我正在使用spring3.1.1 + hibernate3.6.0 + tomcat7.0.29 + mysql5.5进行Java Web开发,但是在服务器上运行后,Eclipse提示
HTTP Status 500 - Handler processing failed; nested exception is java.lang.NoClassDefFoundError: org/springframework/orm/hibernate3/support/HibernateDaoSupport
详细如下,
类型例外报告
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

我不明白为什么它告诉我没有hibernatedaosupport,并且已经将其导入到项目中的引用库和web-inf / lib中。
我导入的软件包如下
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
以及与事务处理有关的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>
最佳答案
NoClassDefFoundError
意味着类加载器找不到org.springframework.orm.hibernate3.support.HibernateDaoSupport
依赖的类。并不是说HibernateDaoSupport
本身不丢失。查找缺少哪个依赖项的最佳方法是查看 HibernateDaoSupport
的import部分
看来您的类路径中缺少org.springframework.dao
库。
