Defining HibernateExceptionTranslator: No persistence exception translators found in bean factory

Question

I am trying to inject a eventRepository which is Spring Data Repository in my project:

public class App {

    protected static EntityManagerFactory factory;

    @Autowired
    protected EventRepository eventRepository;

    public void execute() {
        Event foo = eventRepository.findBySlug("abraxas");
    }

    public static void main(String[] args) {
        ApplicationContext context =
                new ClassPathXmlApplicationContext("beans.xml");

        App runner = (App) context.getBean("AppBean");
        runner.execute();
    }
}

beans.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:jpa="http://www.springframework.org/schema/data/jpa"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
            http://www.springframework.org/schema/beans/spring-beans.xsd
            http://www.springframework.org/schema/data/jpa
            http://www.springframework.org/schema/data/jpa/spring-jpa.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd">

    <bean id="AppBean" class="org.app.App"></bean>
    <jpa:repositories base-package="org.app.repository" />
</beans>

But when I run it I get following exception:

java.lang.IllegalStateException: No persistence exception translators found in bean factory. Cannot perform exception translation.
at org.springframework.dao.support.PersistenceExceptionTranslationInterceptor.detectPersistenceExceptionTranslators

In some comments I found I need to "configure HibernateExceptionTranslator", but I did not manage to find out how.

I am trying to follow the official documentation which does not mention configuration of HibernateExceptionTranslator.

Thanks

Solution 1

Obviously the solution was adding

     <bean class="org.springframework.orm.hibernate4.HibernateExceptionTranslator"/>

to beans.xml

Solution found thanks to JB Nizet.

Solution 2

With Java Config:

@Bean
public HibernateExceptionTranslator hibernateExceptionTranslator() {
    return new HibernateExceptionTranslator();
}

Using this import if using Hibernate 3:

import org.springframework.orm.hibernate3.HibernateExceptionTranslator;

or this one if using Hibernate 4:

import org.springframework.orm.hibernate4.HibernateExceptionTranslator;
