Question

I´ve using JUnit but some tests have some issues, these tests have @Autowired annotation inside the Spring beans and when i reference them the beans that are @Autowired were alw

Looks to me like ParametersJCSCache is not a Spring managed bean. You need to make this a Spring bean and autowire it into the Manager

@Service
        public class Manager implements IManager {

                public boolean doSomething() throws Exception {
                     ParametersJCSCache parametersJCSCache = new ParametersJCSCache(); <-- You create a new (non Spring-managed) instance
                     String paramValue = parametersJCSCache.getParameter("XPTO");
                     ...
                }
        }

Change to:

@Service
public class Manager implements IManager {

      @Autowired
      private ParametersJCSCache  parametersJCSCache; 

        public boolean doSomething() throws Exception {
             String paramValue = parametersJCSCache.getParameter("XPTO");
             ...
        }
}

@Component
public class ParametersJCSCache extends JCSCache {

      @Autowired
      private IParameterManager parameterManager;  //THIS IS NULL
}

Try running your unit tests with a spring runner instead.

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"classpath:config/applicationContext.xml",
                 "classpath:config/test-datasources.xml"})
public class MyTest {

   @Autowired private IManager manager;

   @Test public void someTest() {
     assertNotNull(manager);
   }
}

It will load the config only once and when needed, and it will autowire your junit class

I've finally found a solution to my problem. Find this post SpringBeanAutowiringSupport does not inject beans in jUnit tests and do something like this the JUnit tests works.
