对 Spring AOP 使用 Pointcut 不起作用，否则效果很好。请帮我解决这个问题。

没有切入点工作代码：

@Before("execution(public * spring.beans.Triangle.set*(*))")    
public void beforeonlySetTriangle_FirstAspect()
{
    System.out.println("beforeonlySetTriangle_FirstAspect only for Triangle is called");
}
@Before("execution(public * spring.beans.Triangle.set*(*))")    
public void beforeonlySetTriangle_SecondAspect()
{
    System.out.println("beforeonlySetTriangle_SecondAspect only for Triangle is called");
}

使用切入点代码给出错误：

@Before("setTrianglePointCutter()") 
public void beforeonlySetTriangle_FirstAspect()
{
    System.out.println("beforeonlySetTriangle_FirstAspect only for Triangle is called");
}
@Before("setTrianglePointCutter()") 
public void beforeonlySetTriangle_SecondAspect()
{
    System.out.println("beforeonlySetTriangle_SecondAspect only for Triangle is called");
}

@Pointcut("execution(public * spring.beans.Triangle.set*(*))")
public void setTrianglePointCutter()
{

}

例外 ：

从这篇文章看来，旧版本的运行时 AspectJ jar 会发生错误。升级到最新版本aspectjrt，即1.7.3

有时由于 aspectj jar 的版本冲突会导致这个问题，对我来说就是这种情况。我刚刚删除了 aspectjtools 依赖项，将 aspectjrt、aspectjweaver 更新到了最新版本，它解决了我的问题
