title: @Autowired with JUnit tests
body: <p>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 always NULL.</p>
  
  <p>Here is the example code:</p>
  
  <pre><code>     public class Test {
  
                   protected ApplicationContext ac;
  
                   @Before
                   public void setUp() {
                       ac = new FileSystemXmlApplicationContext("classpath:config/applicationContext.xml"
                       "classpath:config/test-datasources.xml");
                   }
  
                   @Test
                   public void testRun() throws Exception {
                          IManager manager =  (IManager)this.ac.getBean("manager");
                          manager.doSomething();
                   }
      }
  
      @Service
      public class Manager implements IManager {
  
              public boolean doSomething() throws Exception {
                   ParametersJCSCache parametersJCSCache = new ParametersJCSCache();
                   String paramValue = parametersJCSCache.getParameter("XPTO");
                   ...
              }
      }
  
      public class ParametersJCSCache extends SpringBeanAutowiringSupport {
  
            @Autowired
            private IParameterManager parameterManager;  //THIS IS NULL
      }
  </code></pre>
  
  <p>When invoking the Manager object the Spring generates the proxy but when accessing the @Autowired parameterManager the object is null, and with this issue i can´t test this method.</p>
  
  <p>Any idea what is causing this? Why does the object not get injected? It works well in the context of a web application, but in the test context is always NULL.</p>
