描写江南古镇:从JSP界面向Action中传中文只显示??,如何解决？

1)首先编写filter类：
package myFilter;
import java.io.IOException;
import javax.servlet.*;
public class ChangeCharsetFilter implements Filter {
protected String encoding = null;/////要制定的编码，在web.xml中配置
protected FilterConfig filterConfig = null;
public void destroy() ｛
this.encoding = null;
this.filterConfig = null;
}
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
throws IOException, ServletException {
if (request.getCharacterEncoding() == null){
String encoding = getEncoding();////得到指定的编码名字
if (encoding != null)
request.setCharacterEncoding(encoding);////设置request的编码
}
chain.doFilter(request, response);///有机会执行下一个filter
}
public void init(FilterConfig filterConfig) throws ServletException {
this.filterConfig = filterConfig;
this.encoding = filterConfig.getInitParameter("encoding");///得到在web.xml中配置的编码
}
protected String getEncoding() {
return (this.encoding);///得到指定的编码
}

}
然后编辑web.xml文件，添加如下代码：
<filter>
<filter-name>SetCharacterEncoding</filter-name>
<filter-class>myFilter.ChangeCharsetFilter </filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>GB2312</param-value>//////指定编码为GB2312
</init-param>
</filter>
<filter-mapping>
<filter-name>SetCharacterEncoding</filter-name>
<url-pattern>/*</url-pattern>////////对于所有的request改变其编码
</filter-mapping>
