我正在使用Spring，并且application-context.xml具有以下定義：<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"   xmlns:util="http://www.springframework.org/schema/util"   xmlns:context="http://www.springframework.org/schema/context"   xmlns:aop="http://www.springframework.org/schema/aop"   xmlns:tx="http://www.springframework.org/schema/tx"   xmlns:p="http://www.springframework.org/schema/p"   xmlns:security="http://www.springframework.org/schema/security"   xsi:schemaLocation="   http://www.springframework.org/schema/beans    http://www.springframework.org/schema/beans/spring-beans-2.0.xsd   http://www.springframework.org/schema/util    http://www.springframework.org/schema/util/spring-util-2.0.xsd   http://www.springframework.org/schema/context   http://www.springframework.org/schema/context/spring-context-2.1.xsd   http://www.springframework.org/schema/tx   http://www.springframework.org/schema/tx/spring-tx.xsd   http://www.springframework.org/schema/aop   http://www.springframework.org/schema/aop/spring-aop-2.0.xsd   http://www.springframework.org/schema/security   http://www.springframework.org/schema/security/spring-security-2.0.xsd"   >.....當我的互聯網連接斷開時，我無法通過tomcat或碼頭運行我的應用程序。它給：[main] WARN  org.springframework.beans.factory.xml.XmlBeanDefinitionReader - Ignored XML validation warningorg.xml.sax.SAXParseException: schema_reference.4: Failed to read schema document '/spring-beans-2.0.xsd', because 1) could not find the document; 2) the document could not be read; 3) the root element of the document is not <xsd:schema>.    at com.sun.org.apache.xerces.internal.util.ErrorHandlerWrapper.createSAXParseException(ErrorHandlerWrapper.java:195)有什么建議如何解決嗎？
