当我尝试运行项目或启动Tomcat时，我不断收到此错误：

从SVN获得更新后发生此问题。看起来MetalCikisIslemleriBean类中存在一些不兼容性。我搜索了这个异常并作为我添加的解决方案

private static final long serialVersionUID = 5362381638722129852L;

到MetalCikisIslemleriBean，但它仍然没有好处。 Tomcat没有开始。有没有人对此问题有任何建议？提前致谢。

编辑： 我安装了另一个Tomcat版本，但仍然没有好处。我在Tomcat的工作和删除下删除了文件。临时目录和项目的构建文件夹。这次Tomcat运行，清洁＆amp;项目建设很好，但仍然没有运行。我意识到在项目的backingbeans文件夹中有2个MetalCikisIslemleriBean类文件：MetalCikisIslemleriBean $ 1和MetalCikisIslemleriBean ..

EDIT＆amp;解： Tomcat正在缓存该项目的war文件。当我从Tomcat的缓存中删除战争时（在Netbeans：服务面板 - 服务器 - Tomcat - Web应用程序中）问题得到了解决。谢谢大家。

2 个答案:

答案 0 :(得分：2)

我认为com.turktrust.iab.ebs.backingbeans.MetalCikisIslemleriBean已被SVN中的任何其他人更改，因此您获得了java.io.InvalidClassException。

问题是，您是否在任何本地存储上存储了此类的旧版本的数据（您的会话？），现在您正尝试使用 new <来加载它/ em>版本。根据班级的变化，这是不可能的。

最简单的解决方案是从本地存储（可能是工作目录）中删除会话数据 - 但要小心，因为您将丢失存储在用户会话中的所有信息。

<强>更新

当tomcat关闭时，尝试从temp和work目录中删除所有文件

答案 1 :(得分：0)

似乎Tomcat在关闭一段时间后仍保留了编译类的先前版本。之后，您部署了重新编译的应用程序更新版本。当Tomcat想要恢复持久化会话时，它无法执行此操作，因为他从serialVersionUID注意到该类已更改。如果旧的持久会话中没有重要数据，我建议您删除SESSIONS.ser文件来删除它。我想它可能在work目录中。
