title: Spring 3 and JUnit 4 (autowiring)
body: <p>I am new to Spring MVC and JUnit. Basically I want to autowire the service class and this class should be loaded in spring context.</p>
  
  <p>Service</p>
  
  <pre>
  
      @Service 
      public class FundService  {
          @Autowired
          FundDAO fundDAO;
  
          /**
           * @return
           */
          public List getFundDetails(String productId) {
  
              return fundDAO.getFundDetails(productId);
          }   
      }
  
  </pre>
  
  <p>application-context</p>
  
  <pre><code>&lt;beans&gt;
  
      &lt;mvc:annotation-driven /&gt;
  
      &lt;context:component-scan base-package="com.test.*" /&gt;
  &lt;/beans&gt;
  </code></pre>
  
  <p>Junit class </p>
  
  <pre>
  
      @RunWith(SpringJUnit4ClassRunner.class)
      @ContextConfiguration(locations={"classpath*:/WEB-INF/application-context.xml"})
      public class CompensationServiceTest {
  
          @Autowired
          private FundService fundService;
  
          @Test
          public void verifyGetCompensationList()
          {
              System.out.println(fundService == null);
          }
      }
  
  </pre>
  
  <p>While executing the test I am getting following exception trace</p>
  
  <pre>
