Spring Map Example

In this example you will see how bean is prepared for injecting Map collection type key and its values.

import java.util.Iterator;
import java.util.Map;

public class MapBean {
  private Map<String, Integer> student;
  public void setDetails(Map<String, Integer> student) {
  this.student = student;
  }
  public void showDetails() {
     Iterator it = student.entrySet().iterator();
        while (it.hasNext()) {
            Map.Entry pairs = (Map.Entry)it.next();
            System.out.println(pairs.getKey() + " = " + pairs.getValue());
        }
  }
}

In the config file :

<bean id="mapbean" class="com.xxxx.MapBean">
     <property name="details">
          <map>
               <entry key="Satya" value="101"/>
               <entry key="Rohit" value="102"/>
               <entry key="Aniket" value="103"/>
          </map>
     </property>
</bean>
