原因

这两个注解虽然不会爆红，但是没有指定execution还是会在运行时出现异常。

解决

@Before(\"pt1()\")public void beforePrintLog(){System.out.println(\"前置。Logger类的printLog方法开始记录日志了。beforePrintLog\");}@AfterReturning(\"pt1()\")public void afterReturningPrintLog(){System.out.println(\"后置。Logger类的printLog方法开始记录日志了。afterReturningPrintLog\");}@AfterThrowing(\"pt1()\")public void afterThrowingPrintLog(){System.out.println(\"异常。Logger类的printLog方法开始记录日志了。afterThrowingPrintLog\");}@After(\"pt1()\")public void afterPrintLog(){System.out.println(\"最终。Logger类的printLog方法开始记录日志了。afterPrintLog\");}
