Abstract routing datasource with different Databases - java

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:
i have defined 3 datasources itemDataSource, custDataSource, orderDb2DataSource in dao.xml .
how to configure the second session factory to the the transaction manager ?
<bean id="dataSource" class="com.test.DatabaseRoutingDataSource">
<property name="targetDataSources">
<map key-type="com.test.dao.DatabaseType">
<entry key="ITEM" value-ref="itemDataSource"/>
<entry key="CUSTOMER" value-ref="custDataSource"/>
<entry key="ORDER_DB2" value-ref="orderDb2DataSource"/>
</map>
</property>
<property name="defaultTargetDataSource" ref="itemDataSource" />
</bean>
<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
<property name="dataSource">
<ref bean="dataSource" />
</property>
<property name="configLocation">
<value>/WEB-INF/hibernate.cfg.xml</value>
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.MySqlDialect</prop>
<prop key="hibernate.show_sql">true</prop>
</props>
</property>
</bean>
<!-- Added for DB2 Database -->
<bean id="sessionFactoryDB2" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
<property name="dataSource">
<ref bean="dataSource" />
</property>
<property name="configLocation">
<value>/WEB-INF/hibernate.db2.cfg.xml</value>
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.DB2Dialect</prop>
<prop key="hibernate.show_sql">true</prop>
</props>
</property>
</bean>
<!-- Added for DB2 Database -->
<bean id="transactionManager1"
class="org.springframework.orm.hibernate4.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory"/>
</bean>

Exit program on Spring jpa/Hibernate connection exception

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="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName">
<value>${db.driver}</value>
</property>
<property name="url">
<value>${db.url}</value>
</property>
<property name="username">
<value>${db.username}</value>
</property>
<property name="password">
<value>${db.password}</value>
</property>
</bean>
<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" />
</property>
<property name="packagesToScan" value="com.template" />
<property name="jpaProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.format_sql">false</prop>
<prop key="hibernate.hbm2ddl.auto">update</prop>
<prop key="hibernate.ejb.naming_strategy">${naming_strategy}</prop>
<prop key="hibernate.connection.autoReconnect">true</prop>
<prop key="hibernate.connection.autoReconnectForPools">true</prop>
<prop key="hibernate.connection.check-valid-connection-sql">SELECT 1</prop>
<prop key="hibernate.connection.failOverReadOnly">false</prop>
<prop key="hibernate.connection.maxReconnects">${maxreconnects}</prop>
<prop key="hibernate.connection.initialTimeout">${reconnect.interval}</prop>
</props>
</property>
</bean>
<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 ?

Quartz Cron scheduler in Spring with jdbc store

I need to create Cron service in Spring, but I can not find enough info how to do it with jdbc store. I want Quartz to use my present connection to Datasource, my database is PostgreSql. I need to create use jdbc store, because task should be done even if server was down.
You can try something like this
<bean id="scheduler-JDBC" class="org.springframework.scheduling.quartz.SchedulerFactoryBean" abstract="true">
<property name="dataSource" ref="myDataSource" />
<property name="transactionManager" ref="transactionManager" />
<property name="jobFactory">
<bean class="org.springframework.scheduling.quartz.SpringBeanJobFactory" />
</property>
<property name="overwriteExistingJobs" value="true" />
<property name="quartzProperties">
<props>
<prop key="org.quartz.jobStore.isClustered">false</prop>
<prop key="org.quartz.jobStore.driverDelegateClass">org.quartz.impl.jdbcjobstore.StdJDBCDelegate</prop>
<prop key="org.quartz.scheduler.instanceId">AUTO</prop>
<prop key="org.quartz.scheduler.skipUpdateCheck">true</prop>
</props>
</property>
</bean>
<bean id="cronScheduler" class="org.springframework.scheduling.quartz.SchedulerFactoryBean" parent="scheduler-JDBC">
<property name="startupDelay" value="10" />
<property name="autoStartup" value="true" />
<property name="applicationContextSchedulerContextKey" value="applicationContext"/>
<property name="triggers">
<list>
<ref bean="myTrigger" />
</list>
</property>
</bean>
Download Quartz distribution from http://quartz-scheduler.org/ and you will find the database script for needed tables in docs/dbTables.

Unable to start hibernate session factory bean

Here is my hibernate config
<bean id="datasource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
<property name="driverClassName" value="org.h2.Driver"/>
<property name="url" value="jdbc:h2:mem:/localhost/testDB"/>
<property name="username" value="sa"/>
<property name="password" value=""/>
</bean>
<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
<property name="dataSource" ref="datasource" />
<property name="packagesToScan" value="sample.model"/>
<property name="annotatedPackages">

<value>sample.model</value>
</list>
</property>
<property name="hibernateProperties">

<prop key="hibernate.dialect"> org.hibernate.dialect.H2Dialect</prop>
<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)
at org.springframework.util.ClassUtils.getMethod(ClassUtils.java:627)
at org.springframework.orm.hibernate4.LocalSessionFactoryBuilder.<clinit>(LocalSessionFactoryBuilder.java:79)
... 39 more
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>
</property>
</bean>

Configuring Hibernate XML with P-Namespace

I want to rewrite my sessionFactory bean using the p-namespace. I understand how to reference general objects, but I've never dealt with lists, props, etc. How would I go about writing , and so on?
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource"/>
<property name="mappingResources">
<list>
<value>/com/mysite/domain/Object.hbm.xml</value>
</list>
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.HSQLDialect</prop>
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.hbm2ddl.auto">update</prop>
</props>
</property>
</bean>
This is the code I have so far in p-namespace:
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"
p:dataSource-ref="dataSource"
p:mappingResources-list="/com/mysite/domain/Object.hbm.xml"
p:hibernateProperties-props=""/>
You cannot do this directly . You could use util:map though. Try
<util:map id="hibernateConfig" >
<entry key="hibernate.hbm2ddl.auto" value="update" />
<entry key="hibernate.show_sql" value="true" />
<!-- Other properties -->
</util:map>
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"
p:dataSource-ref="dataSource"
p:mappingResources-list="/com/mysite/domain/Object.hbm.xml"
p:hibernateProperties-ref ="hibernateConfig"/>
Check This for complete help on p:namespace

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.
