How to allow some actions using other special encodings(Struts2)

our default encoding of actions all is UTF-8.

[web.xml]

---

<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>

<filter-name>struts</filter-name>

<filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>

</filter>

<filter-mapping>

<filter-name>encodingFilter</filter-name>

<url-pattern>/*</url-pattern>

</filter-mapping>

<filter-mapping>

<filter-name>securityFilter</filter-name>

<url-pattern>/*</url-pattern>

</filter-mapping>

</filter-name>

</filter>

-----

In order to allow some actions using other encoding(ex:Shift-JIS) different with default encoding(UTF-8), we should use EncodingFilter class as a new filter and
define it before FilterDispatcher.

Added portion

<filter>

<filter-name>encoding</filter-name>

<filter-class> util.EncodingFilter</filter-class>

<init-param>

<param-name>encoding</param-name>

<!--new encoding which System needs to suppport-->

<param-value>Shift_JIS</param-value>

</init-param>

</filter>

<filter-mapping>

<filter-name>encoding</filter-name>

<!--specialcoding.action is the action which System needs to support with Shift_JIS-->

<url-pattern>/specialencoding.action</url-pattern>

</filter-mapping>
