spring复杂属性的配置

package  com.open.bean;
import  java.util.List;
import  java.util.Map;
import  java.util.Properties;
public   class  BeanSet  {
     private  String[] str1;
     private  String[] str2;
     private  List lst;
     private  Map map;
     private  Properties props;
     private  ChildBean[] child;
    // 省略set,get方法
}

package  com.open.bean;
public   class  ChildBean {}

配置文件

< beans >
< bean  id ="bs"  class ="com.open.bean.BeanSet" >
         < property  name ="str1" >
             < list >
                 < value > value1 </ value >
                 < value > value2 </ value >
             </ list >
         </ property >
         < property  name ="str2" >
             < value > value3,value4 </ value >
         </ property >
         < property  name ="lst" >
             < list >
                 < value > value5 </ value >
                 < ref  bean ="cc1" />
             </ list >
         </ property >
         < property  name ="map" >
             < map >
                 < entry  key ="key1" >
                     < value > xxx </ value >
                 </ entry >
                 < entry  key ="key2" >
                     < ref  bean ="cc1" />
                 </ entry >
             </ map >
         </ property >
         < property  name ="props" >
             < props >
                 < prop  key ="key1" > xxx </ prop >
                 < prop  key ="key2" > yyy </ prop >
             </ props >
         </ property >
         < property  name ="child" >
             < list >
                 < ref  bean ="cc1" />
                 < ref  bean ="cc2" />
             </ list >
         </ property >
     </ bean >
     < bean  id ="cc1"  class ="com.open.bean.ChildBean" />
     < bean  id ="cc2"  class ="com.open.bean.ChildBean" />
</ beans >

测试代码

package  com.open.bean;
import  java.util.List;
import  java.util.Map;
import  java.util.Properties;
import  org.springframework.context.support.ClassPathXmlApplicationContext;
public   class  Test1  {
    public static void main(String[] args) {
        ClassPathXmlApplicationContext cx=
            new ClassPathXmlApplicationContext("bean.xml");
        BeanSet bs=(BeanSet)cx.getBean("bs");
        String[] str1=bs.getStr1();
        String[] str2=bs.getStr1();
        List lst=bs.getLst();
        Map map=bs.getMap();
        Properties props=bs.getProps();
        ChildBean[] cb=bs.getChild();
        System.out.println("str1="+"["+str1[0]+","+str1[1]+"]");
        System.out.println("str2="+"["+str2[0]+","+str2[1]+"]");
        System.out.println("lst="+lst);
        System.out.println("map="+map);
        System.out.println("props="+props);
        System.out.println("cb="+"["+cb[0]+","+cb[1]+"]");
    }
}

输出结果

str1 = [value1,value2]
str2 = [value1,value2]
lst = [value5, com.open.bean.ChildBean@1df073d]
map = {key1=xxx, key2=com.open.bean.ChildBean@1df073d}
props = {key2=yyy, key1=xxx}
cb = [com.open.bean.ChildBean@1df073d,com.open.bean.ChildBean@1546e25]
