Spring MVC Tiles jsp页面无法正确加载答案

【问题标题】：Spring MVC Tiles jsp page not load properlySpring MVC Tiles jsp页面无法正确加载
【发布时间】：2014-07-22 16:27:16
【问题描述】：

我正在使用 Tiles 开发一个 Spring MVC 项目。当我运行应用程序时，我没有收到任何错误。但是 jsp 页面未正确加载，如下所示 p>

当我查看此页面的源代码时，我可以看到 layout.jsp 和 home.jsp 代码已加载。但正如您在上面看到的，该页面仅显示 jsp 标记。

如何解决这个问题？提前谢谢

【解决方案1】：

问题在于 web.xml 中带有 servlet 映射的磁贴配置

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

当我使用/* 时，home.jsp 会正确加载磁贴配置，但没有 css 和图像。

在/的情况下，home.jsp不加载tile配置，只显示仅在home.jsp中定义的代码

我找到了解决方案here 作为使用 tukey 编写 url 的 Spring 示例 (https://src.springframework.org/svn/...ebapp/WEB-INF/ ) 来解决问题，我添加了使用 /* url 映射的过滤器和过滤器映射，并将 appServlet url 模式更改为 /

web.xml

 <!-- Reads request input using UTF-8 encoding -->

    <filter>
            <filter-name>characterEncodingFilter</filter-name>
            <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
            <init-param>
                <param-name>encoding</param-name>
                <param-value>UTF-8</param-value>
            </init-param>
            <init-param>
                <param-name>forceEncoding</param-name>
                <param-value>true</param-value>
            </init-param>
        </filter>

        <filter-mapping>
            <filter-name>characterEncodingFilter</filter-name>
            <url-pattern>/*</url-pattern>
        </filter-mapping>

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

我从web.xml删除了这个

<welcome-file-list>
        <welcome-file>/WEB-INF/views/home.jsp</welcome-file>
</welcome-file-list>

最后我改变了 servlet-context.xml

<!-- Forwards requests to the "/" resource to the "home" view -->
    <mvc:view-controller path="/" view-name="home" />

然后一切开始工作。希望这可以帮助另一个 * 用户
