Question

我收到以下错误：

2014-06-30 15:14:08,089 ERROR [SinkRunner-PollingRunner-DefaultSinkProcessor] (org.apache.flume.SinkRunner$PollingRunner.run:160)  - Unable to deliver event. Exception follows.
org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Unable to locate Spring NamespaceHandler for XML schema namespace [http://www.springframework.org/schema/jee]
Offending resource: class path resource [beans/esb-message.xml]

esb-message.xml的标题是：

xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:integration="http://www.springframework.org/schema/integration"

xsi:schemaLocation="http://www.springframework.org/schema/beans

http://www.springframework.org/schema/util

据我所知，它基本上缺少了jee的NamespaceHandler。当我在线搜索时，JeeNamespaceHandler位于spring-context.jar中。我的maven-lib里有那个罐子。但为什么我仍然得到那个错误？

您使用的是什么版本的spring-context.jar？你有spring-schemas.jar的重复版本吗？展开jar，看看里面是否有META-INF/spring.schemas文件，内容如下：

http\://www.springframework.org/schema/jee/spring-jee-2.0.xsd=org/springframework/ejb/config/spring-jee-2.0.xsd
http\://www.springframework.org/schema/jee/spring-jee-2.5.xsd=org/springframework/ejb/config/spring-jee-2.5.xsd
http\://www.springframework.org/schema/jee/spring-jee-3.0.xsd=org/springframework/ejb/config/spring-jee-3.0.xsd
http\://www.springframework.org/schema/jee/spring-jee-3.1.xsd=org/springframework/ejb/config/spring-jee-3.1.xsd
http\://www.springframework.org/schema/jee/spring-jee-3.2.xsd=org/springframework/ejb/config/spring-jee-3.2.xsd
http\://www.springframework.org/schema/jee/spring-jee-4.0.xsd=org/springframework/ejb/config/spring-jee-4.0.xsd
http\://www.springframework.org/schema/jee/spring-jee.xsd=org/springframework/ejb/config/spring-jee-4.0.xsd

无法找到XML架构命名空间的Spring NamespaceHandler [http://www.springframework.org/schema/jee]
