More example for proxy support for constructor class with Enhancer ?

[bwzhang2011]

Hi, cglib team. I encountered some problem when make proxy support towards the bean with constructor params. e.g when I want to some proxy usecases towards jedis (framework integration with redis server). here comes my code like this with enhancer:

public T getInstance(T target, Class[] args, Object[] argsValue) {
Enhancer enhancer = new Enhancer();
enhancer.setSuperclass(target.getClass());
enhancer.setCallback(this);
return (T) enhancer.create(args, argsValue);
}

the target is jedis like this:
public class Jedis extends BinaryJedis implements JedisCommands, MultiKeyCommands, AdvancedJedisCommands, ScriptingCommands {
public Jedis(final String host) {
super(host);
}

public Jedis(final String host, final int port) {
super(host, port);
}

public Jedis(final String host, final int port, final int timeout) {
super(host, port, timeout);
}

public Jedis(JedisShardInfo shardInfo) {
super(shardInfo);
}

public Jedis(URI uri) {
super(uri);
}
//omitted

}

when I want to proxy jedis, the constructor for such is for such
public Jedis(final String host, final int port, final int timeout) {
super(host, port, timeout);
}

so here comes the class info and arguments comes like this
Class[] args = new Class[] {String.class, Integer.class, Integer.class};

Object[] arguments = new Object[] {jedis.getClient().getHost(), jedis.getClient().getPort(),
jedis.getClient().getTimeout()};

if such above is not wrong, the cglib will help to create the proxy class with enhancer. but here comes my exception stracktrace:
Caused by: java.lang.NoSuchMethodException: redis.clients.jedis.Jedis$$EnhancerByCGLIB$$e2ffdb0f.(java.lang.String, java.lang.Integer, java.lang.Integer)
at java.lang.Class.getConstructor0(Class.java:2902)
at java.lang.Class.getDeclaredConstructor(Class.java:2066)
at net.sf.cglib.core.ReflectUtils.getConstructor(ReflectUtils.java:244)
... 14 more

I don't know the reason and whether I was wrong. hope someone could point out my mistake with cglib.

Could anybody who encounter the similar use case leave me some advice on how to resolve such problem ?

You are using Integer wrapper objects instead of primitive ints when trying to locate the constructor. Therefore, the lookup fails.

@raphw, thanks for review. and it should work with the type corrections. I will continue to get to know about cglib with its use cases.
