Description

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??
