您好我正在使用hibernate2开发一个小应用程序，我碰到了读取java.lang.NoSuchMethodError的异常：org.objectweb.asm.ClassWriter

这是stacktrace：

任何帮助，请

Answer 1

您需要在类路径中使用正确版本的asm jar

Answer 2

你的lib有些冲突。 hibernate使用 cglib-xxxx.jar ，它使用 asm-xxxx.jar 。并且有可能在您的项目中使用这些jar的多个版本，或者您正在使用的其他库也可能对某些其他版本有一些依赖性，因此它会相互冲突。
您需要删除 cglib-xxxx.jar 并替换为 cglib-nodep-xxxx.jar 并使用最新的 asm-xxxx.jar 或尝试从hibernate依赖项中删除 asm-xxxx.jar ，因为 cglib-nodep-xxx.jar 会查找另一个最新的 asm-xxxx.jar < / strong>在您的项目或Web服务器库中。您可以从链接中找到 cglib-nodep lib 的 http://sourceforge.net/projects/cglib/files/
