spring - 启动 Spring MVC 项目时出现 Tomcat 错误

标签 spring tomcat

我刚开始学习 Spring MVC。我的程序列表如下。我的 src/MySpringMVCProjects 文件夹中有一个 Controller 。我在 Controller 类中的 Exception、String 和 getParameter 行中得到多个错误标记。

Controller 

package MySpringMVCProjects;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.Controller;

public class HelloController implements Controller {
    public ModelAndView handleRequest(HttpServletRequest req,
            HttpServletResponse res) throws Exception {
        String name = req.getParameter("name");
        Map m = new HashMap();
        m.put("msg", "Hello" + name);
        ModelAndView mav = new ModelAndView("success", m);
        return mav;
    }
}

错误是什么？我该如何解决这个问题？

最佳答案

服务器似乎正常启动。

从项目结构来看，您无法编译项目:原因是您添加了源文件而不是实际的库。

您可以查看一些已经可用的教程，例如:

如果您仍然遇到任何问题，请粘贴您日志文件中的日志条目 能否请您粘贴来自 Log4j 或 slf4j 的错误。
