方法详细资料

intercept

@Nullable
Object intercept(Object obj,
 Method method,
 Object[] args,
 MethodProxy proxy)
          throws Throwable

All generated proxied methods call this method instead of the original method. The original method may either be invoked by normal reflection using the Method object, or by using the MethodProxy (faster).

参数:

obj - "this", the enhanced object

method - intercepted Method

args - argument array; primitive types are wrapped

proxy - used to invoke super (non-intercepted method); may be called as many times as needed

返回:

any value compatible with the signature of the proxied method. Method returning void will ignore this value.

抛出:

Throwable - any exception may be thrown; if so, super method will not be invoked
