JAR包放在WEB-INF/lib子目录报ClassNotFoundException解决方案

在没有使用maven的Java



在web.xml配置了spring的监听器：

    <context-param>         <param-name>contextConfigLocation</param-name>         <param-value>classpath:beans.xml</param-value>     </context-param>     <listener>         <listener-class>             org.springframework.web.context.ContextLoaderListener         </listener-class>     </listener>
