Configure hibernate in spring application - java

I have successfully configured hibernate and I can run transactions but only from the psvm of the DAO class. I want to configure it with my spring app using the same configuration file i.e. hibernate.cfg.xml.
How can I do this? Most tutorials I've read simply neglect the hibernate configuration file.

You can add this code to you xml file to configure hibernate.
<!-- Hibernate Related Configuration. -->
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
<property name="driverClassName" value="org.postgresql.Driver"/>
<property name="url" value="jdbc:postgresql://192.168.1.9:5432/dbname"/>
<property name="username" value="postgres"/>
<property name="password" value="pwd"/>
<property name="validationQuery" value="SELECT 1"/>
</bean>
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
<property name="dataSource" ref="dataSource"/>
<property name="packagesToScan" value="com.domain"/>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.PostgreSQLDialect</prop>
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.format_sql">true</prop>
<prop key="hibernate.generate_statistics">true</prop>
</props>
</property>
</bean>
<!-- Transaction Manager -->
<bean id="txManager"
class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory" />
</bean>
<tx:annotation-driven transaction-manager="txManager" />

The hibernate.cfg.xml file is specified for the LocalEntityManagerFactoryBean, along with your DataSource
<bean id="entityManagerFactory"
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="persistenceXmlLocation" value="classpath*:META-INF/hibernate.cfg.xml" />
<property name="dataSource" ref="dataSource" />
</bean>
Here you can find an example of a Spring XML configuration containing some Hibernate configuration

Javax Persistence Error : Unknown Entity com.samplewebentities.Customer

I'm trying to persist an entity using EntityManagerFactory defined in my bean. The function looks like this:
private BaseMasterEntity saveEntity(BaseMasterEntity entity){
EntityManagerFactory emf = (EntityManagerFactory)context.getBean("entityManagerFactory");
EntityManager sf = emf.createEntityManager();
sf.getTransaction().begin();
sf.persist(entity);
sf.getTransaction().commit();
sf.close();
return entity;
}
The problem here is when it persists it cannot find the entity. The entity has #Entity defined clearly with the javax.persistance annotation. This is how my context file looks btw:
<property name="driverClassName" value="oracle.jdbc.driver.OracleDriver" />
<property name="url" value="*my jdbc setting*" />
<property name="username" value="hr" />
<property name="password" value="hr" />
</bean>
<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
<property name="entityManagerFactory" ref="entityManagerFactory" />
</bean>
<bean id="entityManagerFactory"
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="jpaVendorAdapter" ref="hibernateJpaVendorAdapter" />
<property name="packagesToScan"
value="classpath*:com.samplewebentities"></property>
<property name="jpaProperties">

</props>
</property>
</bean>
<bean id="hibernateJpaVendorAdapter"
class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter" />
<tx:annotation-driven transaction-manager="transactionManager" />
If it helps, the classpath*:com.samplewebentites is a different component (The application is a combination of many different components/projects: Using SCA here).
No need for classpath

spring Hibernate Multi SessionFactories and TransactionManager

i am a newbie to spring and hibernate..Here in my scenario, i am building an application where it can connect to different environments Db's(devl,qual,prod) based on the environment selected by the user..For this I am making multiple SessionFactory beans and distinguishing them using #Qualifier in DAO classes based on the env selected by the user..
Here i am struck at, how to configure multi-TransactionManagers if they are required or not in my case and how to deal with the code if the multi-TransactionManagers are not required..?
So I was not sure of how to use different TransactionManagers per env, for the same save method which will save the user form data in the DB..Below is my spring .xml file and the DAO class code which is used to distinguish the sessionFactory w.r.t env..
Help needed in configuring multiple TransactionManagers or can I discard the use of TransactionManager and simply distinguish the transaction with Hibernate session(beginTransaction)..!!
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">

{
getCurrentSession(targetEnv).getTransaction().begin();
}
#Autowired
#Qualifier("DevlSessionFactory")
private SessionFactory devlSessionFactory;
#Autowired
#Qualifier("prodSessionFactory")
private SessionFactory prodSessionFactory;
protected final Session getCurrentSession(String targetEnv)
{
if(targetEnv!=null && !"".equals(targetEnv) && targetEnv.equals("Devl"))
{
return devlSessionFactory.getCurrentSession();
}
else if(targetEnv!=null && !"".equals(targetEnv) && targetEnv.equals("PROD"))
{
return prodSessionFactory.getCurrentSession();
}
return null;
}
Appreciate the help...

Spring Cfg+Hibernate Cfg and Anotations

I want to make a test with HQL but the mapping tables is with Annotations.

When I run a list, I get that you do not find the hibernate cfg:
hibernate.cfg.xml not found
I just want to list a mapped class with annotations, but HQL
I feel my level of English is so low. Thank you
Make sure your hibernate.cfg.xml is inside src/main/resources, if the file is not there you need to specify the right location, so put it inside this folder that your problem will be solved.
Note that we don’t have to explicitly mention the mapping or configuration or properties
files, because the Hibernate runtime looks for default filenames, such as hibernate.
cfg.xml or hibernate.properties, in the classpath and loads them. If we have a nondefault
name, make sure you pass that as an argument—like configure("my-hibcfg.
xml"), for example.

Spring-Hibernate using multiple datasource/database

I'm working on a web application that uses Spring MVC 3 and Hibernate
I want to use 2 datasource MySql and Oracle databases for my web application,
I've been read many tutorial and problem solving for "spring-hibernate multiple datasource/database"
for example :
directjump2java.blogspot.com
stackoverflow
forum spring
and etc.
but when every single time I run it, the config just read my first database config (MySql)
and show this error Table 'db_prod.ksei_lookup_holiday' doesn't exist db.prod is my first database(MySql) and KSEI_LOOKUP_HOLIDAY is my second database (Oracle),
this is my spring.xml

any help will be pleasure :)
The problem is that you have used
<property name="dataSource" ref="dataSource"></property> in sessionFactorySOAAPP.
You should have used <property name="dataSource" ref="dataSourceSOAAPP"></property>
If you check "sessionFactorySOAAPP" then the below property name should be 'dataSourceSOAAPP' not the 'dataSource'.
this my configuration file:
<bean id="dataSource"
class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="com.mysql.jdbc.Driver" />
<property name="url"

#geoand is correct in the error he spotted. Other than that the context xml seems correct and works for me.
However, for me, this only works if #qualifier is with the #Autowired.

Can the data in HSQLDB (Hyper)SQLDB be persisted to the file system

Technologies used:
Spring 3.2 (Java framework)
Hibernate 3.6 (ORM)
HSQLDB (embedded DB)
Current configuration in Spring is as follows:
<!-- Data-source -->
<jdbc:embedded-database id="dataSource" type="HSQL" />
<!-- Session Factory database -->
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="packagesToScan" value="au.com.afgonline.pce.model" />
<!-- <property name="schemaUpdate" value="true" /> -->
<property name="hibernateProperties">
<props>
<!-- <prop key="hibernate.show_sql">true</prop> -->
<prop key="hibernate.format_sql">true</prop>
<prop key="hibernate.dialect">org.hibernate.dialect.HSQLDialect</prop>
<prop key="hibernate.hbm2ddl.auto">create</prop>
</props>
</property>
</bean>
<!-- Transaction Manager -->
<bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory" />
</bean>
<!-- Hibernate Template -->
<bean id="hibernateTemplatePce" class="org.springframework.orm.hibernate3.HibernateTemplate">
<property name="sessionFactory" ref="sessionFactory"></property>
</bean>
Where do we specify the folder location for HSQLDB to save the data back to the file system?
