Jotm framework with Hibernate integrated technology sharing
Jotm framework with Hibernate integrated technology sharing
In modern Java application development, transaction management is a very important part of.The JOTM framework and Hibernate are two very common Java technology, which are responsible for transaction management and database access.This article will introduce how to integrate the JOTM framework and Hibernate to achieve transaction management and data persistence in Java applications.
1. Jotm framework profile
JOTM (Java Open Transaction Manager) is an open source Java affairs management framework.It provides a scalable and easy -to -use way to manage transactions, and is compatible with a variety of affairs management protocols, such as JTA (Java Transaction API), JDBC (Java DataBase Connectivity) and JMS (Java Message Services).Using the JOTM framework can simplify the realization of transaction management and provide high availability and reliability.
Introduction to Hibernate
Hibernate is a widely used Java object relationship mapping (ORM) framework.It provides a solution that persists in the Java object to the database, which simplifies the development of data access layers.Hibernate is mapping between the Java object and the database table through object relationship mapping technology, so that developers can use object -oriented methods for database operations.
3. JOTM framework and Hibernate integrated
1. Add Maven dependence
First of all, you need to add JOTM and Hibernate dependencies to Maven.
<dependency>
<groupId>org.objectweb.jotm</groupId>
<artifactId>jotm</artifactId>
<version>2.1.11</version>
</dependency>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-core</artifactId>
<version>5.4.30.Final</version>
</dependency>
2. Create Hibernate configuration file
Create a Hibernate configuration file, such as hibernate.cfg.xml.In this configuration file, configure database connection information and mapping file paths.
<hibernate-configuration>
<session-factory>
<property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="hibernate.connection.url">jdbc:mysql://localhost/mydatabase</property>
<property name="hibernate.connection.username">root</property>
<property name="hibernate.connection.password">password</property>
<!-Other configuration items->
<mapping resource="com/example/Entity.hbm.xml" />
</session-factory>
</hibernate-configuration>
3. Create a JOTM transaction factory
When using the JOTM framework, a JOTM transaction factory needs to be created.
import org.objectweb.jotm.Jotm;
import org.objectweb.jotm.TransactionManager;
public class JotmTransactionFactory {
private static TransactionManager transactionManager;
public static TransactionManager getTransactionManager() {
if (transactionManager == null) {
Jotm jotm = new Jotm(true, false);
transactionManager = jotm.getTransactionManager();
}
return transactionManager;
}
}
4. Create Hibernate session factory
Next, you need to create a Hibernate session factory.When creating a professional factory, integrate the JOTM work factory with Hibernate.
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
import org.hibernate.engine.transaction.jta.platform.internal.JOTMJtaPlatform;
public class HibernateSessionFactory {
private static SessionFactory sessionFactory;
public static SessionFactory getSessionFactory() {
if (sessionFactory == null) {
Configuration configuration = new Configuration();
configuration.configure("hibernate.cfg.xml");
configuration.setProperty("hibernate.transaction.jta.platform", JOTMJtaPlatform.class.getName());
ServiceRegistry serviceRegistry = new StandardServiceRegistryBuilder()
.applySettings(configuration.getProperties()).build();
sessionFactory = configuration.buildSessionFactory(serviceRegistry);
}
return sessionFactory;
}
}
5. Use Hibernate for transaction management and data access
Now you can use Hibernate for transaction management and data access.Below is a simple example, demonstrating how to use Hibernate to save a physical object.
import org.hibernate.Session;
import org.hibernate.Transaction;
public class PersistenceExample {
public static void main(String[] args) {
TransactionManager tm = JotmTransactionFactory.getTransactionManager();
SessionFactory sessionFactory = HibernateSessionFactory.getSessionFactory();
try {
tm.begin();
Session session = sessionFactory.getCurrentSession();
Entity entity = new Entity();
// Set the attribute of the physical object
session.save(entity);
tm.commit();
} catch (Exception e) {
tm.rollback();
e.printStackTrace();
}
}
}
Through the above steps, you have successfully integrated the JOTM framework and Hibernate, and realized the function of transaction management and data persistence.
Summarize
This article introduces the technical sharing of JOTM framework with Hibernate integrated.By integrating the JOTM framework and Hibernate, simplified transaction management and data persistence can be achieved.Using the example code, you can start trying to apply the JOTM framework and Hibernate in the Java application.I hope this article will help you, thank you for reading!
