【问题描述】:
在我启动所有项目单元测试之前,一切似乎都很完美。 将我的项目从 2.2.1.1 升级到 struts 2.3.15.1 后,出现以下错误:
java.lang.NoSuchMethodError: org.objectweb.asm.ClassWriter.<init>(Z)V
at net.sf.cglib.core.DebuggingClassWriter.<init>(DebuggingClassWriter.java:47)
at net.sf.cglib.core.DefaultGeneratorStrategy.getClassWriter(DefaultGeneratorStrategy.java:30)

at net.sf.cglib.proxy.Enhancer.<clinit>(Enhancer.java:69)
问题实际上是struts 2.3.15.1 使用了另一个版本的asm 框架,它不同于以前的版本。这里是 mvn 树的结果

如您所见,struts 使用 asm 3.3,它不是在 hibernate transitive dependency 中定义的。我的解决方案我从我的 struts 声明中排除了这种依赖关系
<dependency>
<groupId>org.apache.struts</groupId>
<artifactId>struts2-core</artifactId>
<version>2.3.15.1</version>
<exclusions>
<exclusion>
<groupId>asm</groupId>
<artifactId>asm</artifactId>
</exclusion>
</exclusions>
</dependency>
问题已解决,但我现在遇到了新的错误,我不知道是什么。?

正如您提到的,当一个类依赖于其他类并且该类在编译后发生不兼容的更改时,就会出现此问题。
