Help me to add a hash map object to Spring application context

[Sarath Koiloth Ramath]

Hi Friends,

I need to add a hash map object programatically to spring application context object.I am a newbie to Spring frame work. For every request I need to compare the key-value pair.if the key is not found i need to update the hashmap with new key-value and then again store it back to applicationContext .Can anyone please help me to solve this.


Thanks

You don't need to "store anything back" to the application context--just add they key/value pair to the hashmap.

thanks for the reply.Then to add the hash map to the spring application context programatically. can you please help me on this...

[David Newton]

Why not just put it in the config file?

[Sarath Koiloth Ramath]

My requirement is like that,I had to add some objects to application context at runtime.

[David Newton]

That's not what you said earlier: your first message indicated you just needed to add objects to a map in the application context. Which is it?

[Sarath Koiloth Ramath]

Sorry for the confusion.But I want to add an hashmap object to the applicationContext at runtime.Also if we update the the hashmap.It has to be reflected in the appicationContext as well...

[David Newton]

Any updates made to a hashmap in the application context are reflected in the hashmap in the application context--because it's the hashmap in the application context.

If I google for "spring +add beans programmatically" I get a lot of hits--the two most useful on the first page (for me) were:

http://stackoverflow.com/questions/974620/programmatically-create-a-spring-context (see the last answer)

I'm not clear on why you'd want or need to do this, though--are you sure it's the best answer?
