List,Set,Map,Properties的Spring注入实例

定义接口：

package Bean.collections;

public interface Person ... {
publicvoiduseAxe();
}
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 ... {
privateListschools=newArrayList();
privateMapscores=newHashMap();
privatePropertieshealth=newProperties();
privateSetaxes=newHashSet();
publicSetgetAxes()...{
returnaxes;
}
publicvoidsetAxes(Setaxes)...{
this.axes=axes;
}
publicPropertiesgetHealth()...{
returnhealth;
}
publicvoidsetHealth(Propertieshealth)...{
this.health=health;
}
publicListgetSchools()...{
returnschools;
}
publicvoidsetSchools(Listschools)...{
this.schools=schools;
}
publicMapgetScores()...{
returnscores;
}
publicvoidsetScores(Mapscores)...{
this.scores=scores;
}
publicvoiduseAxe()...{
System.out.println(schools);
System.out.println(scores);
System.out.println(axes);
System.out.println(health);
}

}

package Bean.collections;

public class SteelAxe implements Axe ... {

publicStringchop()...{
return"这是一把铁斧子";

}

}


package Bean.collections;

public class WoodAxe implements Axe ... {

publicStringchop()...{
return"这是一把木头斧子";

}

}

spring配置文件：

<! DOCTYPEbeansPUBLIC"-//SPRING//DTDBEAN//EN""http://www.springframework.org/dtd/spring-beans.dtd" >

<!-- 用嵌套bean定义属性 -->

<!-- 引用bean作为属性 -->
< ref local ="steelaxe" />
</ set >
</ property >

< bean id ="steelaxe" class ="Bean.collections.SteelAxe" ></ bean >

测试代码：

public static void main(String[]args) throws Exception ... {

Stringpath=newTest().getClass().getResource("/").getPath();
Stringrealpath=path.substring(1,path.length());
ApplicationContextcontext=newFileSystemXmlApplicationContext(realpath+"/collection.xml");


Personperson1=(Person)context.getBean("chinese");
person1.useAxe();


}

运行结果“

[小学, 中学, 大学]
{数学=88, 语文=99}
[字符串斧子, Bean.collections.WoodAxe@1506dc4, Bean.collections.SteelAxe@1126b07]
{血压=正常, 身高=178}
