All Implemented Interfaces:

junit.framework.Test

public class TestRecursiveConstruction

extends junit.framework.TestCase

A unit test to check validity of recursive constructor injection.

One of the test demonstrates that recursive constructor injection with cyclic dependencies is impossible with Java SDK circa 2004 / 2005!!!

The other test demonstrates how to unravel the former cyclic dependency in Bridgetown. Use property injection for one of the beans instead of constructor injection. In other words this is a work around!

testRecursive1

public void testRecursive1()

Test construction injection where we have two beans that both reference each other. Can the assembly factory work out how to initialise them successfully?

NB: For the current default implementation AbstractServiceAssembler cannot be successfully resolve this case. Therefore the method checks for a thrown RecursiveDependencyException and then exits normally.

testRecursive2

public void testRecursive2()

Test construction injection where we have two beans that both reference each other. Can the assembly factory work out how to initialise them successfully?

In this case we uses a work around either method injection or setter injection after construction.
