How to extract Hibernate DB records with Spring initialized in main method of the application

Question

I would like to convert code from https://github.com/mattnworb/hibernate-sample

so that it would not run from test directory, but from src dir, as a class with method main. In tests the dbunit database in xml file is correclty read.

I can see several problems with transforming tests to app:

Tests are run with SpringJUnit4ClassRunner and test classes extend AbstractTransactionalJUnit4SpringContextTests. Applying this to class with main method resulted in context initialization exception.
In Java main method is always static. If I try to inject fields like

@Autowired private SomeClass instance;

Then I cannot call it in main class, since injected field is not static (and cannot be)

What could be the solution?

No. Do I need to go Spring Boot? I don't need Tomcat in my application — Krzysztof

You can just create application context object in your main class and get there bean :

ConfigurableApplicationContext ctx = new AnnotationConfigApplicationContext(“your.package.of.beans”);
 // you are passing here the package where beans  are located  

  YourClass yourClass = ctx.getBean(YourClass.class);
