Initializing bean with (derived) commandline arguments

[dkcvan]

Hi,

I'm new at Spring, and I am currently refactoring a legacy standalone app, introducing Spring. The app uses some commandline arguments, for example the url of the jdbc datasource to use. So my question is: how van I initialize a Spring managed bean with commandline arguments ? Any help is appreciated.

Thx.

AFAIK, Spring doesn't contain any cmd line parser and your code probably already contains such functionality. You can either initialize the bean yourself with the given values (but this doesn't uses Spring IOC) or write a beanPostProcessor that access the command-line attributes and finishes the bean initialization.
A good example is org.springframework.beans.factory.config.PropertyP laceholderConfigurer
