Inject Java Collection in Spring

<list> : This helps in wiring i.e. injecting a list of values, allowing duplicates.

<set> : This helps in wiring a set of values but without any duplicates.

<map> : This can be used to inject a collection of name-value pairs where name and value can be of any type.

<props> : This can be used to inject a collection of name-value pairs where the name and value are both Strings.
