配置参数如下：

<filter-name>SetCharacterEncoding</filter-name>
<filter-class>com.cwc.filter.SetCharacterEncodingFilter</filter-class>
- <init-param>
<param-name>encoding</param-name>
<param-value>UTF8</param-value>
</init-param>
- <init-param>
<param-name>operationNotPermit</param-name>
<param-value>not_permit.jsp</param-value>
</init-param>
</filter>
- <filter-mapping>
<filter-name>SetCharacterEncoding</filter-name>
<url-pattern>*.jsp</url-pattern>
</filter-mapping>
- <filter-mapping>
<filter-name>SetCharacterEncoding</filter-name>
<url-pattern>*.html</url-pattern>
</filter-mapping>
- <filter-mapping>
<filter-name>SetCharacterEncoding</filter-name>
<url-pattern>/appController/*</url-pattern>
</filter-mapping>
- <filter-mapping>
