一、注入简单属性
package soundsystem.properties;
import org.springframework.beans.factory.annotation.Autowired; import soundsystem.CompactDisc;
import soundsystem.MediaPlayer; public class CDPlayer implements MediaPlayer {
private CompactDisc compactDisc; @Autowired
public void setCompactDisc(CompactDisc compactDisc) {
this.compactDisc = compactDisc;
} public void play() {
compactDisc.play();
} }
1.<property>
<bean id="cdPlayer"
class="soundsystem.CDPlayer">
<property name="compactDisc" ref="compactDisc" />
</bean>
2.p-namespace(p表示property)
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:p="http://www.springframework.org/schema/p"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd"> <bean id="compactDisc" class="soundsystem.BlankDisc">
<constructor-arg value="Sgt. Pepper's Lonely Hearts Club Band" />
<constructor-arg value="The Beatles" />
</bean> <bean id="cdPlayer" class="soundsystem.properties.CDPlayer"
p:compactDisc-ref="compactDisc" /> </beans>
二、注入集合属性
package soundsystem.properties;
import java.util.List;
import soundsystem.CompactDisc;
public class BlankDisc implements CompactDisc {
private String title;
private String artist;
private List<String> tracks;
public void setTitle(String title) {
this.title = title;
}
public void setArtist(String artist) {
this.artist = artist;
}
public void setTracks(List<String> tracks) {
this.tracks = tracks;
}
public void play() {
System.out.println("Playing " + title + " by " + artist);
for (String track : tracks) {
System.out.println("-Track: " + track);
}
}
}
