New issue 390 by taowen: bindInterceptor in child injector
http://code.google.com/p/google-guice/issues/detail?id=390
@Test
public void test() {
TestObject testObject =
Guice.createInjector().createChildInjector(new AbstractModule() {
protected void configure() {
bindInterceptor(Matchers.any(), Matchers.any(), new
TestMethodInterceptor());
}
}).getInstance(TestObject.class);
testObject.hello();
}
public static class TestObject {
public void hello() {
System.out.println("Hello");
}
}
public static class TestMethodInterceptor implements MethodInterceptor {
public Object invoke(MethodInvocation invocation) throws Throwable {
throw new UnsupportedOperationException();
}
}
the test will println hello, instead of throw
UnsupportedOperationException. I guess the default binding is always fall
back to the parent injector, so the interceptor bind in the child injector
is not picked up. I am not sure this is a issue, or could be fixed. A work
around is to bind(TestObject.class) in the child injector.
