since args is an array of Object you can use :

<bean name="myBean" class="MyClass"> <constructor-arg> <list> <value>111</value> <value>222</value> <value>333</value> <value>444</value> </list> </constructor-arg> </bean>

If your parameter was of type Class<?>, then all you would need is to provide the fully qualified class name

<constructor-arg index="0">java.lang.String</constructor-arg>

But since you have a varargs, you need to add an <array> with values

<constructor-arg index="0">
    <array>
        <value>
            java.lang.String
        </value>
    </array>
</constructor-arg>
