index.jsp在webContent。 loginform.jsp位于webContent-＆gt; web-Inf - ＆gt; Views

Answer 1

您的dispatcherServlet将URL：/forms/*映射到spring servlet。

您正在申请以下网址：/SBC/loginform.html

此请求永远不会转到spring servlet。您必须访问：/{your app context}/forms/loginform.html才能转到映射的spring url。您的应用上下文似乎是“SBC”，因此它类似于：/SBC/forms/loginform.html

另一种方法是将Servlet映射更改为：

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

这样，应用程序上下文/SBC/*上的每个请求都将路由到spring servlet。使用此配置，您应该能够使用以下命令访问控制器：/SBC/loginform.html
