Spring 4.0.2.RELEASE和xfire1.2.6集成后出现一个奇葩问题

最近遇到一个奇葩的问题，我们的后台Dubbo服务已经和Spring 4.0.2.RELEASE版本集成，因为需要和一个第三方服务提供方对接，而对方提供的接口是web Service的，而且使用的框架是xfire。我们的技术对接童鞋，按照对方提供的技术文档进行代码编写，在pom.xml中添加了一段依赖导入相关需要的jar包,配置如下：

 <dependency>
    <groupId>org.codehaus.xfire</groupId>
    <artifactId>xfire-all</artifactId>
    <version>1.2.6</version>
</dependency>

然后当代码开发已经写得差不多了，在调试的时候就出现一个奇葩问题，老是报一个错org.xml.sax.SAXParseException; lineNumber: 5; columnNumber: 96; Document root element “beans”, must match DOCTYPE root “null”.

具体的报错信息如下：

经过查证相关资料，发现原来有一个xfire-all导入的一个jar包中依赖了一个1.2.6版本的spring的jar包，而我们的项目采用的Spring的版本就是4.0.2.RELEASE，所以就有冲突。
解决办法就是把spring相关的jar包exclusion。具体的办法是修改pom.xml:

<dependency>
        <groupId>org.codehaus.xfire</groupId>
        <artifactId>xfire-all</artifactId>
        <version>1.2.6</version>
        <exclusions>
            <exclusion>
                <artifactId>xfire-spring</artifactId>
                <groupId>org.codehaus.xfire</groupId>
            </exclusion>
        </exclusions>
    </dependency>
