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

Question

我使用spring + spring security + hibernate在netbeans中开发应用程序并在tomcat中运行。我试图将这个项目移动到谷歌应用引擎，所以我决定将它移动到日食，因为我认为考虑到eclipse有GAE的插件更容易。

    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

我的项目有什么问题吗？我也把这个lib放在我的App Engine lib / impl中，而且还没有工作......

ps：可能与Error : java.lang.NoSuchMethodError: org.objectweb.asm.ClassWriter.<init>(I)V有关，但我仍然无法修复我的项目..请帮助..提前感谢。

Answer 1

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。< / p>

如果存在不兼容的库，则通常会发生此类错误：一个库需要lib B的x版本，但是你的版本是lib B.这两个版本不兼容。

如果您的项目是使用Netbeans运行的，而不是使用Eclipse运行，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。

在你的情况下，来自DebuggingClassWriter的类cgilib-2.2.jar在其构造函数中调用来自ClassWriter的超类asm.jar的构造函数（带有一个布尔参数）（很遗憾，你没有指定了您使用的asm.jar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：我将cglib-nodep-2.2.jar与asm-3.1.jar一起使用，并且有效
