AspectJ, AJDT and Spring-AOP - exception initializing

[vanhre]

Hi,
Looking at these forums,scanning the internet for a problem with my test application
Environment
Spring 2.5.6,Eclipse 3.5 + AJDT 2.0 + AspectJ 1.6.5, Junit 4.4

Aspects
Aspect using Spring-AOP annotation to enhance my basic DAO's

@Aspect
public class DAOPropertySupportAdvice implements DAOPropertySupport {
.....
@Around("be.titan.hesperus.aspects.SystemArchitecture.DAOgetNew() && @target(be.titan.hesperus.annotations.DynamicPropertySupport)")
	public Object addNewDynamicProperties(ProceedingJoinPoint pjp)
			throws Throwable {
...
@Around("be.titan.hesperus.aspects.SystemArchitecture.DAOgetById() && @target(be.titan.hesperus.annotations.DynamicPropertySupport)")
	public Object addDynamicPropertiesById(ProceedingJoinPoint pjp)
			throws Throwable {
...

MockDAO
Test DAO has it's methods advised by previous Aspect. (verified in AJDT)

@DynamicPropertySupport
public class MockDAO implements GenericDAO<MockPO, String> {
...	
	public MockPO getNew() {		
            return new MockPO();
...

MockPO in above code is enhanced by AspectJ CTW. (=OK)

Unit test

I wrote a unit test to verify the weaving in the DAO class

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "classpath:spring/testApplicationContext.xml" })
public class MockTest {
	@Autowired(required = true)
	protected MockDAO mockDAO;

	@Test
	public void testCreateMockWithAdvice() throws Exception {
		MockPO mockPO = new MockPO();
		Assert.assertTrue(mockPO instanceof PropertyContainer);
	}

	@Test
	public void testCreateMockWithProperties() throws Exception {
		MockPO mockPO = mockDAO.getNew();		
		Assert.assertTrue(((PropertyContainer) mockPO).existProperty("mockLimit"));
	}
}

applicationcontext
And this is the xml-file used in the unittest

.....
	<aop:aspectj-autoproxy>
		<aop:include name="PropertySupportAdvice" />
	</aop:aspectj-autoproxy>

	<!-- aspect for handling dynamic properties by DAO classes -->
	<bean id="PropertySupportAdvice"
		class="be.titan.hesperus.general.persistence.dynamicproperty.DAOPropertySupportAdvice">
		<constructor-arg
			type="be.titan.hesperus.general.persistence.dynamicproperty.PropertyHandler">
			<bean id="supportPropertyHandler"
				class="be.titan.hesperus.general.persistence.dynamicproperty.JdbcPropertyHandler">
				<constructor-arg>
					<ref bean="dataSource" />
				</constructor-arg>
			</bean>
		</constructor-arg>

		<property name="propertyMapperMap">
			<util:map>
				<entry key="be.titan.hesperus.datalayer.organizationmanager.PartyInfo"
					value="partyPropertyMapper" />
				<entry key="be.titan.hesperus.general.persistence.MockPO"
					value="mockPropertyMapper" />
			</util:map>
		</property>
	</bean>

...

Error
When running the unittest the first test is OK but 2nd one gives the below stacktrace. I'm missing a default constructor which is correct as I need to initialize the PropertySupportAdvice. Anybody have a clue how to solve this?

... and if I switch over to spring LTW (using the -javaagent:spring-agent.jar parameter) I get the an enormous stacktrace but this is the most important part I guess

Unable to continue, this version of AspectJ supports classes built with weaver version 5.0 but the class be.titan.hesperus.general.persistence.MockPO is version 6.0

So, then I came to the conclusion that I wasn't using Spring 2.5.6 but rather 2.5.5. Upgraded. Run my UnitTest and I get :

Jul 12, 2009 12:18:06 AM org.aspectj.weaver.tools.Jdk14Trace error
SEVERE: be/titan/hesperus/general/persistence/MockDAO
org.aspectj.weaver.BCException: malformed org.aspectj.weaver.WeaverState attribute (length:5884)org.aspectj.weaver.BCException: bad kind: 11
when processing type mungers 
when weaving

This is my aop.xml file

<!DOCTYPE aspectj PUBLIC
        "-//AspectJ//DTD//EN" "http://www.eclipse.org/aspectj/dtd/aspectj.dtd">
<aspectj>
    <weaver>
        <!-- only weave classes in our application-specific packages -->
        <include within="be.titan.hesperus.general.persistence.*"/>
    </weaver>
    <aspects>
        <!-- weave in just this aspect -->
        <!-- aspect name="foo.ProfilingAspect"/ -->
        <aspect name="be.titan.hesperus.general.persistence.dynamicproperty.DAOPropertySupportAdvice"/>
        <aspect name="be.titan.hesperus.general.persistence.lifecyclesupport.DAOLifecycleSupportAdvice"/>
    </aspects>
  </aspectj>

It also tries to weave an additional class not mentioned in the aop.xml but I guess this has to do with the @Configurable annotation....

Cheers,

Ok, finally managed it solve it myself. I dropped the idea of LTW and went back to my original solution.
The problem was indeed that AspectJ always uses the default constructor which I didn't have (cought up on my reading on AspectJ). So I dropped the constructor with the arguments and added a new setter operation to the aspect.
In the XML-declaration I added factory-method="aspectOf". A couple of minutes later I had my test running like a charm.

Cheers,

I had exactly the same problem, but in my case I cannot change the constructor, because I was extending some class. In my case addition of aspectjrt dependency (1.6.12) solved the problem (Spring 3.1.2).
