Spring Boot-绝对 uri : http://java. sun.com/jsp/jSTL/core 无法在 web.xml 或 jar 文件中解析

Question

我已经找到了解决方案。 This is the closest it gets和 This 。这些都不起作用。我得到以下异常。我正在使用 Spring Boot 。我将它作为 Spring boot 应用程序运行。不在 Tomcat 内部。

org.apache.jasper.JasperException: /common/taglibs.jsp(9,62) PWC6188: 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

在我看来，一切都已就位。我仍然收到错误。我查看了 Maven 依赖项。我可以看到 jSTL-1.2.jar

Answer 1

您正在尝试使用 Jetty 作为嵌入式容器，并且 as stated in the Spring Boot documentation ，嵌入式 Jetty 不支持 JSP:

When running a Spring Boot application that uses an embedded servlet container (and is packaged as an executable archive), there are some limitations in the JSP support.

• With Tomcat it should work if you use war packaging, i.e. an executable war will work, and will also be deployable to a standard container (not limited to, but including Tomcat). An executable jar will not work because of a hard coded file pattern in Tomcat.
• Jetty does not currently work as an embedded container with JSPs.
• Undertow does not support JSPs.

There is a JSP sample so you can see how to set things up.
