Spring: Inject static member (System.in) via constructor
- by Julian Lettner
I wrote some sort of console client for a simple application.
To be more flexible, I thought it would be nice to only depend on java.io.Input-/OutputStream, instead of accessing System.in/out directly.
I renamed the class ConsoleClient to StreamClient, added setters and made sure that the instance fields are used instead of System.in/out.
At the moment my client code looks like this:
ApplicationContext appCtx = new ClassPathXmlApplicationContext("...");
StreamClient cc = (StreamClient) appCtx.getBean("streamClient");
cc.setInputStream(System.in);
cc.setOutputStream(System.out);
cc.run(); // start client
Question:
Is there a way to move lines 3 and 4 into the Spring configuration (preferably constructor injection)?
Thanks for your time.
