This is my current XML.
If only Test
took a List - everything would be fine.
The problem is that Test
takes an array of strings.
How to do it in Spring?
You should use:
<constructor-arg>
<array>
<value>aa</value>
<value>bb</value>
<value>cc</value>
</array>
</constructor-arg>
An array can contain multiple inner bean, ref, collection, or value elements. This configuration element will always result in an array, even when being defined e.g. as a value for a map with value type Object.
Also you can specify a value type which you will be passing:
<array value-type="java.lang.String">
<value>aa</value>
<value>bb</value>
<value>cc</value>
</array>
value-type
The default Java type for nested values. Must be a fully qualified class name.
