Sip Servlets - 控制不傳遞給鏈中的下一個Servlet

2014-05-12 52 views

我正在使用Mobicents Sip Servlets 3.0.0-SNAPSHOT。我在DAR中配置了兩個servlet;一個用於檢查是否正在嘗試第三方註冊，另一個用於執行實際註冊。我發現當REGISTER到達時，它被傳遞給第一個servlet（BlockerApp）;但是當該servlet完成並代理下一個時，第二個servlet（RegApp）不會被調用。相反，再次調用第一個servlet，並將路由指令設置爲NEW。Sip Servlets - 控制不傳遞給鏈中的下一個Servlet

任何想法？我錯過了什麼嗎？

DAR配置：

REGISTER =（ 「RegApp」， 「DAR \：從」， 「始發」， 「」， 「NO_ROUTE」， 「1」），（ 「BlockerApp」，「DAR \：從」， 「始發」， 「」， 「NO_ROUTE」， 「0」）

第一個servlet：

import java.io.IOException; 

import javax.servlet.ServletException; 
import javax.servlet.sip.Proxy; 
import javax.servlet.sip.SipServlet; 
import javax.servlet.sip.SipServletRequest; 
import javax.servlet.sip.SipServletResponse; 
import javax.servlet.sip.SipURI; 

import org.apache.log4j.Logger; 

@javax.servlet.sip.annotation.SipServlet(name = "Blocker", loadOnStartup = 1) 
public class Blocker extends SipServlet { 
    private static final long serialVersionUID = 1L; 
    private static Logger logger = Logger.getLogger(Blocker.class); 
    private static final String LOOP_CHECK_HEADER = "X-looping"; 

    @Override 
    protected void doRegister(SipServletRequest req) throws ServletException, 
      IOException { 

     logger.info("######################################################"); 
     logger.info("Blocker"); 
     logger.info("region:" + req.getRegion()); 
     logger.info("routing directive:" + req.getRoutingDirective()); 
     logger.info("subscriber uri:" + req.getSubscriberURI()); 
     logger.info("popped route:" + req.getPoppedRoute()); 
     logger.info("######################################################"); 

     if (req.getHeader(LOOP_CHECK_HEADER) != null 
       && !req.getHeader(LOOP_CHECK_HEADER).isEmpty()) { 
      SipServletResponse resp = req 
        .createResponse(SipServletResponse.SC_FORBIDDEN); 
      resp.send(); 
      return; 
     } 
     req.addHeader(LOOP_CHECK_HEADER, "1"); 

     String toUser = null; 
     if (req.getTo().getURI().isSipURI()) { 
      toUser = ((SipURI) req.getTo().getURI()).getUser(); 
     } 

     String fromUser = null; 
     if (req.getFrom().getURI().isSipURI()) { 
      fromUser = ((SipURI) req.getFrom().getURI()).getUser(); 
     } 

     if (toUser != null && fromUser != null && toUser.equals(fromUser)) { 
      Proxy proxy = req.getProxy(); 
      proxy.proxyTo(req.getRequestURI()); 
     } else { 
      SipServletResponse rsp = req.createResponse(
        SipServletResponse.SC_DECLINE, 
        "No third party registrations accepted"); 
      rsp.send(); 
     } 

    } 

}

第二個servlet：

import java.io.IOException; 

import javax.annotation.Resource; 
import javax.ejb.EJB; 
import javax.servlet.ServletException; 
import javax.servlet.sip.Address; 
import javax.servlet.sip.SipFactory; 
import javax.servlet.sip.SipServlet; 
import javax.servlet.sip.SipServletRequest; 
import javax.servlet.sip.SipServletResponse; 
import javax.servlet.sip.SipURI; 

import org.apache.log4j.Logger; 

import com.mcleodnet.registrar.business.ContactInformationService; 
import com.mcleodnet.registrar.data.ContactUpdate; 

@javax.servlet.sip.annotation.SipServlet(name = "Registrar", loadOnStartup = 1) 
public class Registrar extends SipServlet { 
    private static final long serialVersionUID = 1L; 
    private static Logger logger = Logger.getLogger(Registrar.class); 

    @EJB(lookup = "java:global/Registrar/RegistrarDatabase/ContactInformationServiceImpl!com.mcleodnet.registrar.business.ContactInformationServiceLocal") 
    private ContactInformationService cis; 

    @Resource 
    SipFactory sipFactory; 

    @Override 
    protected void doRegister(SipServletRequest req) throws ServletException, 
      IOException { 

     logger.info("######################################################"); 
     logger.info("Registrar"); 
     logger.info("region:" + req.getRegion()); 
     logger.info("routing directive:" + req.getRoutingDirective()); 
     logger.info("subscriber uri:" + req.getSubscriberURI()); 
     logger.info("popped route:" + req.getPoppedRoute()); 
     logger.info("######################################################"); 

     SipServletResponse rsp = req.createResponse(SipServletResponse.SC_OK, 
       "OK"); 

     Address contactHeader = req.getAddressHeader("contact"); 
     String contactUri = contactHeader.getURI().toString(); 

     String username = null; 
     if (req.getTo().getURI().isSipURI()) { 
      username = ((SipURI) req.getTo().getURI()).getUser(); 
     } 

     int expires = req.getExpires(); 
     if (expires == -1) { 
      expires = contactHeader.getExpires(); 
     } 

     if (expires == 0) { 
      cis.deleteContactInformation(username); 
     } else { 
      cis.updateContactInformation(username, new ContactUpdate(
        contactUri, expires)); 
     } 

     rsp.send(); 
    } 

}

我現在明白爲什麼沒有爲我工作。使用DAR的SIP Servlet鏈接僅適用於使用INVITE，SUBSCRIBE，NOTIFY等對話框的方法。我嘗試使用DAR與處理INVITE的多servlet應用程序，並且它按預期工作。
