WARN PageNotFound：找不到包含URI

Question

我正在尝试构建一个示例mvc项目，我遇到了这个问题。当我打电话给 / products url时，样式工作正常但是当我尝试调用 / products / viewProducts / {productId} url时，样式没有添加到此呼叫。这是在调用第二个URL时捕获的图像 Image2

请帮我找到我实际上做错的地方？ 以下是项目详情。

Answer 1

尝试使用以下url-pattern：

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

Answer 2

在您的JSP中，您在哪里包含引导程序文件？你的项目中有bootstrap文件吗？如果没有，那么在JSP的顶部添加这些：

<link rel="stylesheet"
href="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">
<script
src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
<script
src="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>

这些将在JSP中包含bootstrap lib（和jquery lib），然后它将显示 styles

@Pavan如果您真的不想在每个jsp中编写包含内容的内容，那么您必须在部署描述符（您的web.xml文件）中配置JSP，如下所示：

<jsp-config>
<jsp-property-group>
<url-pattern>*.jsp</url-pattern>
<url-pattern>*.jspf</url-pattern>
<include-prelude>/WEB-INF/jsp/base.jspf</include-prelude>
<trim-directive-whitespaces>true</trim-directive-whitespaces>
</jsp-property-group>
</jsp-config>

现在，如果您看到，我将此行放在上面的配置<include-prelude>/WEB-INF/jsp/base.jspf</include-prelude>中 部署描述符中的标记告诉了 容器在每个属于的JSP的开头包含/WEB-INF/jsp/base.jspf文件 这个属性组。这对于定义公共变量，标记库声明或其他变量很有用 应该对组中的所有JSP可用的资源。同样，一个标签 定义要包含在组中每个JSP末尾的文件。您可以更多地使用这两个标签 而不是一次在一个JSP组中。例如，您可以创建header.jspf和footer.jspf文件 分别包括每个JSP的开头和结尾。

现在base.jspf包含什么？这个：

<%@ taglib prefix="spring" uri="http://www.springframework.org/tags"%>
<%@include file="/WEB-INF/views/template/header.jsp"%>
<%@include file="/WEB-INF/views/template/footer.jsp"%>
<link rel="stylesheet"
href="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">
<script
src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js">   </script>
<script
src="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"> </script>

但是我不知道你是否会添加引导线是否会被JSP拾取。但试试吧。如果它们不起作用那么就假设我从未回答过这个问题。抱歉。哦，确保这个base.jspf位于/WEB-INF/jsp/然后所有的JSP文件都在该路径下。

警告：如果你这样做，你必须移动你的jsps一点才能工作。

我希望这会有所帮助，我希望我没有进一步困惑你或让你的工作更加努力！
