List,Set,Map,Properties的Spring注入实例

定义接口：

package Bean.collections;
public interface Person {
	public void useAxe();
}

package Bean.collections;
public interface Axe {
	public String chop();
}

定义实现类：

package Bean.collections;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.HashSet;
import java.util.List;
import java.util.Map;
import java.util.Properties;
import java.util.Set;

import Bean.collections.Person;

public class Chinese implements Person {
	private List schools = new ArrayList();
	private Map scores = new HashMap();
	private Properties health = new Properties();
	private Set axes = new HashSet();

	public Set getAxes() {
		return axes;
	}

	public void setAxes(Set axes) {
		this.axes = axes;
	}

	public Properties getHealth() {
		return health;
	}

	public void setHealth(Properties health) {
		this.health = health;
	}

	public List getSchools() {
		return schools;
	}

	public void setSchools(List schools) {
		this.schools = schools;
	}

	public Map getScores() {
		return scores;
	}

	public void setScores(Map scores) {
		this.scores = scores;
	}

	public void useAxe() {
		System.out.println("List --> " + schools);
		System.out.println("Map --> " + scores);
		System.out.println("Properties --> " + axes);
		System.out.println("Set --> " + health);
	}

}

package Bean.collections;

public class WoodAxe implements Axe {
	public WoodAxe(String arg)
	{
		System.out.println("收到:"+arg);
	}

	public String chop() {
		return "这是一把木头斧子";

	}

	public String toString() {
		// TODO Auto-generated method stub
		return "重写toString";
	}
}

package Bean.collections;

public class SteelAxe implements Axe {

    public String chop() {
        return "这是一把铁斧子";

    }
    
    public String toString(){
    	return "重写toString";
    }

}

		<property name="axes">
			<set>
				<value>字符串斧子</value>
        <!-- 用嵌套bean定义属性 -->
				<bean class="Bean.collections.WoodAxe" >
					<constructor-arg index="0">
						<value>Hello,Spring!</value>
					</constructor-arg>
				</bean>
        <!-- 引用bean作为属性 -->
				<ref local="steelaxe" />
			</set>
		</property>
	</bean>
	<bean id="steelaxe" class="Bean.collections.SteelAxe"></bean>
</beans>

运行结果:
收到:Hello,Spring!
List --> [小学, 中学, 大学]
Map --> {数学=88, 语文=99}
Properties --> [字符串斧子, 重写toString, 重写toString]
Set --> {血压=正常, 身高=178}
