ThreadLocalTargetSource help

[wsshek]

Hi all,

I would like to destroy / cleanup a bean that has its target set as a
ThreadLocalTargetSource object. I am using ApplicationContext to create the
mentioned bean. What's the best way to cleanup only the ThreadLocal bean?

I could call ApplicationContext.destroy() but it would close the context and
destroy all singletons. Is it approximate to get a reference to
ThreadLocalTargetSource and cast it to DisposableBean and invoke destroy()
directly? If so, how do I do it?

Here's my config:

    <bean id="sessionManager"
class="org.springframework.aop.framework.ProxyFactoryBean">
        <property name="proxyInterfaces" value="foo.SessionManager"/>
        <property name="targetSource">
            <bean
class="org.springframework.aop.target.ThreadLocalTargetSource">
                <property name="targetBeanName" value="sessionManagerImpl"/>
            </bean>
        </property>
    </bean>

    <bean id="sessionManagerImpl" class="foo.SessionManagerImpl"
singleton="false"/>

On another note, I was checking the ThreadLocalTargetSource
source and the way it's clearing the ThreadLocal variable is like this:

	public void destroy() {
                        .........
		this.targetSet.clear();
		
		// clear ThreadLocal
		this.targetInThread = null;
	}

Shouldn't we call this.targetInThread.set(null) instead?


Thanks for your help!

If you need control over a ThreadLocal variable I would advise to not use ThreadLocalTargetSource, but to manage the variable yourself as ThreadLocal. So you are able to change its contents as you see it fits.
