According to the documentation http://docs.spring.io/spring-framework/docs/3.2.2.RELEASE/spring-framework-reference/html/beans.html#beans-factory-lazy-init the below should not be instatiating MyDatabase yet I can clearly see this is the case in the afterPropertiesSet method of the HibernateDatabase class when debugging. If I remove MyDatabaseEntityManagerFactory then this does not occur. However this should not matter given that MyDatabaseEntityManagerFactory is also lazy - it should not cause MyDatabase to initialise.
Either I'm misunderstanding the part of the docs that say that a lazy bean referencing another lazy bean shouldn't cause it to initialise or there is a fundamental problem in Spring here. Can anyone shed some light on this or possibly suggest an alternative to what I want to achieve?
Thanks.

Use Case: I am running a spring application which has orders. I can create plans for these orders. My dev environment/db does not have any orders and they come from a different application (we share the same db). So, Is there a way I can read orders from production database but when I create a plan, it gets saved to dev database?

In my Jetty server config, I am defining the srvPropertyFile which references to the environment.properties file which has the database connection to dev db.
How should I manage my persistence context so that the entity manager used while reading orders and the entity manager used while creating plans connects to different databases?
you have to configure two persistence unit, data source and transaction manager(one for read and other for write) each.
While using entity manager specify the persistence unit like below.
PersistenceUnit(unitName = "x")
EntityManagerFactory entityManagerFactory;
I have been trying for more than an hour to display an image in my SpringBoot version 1.5.3 application.
I'm trying to display an image in my html page, which is the path:
And have used the image as:
<img src="images/DataServicesAdminAppLogo.png" width="40" height="40" class="d-inline-block align-top" alt="" hspace="10"/>
in my html page. But in vain. The image is not getting displayed.
Can someone please help?

I have an application setup based on a previous configuration - which was 100% functional. Now I am using maven and am encountering an Error in my controller class which says i must configure Beans.xml.
I'm not sure exactly what this means, as I have my dispatcher-servlet.xml configured in the same way as the functional application.

I am using hibernate 4 spring 3 maven 3, i have this configuratiobn file and here I am using local session factory and it compile correctly but it gives the error
when I am using the JBoss server to deploy it then server console gives the error 'configurationClass' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter? please help me to sort out this problem
Your bean definition suggests that you are trying to configure Hibernate 3, not Hibernate 4. You have probably followed incorrect example or tutorial. In Hibernate 4 there is no configurationClass property. Just remove it:
<bean id="usermanagementSessionFactory"
class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
<property name="dataSource" ref="usermanagementDataSource" />
<property name="configLocation" value="classpath:hibernate.cfg.xml" />
<property name="hibernateProperties" ref="hibernateProperties" />
</bean>
With Hibernate 4, you also don't need to provide configuration XML. All you can do is to specify packages to be scanned for #Entity classes:
<property name="packagesToScan" value="com.ecom.data.access.model" />
I'm setting up a maven-spring-hibernate-mysql-tomcat environment.
I would like to inject my Entity manager using the #PersistenceContext annotation.
As I understand to do this, I should have PersistenceAnnotationBeanPostProcessor defined in my application context, pointing to my persistence.xml file.
In this case my application context could be looking like this more or less:

My persistence.xml could look like this:
<persistence-unit name="myPU" transaction-type="RESOURCE_LOCAL">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<properties>
<property name="hibernate.transaction.flush_before_completion"
value="true" />
<property name="hibernate.dialect" value="org.hibernate.dialect.MySQLInnoDBDialect" />
<property name="hibernate.show_sql" value="true" />
</properties>
</persistence-unit>
So now I guess I should be able to inject my entity manager using the #PersistenceContext annotation, at list this is what I get from the documentation. Before I'mm getting to JpaVendorAdapter, my first question would refer the entity manager factory definition:
The following properties:
<property name="persistenceXmlLocation" value="classpath:META-INF/persistence.xml"/>
<property name="persistenceUnitName" value="myPU" />
Are these required to be referred from the entity manager factory? Is it a must?
My second question would be regarding the JpaVendorAdapter, and in my case HibernateJpaVendorAdapter.
If I use HibernateJpaVendorAdapter, do I still need to have a persistence.xml file? Since some of the properties are overlapping. Moreover, do I still need to have PersistenceAnnotationBeanPostProcessor defined, pointing to my persistence.xml file? Can these 2 go together (PersistenceAnnotationBeanPostProcessor and HibernateJpaVendorAdapter)? Should they go together? What is the best practice, assuming I'm avoiding any JDNI style definitions?
Thanks in advance
The combination of data source bean and HibernateJpaVendorAdapter allows you to get rid of persistence.xml with Spring 3.1. Check out this article:
http://www.baeldung.com/2011/12/13/the-persistence-layer-with-spring-3-1-and-jpa/
So the answers:
They are not a must.
No, you don't need to have a persistence.xml.
I am not exactly sure of what use PersistenceAnnotationBeanPostProcessor is.
<context:component-scan base-package="com.demo.dao" />
<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalEntityManagerFactoryBean">
<property name="persistenceUnitName" value="hibernate-resourceLocal"/>
</bean>
<tx:annotation-driven/>
<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
<property name="entityManagerFactory" ref="entityManagerFactory" />
</bean>
My Spring application context xml looks as simple as this. And it is working.
I don't what the best practice is, but I will keep persistence.xml so that in case I need to expose my service as session bean, it can be easily done.
