内容图文

我正在使用Java web开发,使用spring3.1.1 hibernate3.6.0 tomcat7.0.29 mysql5.5,但在我的服务器上运行后,Eclipse提示

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

并详细说明如下,
类型异常报告

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

我无法理解为什么它告诉我没有hibernatedaosupport,我已经在引用库和web-inf / lib中的项目中导入它.
我导入的包装如下,

 commons-beanutils-1.8.3.jar 
    commons-coder-1.4.jar 
    commons-io-2.3.jar 
    commons-lang-2.6.jar 
    commons-logging-1.1.1.jar 
    ezorph-1.0.6.jar 
    json-lib-2.4-jdk15.jar 
    jstl-1.2.jar 
    org.springframework.asm-3.1.1.release.jar 
    org.springframework.beans-3.1.1.release.jar 
    org.springframework.context-3.1.1.release.jar 
    org.springframework.core-3.1.1.release.jar 
    org.springframework.expression-3.1.1.release.jar 
    org.springframework.web.servlet-3.1.1.release.jar 
    org.springframework.web-3.1.1.release.jar 
    servlet-api.jar 
    antlr-2.7.6 
    c3p0-0.9.1.jar 
    commons-collections-3.1.jar 
    dom4j-1.6.1.jar 
    ehcache-1.5.0.jar 
    hibernate-jpa-2.0-api-1.0.1.final.jar 
    hibernate3.jar 
    javassist-3.12.0.ga.jar 
    jta-1.1.jar 
    mysql-connector-java-5.1.12-bin.jar 
    org.springframework.orm-3.1.1.release.jar 
    org.springframework.jdbc-3.1.1.release.jar 
    org.springframework.aop-3.1.1.release.jar 
    org.springframework.transaction-3.1.1.release.jar 
    slf4j-api-1.6.1.jar 
    slf4j-nop-1.6.1.jar 

以及与事务处理相关的applicationContext.xml的部分内容如下,

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

<tx:advice id="txAdvice" transaction-manager="transactionManager"> 
    <tx:attributes> 
        <tx:method name="get*" read-only="true" /> 
        <tx:method name="*" /> 
    </tx:attributes> 
</tx:advice> 

<aop:config> 
    <aop:pointcut id="fbPointcut" expression="bean(dbManager)" /> 
    <aop:advisor advice-ref="txAdvice" pointcut-ref="fbPointcut" /> 
</aop:config>

解决方法:

NoClassDefFoundError意味着类加载器找不到org.springframework.orm.hibernate3.support.HibernateDaoSupport所依赖的类.并不是说HibernateDaoSupport本身丢失了.找到缺少哪个依赖项的最佳方法是查看HibernateDaoSupport的导入部分

您的类路径中似乎缺少org.springframework.dao库.
