04_Spring_Collection_Injection

Merhaba arkadaşlar, bu yazımda Collections Injection konusunu anlatacağım. 4 adet collection tipinde inject işlemi yapılır. Bunlar:

  • List – <list/>
  • Set – <set/>
  • Map – <map/>
  • Properties – <props/>

Şimdi örnek üzerinden anlatalım:

public class CollectionsClass {
 
      private List<String>myList;
      private Map<Integer, String>myMap;
      private Set<String>mySet;   
     
      public List<String> getMyList() {
         System.out.println("MyList=> "+myList);
          return myList;
      }
      public void setMyList(List<String> myList) {
            this.myList = myList;
      }
      public Map<Integer, String> getMyMap() {
          System.out.println("MyMap=> "+myMap);
          return myMap;
      }
      public void setMyMap(Map<Integer, String> myMap) {
          this.myMap = myMap;
      }
      public Set<String> getMySet() {
         System.out.println("MySet=> "+mySet);
          return mySet;
      }
      public void setMySet(Set<String> mySet) {
          this.mySet = mySet;
      }
}
