All Implemented Interfaces:
  Serializable, Advised, AopProxy, TargetClassAware

    public class ProxyFactory

extends ProxyCreatorSupport
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)

  Create a new ProxyFactory.

  Will proxy all interfaces that the given target implements.

  Parameters:
    `target` - the target object to be proxied

### ProxyFactory

    public ProxyFactory(Class[] proxyInterfaces)

  Create a new ProxyFactory.

  No target, only interfaces. Must add interceptors.

  Parameters:
    `proxyInterfaces` - the interfaces that the proxy should implement

### ProxyFactory

    public ProxyFactory(Class proxyInterface,
                        Interceptor interceptor)

  Create a new ProxyFactory 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

### ProxyFactory

    public ProxyFactory(Class proxyInterface,
                        TargetSource targetSource)

  Create a ProxyFactory for the specified `TargetSource`, making the proxy implement the specified interface.

  Parameters:
    `proxyInterface` - the interface that the proxy should implement
    `targetSource` - the TargetSource that the proxy should invoke

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 proxy object
  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 (or `null` for the low-level proxy facility's default)
  Returns:
    the proxy object

### 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 proxy object
  See Also:
    `ProxyFactory(Class, org.aopalliance.intercept.Interceptor)`

### getProxy

    public static Object getProxy(Class proxyInterface,
                                  TargetSource targetSource)

  Create a proxy for the specified `TargetSource`, implementing the specified interface.

  Parameters:
    `proxyInterface` - the interface that the proxy should implement
    `targetSource` - the TargetSource that the proxy should invoke
  Returns:
    the proxy object
  See Also:
    `ProxyFactory(Class, org.springframework.aop.TargetSource)`

### getProxy

    public static Object getProxy(TargetSource targetSource)

  Create a proxy for the specified `TargetSource` that extends the target class of the `TargetSource`.

  Parameters:
    `targetSource` - the TargetSource that the proxy should invoke
  Returns:
    the proxy object
