不符合所有BeanPostProcessor的處理條件的類

Question

我在設置Maven中Spring + Spring數據JPA + QueryDSL + JPA 2.0 + Hibernate的配置時遇到了很多麻煩。我已經解決了很多問題，但是這個問題讓我頭痛= /。

，我發現了以下異常：

Bean 'dataSource' of type [class org.springframework.jdbc.datasource.DriverManagerDataSource] is not eligible for getting processed by all BeanPostProcessors (for example: not eligible for auto-proxying) 

我參加了谷歌一看，大部分的時候這個問題是由缺少註釋「@Transactional」引起的。我試圖註釋我的方法，但它沒有解決任何問題。我absolutelly沒有關於它來自何方=（想法

這裏是我的測試代碼：。

@RunWith(SpringJUnit4ClassRunner.class) 
@ContextConfiguration(locations="/applicationContext.xml") 
public class BaseTest { 

    public BaseTest() { 
    } 

    @Before 
    public void setUp() throws IOException { 
     Dataset.loadDatabase(); 
    } 

    @Test 
    public void load(){} 
} 

類數據集只是做的分貝一些節約，看看它的工作

我的applicationContext.xml：

Answer 1

這一警告意味着什麼，你不應該擔心，因爲你不需要任何申請後處理器的DataSource。從技術上講，這意味着某些bean後處理器（我猜想是一個事務處理器）取決於您的DataSource，因此DataSource必須在該後處理器初始化之前完全初始化，以便後處理器不能截獲初始化的DataSource。

如果您想要應用後處理器的bean有這樣的警告，您需要擔心。
