异常而在弹簧使用切入点

Question

方面类：

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() {} } 

主类：

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()); 
} } 

形状等级：

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：

    <beans xmlns="http://www.springframework.org/schema/beans" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<aop:aspectj-autoproxy />

     <property name="name" value="Triangle name" /> 
    </bean> 


    <bean name="circle" class="com.cisco.kapil.model.Circle"> 
     <property name="name" value="Circle Name" /> 
    </bean> 

    <bean name="ShapeService" class="com.cisco.kapil.service.ShapeService" autowire="byName" /> 

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

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：

public class Triangle { 
private String name; 

public String getName() { 
    return name; 
} 

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

Answer 1

在LoggingAspect.java类

应该@After

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