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

Since:

6.0

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

See Also:

• ProxyFactory(Class, org.aopalliance.intercept.Interceptor)

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:

• 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
