私のアプリケーションのチャットでは、5 つのサーブレットを使用しています。1 つのサーブレットにフィルターを適用する必要があります。
私のフィルターは、
package com.tps.flexchat.action;
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;
/**
* Servlet Filter implementation class EncodingFilter
*/
public class EncodingFilter implements Filter {
private String encoding = "UTF-8";
private FilterConfig filterConfig;
/**
* @see javax.servlet.Filter#init(javax.servlet.FilterConfig)
*/
public void init(FilterConfig filterConfig) throws ServletException {
this.filterConfig = filterConfig;
}
/**
* @see javax.servlet.Filter#doFilter(javax.servlet.ServletRequest, javax.servlet.ServletResponse, javax.servlet.FilterChain)
*/
public void doFilter(ServletRequest req, ServletResponse resp,FilterChain chain) throws IOException, ServletException {
resp.setCharacterEncoding("encoding");
resp.setContentType("encoding");
req.setCharacterEncoding(encoding);
chain.doFilter(req, resp);
System.out.println("filter -------> :"+encoding );
}
/**
* @see javax.servlet.Filter#destroy()
*/
public void destroy() {
}
}
web.xml のマッピングは次のようになります。
<filter>
<display-name>EncodingFilter</display-name>
<filter-name>EncodingFilter</filter-name>
<filter-class>com.tps.flexchat.action.EncodingFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>EncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
この SendMessageAction サーブレットのみに EncodingFilter フィルターを適用する必要があります。
package com.tps.flexchat.action;
import java.io.IOException;
import java.io.PrintWriter;
import java.net.URLDecoder;
import java.net.URLEncoder;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import com.genesyslab.platform.webmedia.protocol.FlexChatProtocol;
import com.tps.flexchat.Request.SendMessage;
import com.tps.flexchat.info.ApplicationInfo;
import com.tps.flexchat.info.CustomerInfo;
public class SendMessageAction extends HttpServlet {
private static final long serialVersionUID = 1L;
private String msg;
private String seckey;
private String uid;
private String sessionId;
private int counter;
private FlexChatProtocol protocol = null;
private SendMessage message;
public SendMessageAction() {
super();
}
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
msg = request.getParameter("message");
seckey = request.getParameter("securekey");
uid = request.getParameter("userId");
sessionId = request.getParameter("sessionId");
counter = 1;
protocol = ApplicationInfo.flexProtocol;
message = new SendMessage();
message.send(msg, seckey, uid, sessionId, counter, protocol);
CustomerInfo customer = ApplicationInfo.customerDetails.get(uid);
out.print(customer.getMessage());
}
}
前もって感謝します....
