在名为“dispatcher”的DispatcherServlet中找不到URI为[/ecommerce.mvc/]的HTTP请求的映射

servlets spring-mvc spring java

user7179261 · 技术社区 · 6 年前

我正在使用SPRING MVC创建Hello world应用程序,当我在tomcat服务器上运行应用程序时,会出现此错误。
我见过很多类似的问题被问到,但没有一个建议对我有用。

您只有一个映射是 / ,则,

<servlet-mapping>
    <servlet-name>dispatcher</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

控制器上只有一个映射:

@RequestMapping("/")

因此,要么使用 localhost:8080 仅或将请求映射更改为 @RequestMapping("/ecommerce.mvc")

笔记你在混合 @Annotation 具有 XML 配置样式。

您最好只使用一种配置样式。和 @注释 首选。

但出于教育目的,您也应该尝试XML。

您的映射配置错误:

<servlet映射>
<servlet名称(>);调度程序(&L)/servlet名称(>);
<url模式(>)/</url模式(>);
</servlet映射>

此映射需要 dispatcher servlet名称。

但调度程序配置错误:

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

这个 servlet-class 应由您的 HomeController 路径
