Factory

[jackett_dad]

I want to use spring to implement a factory that takes a parameter in the factory method call. The value of that parameter is dynamically determined at runtime and is not known beforehand. Here is a sample config:

    <bean id="a" class="com.sepaton.sms.s2xmgr.test.A"/>

    <bean id="testValue" class="java.lang.String" factory-bean="a"
          factory-method="getMappedValue">
        <constructor-arg name="key" value=""/>
    </bean>

The class A looks like this:

public class A {
    private Map<String, String> testMap = new HashMap<String, String>();

    public A() {
        testMap.put("1", "Value 1");
        testMap.put("2", "Value 2");
        testMap.put("3", "Value 3");
        testMap.put("4", "Value 4");
    }

    public String getMappedValue(String key) {
        return testMap.get(key);
    }
}

And my test class looks like this:

public class SampleSpringTest {
    public static void main(String[] args) {
        ApplicationContext springContext = new ClassPathXmlApplicationContext("spring/test/sample-spring-config.xml");
        String testValue = (String) springContext.getBean("testValue", "2");
        System.out.println(testValue);
    }
}

So my spring config is supplying a blank for the key value, and of course that returns null. Is there a way I can have spring directly return the keyed value in the getBean method without having to get the factory bean (A in this example) in a separate step?

Every time I ask a question I find my own answer it seems. The solution is to set the scope of my factory bean to prototype.
