Question

I want to call a method after creating the bean using spring, for example I create Factory and schema but I want to call the same method of Factory before creating a schema bean

 <!-- schemaFactory-->
    <bean id="schemaFact" class="javax.xml.validation.SchemaFactory"
        factory-method="newInstance">
        <constructor-arg value="http://www.w3.org/2001/XMLSchema" />
    </bean>

<!-- schema -->
    <bean id="schema" class="javax.xml.validation.Schema"
        factory-bean="schemaFact" factory-method="newSchema">
        <constructor-arg value="3DSecure.xsd" />
    </bean>

If you are using Spring 3.0/3.1 you can take advantage of Java configuration:

@Configuration
class Config {

    @Bean
    public SchemaFactory schemaFact() throws SAXNotSupportedException, SAXNotRecognizedException {
        final SchemaFactory schemaFactory = SchemaFactory.newInstance("http://www.w3.org/2001/XMLSchema");
        schemaFactory.setFeature("apache.org/xml/features/validation/schema-full-checking", false);
        return schemaFactory;
    }


    @Bean
    public Schema schema() throws SAXException {
        return schemaFact().newSchema(new File("3DSecure.xsd"));
    }
}

But which method on SchemaFactory do you want to call? Seems like all of them are either getters or setters, so you can use normal XML injection… Alternatively create your own FactoryBean:

class SchemaFactoryFactoryBean implements FactoryBean<SchemaFactory> {

    @Override
    public SchemaFactory getObject() throws Exception
    {
        final SchemaFactory schemaFactory = SchemaFactory.newInstance("http://www.w3.org/2001/XMLSchema");
        schemaFactory.setFeature("apache.org/xml/features/validation/schema-full-checking", false);
        return schemaFactory;
    }

    @Override
    public Class<?> getObjectType()
    {
        return SchemaFactory.class;
    }

    @Override
    public boolean isSingleton()
    {
        return true;
    }
}

And use it like this (no factory-method needed):

<bean id="schemaFact" class="SchemaFactoryFactoryBean"/>
