Problems with prototype scope: Same bean!

[philion]

I am trying to use the prototype scope in Spring 2.0.5 to create unique beans, but I keep getting the same bean.

I have reduced it to the simplest code I can to repro the problem:

TestBean.java:

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class TestBean {
    private final  String val;
    private String prop;
    public TestBean() { this.val = "default"; }
    public TestBean(String value) { this.val = value; }
    public void setSomeProperty(String value) { this.prop = value; }
    public String toString() { return "[" + System.identityHashCode(this) + "]"; }
    
    public static void main(String[] args) {
        ApplicationContext context = new ClassPathXmlApplicationContext("classpath:prototype-beans.xml");
        
        TestBean bean1 = (TestBean) context.getBean("test");
        TestBean bean2 = (TestBean) context.getBean("test");
        
        int id1 = System.identityHashCode(bean1);
        int id2 = System.identityHashCode(bean2);
        
        if (id1 == id2) {
            System.out.println("Objects are the same: " + bean1 + " == " + bean2);
        }
        else {
            System.out.println("Objects are different: " + bean1 + " != " + bean2);
        }
    }
}

prototype-beans.xml:

<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN 2.0//EN" "http://www.springframework.org/dtd/spring-beans-2.0.dtd">

<beans>
    <bean id="test" class="TestBean" scope="prototype"/> 
</beans>

Whenever I run this I get something like

Objects are the same: [2268884] == [2268884]

Guess, you have 2 your prototypes-beans.xml twice in the classpath - once with prototype and once without.

I have copied your sample as is, without any modifications and it works as it should

I have tested against several Spring versions.

This turns out to be a classpath problem: There was an old version of Spring that was being picked up, which ignored the scope attribute (I assume).

How old? 1.x?
