聲納上的java.lang.ClassCastException

最近我被分配到使用Sonar和Maven來檢查Java代碼覆蓋率。我運行mvn sonar:sonar，構建出來就好，再加上我可以看到儀表板的結果。聲納上的java.lang.ClassCastException

但是，測試用例出現錯誤，如果我正常運行它，根本不會發生。以下是錯誤堆棧跟蹤：

$Proxy11 cannot be cast to com.epsilon.agility.message.dao.MessageDAO 
java.lang.ClassCastException: $Proxy11 cannot be cast to     com.epsilon.agility.message.dao.MessageDAO

這裏參與了錯誤的方法：

@BeforeClass 
@Transactional(propagation = Propagation.REQUIRED, timeout = 10) 
public static void setUp() throws IOException { 
    conn = TestDBUtils.getDBConnection(); 

    MessageDBAdaptorService.init(conn); 

    msgclassificationFacade = new MessageClassificationFacadeImpl(conn); 

    messageDAO = MessageDBAdaptorService.getMessageDAO(); 
    messageAssetDAO = MessageDBAdaptorService.getMessageAssetDAO(); 
    channelDAO = MessageDBAdaptorService.getChannelDAO(); 
    folderItemDAO = MessageDBAdaptorService.getFolderItemDAO(); 
    folderDAO = MessageDBAdaptorService.getFolderDAO(); 


    Assert.assertNotNull(messageDAO); 
    Assert.assertNotNull(messageAssetDAO); 
    Assert.assertNotNull(channelDAO); 
    Assert.assertNotNull(folderItemDAO); 
    Assert.assertNotNull(folderDAO); 

}

我搜索的解決方案，在線，但它似乎沒有聲納沒有類似的解決方案。我懷疑問題可能來自測試用例的Sonar不同方法，因爲測試用例正常運行正常。

如果以上不足，我會發布更多的代碼和信息。謝謝你的幫助。
