java.lang.NoClassDefFoundError：org/springframework/orm/hibernate3/support/HibernateDaoSupport

Question

我正在使用Java web開發，使用spring3.1.1 + hibernate3.6.0 + tomcat7.0.29 + mysql5.5，但運行後我的服務器時，Eclipse提示說

HTTP Status 500 - Handler processing failed; nested exception is java.lang.NoClassDefFoundError:  org/springframework/orm/hibernate3/support/HibernateDaoSupport 

和具體如下， 類型異常報告

message Handler processing failed; nested exception is java.lang.NoClassDefFoundError:   org/springframework/orm/hibernate3/support/HibernateDaoSupport 

description The server encountered an internal error (Handler processing failed; nested exception is java.lang.NoClassDefFoundError:  org/springframework/orm/hibernate3/support/HibernateDaoSupport) that prevented it from fulfilling this request. 

例外

org.springframework.web.util.NestedServletException: Handler processing failed; nested exception is java.lang.NoClassDefFoundError:  org/springframework/orm/hibernate3/support/HibernateDaoSupport

我不明白爲什麼它告訴我，沒有休眠的支持，我已經在引用的庫和web-inf/lib項目中導入它。 包我已經導入如下，

與如下有關交易過程的applicationContext.xml的一部分內容，

<bean id="transactionManager"   class="org.springframework.orm.hibernate3.HibernateTransactionManager"> 
    <property name="sessionFactory" ref="sessionFactory" /> 
</bean>

    <aop:advisor advice-ref="txAdvice" pointcut-ref="fbPointcut" /> 
</aop:config> 

Answer 1

NoClassDefFoundError意味着，類裝載器不能找到一個類org.springframework.orm.hibernate3.support.HibernateDaoSupport取決於。不是HibernateDaoSupport本身缺失。找到缺失的依賴關係的最好方法是看看HibernateDaoSupport的輸入部分

看起來您在類路徑中缺少org.springframework.dao庫。

Answer 2

我認爲這是因爲你的圖書館裏有spring-orm不同版本的spring-orm類庫，它有org.springframework.orm.hibernate3.support.HibernateDaoSupport類。

將spring-orm 3.1 jar添加到您的庫。您可以在底部找到jar下載鏈接。

一般來說，如果你得到一個NoClassDefFoundError，谷歌爲具有類的jar。 Maven Central Repository是一個很好的去處。

你的spring aop，jdbc和transaction jar也是不同的版本（3.0.7而不是3.1.1）。始終使用相同版本的罐子。如果您使用不同版本的jar，應用程序可能會拋出一些錯誤。

Answer 3

14.3 Hibernate

We will start with a coverage of Hibernate 3 in a Spring environment, using it to demonstrate the approach that Spring takes towards integrating O/R mappers. This section will cover many issues in detail and show different variations of DAO implementations and transaction demarcation. Most of these patterns can be directly translated to all other supported ORM tools. The following sections in this chapter will then cover the other ORM technologies, showing briefer examples there.

Note: As of Spring 3.0, Spring requires Hibernate 3.2 or later.

來源：http://static.springsource.org/spring/docs/current/spring-framework-reference/html/orm.html#orm-hibernate

你的Hibernate版本太舊。

在重新閱讀您的問題時，您說您正在使用Hibernate 3.6，但您在依賴關係中列出了hibernate3.jar。這是什麼？
