&引用；找不到XML架构命名空间的Spring NamespaceHandler“0”；仅在可执行jar中发生

我发现几个主题类似的问题

上下文初始化失败
org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException:来自ServletContext资源[/WEB-INF/App servlet.xml]的xml文档中的第2行无效；嵌套异常为org.xml.sax.saxpasseeption；系统ID:http://www.springframework.org/schema/beans/spring-beans-4.2.xsd; 行号：2；栏目编号：18；s4s elt字符：“xs:appinfo”和“xs:documentation”之外的架构元素中不允许使用非空白字符。

我试着应用我读过的建议，但我总是得到同样的错误

此外，在我的案例中还有一件我还没有发现的事情：下面的应用程序在Eclipse中可以完美地工作。错误只发生在可执行jar中。我的意思是，我右键点击App.java并适当地运行它。然而，如果我导出为可运行的Jar文件并用java-Jar启动它，我会得到如下所示的错误

静态主要方法：

import org.apache.catalina.startup.Tomcat;
import javax.servlet.ServletException;
import org.apache.catalina.Context;
import org.apache.catalina.LifecycleException;
import org.apache.catalina.Wrapper;


public class App6 {

       public static void main(String[] args) throws ServletException, LifecycleException {

              Tomcat tomcat = new Tomcat();
              tomcat.setPort(8080);
              tomcat.setBaseDir(".");

              Context appContext = tomcat.addWebapp(tomcat.getHost(), "","C:\\STS\\wsRestTemplate\\AuthFileUpload\\target\\classes");

              Wrapper jspServlet = appContext.createWrapper();
              jspServlet.setName("jsp");            jspServlet.setServletClass("org.apache.jasper.servlet.JspServlet");

              jspServlet.addInitParameter("fork", "false");
              jspServlet.addInitParameter("xpoweredBy", "false");
              jspServlet.setLoadOnStartup(2);
              appContext.addChild(jspServlet);
              appContext.addServletMapping("*.jsp", "jsp");                

              tomcat.start();
              tomcat.getServer().await();
       }
}

App-servlet.xml（请注意，spring-beans-4.2.xsd和spring-context-4.2.xsd在POM中的版本与此完全相同-一些论坛认为这可能是一个错误）：

问题最有可能出现在打包过程中，多个spring依赖项具有不同的META-INF/spring.schema文件，这些文件相互覆盖。因此，最后一个jar有一个混乱的spring.schemas文件

要解决此问题，可以添加以下配置，以便.schema文件的内容采用正确的格式

我遵循了您的建议，现在出现了一个新错误“无法为JSP编译类”。在过去的8天里，我一直在努力获得一个嵌入Tomcat的可执行jar。当然，这个过程与包装过程有关，但我不知道我做错了什么。如果我在eclipse中运行应用程序，我可以使其正确运行，但我需要使用Tomcat访问一个可执行jar，或者放弃嵌入式方法，返回部署到服务器，我确信，如果我将EAR导出到Websphere或WAR导出到Tomcat服务器，并且忘记了embedded ideaI遵循了您的建议，那么我的所有想法都会起作用，现在我遇到了一个新错误“无法为JSP编译类”。在过去的8天里，我一直在努力获得一个嵌入Tomcat的可执行jar。当然，这个过程与包装过程有关，但我不知道我做错了什么。如果我在eclipse中运行应用程序，我可以使其正确运行，但我需要使用Tomcat访问一个可执行jar，或者放弃嵌入式方法，重新部署到服务器上。我确信，如果我将EAR导出到Websphere或WAR导出到Tomcat服务器，并且忘记了嵌入式思想，我的所有想法都会起作用
