Question

我正致力于在遗留应用程序中实现Spring Session。我按照Spring文档来实现会话库，一切似乎都运行良好，除了....

通过sitemesh在每个页面上都有一个UI元素。此UI元素检查会话中的对象以查看是否应显示该对象。通过sitemesh装饰器从会话中检索对象时，该对象为null。当我通过控制器或主内容JSP访问同一个对象时，会填充该对象，一切正常。

换句话说：

Web request -> tomcat -> controller -> jsp -> jstl -> session object = ok

然后继续渲染sitemesh decorator adds main.jsp -> jstl -> same session object is null

我认为这必须是配置问题。我可以确认，当我注释掉springSessionRepositoryFilter页面呈现正确时，但是我没有使用spring会话并点击我的redis服务器。如果有人有任何想法，我会非常感激。谢谢！我的web.xml看起来像这样。

在您正在使用的地方，这可能会有所帮助：

<filter>
    <description>sitemesh-filter</description>
    <filter-name>MyApplicationSitemeshFilter</filter-name>
    <filter-class>com.opensymphony.module.sitemesh.filter.PageFilter</filter-class>
</filter>
<filter-mapping>
    <filter-name>MyApplicationSitemeshFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

尝试将其替换为此：

   <filter>
        <filter-name>sitemesh</filter-name>
        <filter-class>com.opensymphony.sitemesh.webapp.SiteMeshFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>sitemesh</filter-name>
        <url-pattern>/*</url-pattern>
        <dispatcher>REQUEST</dispatcher>
        <dispatcher>FORWARD</dispatcher>
        <dispatcher>ERROR</dispatcher>
    </filter-mapping>
