org.springframework.beans.factory.CannotLoadBeanClassException

Question

I found a simple problem and ask for help. There are the exception message: Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.CannotLoadBeanClassException: Cannot find class [factory] for bean with name 'us' defined in class path resource [beans.xml]; nested exception is java.lang.ClassNotFoundException: factory

here is interface: package net.runze.spr1.factory;

public interface Person {
    public void testBeing();
}

here is class cn

package net.runze.spr1.factory;

public class CN implements Person {

    @Override
    public void testBeing() {
        System.out.println("china");
    }

}

here is class us:

package net.runze.spr1.factory;

public class US implements Person {

    @Override
    public void testBeing() {
        System.out.println("lalalala US");
    }

}

here is the factory:

package net.runze.spr1.factory;

public class PersonFactory {
    public Person getPerson(String arg) {
        if ("cn".equalsIgnoreCase(arg)) {
             return new CN();
        } else {
             return new US();
        }
    }
}

here is my xml

<bean id="factory" class="net.runze.spr1.factory.PersonFactory"/>

<bean id="cn" 
        factory-bean="factory" 
        factory-method="getPerson">
    <constructor-arg value="cn"></constructor-arg>
</bean>

<bean id="us" 
        class="factory" 
        factory-method="getPerson">
    <constructor-arg value="us"></constructor-arg>
</bean>

here is my test class:

@Test
public void instanceFactorytest1() {
    ApplicationContext context = new ClassPathXmlApplicationContext("beans.xml");

    Person b1 = context.getBean("cn", US.class);
    Person b2 = context.getBean("us", US.class);

    b1.testBeing();
    b2.testBeing();
}

Thank you very much

Answer 1

now i know. really silly~~ i configed it wrong in the xml file

<bean id="us"...> this should be "factory-bean" not class.
