bean class instantiation in spring for a class without default constructor

Question

I am using a third party library class XYZ as an argument in my model. XYZ does not have a default constructor. So spring is not able to create bean for it giving error message

Answer 1

You can define it in the XML file as a spring bean passing all necessary parameters to instantiate it.

sample:

<bean id="xyz" class="com.a.b.Xyz" >
    <constructor-arg index="0" ref="anotherBean"/>
    <constructor-arg index="1" value="12"/> 
</bean>

Answer 2

You'll need to provide <constructor-arg> elements in your application context config file, as described in the documentation.
