   <bean id="test" class="com.Test">
        <constructor-arg>
            <list>
                <value>aa</value>
                <value>bb</value>
                <value>cc</value>
            </list>
        </constructor-arg>
    </bean>
</beans>

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?

Answer 1

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.
