Spring AOP错误：java.lang.NoClassDefFoundError：org / springframework / cglib / core / SpringNamingPolicy

Question

我正在尝试使用单个Aspect创建一个简单的AOP应用程序。我能够成功注入对象。但是当我试图在spring-context.xml中包含AOP配置时，我收到以下错误： -

Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'triangle' defined in class path resource [spring1-context.xml]: Initialization of bean failed; nested exception is java.lang.NoClassDefFoundError: org/springframework/cglib/core/SpringNamingPolicy

我的代码是：

public class Triangle {
    private String name;

    public String getName() {
        return name;
    }

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



}


public class Circle {
    private String name;

    public String getName() {
        return name;
    }

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



}

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;
    }



}

@Aspect
public class LoggingAspect {

    @Before("execution(public String getName())")
    public void loggingAdvice(){
        System.out.println("Aspect called - method executed");
    }
}


public class AOPMain {
    public static void main(String[] args) {

        ApplicationContext context = new ClassPathXmlApplicationContext("spring1-context.xml");
        ShapeService service = context.getBean("shapeService", ShapeService.class);

        System.out.println(service.getCircle().getName());
        System.out.println(service.getTriangle().getName());
    }

}

我的弹簧配置文件是：

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

    http://www.springframework.org/schema/aop/spring-aop-3.0.xsd ">

    <aop:aspectj-autoproxy />

      <bean id="triangle" class="aopExample.Triangle">
        <property name="name" value="Triangle name"></property>
      </bean>

      <bean id="circle" class="aopExample.Circle">
        <property name="name" value="Circle Name"></property>
      </bean>

      <bean id="shapeService" class="aopExample.ShapeService" autowire="byName">

      </bean>
      <bean id="loggingAspect" class="aopExample.LoggingAspect"></bean>
</beans>

这是我的pom.xml：

任何人都可以帮我解决这个问题。

提前致谢。

您可以解决针对4.0.0.RELEASE版本运行的问题。尝试使用下面的pom.xml。
