org.springframework.aop.framework
Class Cglib2AopProxy

java.lang.Object
  org.springframework.aop.framework.Cglib2AopProxy

All Implemented Interfaces:

Serializable, AopProxy

---

public class Cglib2AopProxy
extends Object
implements AopProxy, Serializable

CGLIB2-based AopProxy implementation for the Spring AOP framework. Requires CGLIB2 on the class path.

Built and tested against CGLIB 2.0.2, as of Spring 1.1. It is recommended to use CGLIB 2.1+.

Objects of this type should be obtained through proxy factories, configured by an AdvisedSupport object. This class is internal to Spring's AOP framework and need not be used directly by client code.

DefaultAopProxyFactory will automatically create CGLIB2-based proxies if necessary, for example in case of proxying a target class (see the attendant javadoc for details).

Proxies created using this class are thread-safe if the underlying (target) class is thread-safe.

Field Detail

logger

protected static final Log logger

Logger available to subclasses; static to optimize serialization

---

advised

protected final AdvisedSupport advised

The configuration used to configure this proxy

Constructor Detail

Cglib2AopProxy

protected Cglib2AopProxy(AdvisedSupport config)
                  throws AopConfigException

Create a new Cglib2AopProxy for the given AOP configuration.

Throws:

AopConfigException - if the config is invalid. We try to throw an informative exception in this case, rather than let a mysterious failure happen later.

Method Detail

setConstructorArguments

protected void setConstructorArguments(Object[] constructorArgs,
                                       Class[] constructorArgTypes)

Set constructor arguments to use for creating the proxy.

Parameters:

constructorArgs - the constructor argument values

constructorArgTypes - the constructor argument types

---

getProxy

public Object getProxy()

Description copied from interface: AopProxy

Create a new proxy object.

Uses the most optimal default class loader (if necessary for proxy creation): usually, the thread context class loader.

Specified by:

getProxy in interface AopProxy

See Also:

Thread.getContextClassLoader()

---

getProxy

public Object getProxy(ClassLoader classLoader)

Description copied from interface: AopProxy

Create a new proxy object.

Uses the given class loader (if necessary for proxy creation). null will simply be passed down and thus lead to the low-level proxy facility's default, which is usually different from the default chosen by the AopProxy implementation's getProxy method.

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)

---

createEnhancer

protected Enhancer createEnhancer()

Creates the CGLIB Enhancer. Subclasses may wish to override this to return a custom Enhancer implementation.

---

equals

public boolean equals(Object other)

Overrides:

equals in class Object

---

hashCode

public int hashCode()

Overrides:

hashCode in class Object
