Hello

I'm studying Spring and I'm having the following problem to upload the project to tomcat8. My dependencies are not being injected, but I'm not able to identify what's missing.

My problem was a lack of attention with my class to get a Hibernate Session.

As I was 

@Repository
public abstract class HibernateSession {

    @Autowired
    private SessionFactory sessionFactory;

    @Autowired
    protected Session getSession() {
        return sessionFactory.getCurrentSession();
    }
}

Changed 

@Repository
public abstract class HibernateSession {

    @Autowired
    private SessionFactory sessionFactory;

    protected Session getSession() {
        return sessionFactory.getCurrentSession();
    }
}

Thanks for the help utluiz.

The original cause of the problem is in the last log exception:

  

Caused by: org.hibernate.HibernateException: Could not get transaction-synchronized Session for current thread

Injection error was not caused by lack of classes as ClassNotFoundException , which would be a symptom of dependency problems.

This is caused because Spring was unable to get a transaction for the classes where you used @Transactional , so you could not create them correctly and all classes that depend on it will not be created either.

I saw that you have correctly set up transactions in your XML using <tx:annotation-driven/> , which is usually the cause of this error, so the problem is elsewhere.

Unfortunately, I can not see why Spring was unable to create the documentation, but may have something to do with failing to connect to the bank or pool.

I suggest removing the transaction log and see if it works without it.

It would also help increase the level of logging and repair if any alert or error of any kind occurs before then. Some time ago I had some colleagues having strange problems with the database and when I analyzed the log carefully I saw that Spring Boot was not ignoring the database settings and creating a bank in memory. This is because the configuration file was not in the correct place in the project.

If you can get any more information, please edit your question and I'll try to help you more.

Finally, I suggest using the HirakiCP to manage the connection pool. It has much better performance and stability than older libraries like Apache DBCP and C3P0.
