Spring Instance Factory not working - spring

Question

I started learning spring recently and doing a simple demo of Instance factory but getting error.
Java Bean:
package beans;
public class Apache implements Bike
{
#Override
public void getSpeed()
{
System.out.println("160 KMPH");
}
}
Interface:
package beans;
public interface Bike
{
public void getSpeed();
}
Factory:
package beans;
public class BikeFactory
{
public String bikename;
public void setBikename(String bikename) {
this.bikename = bikename;
}
public Bike getInstance() throws Exception
{
Bike bike = (Bike) Class.forName("bikename").newInstance();
return bike;
}
}
Spring config
<?xml version = "1.0" encoding = "UTF-8"?>
<beans xmlns = "http://www.springframework.org/schema/beans"
xmlns:xsi = "http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation = "http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">
<bean id="bf" class="beans.BikeFactory">
<property name="bikename" value="beans.Apache"></property>
</bean>
<bean id="a" factory-bean="bf" factory-method="getInstance"></bean>
</beans>
When I run the code by getting Bike Object from context, I get below error:
Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'a' defined in class path resource [resources/spring-config.xml]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [beans.Bike]: Factory method 'getInstance' threw exception; nested exception is java.lang.ClassNotFoundException: bikename

Am I missing something here? Please help

Answer 1

Your factory method is incorrect. I guess you want to create instance by class name which you autowire by spring, so you don't need double quotes here:
public Bike getInstance() throws Exception {
Bike bike = (Bike) Class.forName(bikename).newInstance();
return bike;
}
Try to change "bikename" to bikename
