public class ProxyFactory extends ProxyCreatorSupport
Factory for AOP proxies for programmatic use, rather than via declarative setup in a bean factory. This class provides a simple way of obtaining and configuring AOP proxy instances in custom user code.

  • Constructor Details

    • 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 Details

    • 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).

      Returns:
      the proxy object

    • getProxy

      public Object getProxy(@Nullable 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).

      Parameters:
      classLoader - the class loader to create the proxy with (or null for the low-level proxy facility's default)
      Returns:
      the proxy object

    • getProxyClass

      public Class<?> getProxyClass(@Nullable ClassLoader classLoader)
      Determine the proxy class according to the settings in this factory.
      Parameters:
      classLoader - the class loader to create the proxy class with (or null for the low-level proxy facility's default)
      Returns:
      the proxy class

    • getProxy

      public static <T> T getProxy(Class<T> 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

    • getProxy

      public static <T> T getProxy(Class<T> 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:

    • 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
