Subject: [Springframework-developer] Hot updating of bean properties = (spring-dev-list: to exclusive) =20 I had an idea and wanted to see if anyone has persued it. =20 So you know how the ProperyPlaceholderConfigurer allows you to = externalize properties using ant style notation ${some.prop} in bean = definitions? =20 What if you could change those values at runtime and have the = Configurer hot update the property on the bean with the latest value? =20 Obviously the configurer would need to keep track of the beans created = from the bean definitions it first updates, but I don't think this is = something that would be too hard to do. =20 Also, I realize that not all beans are amenable to having their = properties updated. So although a boolean attribute might be easily = switched, updating say the URL on a JDBC connection would be more = complicated since it might imply that all connections should be flushed, = something the standard datasource might not do (or maybe it throws an = IllegalStateException). =20 At anyrate, has anyone tinkered around with an idea like this? =20 Thanks, =20 Bryant -------------------------------------------------------------------------= ----- = -------------------------------------------------------------------------= This SF.net email is sponsored by: Microsoft Defy all challenges.
