Question

我在Tomcat中启动Spring Web应用程序时收到以下错误。

基本上，在处理beans.xml文件时，将按顺序加载以下类。

org.springframework.context.config.ContextNamespaceHandler处理URI http://www.springframework.org/schema/context

org.springframework.beans.factory.xml.UtilNamespaceHandler处理URI http://www.springframework.org/schema/util

org.apache.cxf.jaxws.spring.NamespaceHandler处理URI http://cxf.apache.org/jaxws

org.apache.cxf.transport.http.spring.NamespaceHandler处理URI http://cxf.apache.org/transports/http/configuration

org.springframework.batch.core.configuration.xml.CoreNamespaceHandler处理URI http://www.springframework.org/schema/batch

但是当它为批处理URI加载上面的最后一个类时，会发生以下异常。

12/28/2017-11:21:47.070 - localhost-startStop-1 - ERROR [org.springframework.web.context.ContextLoader : Line 227]: Context initialization failed 
org.springframework.beans.factory.BeanDefinitionStoreException: Unexpected exception parsing XML document from class path resource [beans.xml]; nested exception is org.springframework.beans.FatalBeanException: Class [org.springframework.batch.core.configuration.xml.CoreNamespaceHandler] for namespace [http://www.springframework.org/schema/batch] does not implement the [org.springframework.beans.factory.xml.NamespaceHandler] interface
    at org.springframework.beans.factory.xml.XmlBeanDefinitionReader.doLoadBeanDefinitions(XmlBeanDefinitionReader.java:412)
    at org.springframework.beans.factory.xml.XmlBeanDefinitionReader.loadBeanDefinitions(XmlBeanDefinitionReader.java:334)

我查看了上述所有类的来源，发现所有类都扩展了

org.springframework.beans.factory.xml.NamespaceHandlerSupport

反过来实现

org.springframework.beans.factory.xml.NamespaceHandler

我已经检查了类路径上的jar，它们看起来很好，在各自的预期spring jar文件中包含上面的类和接口。

知道如何解决这个问题吗？

类似的问题在这里，我已经尝试了什么。

Unexpected exception parsing XML document from class path resource [config/FaceBookSimulator.xml];

和

Unable to locate Spring NamespaceHandler for XML schema namespace [http://www.springframework.org/schema/batch]

更新

我使用-verbose：class选项重新启动Tomcat，以打印从任何jar文件加载的所有类。我发现了以下内容：

班级

org.springframework.beans.factory.xml.DefaultNamespaceHandlerResolver

正在处理：

http://www.springframework.org/schema/batch=org.springframework.batch.core.configuration.xml.CoreNamespaceHandler

DefaultNamespaceHandlerResolver不扩展NamespaceHandlerSupport（实现NamespaceHandler）。

如果发现是对的，如何解决这个问题？

Answer 1

我的应用程序依赖于服务器lib目录下的共享jar文件。有很多罐子。我需要整理服务端的jar文件。但最快的解决方案是将所需的jar包装在WAR文件的WEB-INF / lib中。

命名空间类[http://www.springframework.org/schema/batch]未实现[org.springframework.beans.factory.xml.NamespaceHandler]接口
