basic wiring question

[aharvey]

I have a bean that implements ApplicationContextAware and of course provides its own setApplicationContext() setter per the interface definition.

I am using this bean in a JUnit context where AUTOWIRE_BY_NAME is set. I am getting an exception from the Spring container because the object type for ApplicationContext on my bean is not understood.

What do I need to do to avoid this and have Spring ignore this ApplicationContext property when it processes AUTOWIRE_BY_NAME?

Thanks

It would be really useful to see the TestCase, the full stacktrace and the applicationContext.xml. If you code wrap them in [ code] [ /code] tags, it's soooo much easier to use.

Okay here is some sample code to illustrate.

Sample JUnit class

public class MyTestCase extends AbstractDependencyInjectionSpringContextTests{
        private SomeBeanClass myBean = null;
	public MyTestCase()
	{
		setAutowireMode(AUTOWIRE_BY_NAME);
	}	

        public void testSomething()
        {
          // use the bean somehow
        }

        public void setMyBean(SomeBeanClass value)
        {
           myBean = value;
        }
	@Override
	protected String[] getConfigLocations() {
		return new String[] { "classpath:testApplicationContext.xml" };
	}
}

testApplicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
 <bean id="myBean" class="com.SomeBeanClass">
  <!-- boring properties -->
 </bea>
</beans>

SomeBeanClass example

public class SomeBeanClass implements ApplicationContextAware
{
   private ApplicationContext applicationContext = null;
  // property getter/setters and some business logic here


	public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
		this.applicationContext = applicationContext;
	}
}

If you create an interface, SomeBeanInterface and get SomeBeanClass to implement that. Then change the property and the setter in the unit test to use SomeBeanInterface instead. The problem should go away.
