Could not autowire field: private javax.sql.DataSource - spring

Question

I have a simple jpa based spring boot project
#EnableJpaRepositories(basePackages = "de.dahilein.resourcecal.repos")
#Configuration
#ComponentScan
#EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class})
public class ResourceCalApplication {
public static void main(String[] args) {
SpringApplication.run(ResourceCalApplication.class, args);
}
#Bean
public LocalEntityManagerFactoryBean entityManagerFactory() {
EntityManagerFactory emf = Persistence.createEntityManagerFactory("resourcecal");
return emf;
}
#Bean
public PlatformTransactionManager transactionManager() {
JpaTransactionManager transactionManager = new JpaTransactionManager();
transactionManager.setEntityManagerFactory(entityManagerFactory());
return transactionManager;
}
}
I get the following stack trace
01:16:50.072 [localhost-startStop-1] ERROR o.s.web.context.ContextLoader - Context initialization failed

Without it I get:
My datasource is jndi, name is set in persistence.xml
<persistence version="2.1" xmlns="http://xmlns.jcp.org/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd">
<persistence-unit name="resourcecal" transaction-type="RESOURCE_LOCAL">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<non-jta-data-source>java:comp/env/jdbc/resourcecalDS</non-jta-data-source>
And the DS is defined in server.xml and linked to context.xml using a ResourceLink. This all seems to work because if I remove the DS or change the jndi names to test it reacts accordingly.
I see various logs that it is picking up the persistence.xml
01:54:27.223 [localhost-startStop-2] DEBUG o.h.jpa.internal.util.LogHelper - PersistenceUnitInfo [
name: resourcecal
persistence provider classname: org.hibernate.ejb.HibernatePersistence
classloader: null
and the jndi name.
What am I missing?

Answer 1

You need to create a bean in your configuration like this:
#Bean
public DataSource dataSource() {
final JndiDataSourceLookup jndiDataSource= new JndiDataSourceLookup();
jndiDataSource.setResourceRef(true);
DataSource dataSource = jndiDataSource.getDataSource("jdbc/resourcecalDS");
return dataSource;
}

Answer 2

I had faced same problem, in my case i had used spring boot dependency version 1.4.0 and also tried latest one but i had changed that to
<version>2.0.5.RELEASE</version>
"2.0.5"..
So check it if you have done same mistake then re-correct to it.
