堆栈跟踪之前的长错误消息（为了清晰起见重新格式化）解释了该问题：java.io.IOException: org.xml.sax.SAXParseExceptionpublicId: file:/home/vladimir/Downloads/glassfish-5.0/glassfish5/glassfish/lib/schemas/web-app_4_0.xsd;lineNumber: 8; columnNumber: 27; Deployment descriptor file  in archive [web_war_exploded].  TargetNamespace.1: Expecting namespace'http://java.sun.com/xml/ns/javaee', but the target namespace of the schema document is 'http://xmlns.jcp.org/xml/ns/javaee'.因此，Glassfish 架构定义 ( web-app_4_0.xsd ) 中指定的命名空间与您在应用程序的部署描述符 ( WEB-INF/web.xml ) 中提供的命名空间不匹配。这是 Glassfish 的web-app_4_0.xsd的顶级内容：<?xml version="1.0" encoding="UTF-8"?><xsd:schema xmlns="http://www.w3.org/2001/XMLSchema"            targetNamespace="http://xmlns.jcp.org/xml/ns/javaee"            xmlns:javaee="http://xmlns.jcp.org/xml/ns/javaee"            xmlns:xsd="http://www.w3.org/2001/XMLSchema"            elementFormDefault="qualified"            attributeFormDefault="unqualified"            version="4.0">...</xsd:schema>targetNamespace请注意，为和指定的值xmlns:javaee是您应该在应用程序的web.xml"http://xmlns.jcp.org/xml/ns/javaee"中指定的值，而不是。修理："http://java.sun.com/xml/ns/javaee"停止玻璃鱼在应用程序的web.xml中，将所有出现的 替换http://java.sun.com/xml/ns/javaee为http://xmlns.jcp.org/xml/ns/javaee。清理、构建和重新部署您的应用程序。重新启动 Glassfish 服务器。
