I am trying to use the spring AOP framework. The code compiled without error. When I tried to run it, I got the above exception. I am using netbeans IDE 8.0.1. I have the following libraries and jar files included.
我正在尝试使用 spring AOP 框架。代码编译没有错误。当我尝试运行它时，出现上述异常。我使用的是 netbeans IDE 8.0.1。我包含以下库和 jar 文件。
1) Spring Framework 4.0.1
2) aspectjrt.jar
3) aspectjweaver.jar
4) aopalliance-alpha1.jar
5) asm-5.03.jar
6) cglib-3.1.jar
Here is my spring.xml config file

These are the latest jar files that are available from each publisher. I did not see the Advice class anywhere in the aopalliance jar. I searched for this problem. It appears that the Advice class may have been removed from the aopalliance jar. I have not been able to search it. Does anyone know how to resolve this problem other than telling me to use Maven :) ?
这些是每个发布者提供的最新 jar 文件。我在 aopalliance jar 的任何地方都没有看到 Advice 类。我搜索了这个问题。似乎 Advice 类可能已从 aopalliance jar 中删除。我一直无法搜索它。除了告诉我使用 Maven 之外，有没有人知道如何解决这个问题:)？

I had the same error as I had added aopalliance-alpha1.jar instead of aopalliance.jar. I added the correct jar and it started working .
我有同样的错误，因为我添加了 aopalliance-alpha1.jar 而不是 aopalliance.jar。我添加了正确的 jar 并开始工作。

I also got the same error in my eclipse env.
我的 eclipse env 也遇到了同样的错误。
Cause : For working on spring aop examples, from the net I downloaded the files 'aopalliance-.jar.zip', 'aspectj-1.6.9.jar.zip', 'aspectjrt.jar.zip', 'aspectj-weaver.jar.zip' and included it directly in the java build path. The mistake I did here was I didn't extract the jar files from the zip file, instead directly added the .jar.zip file into the java build path.
原因：为了处理 spring aop 示例，我从网上下载了文件“aopalliance-.jar.zip”、“aspectj-1.6.9.jar.zip”、“aspectjrt.jar.zip”、“aspectj-weaver”。 jar.zip' 并将其直接包含在 java 构建路径中。我在这里犯的错误是我没有从 zip 文件中提取 jar 文件，而是直接将 .jar.zip 文件添加到 java 构建路径中。
Fix : Extract the jar files from above mentioned .jar.zip files and in the eclipse point to the jar files instead of zip files, then it will start working.
修复：从上面提到的 .jar.zip 文件中提取 jar 文件，并在 eclipse 中指向 jar 文件而不是 zip 文件，然后它将开始工作。
