问题
Since I have to mock a static method, I am using Power Mock to test my application.
My application uses *Camel 2.1*2.
I define routes in XML that is read by camel-spring context.
There were no issues when Junit alone was used for testing.
While using power mock, I get the error listed at the end of the post.
I have also listed the XML used.
Camel is unable to recognize any of its tags when power mock is used.
I wonder whether the byte-level manipulation done by power mock to mock static methods interferes with camel engine in some way. Let me know what could possibly be wrong.
PS:
The problem disappears if I do not use power mock.

回答1:
When you have these JAXB binding errors with spring then in the past it has been troubles with JAXB version. Can you check the classpath if you have JAXB 2.1 or 2.2. Sometimes the JAXB that comes witht the JDK is too old and buggy, and you may need to have JAXB added to your classpath.
Another idea could be that the error says it does not understand the local namespace. You can try using a prefix, eg such as camel in the XML top, and use
<camel:camelContext>
instead.
回答2:
I got this to work as follows :
@RunWith(PowerMockRunner.class)
@PowerMockIgnore({"org.xml.*", "javax.xml.*", "org.springframework.*","org.apache.commons.logging.*","org.w3c.*","javax.management.*"})
The list of packages in the @PowerMockIgnore annotation was found by trial and error and I have pretty much no idea what I have done, but my unit test now runs and produces the same results as when I didn't use the @RunWith annotation.
