复杂类型注入

对象 ref

​ 数组

?

1 2 3

<array>    <value>/<ref>  </array>

　　

list

?

1 2 3

<list>   <value>/<ref>  </list>

　　

map

?

1 2 3

<map>        <entry key="" value=""/value-ref=""></entry> </map>

　　

properties

?

1 2 3 4 5

<props>     <prop key="">value</prop>   </props>

　　

测试代码：

1)定义一个类，属性是各种复杂类型

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

public class AA {   private int[] arr;   private Drink[] drinkArr;   private List<String> stringList;   private List<Drink> drinkList;   private Map<String,Drink> map;   private Properties properties;           。。。    set和get方法    --    }
