BeanNotOfRequiredTypeException due to autowired fields

Question

I\'m still new to Spring MVC and while building my test project, I got this message from Tomcat logs:

SEVERE: Exception sending context initialized event to          


        

Answer 1

I also have met the problem when execute unit test

I created a mock service to implement the real service to override some method for easy to test some user case

@Component
public static class FooServiceImplMock extends FooServiceImpl {
    @Override
    protected void bar() {
        // do some specific loginc here 
    }
}

but when execute the test method

@Autowired
private Foo1ServiceImplMock foo1ServiceImplMock;

I got below error

Caused by: org.springframework.beans.factory.BeanNotOfRequiredTypeException: Bean named 'fooServiceImplTest.FooServiceImplMock' is expected to be of type 'com.foo.business.impl.FooServiceImplTest$FooServiceImplMock' but was actually of type 'com.sun.proxy.$Proxy97'

Reason:

There is method in FooServiceImpl used @Cacheable

@Cacheable("eventTypes")

And from javadoc of EnableCaching I know

org.springframework.cache.annotation.EnableCaching 
boolean proxyTargetClass()

Indicate whether subclass-based (CGLIB) proxies are to be created as opposed to standard Java interface-based proxies. The default is false.

So the resolve manner is explicitly to specify use CGLIB in spring application contenxt
