Also I want to mention that this is a dynamic web application where I have put the hibernate.cfg.xml file in the WEB-INF/classes folder within the WebContent folder. This is A Spring MVC and hibernate project. Thank You
I've solved the problem with the application. I have used Spring MVC and hibernate in my web application. As I'm trying to integrate Spring with Hibernate, I used the LocalSessionFactoryBean in my applicationContext.xml instead of using hibernate.cfg.xml file. This solved the issue.
Here is the applicationContext.xml file :
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx.xsd">
<mvc:annotation-driven/>
<context:component-scan base-package="com.gavs" />
<!-- Resolves views selected for rendering by @Controllers to .jsp resources
in the /WEB-INF/views directory -->
<bean
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/views/" />
<property name="suffix" value=".jsp" />
</bean>
<!-- Step 1: Define Database DataSource / connection pool -->
<bean id="myDataSource" class="org.apache.commons.dbcp2.BasicDataSource" destroy-method="close">
<property name="driverClassName" value="com.mysql.jdbc.Driver"/>
<property name="url" value="jdbc:mysql://localhost:3306/initdb"/>
<property name="username" value="root"/>
<property name="password" value="root"/>
</bean>
<!-- Step 2: Setup Hibernate session factory -->
<bean id="sessionFactory"
class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
<property name="dataSource" ref="myDataSource" />
<property name="packagesToScan" value="com.gavs.beans" />
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.MySQL8Dialect</prop>
<prop key="hibernate.show_sql">true</prop>
</props>
</property>
</bean>
<!-- Step 3: Setup Hibernate transaction manager -->
<bean id="myTransactionManager"
class="org.springframework.orm.hibernate5.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory"/>
</bean>
<!-- Step 4: Enable configuration of transactional behavior based on annotations -->
<tx:annotation-driven transaction-manager="myTransactionManager" />
<bean id="stud" class="com.gavs.dao.StudentDaoImpl">
</bean>
</beans>
By adding these beans to applicationContext.xml, the SessionFactory can be injected in the required class and used. So there is no need of hibernate.cfg.xml file.
