anybody has idea why hibernate is not creating tables in my example ?
Here's my web.xml - http://pastebin.com/ZaseSaBS
mvc-dispatcher-servlet.xml - http://pastebin.com/LbdxMSAb
applicationContext.xml - http://pastebin.com/bAHMaVNX
console logs - http://pastebin.com/tTZZbxkX
I have similiar project with almost the same configuration and everything seems to run just fine on the other project. Any ideas why it's not creating tables here?
I've one test enity in com.calculator.enity with #Entity #GeneratedValue annotations, i have it listed in persistence.xml file. There's also JpaRepository for this entity in com.calculator.repository
It looks like your persistence configuration is not properly done. Use this sample persistence configuration as per your requirement. This is working fine for me.

When using jooq and HikariCP DataSource (Autowired) in a Spring Restful API i get the problem, that jooq is somehow not releasing the DataSource.
Some Code:
#Autowired
private DataSource dataSource;
//Further down
DSLContext create = DSL.using(dataSource, SQLDialect.MYSQL);
After using this repository/call two or three times i have too many connections open.

Ok i fixed the problem:
#Autowired
private DataSource dataSource;
//Further down
Connection con=dataSource.getConnection();
DSLContext create = DSL.using(con, SQLDialect.MYSQL);
//Execute code here
con.close();
So instead of directly using the DataSource i used a connection and released it.
Hi I'm having a problem setting up hibernate on spring. I was able to make it work but it creates a lot of session on the database. From What i have notice it creates session for every bean on my spring.xml. Since I have 6 beans declared I also have 6 session on the database on application start Here is my code

You need to use transactionManager to manage session for you.
Add the following lines of code to your spring.xml
....
<tx:annotation-driven transaction-manager="transactionManager" />
<bean id="transactionManager"
class="org.springframework.orm.hibernate4.HibernateTransactionManager">
<property name="sessionFactory" ref="yourSessionFactory" />
</bean>
....
Then you have to annotate your service impl classes #Transactional("transactionManager") to make transactionManager managing transactions through session
#Transactional("transactionManager")
public class PServiceImpl implements PServiceImpl{
....
Just an advice you can replace XML config for the DI by annotations to make it easy
in spring.xml, remove all your beans declarations (xxservice and xxxdao) and replace them by: <context:component-scan base-package="put here the package where your services and daos are lacated" />
your service must look like this :
#Service
#Transactional("transactionManager")
public class XXXServiceImpl implements XXXService{
#Autowired
private XXXDAO xxxDAO;
...
}
And your dao must look like :
#Repository
public class XXXDAOImpl implements XXXDAO {
#Autowired
private SessionFactory sessionFactory;
...
}
One more thing, add the tx schema in your file config header, your spring.xml should look like this :
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"

Why do you want hibernate to manage the pool? The way it is setup in the second case is the correct way to configure dataSource & hibernate session factory with spring. This will work correctly with spring transaction management.
When you pass the dataSource as a parameter to the sessionFactoryBean the hibernate properties related to the dataSource configuration will be ignored. If you insist upon hibernate managing the pool you can try by removing the dataSource property injection in the AnnotationSessionFactoryBean. The driverClass, jdbcURL etc needs to now be specified as a part of hibernate properties.
From the spring javadoc.
Set the DataSource to be used by the SessionFactory. If set, this will
override corresponding settings in Hibernate properties. If this is
set, the Hibernate settings should not define a connection provider to
avoid meaningless double configuration.
http://static.springsource.org/spring/docs/2.5.x/api/org/springframework/orm/hibernate3/AbstractSessionFactoryBean.html#setDataSource(javax.sql.DataSource)
You can either let spring manage the connection pool (by way of configuring the datasource bean and passing it to sessionFactory) or let hibernate manage it completely. Half & half will not work.
