I am fairly new to spring batch. I have it working embedded inside my spring mvc web application. It is using a db2 database data store to log job information. At present my batch-db2.properties reads as...
batch.jdbc.driver=com.ibm.db2.jcc.DB2Driver
batch.jdbc.url=<<my database url>>
batch.jdbc.user=<<my database user>>
batch.jdbc.password=<<my database password>>
batch.schema=<<my database scehma>>
batch.jndi.name=jdbc/<<my jndi url>>
So I've set both jdbc properties and well as the jndi property. The jobs are running fine but my question is what type of connection is my spring batch installation using.
If both are set does it use jdbc or jndi? Also can someone point me to the spring batch documentation page where it gives more information about these settings. I could not find it.
Here is my data source configuration....
<beans profile="server">
<bean id="ePosDataSource"
class="org.springframework.jndi.JndiObjectFactoryBean"
p:jndiName="java:comp/env/jdbc/reportingManagerDataSource"
p:lookupOnStartup="false"
p:cache="true"
p:proxyInterface="javax.sql.DataSource"/>
<jee:jndi-lookup id="ePosDataSource"
jndi-name="jdbc/reportingManagerDataSource"
cache="true"
resource-ref="true"
lookup-on-startup="false"
proxy-interface="javax.sql.DataSource"/>
<bean id="custDbDataSource"
class="org.springframework.jndi.JndiObjectFactoryBean"
p:jndiName="java:comp/env/jdbc/reportingManagerCustDbDataSource"
p:lookupOnStartup="false"
p:cache="true"
p:proxyInterface="javax.sql.DataSource" />
<jee:jndi-lookup id="custDbDataSource"
jndi-name="jdbc/reportingManagerCustDbDataSource"
cache="true"
resource-ref="true"
lookup-on-startup="false"
proxy-interface="javax.sql.DataSource"/>
</beans>
thanks!

Running ActiveMQ in clustered environment with a Master/Slave relationship using Oracle as a datastore. Using a jdbcPersistentAdapter.

The activemq broker is running embedded in JBoss.
I would like to replace the dataSource bean (contains credentials and url string) with a JNDI reference since that already manages the database connection. Is this possible?
Load the dataSourcebean from JNDI instead. Something like this should work (using a correct JNDI name from your setup).
<bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiName" value="java:comp/env/jdbc/MyDatabase"/>
</bean>
I have developed a small webapp using and SpringMVC(3.1.3.RELEASE) and Hibernate 4.2.0.Final.
I'm trying to convert it to be a multi-tenant application.
Similar topics have been covered in other threads, but I couldn't find a definitive solution to my problem.
What I am trying to achieve is to design a web app which is able to:
Read a datasource configuration at startup (an XML file containing multiple datasource definitions, which is placed outside the WAR file and it's not the application-context or hibernate configuration file)
Create a session factory for each one of them (considering that each datasource is a database with a different schema).
How can i set my session factory scope as session? ( OR Can i reuse the same session factory ?) .
Example:
Url for client a - URL: http://project.com/a/login.html
Url for client b - URL: http://project.com/b/login.html
If client "a" make request,read the datasource configuration file and Create a session factory using that XML file for the client "a".
This same process will be repeating if the client "b" will send a request.
What I am looking, how to implement datasource creation upon customer subscription without editing the Spring configuration file. It needs to be automated.
Here is my code ,that i have done so far.
Please anyone tell me,What modifications i need to be made?
Please give an answer with some example code..I am quite new in spring and hibernate world.
Spring.xml
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
destroy-method="close" p:driverClassName="${jdbc.driverClassName}"
p:url="${jdbc.databaseurl}"
p:username="${jdbc.username}" p:password="${jdbc.password}" />
<bean id="sessionFactory"
class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="configLocation">
<value>classpath:hibernate.cfg.xml</value>
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">${jdbc.dialect}</prop>
<prop key="hibernate.show_sql">true</prop>
</props>
</property>
</bean>
<bean id="transactionManager"
class="org.springframework.orm.hibernate4.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory" />
JDBC.properties File
jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.dialect=org.hibernate.dialect.MySQLDialect
jdbc.databaseurl=jdbc:mysql://localhost:3306/Logistics
jdbc.username=root
jdbc.password=rot#pspl#12

Thanks,
First create a table for Tenant with tenant_id and associate it with all users.Now, you can fetch this details while the user logs in and set it in session.
We are using AbstractRoutingDataSource to switch DataSource for every request on Spring Boot. I think it is Hot Swapable targets/datasource mentioned by #bhantol above.
It solves our problems but I don't think it is sound solution. I guess JNDI could be a better one than AbstractRoutingDataSource.
Wondering what you ended up with.
Here are some ideas for you.
Option 1) Single Application Instance.
It is somewhat ambitious to to this using what you are actually trying to achieve.
The gist is to simply deploy the same exact application with different context root on the same JVM. You can still tune the JVM as a whole like you would have if you had a truely multi-tenant application. But this comes at the expense of duplication of classes, contexts, local caching, start up times etc.
But as of today the Spring Framework 4.0 does not provide much of an multi-tenancy support (other than Hot Swapable targets/datasource) etc. I am looking for a good framework but it may be a wash to move away from Spring at this time for me.
Option 2) Multiple deployments of same application (more practical as of today)
Just have your same exact application deploy to the same application server JVM instance or even different.
If you use the same instance you may now need to bootstrap your app to pickup a DataSource based on what the instance should serve e.g. client=a property would be enough to pickup a **a**DataSource" or **b**DataSource I myself ended up going this approach.
If you have a different application server instance you could just configure a different JNDI path and treat things generically. No need for client="a" property because you have liberty to define your datasource differently with the same name.
I am first time making a webapp for Jboss server.
For JBoss we have the jndi details, but I am wondering how to create the Datasource using it in spring application context.
If anyone has an example to create the connection, please share it.
I will put this sample here.
just to show another way to do it.
<bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiName">
<value>java:jboss/datasources/DSName</value>
</property>
</bean>
I found the solution
Add below configuration to applicationContext.xml
xmlns:jee="http://www.springframework.org/schema/jee"
xsi:schemaLocation="http://www.springframework.org/schema/jee
http://www.springframework.org/schema/jee/spring-jee-3.0.xsd"
<jee:jndi-lookup expected-type="javax.sql.DataSource" id="dataSource" jndi-name="java:jboss/SAMPLE_JNDI"/>
I want to read Tomcat datasource via JNDI in my Spring configuration i am using oracle toplink
in spring applicationContext.xml i am using like below
<bean id="UserDatabase" class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiName" value="java:comp/env/jdbc/ISM_rep_user"></property>
<property name="lookupOn" value="true"></property></bean>
and in tomcat/conf/context.xml i am using below
Thanks,
Maybe the lookupOn property has no vaid XML syntax (missing ")?
I'm developing a Spring MVC application using ibatis for the database interaction layer. I'd like to be able to set the name of the database via a properties file in my classpath (or via the spring xml configuration) so I can change the database on the fly for a certain application and can be changed by setting the parameter and redeploying the application.
What I'm looking for is being able to set the database name on an existing database. Lets say I have a system called DB1 with databases: user, user_qa, and user_dev. I'd like to be able to parameterize the SQLs so that instead of doing:
SELECT * FROM user.Logins
I'd do
SELECT * FROM $database.user$.Logins
So I can change the database.user property and redeploy the application instead of rewriting a ton of SQL statements each time I changed the name of the databases.
Pretty simple to do in Spring. Say you have a basic conf file [database.properties]:
jdbc.username = user
jdbc.host = mydbserver.com
Then in your Spring config xml file :
<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="location">
<value>classpath:database.properties</value>
</property>
</bean>
Now where you want those variables substitute the name in the config file:
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="host"><value>${jdbc.host}</value></property>
<property name="username"><value>${jdbc.username}</value></property>
</bean>
