How to set up property in Java hibernate configuration?

I currently have hibernate bean set up in an legacy package that is using XML:
<bean name="returnsDao" class="com.mycompany.HibernateReturnsDAO">
<property name="sessionFactory" ref="myhqSessionFactory" />
</bean>
<bean id="myhqSessionFactory" name="myhqSessionFactory"
class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
<property name="dataSource">
<ref bean="myDataSource" />
</property>
<property name="hibernateProperties">
<ref bean="myHibernateProperties" />
</property>
<property name="annotatedClasses">
<list>
<value>com.mycompany.HibernateReturnsDAO</value>
</list>
</property>
</bean>
How do I create the beans in Java configuration from another package? I am trying to use the legacy package and my current package use Java config to initialize beans.
I tried the following and I am getting NPE at sessionFactory.getCurrentSession(), I suspect the Java config didn't set the property attribute properly, but how do I set up in Java config?
#Bean
public HibernateReturnsDAO returnDAO() {
return new HibernateReturnsDAO();
}

Have a look at Hibernate documentation for programmatic configuration

Broadleaf Commerce - My workflow activities are being executed twice

It seems that the built in workflow activities are being executed twice. I am testing the checkout workflow and the DecrementInventoryActivity is removing the quantity from the sku twice.
Is this a known bug or am I doing something wrong?
I created the workflow like so:
<!-- Checkout Workflow Configuration -->
<bean id="blCheckoutWorkflow" class="org.broadleafcommerce.core.workflow.SequenceProcessor">
<property name="processContextFactory">
<bean class="org.broadleafcommerce.core.checkout.service.workflow.CheckoutProcessContextFactory"/>
</property>
<property name="activities">
<list>
<bean p:order="6000" id="blDecrementInventoryActivity" class="org.broadleafcommerce.core.checkout.service.workflow.DecrementInventoryActivity">
<property name="rollbackHandler" ref="blDecrementInventoryRollbackHandler" />
</bean>
<bean p:order="7000" id="blCompleteOrderActivity" class="org.broadleafcommerce.core.checkout.service.workflow.CompleteOrderActivity">
<property name="rollbackHandler" ref="blCompleteOrderRollbackHandler" />
</bean>
<bean p:order="9999999" class="com.mycompany.workflow.checkout.NotifyExternalInventorySystem" />
</list>
</property>
<property name="defaultErrorHandler">
<bean class="org.broadleafcommerce.core.workflow.DefaultErrorHandler">
<property name="unloggedExceptionClasses">
<list>
<value>org.broadleafcommerce.core.inventory.service.InventoryUnavailableException</value>
</list>
</property>
</bean>
</property>
</bean>

Starting with Broadleaf 4.0, the DecrementInventoryActivity was added by default to the blCheckoutWorkflow. See the 3.1.10-4.0.0 migration notes at http://www.broadleafcommerce.com/docs/core/4.0/migration-notes/3.1-to-4.0-migration/3.1.10-to-4.0-migration, in the section "Inventory Management".
This also goes for the defaultErrorHandler, and you can remove the blCompleteOrderActivity (that has always been managed in the framework). Basically, your customized blCheckoutWorkflow bean should change to:
<bean id="blCheckoutWorkflow" class="org.broadleafcommerce.core.workflow.SequenceProcessor">
<property name="activities">
<list>
<bean p:order="9999999" class="com.mycompany.workflow.checkout.NotifyExternalInventorySystem" />
</list>
</property>
</bean>
Starting with Broadleaf 3.0, any modifications to the blCheckoutWorkflow bean undergo the Broadleaf XML merging processing (which merges bean ids like blCheckoutWorkflow's list of activities). In your case, since the DecrementInventoryActivity is already defined in the core framework XML file and your definition of blCheckoutWorkflow merges with it, the final result is 2 instances of the DecrementInventoryActivity.

Do I need to register all the model class in hibernate config file

Suppose I have number of model classes(Entity class). Do I need to register all the model class in hibernate config file one after another like
...
<mapping class="com.java.ent.Table"/>
...
or any annotation is there which marks as entity? For medium app there would be huge amount of table and its corresponding model entity. how to manage it?

There another way to configure hibernate sessionFactory where you can actually give only packageToScan.
<bean id="sessionFactory"
class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource"></property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</prop>
<prop key="hibernate.connection.useUnicode">true</prop><!-- added -->
<prop key="hibernate.connection.characterEncoding">UTF-8</prop><!-- added -->
<prop key="hibernate.connection.charSet">UTF-8</prop><!-- added -->
</props>
</property>
<property name="packagesToScan">
<list>
<value>com.web.entities</value>
</list>
</property>
</bean>

You can write your own set package in AnnotationConfiguration as described in the dicumentation.
https://docs.jboss.org/hibernate/stable/annotations/reference/en/html/ch01.html
Or
Another option is to write custom AnnotationConfigurationWithWildcard which extends the org.hibernate.cfg.AnnotationConfiguration and inject as spring dependency.
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="configurationClass" value="org.hibernate.cfg.AnnotationConfigurationWithWildcard"/>
<property name="configLocation" value="classpath:hibernate.cfg.xml"/>
</bean>
You can use which ever suits you better.

Override xml-defined spring bean in java-based configuration

I'm extending a complete product called Hippo CMS with my own REST interface. Hippo CMS is using Apache CXF for rest and acquires resources definitions from a spring bean defined somewhere in Hippo CMS sources. This definition look like this:
<bean id="jaxrsRestPlainResourceProviders" class="org.springframework.beans.factory.config.MethodInvokingFactoryBean">
<property name="targetClass" value="org.apache.commons.collections.ListUtils" />
<property name="targetMethod" value="union" />
<property name="arguments">
<list>
<ref bean="customRestPlainResourceProviders" />
<ref bean="defaultRestPlainResourceProviders" />
</list>
</property>
</bean>
<bean id="defaultRestPlainResourceProviders" class="org.springframework.beans.factory.config.ListFactoryBean">
<property name="sourceList">
<list>
</list>
</property>
</bean>
<!-- Default empty list of custom plain resource providers to be overriden. -->
<bean id="customRestPlainResourceProviders" class="org.springframework.beans.factory.config.ListFactoryBean">
<property name="sourceList">
<list>
</list>
</property>
</bean>
I need to override customRestPlainResourceProviders bean with my own bean. It works fine from XML configuration looking like this:
<bean id="customRestPlainResourceProviders" class="org.springframework.beans.factory.config.ListFactoryBean">
<property name="sourceList">
<list>
<bean class="org.apache.cxf.jaxrs.lifecycle.SingletonResourceProvider">
<constructor-arg>
<bean class="com.xxx.rest.FolderStructureResource"/>
</constructor-arg>
</bean>
</list>
</property>
</bean>
But it doesn't work if I define a bean in Java configuration class (which in the case of other beans works completely fine):
#Bean(name = "customRestPlainResourceProviders")
public ListFactoryBean customRestPlainResourceProviders() {
ListFactoryBean listFactoryBean = new ListFactoryBean();
listFactoryBean.setSourceList(
Lists.newArrayList(
new SingletonResourceProvider(
new FolderStructureResource(repository())
)
)
);
return listFactoryBean;
}
Is there a way to override a bean defined in XML configuration with a bean created in Java configuration class?

What version of spring are you using? I believe this issues is addressed in 4.2.

Spring and hibernate.cfg.xml

How do I get Spring to load Hibernate's properties from hibernate.cfg.xml?
We're using Spring and JPA (with Hibernate as the implementation). Spring's applicationContext.xml specifies the JPA dialect and Hibernate properties:
<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalEntityManagerFactoryBean">
<property name="jpaDialect">
<bean class="org.springframework.orm.jpa.vendor.HibernateJpaDialect" />
</property>
<property name="jpaProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.MySQLInnoDBDialect</prop>
</props>
</property>
</bean>
In this configuration, Spring is reading all the Hibernate properties via applicationContext.xml . When I create a hibernate.cfg.xml (located at the root of my classpath, the same level as META-INF), Hibernate doesn't read it at all (it's completely ignored).
What I'm trying to do is configure Hibernate second level cache by inserting the cache properties in hibernate.cfg.xml:
<cache
usage="transactional|read-write|nonstrict-read-write|read-only"
region="RegionName"
include="all|non-lazy"
/>

Try something like this...
<bean
id="mySessionFactory"
class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="configLocation">
<value>
classpath:location_of_config_file/hibernate.cfg.xml
</value>
</property>
<property name="hibernateProperties">
<props>
...
</props>
</property>
</bean>

The way I've done this before is by instantiating a LocalSessionFactoryBean and setting the configLocation property.
