正式结合的切入点的Spring AOP的错误

Question

嗨，我使用Spring AOP的在我的应用我得到了下面的代码行 LoggingAspect.java

@Aspect 
public class LoggingAspect { 
    @Before("allCircleMethods()") 
    public void loggingAdvice(Joinpoint joinPoint) 
    { 
     System.out.println("get method is called"+joinPoint.toString()); 
    } 

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


    @Pointcut("within(org.com.revanth.model.Circle)") 
    public void allCircleMethods(){} 
} 

Circle.java

public class Circle { 

    private String name; 

    public String getName() { 
     return name; 
    } 

    public void setName(String name) { 
     this.name = name; 
    } 

} 

错误Traingle.java

public class Traingle { 

    private String name; 

    public String getName() { 
     return name; 
    } 

    public void setName(String name) { 
     this.name = name; 
    } 

} 

ShapeService.java

public class ShapeService { 

    private Circle circle; 
    private Triangle triangle; 

    public Circle getCircle() { 
     return circle; 
    } 
    public void setCircle(Circle circle) { 
     this.circle = circle; 
    } 
    public Triangle getTriangle() { 
     return triangle; 
    } 
    public void setTriangle(Triangle triangle) { 
     this.triangle = triangle; 
    } 
} 

spring.xml

    <bean name="loggingAspect" class="org.com.revanth.aspect.LoggingAspect"></bean> 
</beans> 

AopMain.java

public class AopMain { 

    public static void main(String[] args) { 
     // TODO Auto-generated method stub 
     ApplicationContext ctx = new ClassPathXmlApplicationContext("spring.xml"); 
     ShapeService shapeService = (ShapeService) ctx.getBean("shapeService", ShapeService.class); 
     System.out.println(shapeService.getCircle().getName()); 
    } 

} 

我收到正式的未绑定的错误切入点expression.the错误堆栈跟踪如下：

任何人都可以帮我解决上述错误吗？任何帮助，将不胜感激。

Answer 1

@Pointcut("within(org.com.revanth.model.Circle)") 
public void allCircleMethods(){} 

应该

@Pointcut("within(org.com.revanth.model.Circle.*)") 
public void allCircleMethods(){}
