當提供的庫版本沒有所需的類時會發生這種情況。雖然沒有一般的解決方法，但是您可以嘗試使用這種適合我的方法。

您只需要從休眠中正確排除ASM庫並單獨包含它。看起來很模糊，但看看工作pom.xml中的片段。這種方法背後的意圖是包含項目中某些其他第三庫可能需要的更高版本的相關庫。

包括hibernate實體管理器我正在使用以下代碼。

<dependency> 
    <groupId>org.hibernate</groupId> 
    <artifactId>hibernate-entitymanager</artifactId> 
    <version>${hibernate.version}</version> 
    <exclusions> 
     <exclusion> 
     <groupId>asm</groupId> 
     <artifactId>asm</artifactId> 
     </exclusion> 
     </exclusions> 
    </dependency> 

在這裏，我明確地排除從休眠實體列入經理ASM和它旁邊，我分別包括它

<dependency> 
     <groupId>asm</groupId> 
     <artifactId>asm</artifactId> 
     <version>${asm.version}</version> 
    </dependency> 

和性能。這些版本選擇適用於最新項目中的我。

<properties> 
      <hibernate.version>3.6.0.Final</hibernate.version> 
      <asm.version>3.3</asm.version> 
    </properties> 

希望，這可以解決您的問題。
