Spring MVC - 在名为'DefaultServlet'的DispatcherServlet中没有找到具有URI [/ webstore /]的HTTP请求的映射

我跟着“Spring MVC初学者指南”一书，并且遇到了似乎请求映射问题。Spring MVC - 在名为'DefaultServlet'的DispatcherServlet中没有找到具有URI [/ webstore /]的HTTP请求的映射

我已经看到，并试图在其他类似的堆栈溢出问题，以下解决方案：

改变“的url-pattern”自/至/ *
改变两个URL模式和参数在RequestMapping注释为 “/欢迎”
加入<mvc:default-servlet-handler/>到DefaultServlet-servlet.xml中
改变的url-pattern为 “/ WEB-INF/JSP/*”

我有下面的代码：

目录结构：

enter image description here

HomeController.java

package webstore; 

import org.springframework.stereotype.Controller; 
import org.springframework.ui.Model; 
import org.springframework.web.bind.annotation.RequestMapping; 

@Controller 
public class HomeController { 

    @RequestMapping(value="/") 
    public String welcome(Model model) { 
     model.addAttribute("greeting", "Welcome to Web Store!"); 
     model.addAttribute("tagline", "The one and only amazing webstore!"); 
     return "welcome"; 
    } 

}

的welcome.jsp

当你建立你的WAR文件，什么** **确切名称是否得到产生的？另外，如果您设置了'/*'，那么在使用URL“http：// localhost：8080/webstore /'调用服务时会出现什么错误？ – 2015-02-12 08:16:31

我该如何检查？我在我的tomcat服务器上grep了所有的.war文件，但是我只找到了一个sample.war文件。这是否意味着.war，因为我的项目没有建成？我正在使用的IDE是Spring Tool Suite，按照我所遵循的“新手指南”教程中的建议，但如果需要，我也可以使用IntelliJ。 – 2015-02-12 08:30:55

您的问题似乎与组件扫描，您正在扫描错误的软件包。控制器位于网络存储器封装，所以在你的servlet配置改变：

<context:component-scan base-package="webstore" />

或移动您的控制器来com.packt.webstore包。

当您的应用程序正在部署时，您应该在日志中看到哪些url映射已被注册，然后您将知道此修复是否有效。

这是问题所在。不知怎的，这个包被搞砸了。我用合适的命名删除并重新实现了它，匹配 base-package属性和完整的包名称（com.packt.webstore），现在运行。谢谢，很好的接收。 – 2015-02-12 09:18:27

在web.xml中尝试改变

<servlet> 
    <servlet-name>DefaultServlet</servlet-name> 
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> 

</servlet>

到

<servlet> 
    <servlet-name>DefaultServlet</servlet-name> 
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> 
    <init-param> 
     <param-name>contextConfigLocation</param-name> 
     <param-value>/WEB-INF/DefaultServlet-servlet.xml</param-value> 
    </init-param> 
    <load-on-startup>1</load-on-startup> 
</servlet>

尝试了这一点，不幸的是仍然得到了同样的错误：在名为'DefaultServlet'的DispatcherServlet中没有找到具有URI [/ webstore /]的HTTP请求的映射 – 2015-02-12 08:57:47
