java - 在 glassfish 服务器中运行项目时出现 web.xml SAXParseException 错误

Question

当我在 IntelliJ 上运行项目时，出现 java.io.IOException: org.xml.sax.SAXParseException 错误。

我找不到问题所在。有人可以帮我解决这个错误吗？

web.xml

<?xml version="1.0" encoding="UTF-8"?>

<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee
         http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
         version="3.1">
</web-app>

持久性.xml

<persistence xmlns="http://xmlns.jcp.org/xml/ns/persistence"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence
             http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd"
             version="2.1">

    <persistence-unit name="aquadinePU" transaction-type="RESOURCE_LOCAL">

        <properties>
            <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect" />
            <property name="javax.persistence.jdbc.driver" value="com.mysql.jdbc.Driver" />
            <property name="javax.persistence.jdbc.url" value="jdbc:mysql://localhost:3306/aquadine?autoReconnect=true&amp;useSSL=false&amp;allowPublicKeyRetrieval=true" />
            <property name="hibernate.hbm2ddl.auto" value="update"/>
            <property name="javax.persistence.jdbc.user" value="root" />
            <property name="javax.persistence.jdbc.password" value="ruta" />
            <property name="hibernate.show_sql" value="true"/>
        </properties>
    </persistence-unit>

</persistence>

web.xml的错误如下:

java.io.IOException: org.xml.sax.SAXParseExceptionpublicId: http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd; lineNumber: 1; columnNumber: 1; Deployment descriptor file WEB-INF/web.xml in archive [aquadine-jee].  Premature end of file.

persistence.xml的错误如下:

java.io.IOException: org.xml.sax.SAXParseExceptionpublicId: http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd; lineNumber: 1; columnNumber: 1; Deployment descriptor file META-INF/persistence.xml in archive [classes].  Premature end of file.

几天后我们也开始收到此错误。 URI:

 http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd 

返回 SAX 解析器无法处理的状态代码 301。

我们的修补程序是将 web.xml 中的架构位置更改为新文件:

xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://www.oracle.com/webfolder/technetwork/jsc/xml/ns/javaee/web-app_3_1.xsd
