maven+Spring+CXF的异常处理

本人学习Spring+CXF，参考了ice world的博文http://www.blogjava.net/icewee/archive/2012/07/06/382399.html#Post

用maven管理了这个简单demo，出现了以下异常：

严重: Servlet /spring-cxf-publish threw load() exception

查看国外网站，发现是由于servlet-api jar的冲突，需要去掉geronimo-servlet_x.x_spec-x.x.jar即可解决问题，贴出配置：

<properties>
    <cxf.version>2.2.3</cxf.version>
</properties>
<dependencies>
    <dependency>
    <groupId>org.apache.cxf</groupId>
    <artifactId>apache-cxf</artifactId>
    <version>${cxf.version}</version>
    <exclusions>
        <exclusion>
          <groupId>org.apache.geronimo.specs</groupId>
          <artifactId>geronimo-servlet_2.5_spec</artifactId>
        </exclusion>
    </exclusions>
    <type>pom</type>
     </dependency>
</dependencies>
