url - Struts2中日文链接参数乱码

Answer 1

This is a simple filter that will do it. You just need to add this filter to your web.xml before the struts2 filter.

public class CharacterEncodingFilter implements Filter
{
    public void doFilter(ServletRequest request, ServletResponse response,
FilterChain next)
        throws IOException, ServletException
    {
        String encoding = request.getCharacterEncoding();
        if (encoding == null || encoding.length() == 0)
        {
            request.setCharacterEncoding("UTF-8");
        }

        next.doFilter(request, response);
    }

}

not sure though it will work as have not tried it myself :)

Update

even after the above Filter i was also facing the same issue and after some digging it as per my understanding is due to the fact that application server will by default use the ISO 8859-1 character encoding.

i added the following entry in my tomcat server.xml file

 <Connector port="8080" protocol="HTTP/1.1" 
               connectionTimeout="20000" 
               redirectPort="8443" URIEncoding="UTF-8"/>

URIEncoding="UTF-8"  // this is what i added 

and now i am able to see the proper character in my jsp page.same we have to do with java default encoding.

read this great article unicode-how-to-get-characters-right by BalusC.

hope this will help you.
