java.lang.IllegalStateException：JUNITでApplicationContextをロードできませんでした

Question

ユニットテストケースの実行中にJUnitに問題が発生しました。私はSpring 4とJUnit 4を使用しています。なぜこの例外が発生するのか分かりませんでした私はコードを実行するためのすべての可能な方法を試しましたが、私はテストケースを実行できませんでした。 No qualifying bean of type [org.springframework.mail.javamail.JavaMailSenderImpl]：

@RunWith(SpringJUnit4ClassRunner.class) 
    @WebAppConfiguration 
    @ContextConfiguration(classes = SampleConfiguration.class) 
    @SuppressWarnings("unused") 
    public class JunitSampleDetails { 
     @ClassRule 
     public static final JunitDataSource DATA_SOURCE = new JunitDataSource(); 
     @Autowired 
     private XyzDetailsService xyzDetailsService; 
     @Autowired 
     private JavaMailSenderImpl javaMailSenderImpl;

を実行している間、私は次の例外を取得していますが主な理由を参照してください。

com.sample.controller.XYZDetailsControllerはクラスパスにないか、私はすでにこの@Autowired \tプライベート\t JavaMailSenderImpl javaMailSenderImplを追加
