list - How to iterate over a property file in Spring xml -

-

i have property file details2.txt , filled values :

list.value=34 list.value=35 list.value=38 list.value=45 list.value=23

now want iterate in spring xml , unable 

xml code (parts only) :   <context:property-placeholder location="details2.txt" />      <constructor-arg>        <list>            <value>${list.value}</value>        </list>      </constructor-arg>

this gives last value in property file

a property file translated properties object, in turn subclass of hashtable, contains one-to-one mapping key value. means properties object indeed contain last value (since previous ones have been overwritten).

one common way of handing problem in property files add suffix keys:

list.value.1=34 list.value.2=35 list.value.3=36 list.value.4=37

but doesn't when using spring, since each property key need explicitly specified in xml file (and i'm assuming don't know exact number of items).

your best bet specify items comma-separated list:

list.values=34,35,36,37

and use configuration trick, such described here or here.
