I want my program to exit if it cannot connect to the database on startup. Currently this connection is setup using the following:
application-context.xml

<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
<property name="entityManagerFactory" ref="entityManagerFactory" />
</bean>
Repository:
#Repository
public interface Repository extends CrudRepository<Object, String> {
}
It's not obvious where I should place code to catch the runtime exceptions created by the connection failure. Are there any other settings I can use to exit if the database doesn't exist.
Usually, spring will stop, if it could not create a bean at startup. If DB connection fails, then it will stop automatically anyway. Do you want to catch that exception, and do something before exit ?

We have an application where we have implemented Abstract Routing Data source feature in dealing multiple data bases of same type mysql (jdbc:mysql://127.0.0.1:3306/test, jdbc:mysql://127.0.0.1:3306/test2).
Now we are going with different database which is DB2. so i was unable to find any samples for this scenario using abstract routing datasource.
Can anyone give any directions ?
This is my code block:

Then each dao gets a different sessionFactory assigned
<bean id="productDao"
class="test.dao.ProductDaoHibernate">
<property name="sessionFactory"><ref bean="sessionFactory" /></property>
</bean>
<bean id="currencyDao"
class="test.dao.CurrencyDaoHibernate">
<property name="sessionFactory"><ref bean="sessionFactory2" /></property>
</bean>
This config gets loaded when its added to the context
web.xml:
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/classes/test-data.xml /WEB-INF/classes/test-services.xml ... </param-value>
</context-param>
The problem shows whenever I start the server each sessionFactory built, but at the end of the second one this shows up:
[INFO] [org.springframework.beans.factory.support.DefaultListableBeanFactory]:? - Destroying singletons in org.springframework.beans.factory.support.DefaultListableBeanFactory#97aaa6: defining beans [... Many elements...]; root of factory hierarchy

Actually this is supposed to be a comment, but don't have enough reputation (requires 50 points)
It seems you are trying to create 2 different bean id's which are of exactly same configuration. One way is to figure out whether 2 different session objects pointing to same configuration is required. Other way is to try adding the configurations in different files and load separately. Please add how you r trying to use these configurations in code.
I have a web application created with Spring data, which uses JpaRepository (org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean with org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter) after some server uptime I have noticed that heap is growing all the time.
After taking a heap dump it shows that heap contains much more entities than I am currently using.
So my question is how to manage EntityManager to clear entities that are not being used any more?
Here is jpa configuration:
<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="dataSource" ref="dataSource"/>
<property name="jpaVendorAdapter">
<bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter" p:database="${jdbc.databaseType}"
p:generateDdl="true" p:showSql="false"/>
</property>

<prop key="hibernate.connection.useUnicode">true</prop>

Here is my hibernate config

<property name="username" value="sa"/>
<property name="password" value=""/>

<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.hbm2ddl.auto">create</prop>
</props>
</property>
</bean>
I included this dependency
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-annotations</artifactId>
<version>3.5.6-Final</version>
</dependency>
Here is the exception
Caused by: java.lang.IllegalStateException: Expected method not found: java.lang.NoSuchMethodException: org.hibernate.cfg.Configuration.addAnnotatedClass(java.lang.Class)

What am I missing here?
It looks like your hibernate annotations jar file is the incorrect version.
You should already have hibernate-core as a dependency. If so you can comment out your hibernate-annotations dependency in your POM file.
The solution was to use hibernate 3 and Adding this
<prop key="hibernate.current_session_context_class">org.hibernate.context.ThreadLocalSessionContext</prop>
So the final config is
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
<property name="dataSource" ref="datasource" />
<property name="packagesToScan" value="sample.model"/>
<property name="annotatedPackages">
<list>
<value>sample.model</value>
</list>
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect"> org.hibernate.dialect.H2Dialect</prop>
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.hbm2ddl.auto">create</prop>
<prop key="hibernate.current_session_context_class">org.hibernate.context.ThreadLocalSessionContext</prop>
</props>

What should i do? Thanks in advance.
Use inner classes. No serialization is required.
http://shyarmal.blogspot.com/2011/07/quartz-20-schedule-cron-with-spring.html
EmailSenderJob and all of its members need to implement Serializable.
