work in the #Transactional annotation. Please, help)

Service class:
#Service
public class BookManager implements IBookManager {
#Autowired
private SessionFactory sessionFactory;
#Override
#Transactional(propagation = Propagation.REQUIRES_NEW)
public void method1() {
Session session = sessionFactory.getCurrentSession();
Book book = (Book) session.load(Book.class, 1);
System.out.println("first: " + book.getTitle());
method2();
}
#Override
#Transactional(propagation = Propagation.NEVER)
public void method2() {
System.out.println("hello");
}
}
I expect that the method method2() throws an exception, as it is annotated with Propagation.NEVER. But this is not happening.

Why it doesn't work?
Thanks :)

Transactions in Spring are proxy-based: when a bean A calls a transactional bean B, it actually calls a method of a dynamic proxy, which deals with the opening of the transaction, then delegates to the actual bean B, then deals with the commit/rollback of the transaction.
If you call a method2 from a method1 of a single bean A, your call is not intercepted by the transactional proxy anymore, and Spring is thus completely unaware that method2() has been called. So nothing can check that there is no transaction.
Put the method2 in another bean, injected in BookManager, and everything will work as expected.

Unable to run basic hibernate 5 program

I am trying to run the program given in hibernate tutorial(basic).But I am facing error. Surprisingly, there are very few error logs displayed in the console. If anyone can show me where I am going wrong, I will be grateful. I have spent lot of time trying to resolve it before posting it here.

I have made some changes to the hibernate.cfg.xml and it started working.The modified xml is as below :
<hibernate-configuration>
<session-factory>
<!-- Database connection settings -->
<property name="connection.driver_class">oracle.jdbc.driver.OracleDriver</property>
<property name="connection.url">jdbc:oracle:thin:#localhost:1521:XE</property>

<property name="hbm2ddl.auto">create</property>
<mapping resource="org/hibernate/tutorial/hbm/Event.hbm.xml"/>

The change I done in this xml is modifying the connection url :
<property name="connection.url">jdbc:oracle:thin:#localhost:1521:XE</property>

Generic class Implementation for a SpringData & QueryDSL Service

I have a bunch of service classes that have repositories that extends JpaRepository and QueryDslPredicateExecutor.
The methods in the service classes are identical except for the entity that it processes. I am trying to create
a generic service class but I am getting a "Injection of resource dependencies failed; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [pkg.BaseRepository] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency".
Below are my classes:
//BaseRepository.java
#NoRepositoryBean
public interface BaseRepository<T> extends JpaRepository<T, Long>, QueryDslPredicateExecutor<T> {}
//RegionRepository.java
#Repository
public interface RegionRepository<Region> extends JpaRepository<Region, Long>, QueryDslPredicateExecutor<Region> {}
//ProvinceRepository.java
#Repository
public interface ProvinceRepository<Province> extends JpaRepository<Province, Long>, QueryDslPredicateExecutor<Province> {}
...
and many more XxxRepository interfaces
//AbstractBaseService.java
public abstract class AbstractBaseService<T>{
#Autowired
private BaseRepository<T> repository;
public void add(T entity) {
System.out.println("Adding entity " + entity.getClass());
}
public T retrieve(Long id) {
System.out.println("Retrieving region with dbId = " + id);
return repository.findOne(id);
}
public List<T> findAll() {
return repository.findAll();
}
...
//some other methods
}
//RegionService.java
#Service("regService")
public class RegionService extends AbstractBaseService<Region> {}
//ProvinceService.java
#Service("provService")
public class ProvinceService extends AbstractBaseService<Province> {}

Is there a way to make the AbstractBaseService work as I envision above so that I don't have to create the one Service class with the same implementation as AbstractBaseService for each of my entities (Region, Province, User, Vehicle.... etc)?
Any help would be greatly appreciated.
Thanks in advance,
Mario

//RegionRepository.java
#Repository
public interface RegionRepository<Region> extends JpaRepository<Region, Long>, QueryDslPredicateExecutor<Region> {}
^^^^^^ Here you are actually making a new Type Variable, which is bounded to Object.
You are making new Type Variables, this actually hides the class name you are making the Repository for.

I was finally able to make my original post work. What were missing were the annotation #NoRepositoryBean on the BaseRepository.java interface and #Repository annotations on RegionRepository/ProvinceRepository interfaces as edited above.

unable to persist entity in spring tests with JpaTransactionManager

I'm trying to persist an entity using. My test case works (data are persisted in db) when I handle my transaction myself.
public User saveUser(User user) {
getEm().getTransaction().begin();
getEm().persist(user);
getEm().getTransaction().commit();
return user;
}
(entity manager comes from a template class which my DAO class extends)
It stops persisiting data when I configure spring to handle transactions.

As you can see from the stacktrace, transaction seems to be started and finished, but no sql inserts are produced and no data are inserted into db (data rollback is set to false)
I've tried force flushing data after persist() but spring managed transaction seems to be finished by then.
I've looked for a similar issue on forums but none works.
I can provide some more code if necessary.
I'm using Spring 3.1.2 and Hibernate 4.1.6.Final
update:
DAO: (#Transactional annotation is put here instead on service layer temporarily)
#Repository
public class JpaUsersDAO extends JpaDAOTemplate<User> implements UsersDAO {
public JpaUsersDAO(EntityManagerFactory factory) {
super(factory.createEntityManager(), User.class);
}
#Transactional
public User saveUser(User user) {
getEm().persist(user);
return user;
}
}
DAOTemplate:
public abstract class JpaDAOTemplate<T extends Serializable> {
private EntityManager em;
private Class<T> clazz;
public JpaDAOTemplate(EntityManager em, final Class<T> clazz) {
this.em = em;
this.clazz = clazz;
}
public EntityManager getEm() {
return em;
}
public T getById(Integer id) {...}
...
}
bean definition:
<bean id="usersDao"
class="pl.package.user.dao.impl.JpaUsersDAO">
<constructor-arg ref="entityManagerFactory" />
</bean>
It seems that the transaction is lost somewhere after selects and before calling getEm().persist() - org.hibernate.ejb.TransactionImpl#tx is null when calling persist() but it was org.hibernate.engine.transaction.internal.jdbc.JDBCTransaction before the call (when sql select statements calls were made)

Final update:
Problem was in the way I injected EntityManagerFactory to my DAO. I used applicationContext.xml configuration file to inject it (this way EMF does not participate in transaction). To have it working I changed my DAO class to:
#Repository
public class JpaUsersDAO extends JpaDAOTemplate<User> implements UsersDAO {
#PersistenceContext
private EntityManager em;
...
}

You are using Spring 3.0.
I am not clear your coding public User saveUser(User user) method. Even If you use Spring 3.0, you handel the transaction your self(Bean Management Transaction).
It just need to use #Transactional(propagation = Propagation.REQUIRED) annotation. Change propagation type based on your process.
Example DAO :
GroupDAO.java
#Repository("GroupDAO")
public class GroupDAO {
#PersistenceContext
protected EntityManager em;
#Transactional(propagation = Propagation.REQUIRED)
public void insert(Group group) {
try {
em.persist(group);
em.flush();
} catch (PersistenceException pe) {
}
}
}

Please tell me what is an issue in my code?
Thanks in advance..

In User.hbm.xml you have to use type="java.lang.String" (with a big 'S'). That's it.

AS I understand the problem in your code was caused by your User.hbm.xml mapping file. To be more precised by type="string" attribute of composite-id tab.
As I understand you don't need to put type attribute obligatory so try to skip it at all; hibernate should detect it automatically. I'm not sure in last sentece because I have not used composite keys, but there are a lot of examples where peoples don't define type explicitly.

Hmmm, in your mapping file you have
<key-property name="businessUnit" column="BusinessUnit" type="string"/>
<key-property name="userID" column="UserID" type="string"/>
That should be ...type="java.lang.String"... instead, but most likely you really don't need it - Hibernate will make a (usually very good) educated guess.
Cheers,

Hibernate use the reflection to determine the mapping type at runtime.
It seems your mapping is correct, But if you still getting the same problem.
I will suggest you to remove the type attribute for the time being test, from all the String type properties such as email,businessUnit,userId
try this way for all the String type properties
<property name="email">
<column name="Email"/>
</property>
or you can try with java.lang.String also
<property name="email" type="java.lang.String">
<column name="Email"/>
</property>

Both "string" and "java.lang.String" are aliases for org.hibernate.type.StringType, so either should work in terms of naming types.
I am actually not so sure the problem is in the mapping for User. That mapping looks fine. Based on that exception I would more expect that somewhere you have
<composite-id ... class="string">
or
<component ... class="string">
or something like that.

<composite-id name="userPK" >
<key-property name="businessUnit" column="BusinessUnit" type="String"/>
<key-property name="userID" column="UserID" type="String"/>
</composite-id>
try with changing string to String

I'm certain the url details and credentials are correct for the database, can anyone think of any other reasons?
It looks like it's trying to access the information_schema db, but in my XML I have set the db it should look at...
<beans:bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
destroy-method="close">
<beans:property name="driverClassName" value="com.mysql.jdbc.Driver" />
<beans:property name="url" value="jdbc:mysql://localhost/assessme" />

<beans:property name="password" value="toor" />
</beans:bean>
Thanks,

I'm extracting the correct answer to this question from the comments of a different answer.
This Exception gets thrown because your used dialect doesn't match the database.
In your configuration you use
<beans:prop key="hibernate.dialect">org.hibernate.dialect.H2Dialect</beans:prop>
although you're accessing a MySQL database. You should use a MySQL dialect instead. E.g.
<beans:prop key="hibernate.dialect">org.hibernate.dialect.MySQL5InnoDBDialect</beans:prop>

Look at your error:
ERROR: org.hibernate.tool.hbm2ddl.SchemaUpdate - could not get database metadata
com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Unknown table 'sequences' in information_schema
You are mapping your MySQL to information_schema which is system database in MySQL and this database does not contain sequances table,
BTW, of the record, you need to take into consideration that MySQL does not have "CREATE Sequance" command.

let you add this in the application.properties file
spring.jpa.database-platform=org.hibernate.dialect.MySQL5InnoDBDialect
the the error will be disappeared.
