我得到这个错误，当我运行我的Java应用程序我Hibernate一起工作：

，我加入ASM的所有罐子

当提供的库版本没有所需的类时会发生这种情况。虽然没有一般的解决方法，但是您可以尝试使用这种适合我的方法。

您只需要从休眠中正确排除ASM库并单独包含它。看起来很模糊，但看看工作pom.xml中的片段。这种方法背后的意图是包含项目中某些其他第三库可能需要的更高版本的相关库。

包括hibernate实体管理器我正在使用以下代码。

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

在这里，我明确地排除从休眠实体列入经理ASM和它旁边，我分别包括它

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

和性能。这些版本选择适用于最新项目中的我。

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

希望，这可以解决您的问题。
