How can you inject Java Collection in Spring?

Answer»

Spring offers four types of collection configuration elements which are as follows −

  • <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.
