我试图测试 Spring MVC 并编写了以下代码:

<display-name>To do List</display-name>
<welcome-file-list>

org.springframework.web.servlet.DispatcherServlet
</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/todo-servlet.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>/spring-mvc/*</url-pattern>
</servlet-mapping>
</web-app>
todo-servlet.xml:

}
}

最佳答案
如下更改您的 web.xml:
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/todo-servlet.xml</param-value>
</context-param>
<servlet>
<servlet-name>dispatcher</servlet-name>
<servlet-class>
org.springframework.web.servlet.DispatcherServlet
</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value></param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>/your-mapping/*</url-pattern>
</servlet-mapping>
<listener>
<listenerclass>
org.springframework.web.context.ContextLoaderListener
</listener-class>
</listener>
