【中文标题】Spring 4 MVC，警告：在 DispatcherServlet 中找不到带有 URI 的 HTTP 请求的映射，名称为 [...] 和 HTTP 404 错误【英文标题】：Spring 4 MVC , WARNING: No mapping found for HTTP request with URI in DispatcherServlet with name [...] & HTTP 404 Error 【发布时间】：2014-08-03 19:17:44 【问题描述】：我的项目突然崩溃了，dispatcher servlet 无法转发到我的视图，我开始初步获取
警告：在 Disp 中找不到带有 URI [/thedallasapp_poc/] 的 HTTP 请求的映射 atcherServlet 名称为 'mvc_dispatcher' & 浏览器中出现 404 错误。
在更改设置后，我在日志中没有收到 error.warning，但我收到了 404 错误。
这是我的项目设置：
Java： 1.6
网络框架：
• Spring 4.0.0.RELEASE（MVC 和其他包） • Spring 安全 3.2.4.RELEASE
ORM：
• 休眠 4.1.5.Final 清理、构建、编译、打包： • Maven
数据库：
• PostgreSQL
网络服务器： Apache Tomcat 7.0
这是我的 pom.xml：

通过 Eclipse 部署：
我通过 Eclipse 部署到 Tomcat，右键单击我的项目，选择 Run As，选择 Tomcatv7.0 ，选择 Finish...
结果：
应用程序在日志中没有错误/异常启动，但我在浏览器中收到 404 错误和此警告：
警告：在 Disp 中找不到带有 URI [/thedallasapp_poc/] 的 HTTP 请求的映射 名称为“mvc_dispatcher”的 atcherServlet
通过 Maven 部署：
使用命令“mvn tomcat7:deploy”或“mvn tomcat7:redeploy”进行部署
再次，应用程序启动，日志中没有错误/异常，但我在浏览器中收到 404 错误和此警告：
警告：在 Disp 中找不到带有 URI [/thedallasapp_poc/] 的 HTTP 请求的映射 名称为“mvc_dispatcher”的 atcherServlet
最后我将 web.xml Dispatcher servlet-name 映射更改为“/thedallasapp_poc*”而不是“/”：
web.xml sn-p:
<servlet>
<servlet-name>mvc_dispatcher</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>mvc_dispatcher</servlet-name>
<url-pattern>/thedallasapp_poc*</url-pattern>
</servlet-mapping>
因此我也将 HomeController 从 @RequestMapping(value="/") 更改为 @RequestMapping(value="/thedallasapp_poc")
@控制器 公共类 HomeControler
public HomeControler()
super();
// TODO Auto-generated constructor stub
/* serves the login landing/home page view */
@RequestMapping(value="/thedallasapp_poc")
public ModelAndView serveLanding(HttpSession session)
ModelAndView model = new ModelAndView();
model.setViewName("login");
Authentication auth = SecurityContextHolder.getContext().getAuthentication();
//check if isRememberMeAuthenticated cookie is true from previous login
System.out.println("Class HomeControler, String serveLanding(), isRememberMeAuthenticated():"+isRememberMeAuthenticated());
if (isRememberMeAuthenticated()!=false && auth.isAuthenticated()!=false)
session.setAttribute("isRememberMeAuthenticated", true);
return model;
//结束 HomeControler
然后我使用 Maven "mvn clean package" 重建了我的项目并再次启动了该项目。
结果： 我不再收到警告，但我仍然在浏览器中收到 404 错误，实际上我更喜欢 DispatcherServlet 映射的“/”映射。
非常感谢任何深思熟虑的建议/帮助，因为我在最后期限内。
谢谢
【问题讨论】：
你的应用有上下文路径吗？ 为什么不扫描这个包<context:component-scan base-package="com.hitachi.thedallasapp_poc.Category"/>
上面一行将扫描com.hitachi.thedallasapp_poc.Category包内所有可用的组件
它不会扫描com.hitachi.thedallasapp_poc包内的组件。
同样，我可以看到你所有的 component scan 指的是 sub packages 在 com.hitachi.thedallasapp_poc 主包中
但未扫描主要包组件。
所以包含该行
<context:component-scan base-package="com.hitachi.thedallasapp_poc"/>
在你的 spring 配置文件中扫描这个包中的所有组件。
因此您的控制器会被 Spring 扫描和检测到。
【讨论】：
我通过命名每个包来引用所有包：<context:component-scan base-package="com.hitachi.thedallasapp_poc.Category" /> <context:component-scan base-package="com.hitachi.thedallasapp_poc.location" /> <context:component-scan base-package="com.hitachi.thedallasapp_poc.messaging" /> <context:component-scan base-package="com.hitachi.thedallasapp_poc.userprofile" /> <context:component-scan base-package="com.hitachi.thedallasapp_poc.test" />，这相当于只使用基本包：<context:component-scan base-package="com.hitachi.thedallasapp_poc" />，这是正确的。谢谢
嘿，您的 HomeController 类在 com.hitachi.thedallasapp_poc 包中，但是对其所有子包进行组件扫描无助于识别此控制器，您甚至必须包含此包以用于组件-扫描...希望你明白了..有任何疑问吗？以上是关于Spring 4 MVC，警告：在 DispatcherServlet 中找不到带有 URI 的 HTTP 请求的映射，名称为 [...] 和 HTTP 404 错误的主要内容，如果未能解决你的问题，请参考以下文章
