package sam; 

import org.aspectj.lang.annotation.Aspect; 
import org.aspectj.lang.annotation.Before; 
import org.aspectj.lang.annotation.Pointcut; 

@Aspect public class LoggingAspect { 
  @Before("get()") 
  public void LoggingAdvice() { 
    System.out.println("Good Afternoon"); 
  } 

  @Before("get()") 
  public void LAdvice() { 
    System.out.println("Good Morning"); 
  } 

  @Pointcut("execution(* get*())") 
  public void get() { } 
}

根据spring aop doc

完整的AspectJ切入点语言支持Spring中不支持的其他切入点指示符。它们是：call，get，set，preinitialization，staticinitialization，initialization，handler，adviceexecution，withincode，cflow，cflowbelow，if，@ this和@withincode。

所以我假设您应该避免Spring Aop中的命名冲突
