spring - tomcat 7 上缺少变量的 JSP 错误

转载作者：行者123 更新时间：2023-12-04 18:05:42

我有一个在 tomcat 6 上运行良好的 Spring 安装，但是在尝试更新到 tomcat 7 时，我的 JSP 文件中出现了很多错误。最值得注意的是，如果一个变量不存在，它不会像以前那样计算为 null，而是会出错。这个有配置值吗？或某种测试变量是否存在的方法？每次我要求一个不存在的变量，即使只是为了测试它是空的还是空的，它都会抛出一个错误...

即

${not empty cmsPage.label} //throws an error if cmsPage.label doesn't exist. This used to resolve as false if it didn't exist...

编辑:

看来根本原因是javax.el.PropertyNotFoundException，这是有道理的。我想令我困惑的是为什么这在我更新时才开始。我们的 JSP 页面过去从不关心属性是否存在。我们有很多使用 null 检查来检查属性的旧代码，希望我没有通过所有代码来捕获 PropertyNotFoundExceptions。也许有一个配置值可以用来忽略这些？或者如果需要，检查属性是否存在的最佳方法是什么？

这是堆栈跟踪:

最佳答案

您的问题是您正在尝试使用 de.hybris.platform.cms2.model.pages.CategoryPageModel 的“label”属性。此类型没有属性“标签”。这仅适用于 de.hybris.platform.cms2.model.pages.ContentPageModel。

“pageTitle”应该已经由您的 Controller 写入。你不需要做那个检查。
