一、注入简单属性
1 package soundsystem.properties; 2 import org.springframework.beans.factory.annotation.Autowired; 3 4 import soundsystem.CompactDisc; 5 import soundsystem.MediaPlayer; 6 7 public class CDPlayer implements MediaPlayer { 8 private CompactDisc compactDisc; 9 10 @Autowired 11 public void setCompactDisc(CompactDisc compactDisc) { 12 this.compactDisc = compactDisc; 13 } 14 15 public void play() { 16 compactDisc.play(); 17 } 18 19 }
1.<property>
<bean id="cdPlayer"
class="soundsystem.CDPlayer">
<property name="compactDisc" ref="compactDisc" />
</bean>
2.p-namespace(p表示property)
1 <?xml version="1.0" encoding="UTF-8"?> 2 <beans xmlns="http://www.springframework.org/schema/beans" 3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 4 xmlns:p="http://www.springframework.org/schema/p" 5 xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd"> 6 7 <bean id="compactDisc" class="soundsystem.BlankDisc"> 8 <constructor-arg value="Sgt.

二、注入集合属性
1 package soundsystem.properties; 2 3 import java.util.List; 4 5 import soundsystem.CompactDisc; 6 7 public class BlankDisc implements CompactDisc { 8 9 private String title; 10 private String artist; 11 private List<String> tracks; 12 13 public void setTitle(String title) { 14 this.title = title; 15 } 16 17 public void setArtist(String artist) { 18 this.artist = artist; 19 } 20 21 public void setTracks(List<String> tracks) { 22 this.tracks = tracks; 23 } 24 25 public void play() { 26 System.out.println("Playing " + title + " by " + artist); 27 for (String track : tracks) { 28 System.out.println("-Track: " + track); 29 } 30 } 31 32 }
