「無法找到XML模式命名空間的Spring NamespaceHandler」僅在可執行文件jar中發生

Question

我發現了幾個類似主題Context initialization failed org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 2 in XML document from ServletContext resource [/WEB-INF/App-servlet.xml] is invalid; nested exception is org.xml.sax.SAXParseException; systemId: http://www.springframework.org/schema/beans/spring-beans-4.2.xsd; lineNumber: 2; columnNumber: 18; s4s-elt-character: Non-whitespace characters are not allowed in schema elements other than 'xs:appinfo' and 'xs:documentation'.的問題。

我試圖應用我已閱讀的建議，但我不斷收到相同的錯誤。

此外，我還沒有發現一個特定的情況：下面的應用程序在Eclipse中完美工作。該錯誤只發生在可執行jar中。我的意思是，我點擊App.java並正確運行它。儘管如此，如果我導出爲Runnable Jar File並使用java -jar啓動它，我會看到下面顯示的錯誤。

靜態的主要方法：

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(); 
     } 
} 

的App-servlet.xml中（注意，彈簧豆-4.2.xsd和彈簧上下文4.2.xsd在POM具有確切版本 - 一些論壇建議成爲可能的錯誤）：

Answer 1

問題最有可能是在包裝過程中，多次對Spring的依賴有互相覆蓋不同的META-INF/spring.schemas文件。因此，最終的jar有一個亂七八糟的spring.schemas文件。

要解決此問題，您可以添加以下配置，以便.schema文件的內容格式正確。

<configuration> <transformers> <transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer"> <resource>META-INF/spring.handlers</resource> </transformer> <transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer"> <resource>META-INF/spring.schemas</resource> </transformer> </transformers> </configuration>
