> I want to convert a bean class to a map (key=the name of the member,value=the value of
the member).
> I'm using the method BeanUtils.describe(beanClass);
> (I'm using commons-beanutils 1.8.3, jdk 1.6.0_20, on commons-beanutils 1.5 it works)
> The problem is that the return value is incorrect, (the map contain only the first item
from the array),
> the code:
> public class Demo { 
>         private ArrayList<String> myList = new ArrayList<String>(); 
>         public Demo() { 
>             myList.add("first_value"); 
>             myList.add("second_value"); 
>         } 
>  
>         public ArrayList<String> getMyList() { 
>             return myList; 
>         } 
>  
>         public void setMyList(ArrayList<String> myList) { 
>             this.myList = myList; 
>         } 
>  
>         public static void main(String[] args) { 
>             Demo myBean = new Demo(); 
>             try { 
>                 Map describe = BeanUtils.describe(myBean); 
>                 Iterator it = describe.entrySet().iterator(); 
>                 while (it.hasNext()) { 
>                     Map.Entry pairs = (Map.Entry) it.next(); 
>                     System.out.println(String.format("key=%s,value=%s", (String) pairs.getKey(),
(String) pairs.getValue())); 
>  
>                 } 
>             } catch (Exception e) { 
>                 e.printStackTrace(); 
>             } 
>         } 
>     } 
>  •The expected output:
>  
> key=myList,value=[first_value,second_value]
> key=class,value=class $Demo
>  •But the real output is:
>  
> key=myList,value=[first_value]
> key=class,value=class $Demo
> As you can see the array contains two values but the output(and the map) contains only
one,why??
