1. 概述编辑
制作完上述步骤后，下面我们来看下如何将FR与CAS单点登录结合。
2. 实现过程编辑
2.1 拷贝jar
将cas两个client-jar包拷贝到%TOMCAT_HOME%\webapps\WebReport\WEB-INF\lib下，如下图：
2.2 修改web.xml
首先打开%TOMCAT_HOME%\webapps\WebReport\WEB-INF下的web.xml文件，找到以下代码
<servlet>
<servlet-name>ReportServer</servlet-name>
<servlet-class>com.fr.web.ReportServlet</servlet-class>
<load-on-startup>0</load-on-startup>
在上面加入如下过滤条件：
<filter>
<filter-name>CASFilter</filter-name>
<filter-class>edu.yale.its.tp.cas.client.filter.CASFilter</filter-class>
<init-param>
<param-name>edu.yale.its.tp.cas.client.filter.loginUrl</param-name>
<param-value>https://suise:8443/cas/login</param-value>
<!--cas提供登陆页面的url-->
</init-param>
<init-param>
<param-name>edu.yale.its.tp.cas.client.filter.validateUrl</param-name>
<param-value>https://suise:8443/cas/proxyValidate</param-value>
<!--cas提供service ticker或者proxy ticket验证服务的url-->
</init-param>
<init-param>
<param-name>edu.yale.its.tp.cas.client.filter.serverName</param-name>
<param-value>suise:8443</param-value>
<!--客户端应用的域名和端口-->
</init-param>
</filter>
<filter-mapping>
<filter-name>CASFilter</filter-name>
<url-pattern>/ReportServer</url-pattern>
</filter-mapping>
若报表应用设置了权限，则需要将如下java代码：
package com.fr;
import com.fr.base.FRContext;
import com.fr.fs.base.entity.User;
import com.fr.fs.base.entity.UserInfo;
import com.fr.fs.control.UserControl;
import com.fr.fs.privilege.auth.FSAuthentication;
import com.fr.fs.privilege.base.FServicePrivilegeLoader;
import com.fr.fs.privilege.entity.DaoFSAuthentication;
import com.fr.privilege.session.PrivilegeInfoSessionMananger;
import org.jasig.cas.client.validation.Assertion;
import javax.servlet.*;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;
import java.io.IOException;
public class FrFilter implements Filter {
public FrFilter() {
}
public void doFilter(ServletRequest req, ServletResponse res, FilterChain filterChain) throws IOException, ServletException {
HttpServletRequest re = (HttpServletRequest) req;
HttpServletResponse resp = (HttpServletResponse) res;
HttpSession session = re.getSession(true);
String username;
String userpass = "";
Object object = re.getSession().getAttribute("_const_cas_assertion_");
if (object != null) {
Assertion assertion = (Assertion) object;
username = assertion.getPrincipal().getName();
} else {
username = (String) session.getAttribute("edu.yale.its.tp.cas.client.filter.user");
if (username == null || "".equals(username)) {
resp.sendRedirect("http://www.baidu.com"); //如果用户名为空跳转到百度
}
}
try {
User user1 = UserControl.getInstance().getByUserName(username);
if (user1 != null && session.getAttribute("fr_fs_auth_key") == null) { //如果用户名在fs的用户列表里则做登陆操作
FSAuthentication authentication = new DaoFSAuthentication(new UserInfo(user1.getId(), user1.getUsername(), user1.getPassword()));
long userid = authentication.getUserInfo().getId();
PrivilegeInfoSessionMananger.login(new FServicePrivilegeLoader(username, UserControl.getInstance().getAllSRoleNames(userid), UserControl.getInstance().getUserDP(userid)), session, resp);
session.setAttribute("fr_fs_auth_key", authentication);
UserControl.getInstance().login(userid);
System.out.println("fr FrFilter is over with username is -" + username + "- and userpass is -" + userpass + "-");
FRContext.getLogger().error("fr FrFilter is over with username is ###" + username + "### and userpass is ###" + userpass + "###");
filterChain.doFilter(req, res);
} else if (user1 != null & session.getAttribute("fr_fs_auth_key") != null) {
filterChain.doFilter(req, res);
FRContext.getLogger().error("no need");
} else {
resp.sendRedirect("http://www.hao123.com"); //如果用户名不在fs的用户列表里则跳转hao123
}
} catch (Exception var14) {
var14.printStackTrace();
}
}
public void init(FilterConfig filterconfig) throws ServletException {
}
public void destroy() {
}
}
将FrFilter.java编译成class文件，并放在%TOMCAT_HOME%\WebReport\WEB-INF\classes\com\fr目录下。
然后在web.xml文件中增加如下代码：
<filter>
<filter-name>FrFilter</filter-name>
<filter-class>com.fr.FrFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>FrFilter</filter-name>
<url-pattern>/ReportServer</url-pattern>
</filter-mapping>
2.3 测试
最后启动tomcat服务器，在浏览器中输入：https://localhost:8443/WebReport/ReportServer?op=fs即进入了cas登录界面，通过cas认证后，FRFilter会看用户名是否在fs的用户中，如果在，则登录成功，否则登录失败跳转hao123，如下图：
