Question

I have a bean factory class as follows:

public class BeanFactory {
public static BeanInterface getInstance(int id) {
    return new Bean(id);
    }
}

I want to use this class in spring container to get the instances of Instrument class, and have added a bean entry in applicationcontext.xml as follows:

<bean id="TestBean" class="com.test.beans.BeanFactory" factory-method="getInstance">
</bean>

But I am not able to find any way through which I can pass id to getInstance factory method.
Is there any way I can pass a parameter to this factory method?

EDIT: Consider the bean factory as scope=”prototype”. I want new instances of TestBean based on the value of ID.

Answer 1

The rules are the same as if it was normal Spring constructor, i.e. you can use <contructor-arg value="..."/>

From documentation

Arguments to the static factory method are supplied via
elements, exactly the same as if a constructor had
actually been used. The type of the class being returned by the
factory method does not have to be of the same type as the class that
contains the static factory method, although in this example it is. An
instance (non-static) factory method would be used in an essentially
identical fashion (aside from the use of the factory-bean attribute
instead of the class attribute), so details will not be discussed
here.
