jfinal集成cas单点认证实践
本示例jfinal集成cas单点认证，采用获取到登录用户session信息后，在本地站点备份一份session信息，主要做以下几个步骤：
1、站点引入响应jar包；
2、在web.xml中配置对应过滤器；
3、增加拦截handler，并在jfinal的config中配置。
此次示例在handler中获取登录用户session，并设置本站点session。
详细介绍如下：
1、引入jar包
需要引入两个jar包：cas-client-core-3.2.2.jar和commons-logging-1.2.jar；
将两个jar包放入站点WEB-INFO/lib下即可；
2、在web.xml中配置对应过滤器

注：cas的过滤器需要配置在jfinal过滤器前面，否则在handler中获取不到传入的登录用户session信息；
3、增加拦截handler，并在jfinal中配置
1 package com.handler; 2 3 import java.io.Console; 4 import java.util.Map; 5 import javax.servlet.http.HttpServletRequest; 6 import javax.servlet.http.HttpServletResponse; 7 import org.jasig.cas.client.authentication.AttributePrincipal; 8 import com.jfinal.handler.Handler; 9 import com.model.User; 10 11 /** 12 * 用于cas验证辅助使用,并存储用户信息到session 13 * @author sunflower 14 * 15 */ 16 public class CasHelpHandler extends Handler{ 17 18 @Override 19 public void handle(String target, HttpServletRequest request, 20 HttpServletResponse response, boolean[] isHandled) { 21 22 int index = target.lastIndexOf(";jsessionid"); 23 24 if(index>-1){ 25 target = index==-1?target:target.substring(0, index); 26 } 27 28 AttributePrincipal principal1 = (AttributePrincipal) request.getUserPrincipal(); 29 Map<String, Object> userMap = principal1.getAttributes(); 30 31 if(userMap!=null){ 32 User user=new User(); 33 user.setUserId(userMap.get("UserId").toString()); 34 user.setUserName(userMap.get("RealName").toString()); 35 user.setDeptId(userMap.get("DeptId").toString()); 36 user.setRoleId(userMap.get("RoleId").toString()); 37 request.getSession().setAttribute("user",user); 38 } 39 40 nextHandler.handle(target, request, response, isHandled); 41 } 42 43 }
1 package com.config; 2 3 import com.util.*; 4 import com.handler.CasHelpHandler; 5 import com.jfinal.config.Constants; 6 import com.jfinal.config.Handlers; 7 import com.jfinal.config.Interceptors; 8 import com.jfinal.config.JFinalConfig; 9 import com.jfinal.config.Plugins; 10 import com.jfinal.config.Routes; 11 import com.jfinal.ext.handler.UrlSkipHandler; 12 import com.jfinal.ext.route.AutoBindRoutes; 13 import com.jfinal.kit.PropKit; 14 import com.util.ConfigDBPluginHelper; 15 16 /** 17 * API引导式配?? 18 */ 19 public class Config extends JFinalConfig { 20 21 /** 22 * 配置常量 23 */ 24 public void configConstant(Constants me) { 25 // 加载少量必要配置，随后可用PropKit.get(...)获取?? 26 PropKit.use("config.txt"); 27 me.setDevMode(PropKit.getBoolean("devMode", false)); 28 } 29 30 /** 31 * 配置路由 32 */ 33 public void configRoute(Routes me) { 34 me.add(new AutoBindRoutes()); 35 36 // 根据xml文件配置,自动配置路由 37 ConfigRoutesHelper.configRouteInXml(getClass().getResource("/")+"deploy.xml", me); 38 } 39 40 /** 41 * 配置插件 42 */ 43 public void configPlugin(Plugins me) { 44 ConfigDBPluginHelper.configSqlServerPlugin(me); 45 } 46 47 /** 48 * 配置全局拦截?? 49 */ 50 public void configInterceptor(Interceptors me) { 51 52 } 53 54 /** 55 * 配置处理?? 56 */ 57 public void configHandler(Handlers me) { 58 // 增加例外 59 me.add(new CasHelpHandler()); 60 me.add(new UrlSkipHandler("/web/",true)); 61 me.add(new UrlSkipHandler("/$",true)); 62 } 63 }
如果找不到jfinal的配置文件，在web.xml中查看jfinal对应的configclass即可找到
1 <filter> 2 <filter-name>jfinal</filter-name> 3 <filter-class>com.jfinal.core.JFinalFilter</filter-class> 4 <init-param> 5 <param-name>configClass</param-name> 6 <param-value>com.config.Config</param-value> 7 </init-param> 8 </filter>
配置完成后，即对接成功~
