java - 无法在 Struts 中加载配置

Question

我正在尝试在在线考试中实现 STRUTS Spring 和 HIBERNATE 集成。使用 apache tomcat 7.0.42 在 Eclipse Kepler 中运行项目时，它会抛出以下错误

**HTTP Status 404 - /OnlineExam/registration.jsp**
**Description:**The requested resource is not available.

在控制台日志中，出现以下内容，

我认为您缺少“struts2-spring-plugin-2.1.6.jar”文件，请在类路径中检查它
