JSP页面中的以下语句在第一次equals出现时遇到错误。什么原因以及我们如何解决这个问题。请尽快纠正我
${(fn:length(updateStock.todayDimensionStones)==i.count) && (!DimensionStones.status.equals('New')||!DimensionStones.isInspected.equals('No'))}
页面已成功加载。但在 JBOSS VISUAL STUDIO 编辑器中显示

column 86.
Was expecting one of:

最佳答案
在 JSP EL 中，==(或 !=)通常用于比较字符串，而不是 .equals():
${(fn:length(updateStock.todayDimensionStones) == i.count) &&
(DimensionStones.status != 'New' || DimensionStones.isInspected != 'No')}
AFAIR，最新版本的 JSP EL 允许调用方法，但您的 IDE 可能已经过时并且不希望如此。 Eclipse 以发出根本不是错误的信号错误而闻名。信任您的应用服务器。
