请帮助解决此问题。

Answer 1

IncompatibleClassChangeError意味着JVM正在获得有关某些类的矛盾信息。当您针对某个版本的类或接口编译某些代码，然后在运行时使用该类/接口的不同版本时，通常会发生这种情况。当JVM检查类和方法签名是否匹配时，问题在运行时被选中。

在这种情况下，“实现类”消息似乎表示更改的类不再实现它最初执行的某个接口。（可能包名已更改。）

在日志文件的某处，应该有一条消息可以命名导致问题的类，但是您提供的堆栈跟踪的删除版本不会。

我会说他们有两种可能性。一个是你的构建方式存在问题，而且你没有重新编译应该重新编译的东西。另一种可能性是你的WAR文件中存在不一致的JAR混合;例如你在某种程度上混合了不同版本的Spring的JAR。

您明确设置了spring-hibernate3依赖项：

<dependency>
  <groupId>org.springframework</groupId>
  <artifactId>spring-hibernate3</artifactId>
<version>2.0.8</version>

这是你获得例外的豆子并非巧合。

你不应该这样做;有没有理由你没有使用你正在使用的相同版本Spring的spring-orm？我已经有一段时间没有设置明确的hibernate3依赖。
