尽管我知道JSP支持中存在一些限制，但是我想在Spring Boot Web应用程序中将JSP与JSTL标签一起使用。
我的JSP文件的摘录：
<%@ page pageEncoding="UTF-8"%> <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %> <%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions"%> ... <c:catch var="ex"> <c:if test="${!fn:contains(param.template,'../') && !fn:startsWith(param.template,'/')}"> <c:import url= ...
因此，我将以下依赖项添加到pom.xml：
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-tomcat</artifactId> </dependency> <dependency> <groupId>org.apache.tomcat.embed</groupId> <artifactId>tomcat-embed-jasper</artifactId> <scope>provided</scope> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>jstl</artifactId> </dependency>
但是，如果访问jsp，则会引发异常：

有人知道解决方案或解决方法吗？
环境：
我不需要使用Thymeleaf的替代解决方案。
编辑：
重现步骤：
git clone https://github.com/k-tamura/easybuggy4sb.git
cd easybuggy4sb
将以下属性添加到src / main / resources / application.properties中（为了避免启动期间出现异常）：
server.tomcat.additional-tld-skip-patterns=*.jar
将test.jsp文件添加到src / main / webapp中：
<%@ page pageEncoding="UTF-8"%>
<%@ taglib prefix=”c” uri="http://java.sun.com/jsp/jstl/core” %>
mvn spring-boot:run
There was an unexpected error (type=Internal Server Error, status=500).
The absolute uri: [http://java.sun.com/jsp/jstl/core] cannot be resolved in either web.xml or the jar files deployed with this application
此问题是由引起的server.tomcat.additional-tld-skip-patterns=*.jar。我将结束这个问题。
