RE: [Springframework-developer] Bean order in applicationContext.xml changed? How to force order.

[<jue...@we...>]

Jon,

You should never rely on bean ordering in a context definition file. =
Bean definitions are internally stored in a HashMap; the original order =
will *not* be preserved. Bean factory internals have been significantly =
reworked in the last couple of months, so there might indeed be a change =
in the actual loading order.

Note that Spring will automatically initialize dependent beans first. So =
if you express dependencies via <ref> tags, the referenced beans will =
get initialized first (recursively). If you have non-obvious =
dependencies without direct references, you can declare "depends-on" =
attributes at the <bean> level: The beans whose names are specified =
there will get initialized before the respective bean then.

In your case, you could declare =
depends-on=3D"myController1,myController2,..." on the <bean> definition =
of your master controller. The actual definition order of your =
controllers in the XML file doesn't matter, so you're free to place this =
master controller definition anywhere.

Subject: [Springframework-developer] Bean order in
applicationContext.xml changed? How to force order.


Hi,

I used to use M2, now M4.

I suspect that something has changed between the two versions, with
respect to the order in which beans that are declared in
applicationContext.xml, are instantiated.  Unfortunately I can't
immediately check this as rolling back my changes are going to take a
few hours.  Can anybody confirm that this has taken place?  Previously,
I believe the syntactic order played a role (subject to dependency
resolution).

I have a nasty situation in which as my controllers are loaded, they
register security  information about themselves with a class.  A
"master" controller that needs to be loaded last, uses this registered
information in its configuration.  In M2 I placed this class last in
the dispatcher-servlet.xml, and it got instantiated last. =20

Is there anyway that I can specify this dependency, or change some
Spring component to honour syntactic order as much as possible?

Thanks
Jon
