解决的方法，是在表单提交到ActionForm之前对requestq行~码?br>W一U方法，是写一个过滤器Q对所有请求进行过?br>
qo器代码：
package jp.co.ricoh.gtis.others.profile.filters;
import java.io.IOException;
import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
public class SetCharacterEncodingFilter implements Filter {
private String encoding;
public void init(FilterConfig filterConfig) throws ServletException {
// TODO Auto-generated method stub
this.encoding=filterConfig.getInitParameter("encoding");
}
public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain) throws IOException, ServletException {
// TODO Auto-generated method stub
request.setCharacterEncoding(this.encoding);
chain.doFilter(request,response);
}
public void destroy() {
// TODO Auto-generated method stub
}
}
配置文gweb.xml
<filter>
<filter-name>SetCharacterEncodingFilter</filter-name>
<filter-class>jp.co.ricoh.gtis.others.profile.filters.SetCharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-8</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>SetCharacterEncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
W二U方法是替换默认的控制器org.apache.struts.action.ActionServlet
子类代码Q?br>package jp.co.ricoh.gtis.others.profile.controllers;
import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.action.ActionServlet;
public class SetEncodingActionServlet extends ActionServlet {
protected void process(HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException {
// TODO Auto-generated method stub
String encoding = getInitParameter("encoding");
request.setCharacterEncoding(encoding);
super.process(request, response);
}
}
配置文gweb.xml
<servlet>
<servlet-name>testAction</servlet-name>
<servlet-class>jp.co.ricoh.gtis.others.profile.controllers.SetEncodingActionServlet</servlet-class>
<init-param>
<param-name>config</param-name>
<param-value>/WEB-INF/struts-config.xml</param-value>
</init-param>
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-8</param-value>
</init-param>
<load-on-startup>2</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>testAction</servlet-name>
<url-pattern>*.testdo</url-pattern>
</servlet-mapping>
此例Q凡是通过*.testdo来请求的数据Q都会经q参数encoding讑֮的值来~码?/p>
