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包和%Java_HOME%\jdk\lib\tools.jar都拷贝到%TOMCAT_HOME%\webapps\WebReport\WEB-INF\lib下，如下图：
2.2 添加web.xml
在%TOMCAT_HOME%\webapps\webroot\WEB-INF目录下新建web.xml文件，内容如下：
<?xml version="1.0" encoding="UTF-8"?>
<web-app
xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
version="2.4">

<mime-type>application/x-msi</mime-type>
</mime-mapping>
<filter>

<param-name>edu.yale.its.tp.cas.client.filter.loginUrl</param-name>

<!--cas提供登陆页面的url-->

</init-param>

<param-name>edu.yale.its.tp.cas.client.filter.serverName</param-name>
<param-value>josie:8443</param-value>

</filter-mapping>
</web-app>
注：其中josie为个人配置的域名，请按照个人设置进行修改。
添加过滤信息，java代码如下：
package com.fr;
import com.fr.decision.webservice.utils.DecisionServiceConstants;
import com.fr.decision.webservice.v10.login.LoginService;
import com.fr.log.FineLoggerFactory;
import com.fr.stable.StringUtils;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class FrFilter implements Filter {
public FrFilter() {
}
@Override
public void init(FilterConfig filterConfig) throws ServletException {
}
@Override
public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {
HttpServletRequest req = (HttpServletRequest) servletRequest;
HttpServletResponse res = (HttpServletResponse) servletResponse;
HttpSession session = req.getSession(true);
String username;
Object object = req.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");
}
try {
if (StringUtils.isNotEmpty(username)) {
Object oldToken = session.getAttribute(DecisionServiceConstants.FINE_AUTH_TOKEN_NAME);
if (oldToken == null) {
String token = LoginService.getInstance().login(req, res, username);
session.setAttribute(DecisionServiceConstants.FINE_AUTH_TOKEN_NAME, token);
FineLoggerFactory.getLogger().info("fr FrFilter is over with username is ###" + username);
filterChain.doFilter(req, res);
} else {
filterChain.doFilter(req, res);
FineLoggerFactory.getLogger().info("no need");
}
} else {
throw new Exception("username is empty");
}
} catch (Exception e) {
FineLoggerFactory.getLogger().error(e.getMessage(), e);
}
}
@Override
public void destroy() {
}
}
将FrFilter.java编译成class文件，并放在%TOMCAT_HOME%\webroot\WEB-INF\classes\com\fr目录下。

2.3 测试
最后启动tomcat服务器，在浏览器中输入：https://localhost:8443/webroot/decision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：
