在tomcat 7中初始化应用程序时，Spring CannotLoadBeanClassException

Question

在Tomcat 7启动中初始化bean时遇到问题。 我最怀疑的是它的定义为null。

applicationContext.xml部分

<!-- =============================================== -->
    <!-- CXF Web Service Definition -->

        </jaxws:features>

进行mvn全新安装时，我没有收到任何错误，但是当我启动包含项目的Tomcat 7服务器时，得到以下信息：

Answer 1

根本原因是ClassNotFoundException ，缺少类es.sacnet.hdc.bsg.webservices.impl.BSGenericoCommonImpl 。
