I have web MVC written using Spring. I used separate dao and service classes.
My old code:
#Repository
public class RoleDaoImpl implements RoleDao {
...
}
#Service
#Transactional
public class RoleManagerImpl implements RoleManager {
...
}
#Controller
public class HomeController {
#Autowired
private RoleManager roleManager;
...
}
Now I would like to try Spring JPA. But I can't rewrite my testing project from dao-service to Spring JPA.
There is project source on github https://github.com/martin159/springjpa
After I run project I get following error:
WARN : org.springframework.web.context.support.XmlWebApplicationContext - Exception encountered during context initialization - cancelling refresh attempt
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in ServletContext resource [/WEB-INF/spring-servlet.xml]: Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: No PersistenceProvider specified in EntityManagerFactory configuration, and chosen PersistenceUnitInfo does not specify a provider class name either

I spend a lot of hours with Spring JPA, but I still can't to fix it.
Do you have any idea what I do bad?
I think this is because you specified LocalContainerEntityManagerFactoryBean without telling spring what's your persistence unit name is. Hence Spring will use the default one.
<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
Meanwhile in persistence.xml, you specified your persistence unit name is springjpa
<persistence-unit name="springjpa" transaction-type="JTA">
Try
<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="persistenceUnitName" value="springjpa"/>
</bean>

I have upgraded hibernate 3.x to 5.2.1 in my application. After upgrade, I am getting following error when I run my application,

I have google to find the solution. I came to know as Hibernate StatisticsService is deprecated from 4.0 and removed in hibernate 5.2.1.
Refer - https://stackoverflow.com/a/23606322 and https://docs.jboss.org/hibernate/orm/4.0/javadocs/deprecated-list.html
I am using spring 4.3.2 version with hibernate 5.2.1 for my application.
What is the quick workaround or replacement for org.hibernate.jmx.StatisticsService ?
Kindly help.
As a work around they suggest to use your own spring bean. From Hibernate JIRA HHH-6190
public class HibernateStatisticsFactoryBean implements FactoryBean<Statistics> {
#Autowired
private EntityManagerFactory entityManagerFactory;
#Override
public Statistics getObject() throws Exception {
SessionFactory sessionFactory = ((HibernateEntityManagerFactory) entityManagerFactory).getSessionFactory();
return sessionFactory.getStatistics();
}
#Override
public Class<?> getObjectType() {
return Statistics.class;
}
#Override
public boolean isSingleton() {
return true;
}
}
Then you can export this as MBean: From Spring Doc
By default, the Hibernate statistics mechanism is not enabled, so you need to activate it using the following configuration property:
<property name="hibernate.generate_statistics" value="true"/>
To expose the Hibernate metrics via JMX, you also need to set the hibernate.jmx.enabled configuration property:
<property name="hibernate.jmx.enabled" value="true"/>
It is recommended to use Hibernate 5.4.2+ this mechanism seem broken in previous version.

I don't no the exact reason, why it acts different from cmd and through eclipse , but i given a try by running the mvn commands from the cmd then after through the eclipse IDE. then it is working fine.
I recently encountered this error. It was resolved when I changed the spring-boot-starter-parent version to a more updated version.
So whenever you are sure of your dependency yet you get errors, I'd suggest you check the version of the dependency too.
I am trying to move my simple spring integration application from XML context to Groovy contex. Unfortunately, a couldn't find any useful examples how to work with namespaces in Groovy context. I started from the simplest part, inbound gateway binded with MQ:
<bean id="jmsFactory" class="org.apache.activemq.pool.PooledConnectionFactory" destroy-method="stop">
<property name="connectionFactory">
<bean class="org.apache.activemq.ActiveMQConnectionFactory">
<property name="brokerURL" value="<brokerUrl>"/>
</bean>
</property>
</bean>
<int:channel id="plainRequestChannel"/>
<int:channel id="errorChannel"/>
<int:channel id="plainReplyChannel"/>
<int-jms:inbound-gateway id="gateway" request-destination-name="QUEUE.IN"
default-reply-queue-name="QUEUE.OUT"
request-channel="plainRequestChannel"
error-channel="errorChannel"
reply-channel="plainReplyChannel"
connection-factory="jmsFactory"/>
My Groovy equivalent of this context (doesn't work):
package spring4
import org.apache.activemq.jms.pool.PooledConnectionFactory
import org.apache.activemq.spring.ActiveMQConnectionFactory;
beans {
xmlns intjms:"http://www.springframework.org/schema/integration/jms"
xmlns integration:"http://www.springframework.org/schema/integration"
amqConnectionFactory (ActiveMQConnectionFactory) {
brokerURL = "<brokerUrl>"
}
jmsFactory (PooledConnectionFactory) {bean ->
bean.destroyMethod = 'stop'
connectionFactory = ref('amqConnectionFactory')
}
integration.channel(id:'plainRequestChannel')
integration.channel(id:'plainReplyChannel')
integration.channel(id:'errorChannel')
intjms.'inbound-gateway'(
id:"gateway",
'request-destination-name': "QUEUE.IN",
'default-reply-queueName': "QUEUE.OUT",
'request-channel': ref('plainRequestChannel'),
'error-channel': ref('errorChannel'),
'reply-channel': ref('plainReplyChannel'),
'connection-factory': ref('jmsFactory')
)
}
As I mentioned, It doesn't work. Error:

Please, what am I doing wrong? Also, I would appreciate if you recommend me any links to related tutorials/examples/docs
Have you looked at the groovy dsl?
It hasn't had much activity lately but it might give you some pointers (it has a JMS module).
You might also want to look at the new (actively maintained) Java DSL.
Well, this particular problem has been solved: I just removed ref. So my context now looks like this:
package spring4
import org.apache.activemq.jms.pool.PooledConnectionFactory
import org.apache.activemq.spring.ActiveMQConnectionFactory;
beans {
//importBeans("classpath:spring4/IntegrationProperties.groovy")
xmlns intjms:"http://www.springframework.org/schema/integration/jms"
xmlns integration:"http://www.springframework.org/schema/integration"
amqConnectionFactory (ActiveMQConnectionFactory) {
brokerURL = "<brokerUrl>"
}
jmsFactory (PooledConnectionFactory) {bean ->
bean.destroyMethod = 'stop'
connectionFactory = amqConnectionFactory
}
integration.channel(id:'plainRequestChannel')
integration.channel(id:'plainReplyChannel')
integration.channel(id:'errorChannel')
intjms.'inbound-gateway'(
id:'gateway',
'request-destination-name': "QUEUE.IN",
'default-reply-queueName': "QUEUE.OUT",
'request-channel': 'plainRequestChannel',
'error-channel': 'errorChannel',
'reply-channel': 'plainReplyChannel',
'connection-factory': 'jmsFactory'
)
}
I have a few web applications deployed on Tomcat which all use the same database access configuration from Tomcat connection pool:
<bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiName" value="java:comp/env/jdbc/postgres"/>
<property name="lookupOnStartup" value="true"/>
<property name="proxyInterface" value="javax.sql.DataSource"/>
</bean>
(web.xml in each project and context.xml in Tomcat are set properly, because everything works :)).
I would like to use this connection also with JAR files which run on the same server. In the JAR I also use Spring, but I get the following error if I use above dataSource definition in the code like this:
String[] springConfig = { "file:/var/pro/conf/data-access.xml"};
context = new ClassPathXmlApplicationContext(springConfig);
I get the following error:

This code will not work if you run it outside Tomcat, that is from main. Tomcat provides initial context factory for JNDI.
I'm new to Spring Framework so I decided to buy a book ("Spring in action" 3rd edition). Currently I'm at first chapter which covers basics - Dependency Injection (DI) and Aspect oriented programming (AOP).
I managed to run this code which showed DI.

package com.springinaction.knights;
public class BraveKnight implements Knight {
private Quest quest;
public BraveKnight(Quest quest) {
this.quest = quest; //<co id="co_injectedQuest"/>
}
public void embarkOnQuest() throws QuestException {
quest.embark();

#2Quest Exception
package com.springinaction.knights;
public class QuestException extends RuntimeException {

}
#2Quest type class implementation
package com.springinaction.knights;
public class SlayDragonQuest implements Quest {
public void embark() throws QuestException {
System.out.println("Slaying Dragon!");
}
}
#3Testing brave knight DI
package com.springinaction.knights;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class KnightMain {
public static void main(String[] args) {
ApplicationContext context =
new ClassPathXmlApplicationContext("knights.xml"); //<co id="co_loadKnightContext"/>
Knight knight = (Knight) context.getBean("knight"); //<co id="co_getBeanKnight"/>
knight.embarkOnQuest();//<co id="co_useKnight"/>
}
}
This is XML application context which injects quest into knight
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

<bean id="knight" class="com.springinaction.knights.BraveKnight">
<constructor-arg ref="quest" /> <!--<co id="co_inject_quest_bean"/> -->
</bean>
</beans>
To this moment everything works, but when author wants to show AOP then something is wrong in XML file. The idea is that minstrel sings (logs) before knight goes on a quest and sings (logs off) when knight comes back from a quest.
Minstrel class
package com.springinaction.knights;
public class Minstrel {
public void singBeforeQuest() { //<co id="co_singBefore"/>
System.out.println("Fa la la; The knight is so brave!");
}
public void singAfterQuest() { //<co id="co_singAfter"/>
System.out.println(
"Tee hee he; The brave knight did embark on a quest!");
}
}
XML AOP file, I guess there is some kind of error here, but I don't know what...

Testing this looks exactly like in #3 Testing BraveKnight
Exception which is verry long.

Download AspectJ and add aspectjrt.jar & aspectjweaver.jar to your classpath. Spring's aop config with the aop namespace is based on AspectJ, which is no more shipped bundled with org.springframework.aop jar.
Following is maven dependency in case its a maven based project
