JavaConfig - Spring JPA Hibernate - #EnableTransactionManagement - spring

Question

I am trying to setup a demo project with Spring4, Hibernate and a HSQLDB-Database with a JavaConfig and a Tomcat8-Server. I followed several tutorials but all ends up in the same exception.
Here is my Configuration:
#Configuration
#EnableTransactionManagement
#Slf4j
public class DatasourceConfig
{
#Bean
DataSource dataSource()
{
DataSource dataSource = null;
JndiTemplate jndi = new JndiTemplate();
try
{
dataSource = (DataSource) jndi.lookup("java:comp/env/jdbc/testdb");
}
catch (NamingException e)
{
log.error(e.toString());
}
return dataSource;
}
#Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactoryBean()
{
LocalContainerEntityManagerFactoryBean entityManagerFactoryBean = new LocalContainerEntityManagerFactoryBean();
entityManagerFactoryBean.setDataSource(dataSource());
entityManagerFactoryBean.setPackagesToScan("packageNameWithModels");
JpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
entityManagerFactoryBean.setJpaVendorAdapter(vendorAdapter);
entityManagerFactoryBean.setJpaProperties(hibProperties());
return entityManagerFactoryBean;
}
#Bean
public PlatformTransactionManager transactionManager()
{
JpaTransactionManager transactionManager = new JpaTransactionManager();
transactionManager.setEntityManagerFactory(entityManagerFactoryBean().getObject());
return transactionManager;
}
#Bean
public PersistenceExceptionTranslationPostProcessor exceptionTranslation(){
return new PersistenceExceptionTranslationPostProcessor();
}
private Properties hibProperties()
{
Properties properties = new Properties();
properties.put("hibernate.dialect", "org.hibernate.dialect.HSQLDialect");
properties.put("hibernate.show_sql", "true");
return properties;
}
}
Maven install works like a charm but when I try to start the tomcat8-Server I get the follow error:

In my understanding the #EnableTransactionManagment-annotation searches for a transaction-manager bean, finds it but is not able to find the entity manager that is set by code:
transactionManager.setEntityManagerFactory(entityManagerFactoryBean().getObject());
Maybe someone can help me out?
Thanks in advance
Pete

Answer 1

Not sure what is the issue with your setup. Please try this setup. Remove your entityManagerFactoryBean, transactionManager and hibProperties methods.
#Bean
#Autowired
public EntityManagerFactory entityManagerFactory(DataSource dataSource) {
HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
vendorAdapter.setGenerateDdl(false);
LocalContainerEntityManagerFactoryBean factory = new LocalContainerEntityManagerFactoryBean();
factory.setJpaVendorAdapter(vendorAdapter);
factory.setPackagesToScan("com.company.project");
factory.setDataSource(dataSource);
Properties jpaProperties = new Properties();
jpaProperties.put("hibernate.dialect", "org.hibernate.dialect.HSQLDialect");
jpaProperties.put("hibernate.show_sql", true);
factory.setJpaProperties(jpaProperties);
factory.afterPropertiesSet();
return factory.getObject();
}
#Bean
#Autowired
public PlatformTransactionManager transactionManager(EntityManagerFactory entityManagerFactory) {
JpaTransactionManager jpaTransactionManager = new JpaTransactionManager(entityManagerFactory);
return jpaTransactionManager;
}

Answer 2

I found the problem, I had an outdated dependency in pom.xml defined:
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-dao</artifactId>
<version>2.0.8</version>
</dependency>
After I removed this dependency it works.
Anyways, thanks a lot for helping!
