Class not eligible for getting processed by all BeanPostProcessors
提问by Tiago Peres Fran?a
I'm having a lot of trouble to set up a configuration of Spring + Spring Data JPA + QueryDSL + JPA 2.0 + Hibernate in Maven. I already solved a lot of problems, but this one is giving me headache =/.
我在 Maven 中设置 Spring + Spring Data JPA + QueryDSL + JPA 2.0 + Hibernate 的配置时遇到了很多麻烦。我已经解决了很多问题，但是这个问题让我头疼=/。
I'm getting the following exception:
我收到以下异常：
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)
I took a look in Google and most of times this problem is caused by the absence of the annotation "@Transactional". I tried to annotate my methods, but it didn't solve anything. I have absolutelly no idea about where it comes from =(.
我在谷歌看了一下，大多数时候这个问题是由于没有注释“@Transactional”引起的。我试图注释我的方法，但它没有解决任何问题。我完全不知道它来自哪里=（。
Here's the code of my test:
这是我的测试代码：
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations="/applicationContext.xml")
public class BaseTest {
public BaseTest() {
}
@Before
public void setUp() throws IOException {
Dataset.loadDatabase();
}
@Test
public void load(){}
}
The class DataSet just do some saves in the db to see if it's working.
类 DataSet 只是在数据库中进行一些保存以查看它是否正常工作。

This warning means nothing, you shouldn't worry about it since you don't need to apply any post-processors to the DataSource.
此警告没有任何意义，您不必担心，因为您不需要将任何后处理器应用于DataSource.
Technically it means that some bean post-processor (a transactional one, I guess) depends on your DataSource, therefore the DataSourcemust be fully initialized before initialization of that post-processor, so that the post-processor cannot intercept initialization of the DataSource.
技术上讲，它意味着一些豆后处理器（事务之一，我猜）取决于你的DataSource，所以DataSource必须完全是后处理器的初始化之前进行初始化，这样的后处理器无法拦截初始化DataSource。
You need to worry if you get such a warning about a bean you want to apply post-processors to.
如果您收到有关要应用后处理器的 bean 的警告，您需要担心。
