Question

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

没有Pointcut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Pointcut代码会出错：

@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：

Answer 1

从this post看来，旧版本的运行时AspectJ jar发生错误。升级到aspectjrt的最新版本，即1.7.3

Answer 2

有时因为aspectj jar的版本冲突会引起我的问题。我刚刚删除了aspectjtools依赖，更新了aspectjrt，aspectjweaver到最新版本，它解决了我的问题
