我的主要课程：
public class SpringDemo {
public static void main(String[] args) {
final ApplicationContext applicationContext = new ClassPathXmlApplicationContext("knights-aop.xml");
final Knight braveKnight = (Knight) applicationContext.getBean("knight");
braveKnight.embarkOnQuest();
}
}
我还尝试添加：aopalliance.jar& aopalliance-alpha1.jar单独和一起但错误不会消失。
I also tried adding: aopalliance.jar & aopalliance-alpha1.jar individually and together but the error won't go away.

我使用的是Spring 3.2
################## EDIT2 ##################
我没有使用Maven。除非没有Spring AOP，否则请不要提供Maven相关的解决方案。
项目快照：
里面的SPRING LIBRARY我有所有用Spring下载的jar。是否有可能某些弹簧特定的罐子与aopalliance jar相冲突？
如果有人有类似的&没有Maven的简单工作示例，请提供。
谢谢

I am using Spring 3.2
##################EDIT2##################
I am not using Maven. Please don't provide Maven related solution unless Spring AOP is impossible without it.
Project Snap:
Inside SPRING LIBRARY I have all the jar that got downloaded with Spring. Is it possible that some spring specific jar conflicting with aopalliance jar?
If anyone has some similar & simple working example without Maven, please provide it.
Thanks

推荐答案
我完全删除了SPRING-LIBRARY，然后逐个添加了所有必需的jar和cglib-nodep-2.2.jar。
我的代码中也有拼写错误< bean id =questclass =com.java.spring.ResqueDamselQuest/>
I removed SPRING-LIBRARY completely and then added all the required jars one by one plus cglib-nodep-2.2.jar.
There was also a spelling mistake in my code <bean id="quest" class="com.java.spring.ResqueDamselQuest" />
public class RescueDamselQuest implements Quest {
类的名称。
但我确信这个拼写错误不是我得到的例外的原因。从头开始添加罐子之后，我得到了这个错误，表示没有像knights-aop.xml中所提到的那样找到......某些......这就是我认为我有这个错字的时候。
But I am sure this spelling mistake was not the reason for the exception I was getting. After adding the jars from scratch I got this error that said the bean is not found as mentioned in the knights-aop.xml sth.. sth... which is when I figured that I have this typo.
这就是我现在添加罐子的方式：
This is how my jars are added now:
我希望有人可以从这个答案中获得帮助。
I hope someone might get help from this answer.
###########编辑###########
asm-all& cglib-nodep不是必需的。此外，春季下载的一些jar导致了问题，因为我尝试添加我在春季下载中获得的所有罐子，并且它再次开始显示旧的异常。因此，最好在需要时添加jar。
asm-all & cglib-nodep are not required. Also, some jar from spring download was causing problems, as I tried adding all the jars I got in spring download and it started showing the old exception again. So it is better to add jar as and when required.
