How do I get the underlying type of a proxy object in java?

Question

I\'d like to access the classname of the underlying class which is an instance of java.lang.reflect.Proxy.

Is this possible?

Answer 1

You can use the following code for retrieve the info (ArrayUtils is from Apache commons lang) about invocation handler and the interfaces of the current proxy:

String.format("[ProxyInvocationHandler: %s, Interfaces: %s]", 
     Proxy.getInvocationHandler(proxy).getClass().getSimpleName(), 
     ArrayUtils.toString(proxy.getClass().getInterfaces()));

Example result:

[ProxyInvocationHandler: ExecuteProxyChain, Interfaces: {interface com.example.api.CustomerApi}]}
