直接已知子类:
SerializationCglibAopProxy
class CglibAopProxy extends Object implements AopProxy, Serializable
CGLIB-based AopProxy implementation for the AOP framework.

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

DefaultAopProxyFactory will automatically create CGLIB-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.

      public CglibAopProxy(AdvisedSupport config)
      Create a new CglibAopProxy for the given AOP configuration.
      参数:
      config - the AOP configuration as AdvisedSupport object
      抛出:
      AopConfigException - if the config is invalid. We try to throw an informative exception in this case, rather than let a mysterious failure happen later.

    • setConstructorArguments

      public void setConstructorArguments(@Nullable Object[] constructorArgs, @Nullable Class<?>[] constructorArgTypes)
      Set constructor arguments to use for creating the proxy.
      参数:
      constructorArgs - the constructor argument values
      constructorArgTypes - the constructor argument types

    • getProxy

      public Object getProxy()
      从接口复制的说明: AopProxy
      Create a new proxy object.

      Uses the AopProxy's default class loader (if necessary for proxy creation): usually, the thread context class loader.

      指定者:
      getProxy 在接口中 AopProxy
      返回:
      the new proxy object (never null)
      另请参阅:

    • getProxy

      public Object getProxy(@Nullable ClassLoader classLoader)
      从接口复制的说明: 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 AopProxy.getProxy() method.

      指定者:
      getProxy 在接口中 AopProxy
      参数:
      classLoader - the class loader to create the proxy with (or null for the low-level proxy facility's default)
      返回:
      the new proxy object (never null)

    • getProxyClass

      public Class<?> getProxyClass(@Nullable ClassLoader classLoader)
      从接口复制的说明: AopProxy
      Determine the proxy class.
      指定者:
      getProxyClass 在接口中 AopProxy
      参数:
      classLoader - the class loader to create the proxy class with (or null for the low-level proxy facility's default)
      返回:
      the proxy class

    • validateClassIfNecessary

      void validateClassIfNecessary(Class<?> proxySuperClass, @Nullable ClassLoader proxyClassLoader)
      Checks to see whether the supplied Class has already been validated and validates it if not.

    • doValidateClass

      void doValidateClass(Class<?> proxySuperClass, @Nullable ClassLoader proxyClassLoader, Set<Class<?>> ifcs)
      Checks for final methods on the given Class, as well as package-visible methods across ClassLoaders, and writes warnings to the log for each one found.

    • implementsInterface

      static boolean implementsInterface(Method method, Set<Class<?>> ifcs)
      Check whether the given method is declared on any of the given interfaces.

      Exception

    • createEnhancer

      protected infra.bytecode.proxy.Enhancer createEnhancer()
      Creates the CGLIB Enhancer. Subclasses may wish to override this to return a custom Enhancer implementation.

      Throwable

    • processReturnValue

      @Nullable private static Object processReturnValue(Object proxy, @Nullable Object target, Method method, @Nullable Object retVal)
