spring - Google Apps Engine 上的 Spring + Hibernate 错误 (java.lang.NoClassDefFoundError: org/objectweb/asm/ClassWriter)

Question

我有使用 spring + spring security + hibernate 使用 netbeans 开发的应用程序，并在 tomcat 中运行。我试图将此项目移至 Google App Engine，因此我决定将其移至 Eclipse，因为考虑到 Eclipse 具有 GAE 插件，我认为它更容易。

    org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'mySessionFactory' defined in ServletContext resource [/WEB-INF/dispatcher-servlet.xml]: Invocation of init method failed; nested exception is java.lang.NoSuchMethodError: org.objectweb.asm.ClassWriter.<init>(Z)V
    Caused by: java.lang.NoSuchMethodError: org.objectweb.asm.ClassWriter.<init>(Z)V

这是我的调度员 servlet

我的项目有问题吗？我还将该库放在我的 App Engine lib/impl 中，但也无法正常工作...

ps：可能与错误有关：java.lang.NoSuchMethodError: org.objectweb.asm.ClassWriter.<init>(I)V但我仍然没有修复我的项目..请帮助..提前谢谢。

Answer 1

A java.lang.NoSuchMethodError（在您的情况下（java.lang.NoSuchMethodError: org.objectweb.asm.ClassWriter.<init>(Z)V））表示类（ClassWriter）存在，但方法（在您的情况下：带有布尔参数的构造函数）不存在。

如果存在不兼容的库，则经常会出现这种错误：一个库需要lib B的x版本，但您有lib B的y版本。这两个版本不兼容。

如果您的项目使用 Netbeans 运行，但没有使用 Eclipse，那么我猜您在将项目从一个 IDE 移动到另一个 IDE 时修改了库。

在您的情况下，Class DebuggingClassWriterfromcgilib-2.2.jar在其构造函数中调用其超类的构造函数（带有一个布尔参数）ClassWriterfrom asm.jar（不幸的是，您没有指定asm.jar您使用的版本）。但我可以告诉你，例如asm-3.1.jar包含你需要的构造函数。

顺便说一句：我cglib-nodep-2.2.jar与 一起使用asm-3.1.jar，它可以工作
