我的 Controller 类有问题:我使用 maven 创建项目，并添加 hibernate 和 Spring 的依赖项。当我启动应用程序时，我可以从 servlet 进入第一页，但是当我调用任何方法时，我得到 404。我尝试了很多解决方案，但没有人工作，我使用 Web 逻辑服务器，为此有一些特殊的配置服务器？在项目中这是我的实际情况:
AppController.java
@Controller
@RequestMapping("/")
public class AppController {
@RequestMapping(value = "/two", method = RequestMethod.GET)
public String two() {
System.out.println("work?");
return "newFile";
}
}
我也尝试使用 ModelAndView
注册.jsp

在JSP和方法中，我尝试使用/和不使用/来编写调用方法的值，但结果是相同的。有人可以帮助我吗？
最佳答案
如果我正确理解了问题，那么您拥有新的 Controller 组件和请求映射，应在表单提交时调用它们。
我在 xml 配置中看到以下问题
您没有在web.xml中使用spring DispatcherServlet。该类负责处理并处理请求并转发给适当的 Controller
您正在使用 com.reply.servlet.LDSServlet 类在 web.xml 中定义映射。 LDSServlet 类会是什么样子？
基本上，DispatcherServlet 将处理配置( Controller 类和请求映射)，并在请求到达时使用它来选择适当的 Controller 。
编辑:
您应该在表单操作中包含context-path。
