EntityManager cannot use persist to save element to database - java

I met the problem of persisting element to database using EntityManager. Based on the answers I found, I tried those 4 ways in my DaoJpa to do such thing but still failed. Here I attached the four ways I tried:
Code in Controller part:
#Transactional
SmartProduct smartProduct = new SmartProduct();
smartProduct.setName("Dove Soap");
smartProductDao.persist(smartProduct);
1.
DaoJpa:
#Transactional
public void persist(SmartProduct smartProduct) {
entityManager.persist(smartProduct);
Doesn't work!
2.
#Transactional
public void persist(SmartProduct smartProduct) {
entityManager.persist(smartProduct);
entityManager.flush();
Exception I got: no transaction is in progress
3.
#Transactional
public void persist(SmartProduct smartProduct) {
EntityTransaction emTransaction = entityManager.getTransaction();
emTransaction.begin();
entityManager.persist(smartProduct);
emTransaction.commit();
entityManager.close();
Exception I got:
Not allowed to create transaction on shared EntityManager - use Spring
transactions or EJB CMT instead
4.
#Transactional
public void persist(SmartProduct smartProduct) {
EntityManagerFactory emf = Persistence.createEntityManagerFactory("persistenceUnit");
EntityManager em = emf.createEntityManager();
EntityTransaction etx = em.getTransaction();
etx.begin();
em.persist(smartProduct);
etx.commit();
em.close();
emf.close();
Exception I got:
The application must supply JDBC connections
Could someone help me figure out the problem please? Many thanks in advance!
Many thanks JustinKSU's help. I add the annotation in Spring context and then it solved!
Here is the previous version of my Spring context:
<bean class="org.springframework.orm.jpa.JpaTransactionManager" id="transactionManager">
<property name="entityManagerFactory" ref="entityManagerFactory" />
</bean>
<tx:annotation-driven mode="aspectj" transaction-manager="transactionManager" />
<bean class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean" id="entityManagerFactory">
<property name="persistenceUnitName" value="persistenceUnit" />
<property name="dataSource" ref="dataSource" />
</bean>
After added the
<tx:annotation-driven />
it works:
<tx:annotation-driven />
<bean class="org.springframework.orm.jpa.JpaTransactionManager" id="transactionManager">
<property name="entityManagerFactory" ref="entityManagerFactory" />
</bean>
<tx:annotation-driven mode="aspectj" transaction-manager="transactionManager" />
<bean class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean" id="entityManagerFactory">
<property name="persistenceUnitName" value="persistenceUnit" />
<property name="dataSource" ref="dataSource" />
</bean>

To enable #Transactional in your Spring context you should have the following:
Appropriate for your version of Spring:
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd">
Enable the annotations:
<tx:annotation-driven />
Declare your transaction manager injecting your entity manager:
<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
<property name="entityManagerFactory" ref="entityManagerFactory" />
</bean>

If you still have this problem and all the configurations are ok, please make sure that the #Transaction annotated method is public, not protected in order to be identified/managed by the transaction manager.

Answer
Based on the coments given below by M. Denium; I did following changes and it worked.
1) Used HibernateTransactionManager instead of DataSourceTransactionManager
<bean id="transactionManager"
class="org.springframework.orm.hibernate5.HibernateTransactionManager">
<property name="sessionFactory" ref="mySessionFactory" />
</bean>
2) In removed mode="aspectj"
so it looks like
<tx:annotation-driven proxy-target-class="true" transaction-manager="transactionManager" />
I see to problems with your configuration
You are not using the proper PlatformTransactionManager
Unless you are using load- or compile time weaving I doubt the mode="aspectj" is really correct.
First you need to use the PlatformTransactionManager that supports your persistence technology, as you are using Hibernate 5, you need to use the org.springframework.orm.hibernate5.HibernateTransactionManager instead of the DataSourceTransactionManager. (the latter is for application that only do plain JDBC transactions).
From the <tx:annotation-driven /> remove the mode="aspectj" as I suspect you are actually not using full blown AspectJ but are relying on plain Spring to do this for you.
Pro Tip: Instead of using HibernateTemplate, which isn't recommended anymore since Hibernate 3.0.1, just use plain SessionFactory with getCurrentSession instead. This will allow you to write plain Hibernate daos. As suggested in the reference guide.

#Transactional for any Exceptions in Spring

I am looking using #Transactional on one of the Service methods. However when an exception occurs, the transaction is not getting rolled back. I tried the same with #Transactional(rollbackFor=Exception.class). My code as follows:-
#Override
#Transactional(rollbackFor=Throwable.class)
public boolean addUser(User user) throws Exception{
boolean userAdded = userDao.addUser(user);
boolean userRegistrationRecorded = userDao.recordUserRegistraionDetails(user);
return true;
}
I read lot of posts and every one says that Spring handles only RuntimeExceptions and not checked Exceptions other than RmiException. I need a solution that works for any kind of Exception. Some one suggested me to write own annotation, where as others suggested of having a TransactionManager as part of applicationContext.xml file. A detailed solution will definitely help me.
By the way I am using Spring JdbcTemplate. The strange thing I observe is though the Exceptions raised by Spring are RuntimeExceptions the transaction is not getting rolled back. I am trying to raise an Exception by adding the same User in the above scenario.
My applicationContext.xml is as follows:-
<context:component-scan base-package="org.chaperone.services.security.*" />
<context:annotation-config />
<bean id="transactionManager"
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource" />
</bean>
<bean id="propertyPlaceholderConfigurer"
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="systemPropertiesModeName" value="SYSTEM_PROPERTIES_MODE_OVERRIDE" />
<property name="searchSystemEnvironment" value="true" />
</bean>
<bean id="dataSource"
class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="com.mysql.jdbc.Driver" />
<property name="url" value="${DATABASE_URL}" />
<property name="username" value="${DATABASE_USER_NAME}" />
<property name="password" value="${DATABASE_PASSWORD}" />
</bean>
<bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">
<property name="dataSource" ref="dataSource" />
</bean>
The ease-of-use afforded by the use of the #Transactional annotation is best illustrated in this link
you have to add :
<tx:annotation-driven transaction-manager="transactionManager" />

I'm not using persistence.xml because I read in some places its not necessary in Spring 4 with Hibernate.
When I start the server it still loading and don't start in 45s (nor 180s) in Tomcat7.
I create a factory of EntityManager to use in my project:
package com.nassoft.erpweb.factory;
import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import javax.persistence.Persistence;
import javax.persistence.PersistenceUnit;
public class ConnectionFactory {
#PersistenceUnit
private static EntityManagerFactory entityManagerFactory;
public static EntityManager getEntityManager(){
if (entityManagerFactory == null){
entityManagerFactory = Persistence.createEntityManagerFactory("ERPWeb");
}
return entityManagerFactory.createEntityManager();
}
}
I think my configuration is not correct, but I don't found any places with a good text about it.
Can someone help-me?
Edited.
Problem solved!
First: I applied Dependency Injection in each controller to bring the DAOs with IoC.
Second: I use the annotation #Repository to create a repository in each DAO that will receive my databases methods.
Third: I created the EntityManage in this way for each DAO:
#PersistenceContext
private EntityManager manager;
This is not a complete answer. I"m just pointing you to a direction.
Spring cannot find the ConnectionFactory class of yours, so it will not inject the entityManagerFactory. Its not required for you to again create a singleton for passing the entityManager, so no ConnectionFactory class is required. Spring will do it for you by injecting into the DAO or Controller etc., for example you have the following DAO that gets the data.
#Service
public class SomeDAO {
#AutoWire -- i'm not sure what you call for the entityManager.
private static EntityManagerFactory entityManagerFactory;
}
There is more info here. Instead of #autowiring he is using manual injection. I your case ,you can try with autowiring.
Also make sure that you have these classes in the <spring:component-scan /> path of the application context file or else the spring wont be able to recognize and inject the entity manager.

Spring IllegalStateException: A JTA EntityManager cannot use getTransaction()

So after a big refactoring project, I am left with this exception and am unsure as how to correct it. It's dealing with some code that I did not write and I am unfamiliar with how it all works. There are other questions out there dealing with this exception, but none seem to fit my situation.

Thanks for all the help!
The problem is your configuration. You have hibernate configured for JTA.
<property name="hibernate.transaction.manager_lookup_class" value="org.hibernate.transaction.WebSphereExtendedJTATransactionLookup" />
Whereas you are using local transactions instead of distributed transactions.
at org.springframework.orm.jpa.JpaTransactionManager.doBegin(JpaTransactionManager.java:380)
You have 2 possible solutions
remove the JpaTransactionManager and replace it with a JTA transaction manager
remove the remove the hibernate.transaction.manager_lookup_class from the hibernate settings.
If you don't really need distributed transactions option 2 is the easiest, if you need distributed transactions simply adding <tx:jta-transaction-manager /> will setup a proper JTA tx manager for your environment. Remove the definition for the JpaTransactionManager.
Update:
Your configuration is flawed in 2 ways.
Your EntityManager configuration already contains a jndi lookup for the datasource, which you override in your applicationContext by configuring a local datasource
You have both a <tx:jta-transaction-manager /> and JpaTransactionManager which one do you want to use? At the moment the latter is overriding the first one.
Create 2 seperate configurations one for local testing and one for production using JTA en JNDI lookups. (Preferable your testing code only overrides the beans necessary).
Use WebSphereTransactionManagerLookup for the transaction manager lookup in Hibernate
<property name="hibernate.transaction.manager_lookup_class" value="org.hibernate.transaction.WebSphereTransactionManagerLookup" />
and remove your current transaction manager and replace it with the WebSphereUowTransactionManager.
<tx:annotation-driven/>
<bean id="transactionManager" class="org.springframework.transaction.jta.WebSphereUowTransactionManager"/>
for your transaction manager lookup in Spring.
See IBM Websphere and Spring docs
for more in depth documentation.

What transaction manager should I use for JBDC template When using JPA ?

I am using standard JPA transaction manager for my JPA transactions. However, now I want to add some JDBC entities which will share the same 'datasource'. How can I make the JDBC operations transactional with spring transaction? Do I need to switch to JTA transaction managers? Is it possible to use both JPA & JDBC transactional service with same datasource? Even better, is it possible to mix these two transactions?
UPDATE:
#Espen :
I have a dao extended from SimpleJdbcDaoSupport which uses getSimpleJDBCTemplate.update to insert a database row. When a RuntimeException is thrown from the service code, the transaction never rolls back when using JPATransactionManager. It does rollback when using DatasourceTransactionManager. I tried to debug the JPATransactionManager and seems that it never performs rollback on underlying JDBCConnection(I guess due to the fact that the datasource is not necessarily has to be JDBC for JPA). My configuration setup are exactly like you explained here.
Here are my test codes:

}
NOTE: the code works as expected when using DatasourceTransactionManager
UPDATE - 2:
Ok I have found the root cause of the problem. Thanks to Espen.
My entity manager configuration was like this(copied from spring pet-clinic app):
<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="dataSource" ref="dataSource"/>
<property name="persistenceXmlLocation"
value="classpath:/persistence-test.xml" />
<property name="persistenceProvider">
<bean class="org.hibernate.ejb.HibernatePersistence" />
</property>
</bean>
Then I changed it to like this:
<bean id="entityManagerFactory"
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">

Now everything seems to be working! Can anyone explain the difference between these two approach ?
It's possible to mix JPA and JDBC code in the same transaction using the JpaTransactionManager.
A snippet from Spring 3's JavaDoc:
This transaction manager also supports
direct DataSource access within a
transaction (i.e. plain JDBC code
working with the same DataSource).
This allows for mixing services which
access JPA and services which use
plain JDBC (without being aware of
JPA)!
You should be aware though that JPA caches the queries and executes all of them at the end of a transaction. So if you want to persist some data inside a transaction with JPA and then retrieve the data with JDBC, it will not work without explicitely flushing the JPA's persistence context before you attempt to retreive it with JDBC code.
A code example that asserts with JDBC code that the JPA code deleted a row inside a transaction:
#Test
#Transactional
#Rollback(false)
public void testDeleteCoffeeType() {
CoffeeType coffeeType = coffeeTypeDao.findCoffeeType(4L);
final String caffeForte = coffeeType.getName();
coffeeTypeDao.deleteCoffeeType(coffeeType);
entityManager.flush();
int rowsFoundWithCaffeForte = jdbcTemplate
.queryForInt("SELECT COUNT(*) FROM COFFEE_TYPES where NAME = ?",
caffeForte);
assertEquals(0, rowsFoundWithCaffeForte);
}
And if you prefer to use the JpaTemplate class, just replace the entityManager.flush() with jpaTemplate.flush();
In response to Sajids' comment:
With Spring you can configure a transaction manager that supports both JPA and JDBC like this:
<tx:annotation-driven transaction-manager="transactionManager" />
<!-- Transaction manager -->
<bean id="transactionManager" class="org.springframework.orm.jpa
.JpaTransactionManager">
<property name="entityManagerFactory" ref="entityManagerFactory" />
</bean>
and Annotation-Driven version
#Bean
public JpaTransactionManager transactionManager(EntityManagerFactory emf) {
JpaTransactionManager jpaTransactionManager = new JpaTransactionManager();
jpaTransactionManager.setEntityManagerFactory(emf);
return jpaTransactionManager;
}
In order to make it work, the JDBC queries must be executed with the JdbcTemplate or the SimpleJdbcTemplate class. In your case with the DAO that extends the SimpleJdbcDaoSupport, you should use the getSimpleJdbcTemplate(..) method.
And finally to let two DAO methods participate in the same transaction, call both DAO methods from a service class metho annotated with #Transactional. With the <tx:annotation-driven> element in your config, Spring will handle the transaction for you with the given transaction manager.
On the business layer:
public class ServiceClass {..
#Transactional
public void updateDatabase(..) {
jpaDao.remove(..);
jdbcDao.insert(..);
}
}
Edit 2:
Then something is wrong. It works for me exactly as specified in the Javadoc.
Does your entity manager has a datasource property like my bean below? It will only work as long you're injecting the same datasource into the entity manager and your extended JpaDaoSupport classes.
<bean id="entityManagerFactoryWithExternalDataSoure" primary="true"
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="jpaVendorAdapter">
<bean class="org.springframework.orm.jpa.vendor
.HibernateJpaVendorAdapter" />
</property>
<property name="jpaProperties">
<value>
hibernate.format_sql=true
</value>
</property>
</bean>
I've not really worked this out in detail yet as I've not mixed both JDBC and JPA but if you get your JDBC connection for an XA datasource then they are JTA transaction. So if you run your code in Stateless session bean for example with transaction turned on, then you automatically get both your Entities and JDBC managed by JTA.
EDIT
Here is an example code from Servlet
private #Resource DataSource xaDatasource;
private #Resource UserTransaction utx;
private #PersistenceUnit EntityManagerFactory factory;
public void doGet(HttpServletRequest req, HttpServletResponse res) ... {
utx.begin();
//Everything below this will be in JTA
Connection conn = xaDatasource.getConnection();
EntityManager mgr = factory.createEntityManager();
//Do your stuff
...
utx.commit();
}
Disclaimer: Code not tested.
Just realize this is not Spring but I'll leave it up anyway
