Question

我使用Spring JDBC模板开发了一个DAO war项目，该模板中包含applicationContext.xml并导出为jar。然后，我创建了另一个jar项目，该项目导入了DAO jar，但它抛出了堆栈跟踪。

Exception in thread "main" org.springframework.beans.factory.CannotLoadBeanClassException: Cannot find class [com.breeze.bis.dao.service.jdbcTemplate] for bean with name 'genericDaoImpl' defined in class path resource [applicationContext.xml]; nested exception is java.lang.ClassNotFoundException: com.breeze.bis.dao.service.jdbcTemplate

DAO jar作为库导入，在构建路径中需要项目以及eclipse中的order和export选项卡，但是由于jar由提及类组成，因此URLClassLoader无法加载类。

请帮忙。

感谢。
