解决XFire中文数据乱码

由于WEBSERVICE客户端的字符集与服务端有可能有差别，只需在WEB.XML中加入以下配置即可解决一些中文乱码问题：

? <filter>
???? <filter-name>encodingFilter</filter-name>
????? <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
????? <init-param>
????????? <param-name>encoding</param-name>
????????? <param-value>UTF-8</param-value>
????? </init-param>
????? <init-param>
????????? <param-name>forceEncoding</param-name>
????????? <param-value>true</param-value>
????? </init-param>
? </filter>

<filter-mapping>
??? <filter-name>encodingFilter</filter-name>
??? <url-pattern>/services/*</url-pattern>
?? </filter-mapping>
