spring2.5.6 错误

 

public class MessageWriter {

    public void writerMessage() {
        System.out.println("i'm working");
    }
}

public class MessageDecorator implements MethodInterceptor{

    @Override
    public Object invoke(MethodInvocation methodInvocation) throws Throwable {
        System.out.println("before...");
        Object retVal = methodInvocation.proceed();
        System.out.println("after...");
        return retVal;
    }

    
}

public class MessageWeaver {

    public static void main(String[] args) {
        // joint point
        MessageWriter target = new MessageWriter();

        // create the proxy
        ProxyFactory pf = new ProxyFactory();
        // add advice
        pf.addAdvice(new MessageDecorator());
        pf.setTarget(target);

        MessageWriter proxy = (MessageWriter) pf.getProxy();
        target.writerMessage();
        System.out.println("------------");
        proxy.writerMessage();
    }

}

 

 

 在测试就项目时使用上述测试代码如下jars⑩

 spring2.5.6.jar

 commons-logging-1.2.jar

 cglib-full-2.0.2.jar

 aspectjweaver-1.8.0.RELEASE.jar

 

测试类报如下错误

 

Exception in thread "main" java.lang.NoSuchMethodError: net.sf.cglib.proxy.Enhancer.setInterceptDuringConstruction(Z)V

经过分析使用cglib-2.1_3.jar和asm-1.5.3.jar代替cglib-full-2.0.2.jar

问题解决
