Spring Bean Injection Failing Due To Proxy

Question

Spring Version: 3.2.4.RELEASE and 3.2.9.RELEASE

Mockito Version: 1.8.5

I\'ve been trying to introduce H2 tests to an old pr

Alright, once I realised that the class was being proxied due to the @Transactional annotation, the solution to the problem became clearer. What I needed to do was unwrap the proxy, and set the mocked object directly on that:

So in my AbstractIntegrationTest:

/**
 * Checks if the given object is a proxy, and unwraps it if it is.
 *
 * @param bean The object to check
 * @return The unwrapped object that was proxied, else the object
 * @throws Exception
 */
public final Object unwrapProxy(Object bean) throws Exception {
    if (AopUtils.isAopProxy(bean) && bean instanceof Advised) {
        Advised advised = (Advised) bean;
        bean = advised.getTargetSource().getTarget();
    }
    return bean;
}

Then in my @Before:

@Mock
private ProcessHelper processHelper;

@Before
public void setUp() throws Exception {
    MockitoAnnotations.initMocks(this);

    IXMLBatchProcessor iXMLBatchProcessor = (IXMLBatchProcessor) unwrapProxy(xmlProcessor);
    ReflectionTestUtils.setField(iXMLBatchProcessor , "processHelper", processHelper);
}

This left all the @Autowired classes intact, while injecting the correct mocked object.
