I want to use Spring Data JPA with Hibernate mapping files and without JPA-Annotations.
But I'am facing this exception on server startup (tomcat):
java.lang.IllegalStateException: No persistence units parsed from {classpath*:META-INF/persistence.xml}
at org.springframework.orm.jpa.persistenceunit.DefaultPersistenceUnitManager.obtainDefaultPersistenceUnitInfo(DefaultPersistenceUnitManager.java:547)
at org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean.determinePersistenceUnitInfo(LocalContainerEntityManagerFactoryBean.java:311)
at org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean.createNativeEntityManagerFactory(LocalContainerEntityManagerFactoryBean.java:260)
My dispatch-servlet.xml looks like the following:
<bean id="entityManagerFactory"
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<!--<property name="persistenceUnitName" value="BLUPP" />-->
<property name="dataSource" ref="dataSource" />
<property name="jpaVendorAdapter" ref="hibernateJpaVendorAdapter" />
<!-- <property name="packagesToScan" value="org.cleanyourway.server.beans" />-->
<property name="persistenceUnitPostProcessors">
<list>
<bean
class="org.springframework.data.jpa.support.ClasspathScanningPersistenceUnitPostProcessor">
<constructor-arg value="org.xxxxxx.server.beans" />
<property name="mappingFileNamePattern" value="**hbm.xml" />
</bean>
</list>
</property>
</bean>
Is it possible to use Hibernate mapping files with the ClasspathScanningPersistenceUnitPostProcessor?
I get it running with
<property name="packagesToScan" value="org.xxxxxxx.server.beans" />
and JPA Annotations.
Thanks for your help!
Briefly
Your problem probably comes from the mappingFileNamePattern you provide. Try **/*.hbm.xml instead of **hbm.xml.
Complete snippet:
<bean id="entityManagerFactory"
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<!--<property name="persistenceUnitName" value="BLUPP" />-->
<property name="dataSource" ref="dataSource" />
<property name="jpaVendorAdapter" ref="hibernateJpaVendorAdapter" />
<!-- <property name="packagesToScan" value="org.cleanyourway.server.beans" />-->
<property name="persistenceUnitPostProcessors">
<list>
<bean
class="org.springframework.data.jpa.support.ClasspathScanningPersistenceUnitPostProcessor">
<constructor-arg name="basePackage" value="org.xxxxxx.server.beans" />
<property name="mappingFileNamePattern" value="**/*hbm.xml" />
</bean>
</list>
</property>
</bean>
In details
Ant path patterns
Spring uses Ant path style patterns. You can find a good documentation on those patterns on the Ant Website. Double asterisk wildcard means: recurse in subdirectories. It should be followed by a slash as it stands for a directory.
ClasspathScanningPersistenceUnitPostProcessor
The mapping file detection part of ClasspathScanningPersistenceUnitPostProcessor takes the two parameters (basePackage (your constructors args) and mappingFileNamePattern) into account. With the suggested correction, Spring will search all **.hbm.xml* in subfolders org/xxxxxx/server/beans/ of the classpath.
Rephrased, you cannot expect that your mappingFileNamePattern would be interpreted alone for the search.
Hereunder, the code snippet of ClasspathScanningPersistenceUnitPostProcessor that makes the job:
String path = ResourcePatternResolver.CLASSPATH_ALL_URL_PREFIX
+ basePackage.replace('.', File.separatorChar)
+ File.separator + mappingFileNamePattern;
Small limitation of ClasspathScanningPersistenceUnitPostProcessor
You cannot scan for HBM files located at the root of JAR files in your classpath. basePackage doesn't support being empty and doesn't work with just a "." value.
Moreover, the underlying PathMatchingResourcePatternResolver doesn't work with Ant style path pattern with wilcard (* in you case) without a root directory (here and here (first warning in Other notes)).
Bug of ClasspathScanningPersistenceUnitPostProcessor
This class has never worked with Hibernate.
In the pre-1.4.x releases, there was this bug.
With this pull request, it seems there is a new bug that prevents me from getting the whole thing working with HBM in JARs. I got a NullPointerException at the line 146 because resource.getURI().getPath(); doesn't seem to work with an URI with two : in the protocol (jar:file:/ in this case) and returns a null path.
(I will update my answer with a link to a bug report either when I have find one or posted one.)

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.
I asked a similar question, but based on the responses, I did a bad job describing what I am after. I have a spring 4 webapp that loads properties from a properties file. We consume those properties both via the "${proper.name"} expressions in spring, as well as by injecting a properties object into some of our classes.
We want to move most of the properties to a database table and make them reloadable. However, a few need to stay in local properties, potentially overriding the database setting. These should also be loaded dynamically after the app is running.
I know that once a particular bean is injected, it won't get reloaded, that doesn't concern me, it's up to that module to handle that. But I am having trouble getting the behavior I want. In particular, I have implemented an AbstractConfiguration from apache commons configuration to get the dual source and overriding I am after. But while it works for injecting the properties object, expressions loaded with "${prop.name}" don't work at all.
How can I get them to work? Did I override the wrong thing? Is it just some config detail?
<bean id="sysProperties" class="org.springframework.beans.factory.config.MethodInvokingFactoryBean">
<property name="targetObject" ref="databaseConfigurator" />
<property name="targetMethod" value="getProperties"/>
</bean>
<bean id="databaseConfigurator" class="my.util.config.MyDatabaseConfigurator">
<property name="datasource" ref="dataSource" />
<property name="propertyFile" value="/WEB-INF/my.properties" />
<property name="applicationName" value="ThisApp" />
</bean>
<bean id="dbConfigFactory" class="org.apache.commons.configuration.ConfigurationConverter" factory-method="getProperties">
<constructor-arg ref="databaseConfigurator" />
</bean>
I haven't tested this, but I think it might work.
<bean id="sysProperties" class="org.springframework.beans.factory.config.MethodInvokingFactoryBean">
<property name="targetObject" ref="databaseConfigurator" />
<property name="targetMethod" value="getProperties"/>

</bean>

I believe need help compiling Heritrix decide rules, although I'm open to other Heritrix suggestions: https://webarchive.jira.com/wiki/display/Heritrix/Configuring+Crawl+Scope+Using+DecideRules
I need to scrape an entire copy of a website (in the crawler-beans.cxml seed list), but not scrape any external (off-site) pages. Any external resources needed to render the current website should be downloaded, however not following any links to off-site pages - only the assets for the current page/domain.
For example, CDN content required for the rendering of a page might be hosted on an external domain (maybe AWS or Cloudflare), so I would need to download that content, as well as following all on-domain links, however not follow any links to pages outside of the scope of the current domain.
You could use 3 decide rules:
The first one accepts all non-html pages, using a ContentTypeNotMatchesRegexDecideRule;
The second one accepts all urls in the current domain.
The third one rejects all pages not in the domain and not directly
reached from the domain (the alsoCheckVia option)
So something like that:
<bean id="scope" class="org.archive.modules.deciderules.DecideRuleSequence">
<property name="rules">
<list>
<!-- Begin by REJECTing all... -->
<bean class="org.archive.modules.deciderules.RejectDecideRule" />
<bean class="org.archive.modules.deciderules.ContentTypeNotMatchesRegexDecideRule">
<property name="decision" value="ACCEPT"/>
<property name="regex" value="(?i)html|wml"/>
</bean>
<bean class="org.archive.modules.deciderules.surt.SurtPrefixedDecideRule">
<property name="decision" value="ACCEPT"/>
<property name="surtsSource">
<bean class="org.archive.spring.ConfigString">
<property name="value">
<value>
http://(org,yoursite,
</value>
</property>
</bean>
</property>
</bean>
<bean class="org.archive.modules.deciderules.surt.NotSurtPrefixedDecideRule">
<property name="decision" value="REJECT"/>
<property name="alsoCheckVia" value="true"/>
<property name="surtsSource">
<bean class="org.archive.spring.ConfigString">
<property name="value">
<value>
http://(org,yoursite,
</value>
</property>
</bean>
</property>

</list>

I asked a related question in Crawling rules in heritrix, how to load embedded content? and came up with a solution there. Later I found this post as well. I am submitting my solution here as well:
Note: I know the question is old so it was most likely made for an older heritrix version. I am using 3.4
<bean id="scope" class="org.archive.modules.deciderules.DecideRuleSequence">
<property name="rules">
<list>
<bean class="org.archive.modules.deciderules.AcceptDecideRule" />
<bean class="org.archive.modules.deciderules.NotMatchesListRegexDecideRule">
<property name="decision" value="REJECT"/>
<property name="regexList">
<list>
<value>.*site\.domain/path/.*</value>
</list>
</property>
</bean>
<bean class="org.archive.modules.deciderules.HopsPathMatchesRegexDecideRule">
<property name="decision" value="ACCEPT"/>
<property name="regex" value="(E|X)" />
</bean>
<!-- Below are some of the "standard" rules set up on a fresh job, it behaves the same with and without them when it comes to not loading embedded stuff -->
<bean class="org.archive.modules.deciderules.TooManyHopsDecideRule">
<!-- <property name="maxHops" value="20" /> -->
</bean>
<!-- ...and REJECT those with suspicious repeating path-segments... -->
<bean class="org.archive.modules.deciderules.PathologicalPathDecideRule">
<!-- <property name="maxRepetitions" value="2" /> -->
</bean>
<!-- ...and REJECT those with more than threshold number of path-segments... -->
<bean class="org.archive.modules.deciderules.TooManyPathSegmentsDecideRule">
<!-- <property name="maxPathDepth" value="20" /> -->
</bean>
<!-- ...but always ACCEPT those marked as prerequisitee for another URI... -->
<bean class="org.archive.modules.deciderules.PrerequisiteAcceptDecideRule">
</bean>
<!-- ...but always REJECT those with unsupported URI schemes -->
<bean class="org.archive.modules.deciderules.SchemeNotInSetDecideRule">
</bean>
</list>
</property>
</bean>
Adjust <value>.*site\.domain/path/.*</value> to match you site, and path if any.
You can also adjust <property name="regex" value="(E|X)" /> where E|X can be just E if you just want the known included things in the page, like images, css etc. X is a bit experimental for trying things found in javascript files as well.
I'm looking the way how to control java properties during installation procedure.
I'm have Spring Data JPA + Hibernate in my application. I've configured jpa properties in bean. And move it to property file.
<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="persistenceXmlLocation" value="classpath*:META-INF/persistence.xml"></property>
<property name="persistenceUnitName" value="hibernatePersistenceUnit"/>
<property name="dataSource" ref="dataSource"/>
<property name="jpaVendorAdapter">
<bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter" />
</property>
<property name="jpaPropertyMap">
<map>
<entry key="hibernate.hbm2ddl.auto" value="${hibernate.hbm2ddl}"/>
<entry key="hibernate.show_sql" value="${hibernate.show.sql}" />
<entry key="hibernate.dialect" value="${hibernate.dialect}" />
</map>
</property>
</bean>
property file: prop-local-override.properties where local is environment variable.
hibernate.hbm2ddl=update
#hibernate.dialect=org.hibernate.dialect.HSQLDialect
hibernate.show.sql=true
So, everything works fine. But I want to change hibernate.hbm2ddl during installation process. I use rpm package for installation my app. For example, I want to set this property to "create" when app is installing. And return to update after each restart.
Looks like -Dhibernate.hbm2ddl=update works fine. But it's manual work. Does anyone has some idea how to make it automatically, without big tools like Puppet?
Thanks,
Sergii K.
Never tried changing this dynamically before, but you can access that property map from your entity manager:
entityManager.getEntityManagerFactory().getProperties()
Has anyone been able to get the EclipseLink JPA povider working in WAS Liberty Profile with Container Managed Transactions? I have configured my server.xml file with the JPA Container setting to override the default OpenJPA implementations however this causes a side effect where by the EntityManager no longer participates in a Container transaction when accessed through an EJB that has a transaction propagation annotation.
I also tried setting the "eclipselink.target-server" property to "WebSpeher_7" however when I do this I get a ClassNotFoundException on the com.ibm.ws.Transaction.TransactionManagerFactory class.
Good afternoon. This looks like you're hitting Bug 407279 (https://bugs.eclipse.org/bugs/show_bug.cgi?id=407279).
You can work around this issue by modifying org.eclipse.persistence.transaction.was.WebSphereTransactionController with the following change:
public class WebSphereTransactionController extends JTATransactionController {
// Class and method to execute to obtain the TransactionManager
protected final static String TX_MANAGER_FACTORY_CLASS = "com.ibm.tx.jta.TransactionManagerFactory";
// OLD VALUE --> "com.ibm.ws.Transaction.TransactionManagerFactory";
Hope this helps! Be sure to grab EclipseLink 2.5.2 as that has another important change (Bug 412627) in order to work with Liberty!
I had to change many things with liberty 16.0.0.2, Spring 4.X and EclipseLink 5.2.X
I removed the persistence.xml file
and changed the spring xml configuration to:
<bean id="transactionManager"
class="org.springframework.orm.jpa.JpaTransactionManager">
<property name="entityManagerFactory" ref="entityManagerFactory" />
</bean>
<bean id="entityManagerFactory"
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="dataSource" ref="datasource" />
<property name="persistenceUnitName" value="PERSISTENCE_UNIT"></property>
<property name="jpaVendorAdapter" ref="jpaVendorAdapter" />
<property name="packagesToScan">
<list>
<value>ENTITIES_PACKAGE</value>
</list>
</property>
<property name="jpaPropertyMap">
<map>
<entry key="eclipselink.weaving" value="false"/>
</map>
</property>
</bean>
And for server.xml
<jpa defaultPersistenceProvider="org.eclipse.persistence.jpa.PersistenceProvider"/>
