Update database settings in properties file in Spring

Answer 1

You need to refresh your Application context and get the bean DriverManagerDataSource again in order to reflect the changes written to propertie files.

context.refresh();
DriverManagerDataSource databaseSource = (DriverManagerDataSource)context.getBean("dataSource");
databaseSource.getUsername();

Tip for getting File object of your resource:

    URI a = getClass().getResource("/com/smartcall/bundle/database.properties").toURI();
    File file = new File(a);

You will not need to decode the path, i.e. replacing %20 with " ". Referrence
