本文解决了一个SSH项目启动时报出的java.lang.NoClassDefFoundError错误，问题出现在org.springframework.dao.support.PersistenceExceptionTranslator类未找到，通过添加spring-dao.jar包解决了该问题。

java.lang.NoClassDefFoundError: org/springframework/dao/support/PersistenceExcep解决办法

前段时间自己建了一个ssh项目，启动的时候报错：

org.springframework.beans.factory.CannotLoadBeanClassException: Error loading class [org.springframework.orm.hibernate3.LocalSessionFactoryBean] for bean with name 'sessionFactory' defined in ServletContext resource [/WEB-INF/applicationContext.xml]: problem with class file or dependent class; nested exception is java.lang.NoClassDefFoundError: org/springframework/dao/support/PersistenceExceptionTranslator
at org.springframework.beans.factory.support.AbstractBeanFactory.resolveBeanClass(AbstractBeanFactory.java:1141)
……

Caused by: java.lang.NoClassDefFoundError: org/springframework/dao/support/PersistenceExceptionTranslator

……

严重: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener
org.springframework.beans.factory.CannotLoadBeanClassException: Error loading class [org.springframework.orm.hibernate3.LocalSessionFactoryBean] for bean with name 'sessionFactory' defined in ServletContext resource [/WEB-INF/applicationContext.xml]: problem with class file or dependent class; nested exception is java.lang.NoClassDefFoundError: org/springframework/dao/support/PersistenceExceptionTranslator
at org.springframework.beans.factory.support.AbstractBeanFactory.resolveBeanClass(AbstractBeanFactory.java:1141)

找不到class类，首先判定是少导了jar包，再看org/springframework/dao/support/PersistenceExceptionTranslator，就想是不是没有导入spring-dao.jar的关系，将此jar包导入，运行tomcat，成功！
