创建JUnit测试时没有此类方法错误

Question

我已经尝试了过去两天没有运气的问题。我只是试图使用spring框架和hibernate创建一个基于注释的JUnit测试。

我的IDE是netbeans 6.5，我正在使用hibernate3，spring2.5.5和JUnit 4.4。

这是我得到的错误：

Answer 1

将java.lang.NoSuchMethodError始终表明，一类是在你的编译器的类路径的版本是从上运行时类路径类的版本不同（有方法在编译时失踪，编译就失败了。）

在这种情况下，org.objectweb.asm.ClassWriter编译时在类路径上的版本与运行时类路径上的版本不同。
