Spring 3.1 - Mixed configuration

[srikanthvishwanath]

Hello,

I am trying to convert a portion of my configuration into Java configuration and the configuration class looks like this -

@Configuration
public class AppConfig {

@Bean
public org.springframework.orm.jpa.LocalContainerEntityMa nagerFactoryBean entityManagerFactory(){
org.springframework.orm.jpa.LocalContainerEntityMa nagerFactoryBean entityManagerFactory = new org.springframework.orm.jpa.LocalContainerEntityMa nagerFactoryBean();
entityManagerFactory.setDataSource(dataSource());
entityManagerFactory.setPersistenceUnitName("App1" );
entityManagerFactory.setJpaDialect(jpaDialect());
entityManagerFactory.setJpaVendorAdapter(jpaVendor Adapter());
entityManagerFactory.setPersistenceXmlLocation("/WEB-INF/persistence.xml");
return (LocalContainerEntityManagerFactoryBean) entityManagerFactory.getObject();


}

@Bean
public DataSource dataSource() {
org.springframework.jndi.JndiObjectFactoryBean dataSource = new org.springframework.jndi.JndiObjectFactoryBean();
dataSource.setJndiTemplate(jndiTemplate());
dataSource.setJndiName("java:comp/env/jdbc/app1_datasource");
return (DataSource) dataSource.getObject();

}

@Bean
public org.springframework.jndi.JndiTemplate jndiTemplate(){
org.springframework.jndi.JndiTemplate jndiTemplate = new org.springframework.jndi.JndiTemplate();
Properties environment = Environment.getProperties();
environment.setProperty("java.naming.factory.initi al", "weblogic.jndi.WLInitialContextFactory");
environment.setProperty("java.naming.provider.url" , "t3://localhost:7001");
jndiTemplate.setEnvironment(environment);
return jndiTemplate;
}

@Bean
public JpaDialect jpaDialect(){
org.springframework.orm.jpa.vendor.HibernateJpaDia lect jpaDialect = new org.springframework.orm.jpa.vendor.HibernateJpaDia lect();
return jpaDialect();
}

@Bean
public org.springframework.orm.jpa.vendor.HibernateJpaVen dorAdapter jpaVendorAdapter(){
org.springframework.orm.jpa.vendor.HibernateJpaVen dorAdapter vendorAdapter = new org.springframework.orm.jpa.vendor.HibernateJpaVen dorAdapter();
vendorAdapter.setDatabasePlatform("org.hibernate.d ialect.SQLServerDialect");
vendorAdapter.setGenerateDdl(true);
vendorAdapter.setShowSql(true);
return vendorAdapter;
}

@Bean
public org.springframework.flex.core.io.JpaHibernateConfi gProcessor jpaConfigProcessor(){
org.springframework.flex.core.io.JpaHibernateConfi gProcessor jpaConfigProcessor = new org.springframework.flex.core.io.JpaHibernateConfi gProcessor();
jpaConfigProcessor.setEntityManagerFactory(null);
return jpaConfigProcessor;
}
}

but when I try to use this configuration to startup my application -

I get this exception -

org.springframework.beans.factory.BeanCreationExce ption: Error creating bean with name 'remoteService' defined in file [D:\STS26\workspace\app1\WebContent\WEB-INF\classes\com\appDAOclass]: BeanPostProcessor before instantiation of bean failed; nested exception is org.springframework.beans.factory.BeanCreationExce ption: Error creating bean with name 'org.springframework.transaction.config.internalTr ansactionAdvisor': Cannot resolve reference to bean 'org.springframework.transaction.annotation.Annota tionTransactionAttributeSource#0' while setting bean property 'transactionAttributeSource'; nested exception is org.springframework.beans.factory.BeanCreationExce ption: Error creating bean with name 'org.springframework.transaction.annotation.Annota tionTransactionAttributeSource#0': BeanPostProcessor before instantiation of bean failed; nested exception is org.springframework.beans.factory.BeanCreationExce ption: Error creating bean with name 'auditAdvisor' defined in ServletContext resource [/WEB-INF/app-servlet.xml]: Cannot resolve reference to bean 'testAdvice' while setting bean property 'advice'; nested exception is org.springframework.beans.factory.BeanCreationExce ption: Error creating bean with name 'testAdvice': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationExce ption: Could not autowire field: private com.dao.TestDAO com.aop.testAdvice.TestDAO; nested exception is org.springframework.beans.factory.BeanCreationExce ption: Error creating bean with name 'entityManagerFactory' defined in class path resource [com/AppConfig.class]: Instantiation of bean failed; nested exception is org.springframework.beans.factory.BeanDefinitionSt oreException: Factory method [public org.springframework.orm.jpa.LocalContainerEntityMa nagerFactoryBean com.AppConfig.entityManagerFactory()] threw exception; nested exception is java.lang.IllegalArgumentException: DataSource must not be null

Can someone let me know if something is missing?

Thanks & Regards

Please use [ code][/code ] tags when posting code, that way it remains readable ...

You should call the afterPropertiesSet method on the JndiObjectFactoryBean before calling getObject.

Hello,

I am facing this problem of assigning the datasource to EntityManagerFactory definition.

When I use the XML configuration

<bean id="entityManagerFactory"
		class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
		<property name="persistenceUnitName" value="Test" />
		<property name="dataSource" ref="dataSource" />
		<property name="jpaDialect" ref="jpaDialect" />
		<property name="jpaVendorAdapter" ref="vendorAdapter" />
		<property name="persistenceXmlLocation" value="/WEB-INF/persistence.xml"/>
	</bean>

<bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
			<property name="jndiTemplate" ref="jndiTemplate"/>
		<property name="jndiName">
		 <value>java:comp/env/jdbc/test_datasource</value>
		 </property>
	</bean>

everything works fine. But when I try to do the same in Java config as mentioned earlier it fails to accept the datasource -

@Bean
    public EntityManagerFactory entityManagerFactory(){
    	org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean entityManagerFactory = new org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean();
    	entityManagerFactory.setDataSource(dataSource());
    	entityManagerFactory.setPersistenceUnitName("test");
    	entityManagerFactory.setJpaDialect(jpaDialect());
    	entityManagerFactory.setJpaVendorAdapter(jpaVendorAdapter());
    	entityManagerFactory.setPersistenceXmlLocation("/WEB-INF/persistence.xml");
    	return (EntityManagerFactory) entityManagerFactory.getObject();
    
    	
    }

  @Bean
    public DataSource dataSource() { 
    	org.springframework.jndi.JndiObjectFactoryBean dataSource = new org.springframework.jndi.JndiObjectFactoryBean();
    	try{
    	
    	dataSource.setJndiTemplate(jndiTemplate());
    	dataSource.setJndiName("java:comp/env/jdbc/test_datasource");
    	dataSource.afterPropertiesSet();
    	
    	
    	}
    	catch(Exception e){
    		
    	}
    	return (DataSource)dataSource;
}

Can you please let me know if I am missing something?

Also, how do I use @ExternalBean with Spring 3.1?

Thanks
SK

Have you actually read my post????

You should call the afterPropertiesSet method on the JndiObjectFactoryBean before calling getObject.

Thanks Marten I had missed this as well.
