Question

我的基本Spring MVC Web应用程序不起作用。我创建了Simple Spring Web Maven项目并删除了不必要的代码来简化它。然后，我添加了Controller实现，并在我最近阅读的书中注释了它。我从book和我刚刚创建的应用程序部署了一个示例应用程序。示例应用程序正常工作 - 我没有。当我尝试访问URL ... localhost ... / app-name / start / basic / show Tomcat Server显示404错误。这是我的代码：

spring.app包中的BasicController

@Controller
@RequestMapping("/basic")
public class BasicController{

    @RequestMapping("/show")
    public ModelAndView handleRequest(HttpServletRequest arg0,
            HttpServletResponse arg1) throws Exception {

        Map < String, String > modelData = new HashMap < String, String >();
        modelData.put("message", "Hello World!");

        return new ModelAndView("showMessage", modelData);
    }

}

App / src / main / webapp / WEB-INF / mvc-config.xml文件：

WEB-INF / view目录中的showMessage.jsp：

<!DOCTYPE html>

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>

<html>
    <head>
        <meta charset="utf-8">
        <title>Welcome</title>
    </head> 
    <body>
        <h2>${message}</h2>
    </body>
</html>

我试图解决这个问题，但所有内容都像示例应用程序一样实现，所以我不知道它为什么会失败。

我的痕迹，当我选择“在服务器上运行”并且我只部署了这个应用程序时：

好吧，假设我通过创建Spring MVC Project而不是Simple Spring Web Maven Project来解决这个问题。现在一切正常。

Answer 1

根据您的日志

您的应用未获得部署。我从您的日志中获得了线索

INFO: Deploying

当您阅读INFO: Deploying

时

它没有说明你的应用程序是什么＆＃34; / App＆＃34;
