在 spring 中使用 PointCut 时出现异常

Exception while using PointCut in spring

看点Class:

 import org.aspectj.lang.annotation.AdviceName;
 import org.aspectj.lang.annotation.Aspect;
 import org.aspectj.lang.annotation.Before;
 import org.aspectj.lang.annotation.Pointcut;

@Aspect
public class LoggingAspect {


@Before("allCircleMethods()")
public void LoggingAdvice() {
    System.out.println("Advice Run: Get Method Called:");
}

@Before("args(String)")
public void StringArgumentMethod(String name) {
    System.out.println("Method That takes String Argument is calling  value of that string is "+name);
}

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

@Pointcut("within(com.cisco.kapil.model.Circle)")
public void allCircleMethods() {}    }

主要Class:

 public class AopMain {
public static void main(String args[]) {
    ApplicationContext ctx = new ClassPathXmlApplicationContext("spring.xml");
    ShapeService shapeservice = ctx.getBean("ShapeService", ShapeService.class);
    shapeservice.getCircle().setName("My Own Circle");
    //System.out.println(shapeservice.getCircle().getName());
}   }

形状Class:

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="com.cisco.kapil.aspect.LoggingAspect" />
    </beans>

圆圈:

public class Circle {
private String name;

public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
    System.out.println("Circle Setter is called");
}  }

三角形:

public class Triangle {
private String name;

public String getName() {
    return name;
}

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

异常:

在你的 LoggingAspect.java class 中应该 @After

 @After("args(name)")
public void StringArgumentMethod(String name) {
    System.out.println("Method take string argument is calling "+name);
}
