关于我们身体.jsp你好
在我的上述代码中,如果我尝试使用(域名)/示例/aboutus.do 访问该应用程序,它会给出 500 错误。谁能帮我弄清楚这一点?
错误消息显示:
无法创建路径/aboutus的操作实例是错误 显示
这意味着 Struts 无法将 struts-config.xml 中配置的操作类实例化为 java.com.mbest.core.action.AboutUsAction
。您的类名为 java.com.mindbest.core.action.AboutUsAction
。所以很明显,你得到这个错误。
另请注意,java 包是为 JRE 的核心类保留的。我什至惊讶于您的编译器接受编译这样的类,或者至少不会发出任何警告。不要把你的类放在一个java.**
包里。
