Using a dynamic proxy as the command class

[bensorek]

I want to use a dynamic proxy as my controller's command class but i get the following error:

org.springframework.beans.TypeMismatchException: Failed to convert property value of type [$Proxy160] to required type [
java.lang.Class] for property 'commandClass'

The reason I am doing this is because I have 2 interfaces to one implementation class, since I want to use 1 interface when using the class internally and the other when exposing the class in the API. I find that using a dynamic proxy will solve this problem for me.

My spring configuration are as follows:

The definition of the proxy is as follows:

<bean id="jobTarget" class="com.bsd.cg.core.job.JobImpl"/>

    <bean id="job" class="org.springframework.aop.framework.ProxyFactoryBean">
        <property name="proxyInterfaces">
            <value>com.bsd.cg.core.job.Job</value>
        </property>
        <property name="target">
            <ref local="jobTarget"/>
        </property>
    </bean>

and the controller is as follows:

<bean id="submissionController" class="com.bsd.webapp.action.submission.DEXSubmissionController" singleton="false">
        <property name="commandName">
            <value>job</value>
        </property>
        <property name="commandClass">
            <ref bean="job"/>
        </property>
        <property name="formView">
            <value>submission</value>
        </property>
        <property name="successView">
            <value>submission</value>
        </property>
        <property name="sessionForm">
            <value>true</value>
        </property>
        <property name="validators">
            <list>
                <ref local="beanValidator"/>
                <ref local="submissionValidator"/>
            </list>
        </property>
    </bean>

Don't supply the commandClass. The controller will use this setting to construct a new form. You will also need to override createForm and return the proxy.

I would (doesn't mean its correct ) pass in the factory that creates the proxy to the controller, and then on createForm return a new instance from that factory.
