logging - 从 joinPoint 获取行号

Question

我正在尝试从我的周围建议中的连接点 Sourcelocation 访问行号(用于记录目的)。 但它正在给予

Exception in thread "main" java.lang.UnsupportedOperationException
at org.springframework.aop.aspectj.MethodInvocationProceedingJoinPoint$SourceLocationImpl.getLine(MethodInvocationProceedingJoinPoint.java:282)

调试时 loc.getLine() 为 null。

@Around("execution (* com.logger.rms.*.*(..))")
public void logAround(ProceedingJoinPoint procJoinpoint) throws Throwable {
  StaticPart part = (procJoinpoint.getStaticPart());
  org.aspectj.lang.reflect.SourceLocation loc = part.getSourceLocation();
  int line = loc.getLine();
  System.out.println(line);

  try {
    procJoinpoint.proceed();
  } catch (Throwable e) {
    System.out.println("checking " + procJoinpoint.getSourceLocation().getWithinType().getCanonicalName());
    String str = "Aspect ConcreteTester :" + procJoinpoint.getStaticPart().getSourceLocation().getLine();
    throw new BusinessLogicException("Throwing Custom business exception from around");
  } finally {
  }
}

它从来没有工作过，请参阅来源 code here

private class SourceLocationImpl implements SourceLocation {

    ...

    @Override
    public String getFileName() {
        throw new UnsupportedOperationException();
    }

    @Override
    public int getLine() {
        throw new UnsupportedOperationException();
    }
}
