使用注解的基本Spring Web MVC应用程序

[英]Basic Spring Web MVC Application using annotation

问题描述

我的基本Spring MVC Web应用程序无法正常工作。 我创建了Simple Spring Web Maven Project，并删除了不必要的代码以简化它。 然后，我添加了Controller实现，并像最近读过的书中一样对其进行了注释。 我从本书和刚刚创建的应用程序中部署了一个示例应用程序。 示例应用程序正常运行-我的不是。 当我尝试访问URL ... localhost ... / app-name / start / basic / show Tomcat服务器显示404错误。 有我的代码：

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：

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

我正在尝试解决此问题，但是一切都像在示例应用程序中那样实现，所以我不知道为什么它会失败。

我的踪迹，当我选择“在服务器上运行”并且仅部署了该应用程序时：

好的，假设我通过创建Spring MVC Project而不是Simple Spring Web Maven Project来解决此问题。 现在一切正常。

根据你的日志

您的应用未部署。我从您的日志中得到了一个线索

INFO: Deploying

当您阅读有关INFO: Deploying

它没有说明您的应用程序为“ / App”
