   jforum是一个不错的开源BBS论坛,支持中文,操作方便,容易扩展,是一个不错的选择。通过参考网上的资料,下面给出了jforum与web项目整合的方法:
1、实现SSO类:

package net.jforum.sso;

import javax.servlet.http.Cookie;

import net.jforum.ControllerUtils;
import net.jforum.context.RequestContext;
import net.jforum.entities.UserSession;
import net.jforum.util.preferences.ConfigKeys;
import net.jforum.util.preferences.SystemGlobals;
import org.apache.log4j.Logger;
 
  public class CookieUserSSO implements SSO {     
    
    static final Logger logger = Logger.getLogger(CookieUserSSO.class.getName());     
    
    public String authenticateUser(RequestContext request) { 
         // myapp login cookie, contain logged username     
        Cookie myCookie = ControllerUtils.getCookie("jforumSSOCookieNameUser");     
             
        String username = null;          
        if (myCookie != null) username = myCookie.getValue();      
        System.out.println("cookie_name1="+myCookie.getName());   
        System.out.println("cookie value1="+myCookie.getValue());  
             
        if (myCookie == null || username.trim().equals("")) {     
            //JForumExecutionContext.setRedirect(SystemGlobals.getValue(ConfigKeys.SSO_REDIRECT));     
            return null; // no cookie found     
        }      
        System.out.println("cookie_name2="+myCookie.getName());  
        System.out.println("cookie value2="+myCookie.getValue());  
        return username; // jforum username     
    }     
    
    public boolean isSessionValid(UserSession userSession, RequestContext request) {   
  System.out.println("执行isSessionValid方法");
        Cookie SSOCookie = ControllerUtils.getCookie("jforumSSOCookieNameUser"); // myapp login cookie      
                       
        String remoteUser = null;     
             
        if (SSOCookie != null) remoteUser = SSOCookie.getValue(); //  jforum username     
    
        // user has since logged out     
        if(remoteUser == null &&      
                userSession.getUserId() != SystemGlobals.getIntValue(ConfigKeys.ANONYMOUS_USER_ID)) {     
            return false;     
        // user has since logged in     
        } else if(remoteUser != null &&      
                userSession.getUserId() == SystemGlobals.getIntValue(ConfigKeys.ANONYMOUS_USER_ID)) {     
            return false;     
        // user has changed user     
        } else if(remoteUser != null && !remoteUser.equals(userSession.getUsername())) {     
            return false;     
        }     
        return true; // myapp user and forum user the same     
    }     
}    

把该类放在jforum\WEB-INF\classes下,然后用javac  -d  .  CookieUserSSO .java 命令编译,.class文件存放在jforum\WEB-INF\classes\net\jforum\sso下。
2、修改SystemGlobals.properties
   有些JForum版本为jforum-custom.conf文件。
   查找“SSO”字样,找到“SSO / User authentication”配置部分,将其修改为以下内容:
authentication.type = sso-----------特别注意:sso用小写,不能用大写
##...
sso.implementation = net.jforum.sso.CookieUserSSO----------你自己实现的SSO类
##...
sso.redirect=http://localhost:port/jforum---------------例如:sso.redirect=http://localhost:8082/jforum
3、在程序的登录或注销部分加入如下代码:
     登录:
Cookie cookie = new Cookie("jforumSSOCookieNameUser",name);-------name为从登录界面取得的用户名,把它加入到cookie里面
  cookie.setPath("/");
  cookie.setMaxAge(-1);//设置cookie的生命周期为:会话级,即浏览器关闭,该cookie就消失了
  response.addCookie(cookie);

    注销:

  Cookie cookie =  new    Cookie(jforumSSOCookieNameUser, "");
  cookie.setMaxAge(0); // delete the cookie.
  response.addCookie(cookie);

4、在html/jsp页面加入超链接:
<a href="/jforum">转到论坛</a>

这就配置完成了。
