public class ProxyFactory
extends AdvisedSupport
implements AopProxy

Factory for AOP proxies for programmatic use, rather than via a bean factory. This class provides a simple way of obtaining and configuring AOP proxies in code.

Constructor Detail

ProxyFactory

public ProxyFactory()
Create a new ProxyFactory.


ProxyFactory

public ProxyFactory(Object target)
             throws AopConfigException
Create a new ProxyFactory.

Will proxy all interfaces of the given target.

Parameters:
target - the target object that is to be proxied
Throws:
AopConfigException - if the supplied target object is null

ProxyFactory

public ProxyFactory(Class[] interfaces)
Create a new ProxyFactory. No target, only interfaces. Must add interceptors.

Method Detail

getProxy

public Object getProxy()
Create a new proxy according to the settings in this factory. Can be called repeatedly. Effect will vary if we've added or removed interfaces. Can add and remove interceptors.

Uses a default class loader: Usually, the thread context class loader (if necessary for proxy creation).

Specified by:
getProxy in interface AopProxy
Returns:
the new proxy
See Also:
Thread.getContextClassLoader()

getProxy

public Object getProxy(ClassLoader classLoader)
Create a new proxy according to the settings in this factory. Can be called repeatedly. Effect will vary if we've added or removed interfaces. Can add and remove interceptors.

Uses the given class loader (if necessary for proxy creation).

Specified by:
getProxy in interface AopProxy
Parameters:
classLoader - the class loader to create the proxy with
Returns:
the new proxy

getProxy

public static Object getProxy(Class proxyInterface,
                              Interceptor interceptor)
Create a new proxy for the given interface and interceptor.

Convenience method for creating a proxy for a single interceptor, assuming that the interceptor handles all calls itself rather than delegating to a target, like in the case of remoting proxies.

Parameters:
proxyInterface - the interface that the proxy should implement
interceptor - the interceptor that the proxy should invoke
Returns:
the new proxy

getProxy

public static Object getProxy(Class proxyInterface,
                              TargetSource targetSource)
Create a proxy for the specified TargetSource that implements the specified interface.


getProxy

public static Object getProxy(TargetSource targetSource)
Create a proxy for the specified TargetSource that extends the target class of the TargetSource.
