In this example you'll see how to read mapped property value of a bean. We use PropertyUtils.getMappedProperty() method the read the mapped property of the Recording object that consist of Track objects.
package org.kodejava.example.commons.beanutils; import java.util.HashMap; import java.util.HashMap; import java.util.Map; import org.apache.commons.beanutils.PropertyUtils; public class ReadMapProperty { public static void main(String[] args) { Recording recording = new Recording(); recording.setTitle("Please Please Me"); Track track1 = new Track(); track1.setTitle("I Saw Her Standing There"); Track track2 = new Track(); track2.setTitle("Misery"); Map tracks = new HashMap(); tracks.put("Track One", track1); tracks.put("Track Two", track2); recording.setMapTracks(tracks); try { Track track = (Track) PropertyUtils.getMappedProperty(recording, "mapTracks(Track One)"); System.out.println("track.getTitle() = " + track.getTitle()); } catch (Exception e) { e.printStackTrace(); } } } package org.kodejava.example.commons.beanutils; import java.util.ArrayList; import java.util.HashMap; import java.util.List; import java.util.Map; public class Recording { private Integer id; private String title; private Map mapTracks = new HashMap(); public Integer getId() { return id; } public void setId(Integer id) { this.id = id; } public String getTitle() { return title; } public void setTitle(String title) { this.title = title; } public Map getMapTracks() { return mapTracks; } public void setMapTracks(Map mapTracks) { this.mapTracks = mapTracks; } } |
And here is the result of our program.
track.getTitle() = I Saw Her Standing There
