Java Reference
In-Depth Information
has a
children
attribute of type
List
, so it's assigned to a list containing
bart
and
lisa
.
I don't want to go through all the tests here, but there are a couple of features that should
be highlighted. For example, you can define beans at different scopes, as shown in the next
listing.
Listing 7.30. Defining beans at different scopes
void testScopes() {
def bb = new BeanBuilder()
bb.beans {
myBean(ScopeTest) { bean ->
bean.scope = "prototype"
}
myBean2(ScopeTest)
}
def ctx = bb.createApplicationContext()
def b1 = ctx.myBean
def b2 = ctx.myBean
assert b1 != b2
b1 = ctx.myBean2
b2 = ctx.myBean2
assertEquals b1, b2
}
By setting the
scope
attribute on
myBean
to
prototype
, retrieving the bean twice res-
ults in separate instances. The scope of
myBean2
is singleton by default, so asking for it
twice results in two references to the same object.
You can also use tags from different Spring namespaces. Earlier in this chapter I created an
aspect using Groovy. The following listing shows a similar case using the
BeanBuilder
.
Listing 7.31. Defining an aspect using
BeanBuilder
void testSpringAOPSupport() {
def bb = new BeanBuilder()
bb.beans {
xmlns aop:"http://www.springframework.org/schema/aop"
