Question

I am new to SpringBoot. I am writing a project in SpringBoot(along with Hibernate)
while accessing the database, I am getting following error:
org.hibernate.hql.internal.ast.QuerySyntaxException: HashMapping is not mapped [from HashMapping where consumerUserId=:consumerUserId]

My Application configuration class is as follows:
import org.hibernate.SessionFactory;
import org.hibernate.jpa.HibernateEntityManagerFactory;
import org.springframework.boot.SpringApplication;

}
public static void main(String[] args) {
SpringApplication.run(Application.class, args);

}
The Dao is as follows:
#Override
public String userHashExists(Long consumerUserId) throws Exception{
Session session = null;
try {
session = factory.openSession();
Query query = session.createQuery("from HashMapping where consumerUserId=:consumerUserId");
query.setParameter("consumerUserId", consumerUserId);
HashMapping mapping = (HashMapping) query.uniqueResult();
if(mapping!=null)
return mapping.getConsumerHash();
return null;
} catch(Exception e){
logger.error("Exception in userHashExists Dao", e);
throw e;
} finally {
if(session!=null) {
session.close();
}
}
}

}
Can someone please help where I am going wrong.
DO I need to define something like <hibernate-mapping package="it.besmart.models"> as we do in spring servelet configuration. If yes how to do it in my existing code?

Answer 1

Answering where I was going wrong.
Add #EntityScan(basePackages = { "youentitypackage" }) along with #ComponentScan(basePackages = { "com.app" }). This will look for your entity classes.

Answer 2

I think this mistake "Query query = session.createQuery("from HashMapping where consumerUserId=:consumerUserId");"When make a request to the database,need add "SELECT" your entity in table WHERE....
OR "HashMapping" to "hash_mapping" (class entity must be same name as database)
