Can I set null as the default value for a @Value in Spring?

Question

I\'m currently using the @Value Spring 3.1.x annotation like this:

@Value(\"${stuff.value:}\")
private String value;

This puts an empty Str

In case you need to inject an empty (0 length) "" string as @Value default - use SPEL (spring expression language) as follows:

@Value("${index.suffix:#{''}}") 
private String indexSuffix;

#{''} just gets you an empty string as injected @Value's default.
