請幫助解決這個問題。

Answer 1

明確設置彈簧Hibernate3的依賴性：

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

這不是巧合，這是你得到的例外豆。

你不應該這樣做;你有沒有使用Spring的同一版本的spring-orm的原因？我有一段時間沒有設置明確的hibernate3依賴關係。

Answer 2

IncompatibleClassChangeError意味着JVM獲得有關某個類的相互矛盾的信息。當您針對一個類或接口的某個版本編譯某些代碼時，通常會發生這種情況，但在運行時使用該類/接口的不同版本。當JVM檢查類和方法簽名匹配時，運行時就會遇到問題。

在這種情況下，「實現類」消息似乎是說改變的類不再實現它原來的一些接口。 （也許程序包名稱已更改）

在日誌文件的某處應該有一個消息，指出導致問題的類，但是您提供的堆棧跟蹤的expurgated版本沒有。

我會說他們是兩種可能性。一個是，你在構建你的構建方式時遇到了問題，並且你沒有重新編譯應該重新編譯的東西。另一種可能性是你的WAR文件中有不一致的JAR混合;例如你在某種程度上混合了不同版本的Spring的JAR。
