添加到类路径的jar:

对我来说，它在类路径上与此配合得很好（我不是故意使用Maven，而是手动在Eclipe中添加了所有lib以复制您的设置）：

方面的输出将按预期显示在控制台上。也许你想比较一下你的LIB和我的LIB。不过，我强烈建议使用Maven作为构建工具。这样，您可以更好地控制依赖关系

编辑：我忘了提到我的Eclipse项目是AspectJ项目，而不是普通的Java项目。也就是说，我使用ajc作为编译器，而不是javac。结果是编译时编织。如果您想使用加载时编织，请告诉我，我将以这种方式进行测试

编辑2:我刚刚将我的项目转换为一个普通的Java项目，即javac编译所有类/方面，现在使用带LTW的Spring AOP应用方面。它仍然完美无缺地工作。我当前的库设置如下所示：

因此，由于aopalliance jar不正确，我遇到了相同的问题。 我之前拥有的是aopalliance-alpha1.jar

但后来我把它改成了aopalliance-1.0.jar，你可以从这里下载

该程序正在为我工作。

也有相同的错误。我下载了

aopalliance-1.0-sources.jar

和

aspectjweaver-1.7.1-sources.jar

，而不是

aopalliance-1.0.jar

和

aspectjweaver-1.7.1.jar

（不带“source”）。下载正确的JAR（@kriegaex links）后，它工作正常。

谢谢你的提问，我遇到了完全相同的错误，这纯粹是Jar错误。我通过使用asm-3.3.1.jar、aspectjrt.jar、cglib-3.1.jar、aopalliance-1.0.jar和aspectweaver-1.7.2.jar解决了这个问题。我认为这是由于它的广度和aspectweaver依赖性造成的。希望对您有所帮助

我也遇到过同样的问题，我相信你也像我一样关注java大脑：）

只需将aopalliance-jar更改为aopalliance1.0-jar，它对我很有效。

我的AspectJ库包含以下jar是什么意思？你在哪里有这些库？@SotiriosDelimanolis我的意思是我有一个用户库名aspectJ，其中包括我列出的JAR，我下载了所有JAR，制作了一个自定义库，并将其包含在我的spring AOP项目中。我不知道你所说的用户库是什么意思。你用的是什么IDE？如何运行应用程序？您是否在运行时类路径中包含列出的库？@SotiriosDelimanolis是的，将其包含在我的运行时类路径中。我正在使用Eclipse Lunar，您能否使用
