我在那个文件夹中有一个图像:src/main/resources/images/image.jpg
我尝试以不同的方式在src/main/webapp/vues/bonjour.jsp中显示前面的图像:
<%@ page language="java" contentType="text/html; charset=ISO-8859-1" isELIgnored="false"
pageEncoding="ISO-8859-1"%>

<body>
<div>
<img alt="image" src="/resources/images/image.jpg" />
<img src="/tutoriel-web-spring/resources/images/image.jpg" alt="image" />
<img src="<c:url value="/resources/images/image.jpg" />" alt="image" />
<img src="<c:url value="/images/image.jpg" />" alt="image" />
</div>
</body>
</html>
但无法显示它,只能显示备用文本。谢谢你帮助我 如果您希望能够引用图像的绝对路径,无论调用JSP使用的URL是什么,都必须使用abolute路径src=${pageContext.request.contextPath}/resources/images/image.jpg,这样src将从maven项目的上下文根开始运行。在Google Chrome中运行程序,按F12,导航到图像并查看图像的路径。如果图像路径正确且图像仍不显示,请将图像再次复制到图像文件夹中。尝试这样设置
$'id'.attr'src','/resources/images/'+imageName//动态地我通过将图像文件夹放在webapp/resources中解决了问题。图像标签是:
<img src="<c:url value="/resources/images/image.jpg" />" alt="image" />
我刚刚尝试了这个/resources/images/image.jpg alt=image/>,但没有结果。嗯,这不是我发布的内容。应该是这样的:。我有以下错误:javax.servlet.jsp.JspException无法解析为类型,无法将类型javax.servlet.jsp.PageContext解析为某个类型,并且无论出现何种错误,图像都不会显示。我已通过添加一些依赖项解决了这些错误,图像仍然没有显示。resources文件夹是否位于src/main/resources下?如果是这样,请尝试将images文件夹移动到webapp文件夹中,并将路径更改为${pageContext.request.contextPath}/images/ima通用电气公司
