I was just wondering what is the best way to use hibernate & spring in our Application, like i have implemented hibernate in my web application. Every thing is working fine but the thing is i have a list of classes which i have in my applicationcontext.xml class Now when i need to use any of those classes I make object of this applicationContext.xml class as below

ApplicationContext ctx = new ClassPathXmlApplicationContext(
"applicationContext.xml");
MySQLRdbSpringHelper rdbHelper = (MySQLRdbSpringHelper) ctx.getBean("ManagerJobs");
but by this method ,the program invokes all of the classes in application context.xml(below) in the List which uses more memory, isn't there a way to invoke the only class which we need one at a time..?

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="annotatedClasses">
<list>
<value>com.zrsol.joblistings.shared.Employer</value>
<value>com.zrsol.joblistings.shared.StatesProvinces</value>
<value>com.zrsol.joblistings.shared.EmployerJobs</value>
<value>com.zrsol.joblistings.shared.CandidateResumeInfo</value>
<value>com.zrsol.joblistings.shared.CandidateSkills</value>
<value>com.zrsol.joblistings.shared.CandidateInfo</value>
<value>com.zrsol.joblistings.shared.SelectedResumes</value>
<value>com.zrsol.joblistings.shared.SecretQuestionsBean</value>
<value>com.zrsol.joblistings.shared.Categories</value>
<value>com.zrsol.joblistings.shared.EducationLevel</value>
<value>com.zrsol.joblistings.shared.Salary</value>
<value>com.zrsol.joblistings.shared.JobLevel</value>
<value>com.zrsol.joblistings.shared.EmployerCvSearches</value>
</list>
</property>
</bean>
<bean id ="ManagerJobs" class= "jobsite.persistence.MySQLRdbSpringHelper">
<property name="sessionFactory" ref="sessionFactory" />
</bean>



Thanks

No all the classes will be initialized but I don't see wher you would get a memory problem from this, it's not like hibernate will load the whole DB into memory
