Question

我从start.spring.io下载了我的项目，文件夹结构如图片所示，无法将special-title.html页面添加到home.jsp页面。

我使用以下命令进行集成。

<jsp:include page="/WEB-INF/jsp/special-title.html"></jsp:include>

<jsp:include page="../WEB-INF/jsp/special-title.html"></jsp:include>

<jsp:include page="${pageContext.request.contextPath}/WEB-INF/jsp/special-title.html"></jsp:include>

但是，我无法运行这些命令。我在哪里犯错了？

首先将extension NSAttributedString { func sizeFittingWidth(_ w: CGFloat) -> CGSize { let textStorage = NSTextStorage(attributedString: self) let size = CGSize(width: w, height: CGFloat.greatestFiniteMagnitude) let boundingRect = CGRect(origin: .zero, size: size) let textContainer = NSTextContainer(size: size) textContainer.lineFragmentPadding = 0 let layoutManager = NSLayoutManager() layoutManager.addTextContainer(textContainer) textStorage.addLayoutManager(layoutManager) layoutManager.glyphRange(forBoundingRect: boundingRect, in: textContainer) let rect = layoutManager.usedRect(for: textContainer) return rect.integral.size } }从special-title.html移到WEB-INF下的templates文件夹中。

然后在jsp文件中尝试添加行resources而不是<%@ include file="resources/templates/special-title.html"%>

要将html作为jsp运行，您可以做一件事。像这样在<jsp:include page="/WEB-INF/jsp/special-title.html"></jsp:include>内写一个web.xml

WEB-INF

如何将外部页面添加到文件jsp？
