单点登录 - 梦想修炼场

系统中两种单点登录实现方式：

1、直接登录单点登录认证系统。

2、登录业务系统，如用户此时为首次登录，则跳转得到单点登录认证界面。如用户已通过认证，则直接登录到业务系统。

【补充说明】

单点登录认证服务器地址：http://192.168.61.124:8080/SSOAuth_v1.0.0/

业务系统服务器地址：http://192.168.61.134:8080/sepmis_v1.3.0/

直接登录单点登录认证系统流程：

1、打开单点登录认证服务器登录页面，输入用户名密码。

2、如果通过认证，此时页面跳转到系统主界面main.jsp。这个时候在加载main.jsp页面同时，页面后端通过ajax中jsonp方式，向单点登录认证服务器后台Action发送hello请求。需要传递参数，当前用户代码。

main.jsp页面核心代码如下：

<%
    UserSession userSession = (UserSession)session.getAttribute(AppConst.USER_SESSION_ID);
    String userCode = "";
    String userName = "";
    
    if(null != userSession){
       userCode = userSession.getUserCode();
       userName = userSession.getUserType();
    }
%>  
 
<script type="text/javascript">
    $.ajax({  
       type: "get",  
       contentType: "application/json",
       url: "http://192.168.61.124:8080/SSOAuth_v1.0.0/hello.do?usercode=<%=userCode%>&callback=?",  
       crossDomain: true,
       success: function(data) {  
            $.each(data.msg, function () {
                $.getJSON(this); 
            });
       }
    });  
    </script>

UserSession userSession = (UserSession)session.getAttribute(AppConst.USER_SESSION_ID);

String userCode = "";

String userName = "";

if(null != userSession){

userCode = userSession.getUserCode();

userName = userSession.getUserType();

}

$.ajax({

type: "get",

contentType: "application/json",

url: "http://192.168.61.124:8080/SSOAuth_v1.0.0/hello.do?usercode=<%=userCode%>&callback=?",

crossDomain: true,

success: function(data) {

$.each(data.msg, function () {

$.getJSON(this);

});

}

});

</script>

3、后台接受hello请求，通过传递的参数用户代码，在SysRealuser表中判断用户所能够访问到的业务系统对象。拿到业务系统对象中url参数，组织各个业务系统setCookie Url。然后通过json异步传回前台。

Url格式例如：(红色字体处为变量)

http://192.168.61.134:8080/sepmis_v1.3.0/setCookie.do?userCode=xxx&&callback=?

代码如下：

/**
     * 当用户成功通过单点登录系统认证后，用户进入系统操作界面，同时页面异步发送此action请求
     * 获取创建json对象，对象内容为页面使用ajax异步访问各个业务系统的 setcookie action方法
     * @return result
     */
    public String hello(){
       try {
           List&lt;SysInfo&gt; tmp = getUserSysRealSys();
           UserSession userSession = AuthorityUtil.getSysUserSession();
           JSONObject jsonObject = new JSONObject();
           JSONArray jsonArray = new JSONArray();
           if(tmp!=null &amp;&amp; tmp.size()&gt;0){
              for(int i=0; i&lt;tmp.size(); i++){
                  jsonArray.put(tmp.get(i).getSysUrl() + "/setCookie.do?userCode="+userSession.getUserCode()+"&amp;callback=?");
              }
           }
            jsonObject.put("msg", jsonArray);
            response.setContentType("application/json");
            response.setCharacterEncoding("UTF-8");  
            response.setHeader("Cache-Control", "no-cache");  
           response.getWriter().write(jsonObject.toString());
           response.getWriter().flush();
           //释放资源
           tmp = null;
           userSession = null;
           //打印日志
           String info  = LoggerUtil.getInfoMsg("AJAX异步访问，用户权限范围内各业务系统的 setCookie方法");
           log.info(info);
           return null;
       } catch (IOException ie) {
           this.exceptionMessage.setError(ie.toString());
           this.exceptionMessage.setClassName(this.getClass().getName());
           this.exceptionMessage.setMessage("AJAX异步访问出现IO异常！");
           log.error(ie.toString());
           return ERROR;
       } catch (Exception ex) {
           this.exceptionMessage.setError(ex.toString());
           this.exceptionMessage.setClassName(this.getClass().getName());
           this.exceptionMessage.setMessage("AJAX异步访问出现异常！");
           log.error(ex.toString());
           return ERROR;
       }
    }

/**

* 当用户成功通过单点登录系统认证后，用户进入系统操作界面，同时页面异步发送此action请求

* 获取创建json对象，对象内容为页面使用ajax异步访问各个业务系统的 setcookie action方法

* @return result

public String hello(){

try {

List<SysInfo> tmp = getUserSysRealSys();

UserSession userSession = AuthorityUtil.getSysUserSession();

JSONObject jsonObject = new JSONObject();

JSONArray jsonArray = new JSONArray();

if(tmp!=null && tmp.size()>0){

for(int i=0; i<tmp.size(); i++){

jsonArray.put(tmp.get(i).getSysUrl() + "/setCookie.do?userCode="+userSession.getUserCode()+"&callback=?");

}

jsonObject.put("msg", jsonArray);

response.setContentType("application/json");

response.setCharacterEncoding("UTF-8");

response.setHeader("Cache-Control", "no-cache");

response.getWriter().write(jsonObject.toString());

response.getWriter().flush();

//释放资源

tmp = null;

userSession = null;

//打印日志

String info = LoggerUtil.getInfoMsg("AJAX异步访问，用户权限范围内各业务系统的 setCookie方法");

log.info(info);

return null;

} catch (IOException ie) {

this.exceptionMessage.setError(ie.toString());

this.exceptionMessage.setClassName(this.getClass().getName());

this.exceptionMessage.setMessage("AJAX异步访问出现IO异常！");

log.error(ie.toString());

return ERROR;

} catch (Exception ex) {

this.exceptionMessage.setError(ex.toString());

this.exceptionMessage.setClassName(this.getClass().getName());

this.exceptionMessage.setMessage("AJAX异步访问出现异常！");

log.error(ex.toString());

return ERROR;

}

4、前台main.jsp页面这时拿到传回的URL参数，此时执行Success代码段中的函数

success: function(data) {  
            $.each(data.msg, function () {
                $.getJSON(this); 
            });

success: function(data) {

$.each(data.msg, function () {

$.getJSON(this);

});

此时function中参数data就是传回的URL参数，然后遍历执行Jquery中getJSON方法。此时通过AJAX技术异步又向各个业务系统发送setCookie请求，此操作可以视为一种透明的登录操作，用户是不能够感知到。

5、业务系统接受setCookie action请求。

代码如下：

public String setCookie(){
       try{
           // - 查找用户岗位集合
           StringBuilder hql = new StringBuilder(300);
           userCode = request.getParameter("userCode");
           hql.append("FROM SysUser WHERE userCode ='").append(userCode).append("'");
           List&lt;SysUser&gt; sysUserList = sysUserService.findByHql(hql.toString());
           if(sysUserList.size() &gt; 0){
              Cookie cookie = new Cookie("sso", userCode);
              cookie.setPath("/");
              //设置cookie的有效期，单位是秒;
              //如果不使用这个方法或者参数为负数的话，当浏览器关闭的时候，这个cookie就失效了
              //cookie一年内有效60*60*24*365
              cookie.setMaxAge(60*60); 
              response.addCookie(cookie);
           }
       }catch(Exception ex){
           //返回异常信息
           this.exceptionMessage.setError(ex.toString());
           this.exceptionMessage.setClassName(this.getClass().getName());
           this.exceptionMessage.setMessage("用户登录出现异常！");
           log.info(ex.toString());
           return ERROR;
       }
       return null;
    }

public String setCookie(){

try{

// - 查找用户岗位集合

StringBuilder hql = new StringBuilder(300);

userCode = request.getParameter("userCode");

hql.append("FROM SysUser WHERE userCode ='").append(userCode).append("'");

List<SysUser> sysUserList = sysUserService.findByHql(hql.toString());

if(sysUserList.size() > 0){

Cookie cookie = new Cookie("sso", userCode);

cookie.setPath("/");

//设置cookie的有效期，单位是秒;

//如果不使用这个方法或者参数为负数的话，当浏览器关闭的时候，这个cookie就失效了

//cookie一年内有效60*60*24*365

cookie.setMaxAge(60*60);

response.addCookie(cookie);

}

}catch(Exception ex){

//返回异常信息

this.exceptionMessage.setError(ex.toString());

this.exceptionMessage.setClassName(this.getClass().getName());

this.exceptionMessage.setMessage("用户登录出现异常！");

log.info(ex.toString());

return ERROR;

}

return null;

}

业务系统通过setCookie方法，将此用户在业务系统中Cookie存储到用户本地。

6、输入业务系统连接。

业务系统同后台通过filter过滤所有请求，获取用户在当前服务器域下Cookie值，进行校验，通过校验进入系统，未通过校验返回单点登录认证页面。

SSOFilter.java核心代码如下

/**
     * servlet filter 过滤方法
     * @param ServletRequest
     * @param ServletResponse
     * @param FilterChain
     * @throws IOException,ServletException
     */
    public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException {
       // 用户本地cookie值
       String cookieValue = "";
       HttpServletRequest request = (HttpServletRequest) req;
       HttpServletResponse response = (HttpServletResponse) res;
       String url = request.getRequestURL().toString();
       // 返回结果
       String result = null;
       
       // 根据上下文根截取URL
       String[] urlArray = url.split(request.getContextPath());
       //如果是业务service地址，跳转到业务系统单点登录action
       if (urlArray.length == 2 &amp;&amp; ("/").equals(urlArray[1])) {
           response.sendRedirect(url+"loginSSO.do");
           return;
       }else {
           for(int i=0; i&lt;urlArray.length; i++){
              if("/setCookie.do".equals(urlArray[i])){
                  result = "setCookie";
                  break;
              }
           }
       }
       
       // 检查HTTP请求的head是否有需要的cookie
       Cookie[] diskCookies = request.getCookies();
       if (diskCookies != null) {
           log.info("【权限系统-用户认证过滤器】找到COOKIES");
           for (int i = 0; i &lt; diskCookies.length; i++) {
              cookieValue = diskCookies[i].getValue();
              log.info("【权限系统-用户认证过滤器】COOKIES中找到用户标识:" + diskCookies[i].getName() + "=" + cookieValue);
              if (SSO_AUTH.equals(diskCookies[i].getName())) {
                  result = SSOService(cookieValue);
                  if ("success".equals(result)) {
                     log.info("【通过单点登录服务器认证】");
                  } else {
                     log.info("【未通过单点登录服务器认证】COOKIES认证失败");
                     response.sendRedirect(ssoLoginPage);
                  }
              } else if ("sso".equals(diskCookies[i].getName())) {
                  HttpSession session =  request.getSession(); 
                  session.setAttribute("sso", cookieValue);
                  result = "success";
              }
           }
       } else {
           log.info("【权限系统-用户认证过滤器】未找到COOKIES");
       }
       
       // COOKIES效验,转到单点登录认证页面
       if (result.equals("failed")) {
           log.info("【权限系统-用户认证过滤器】COOKIES认证失败");
           response.sendRedirect(ssoLoginPage);
       // 效验成功并退出服务
       } else if (result.equals("logout")) {
           log.info("【权限系统-用户认证过滤器】退出登录");
           //logoutService(cookieValue);
           response.sendRedirect(ssoLoginPage);
       // 效验成功
       } else {
           log.info("【权限系统-用户认证过滤器】认证成功");
           Throwable problem = null;
           try {
              chain.doFilter(req, res);
           } catch (Throwable t) {
              problem = t;
              t.printStackTrace();
           }
           if (problem != null) {

执行通过业务系统fileter将，根据不同的请求进行不同的操作。获取业务系统Cookie后同构使用HttpClient类方法调用单点认证中的authcookie方法，验证用户Cookie的合法性。

未通过认证，登录业务系统，跳转到单点登录认证。

1、输入业务系统服务地址

2、系统自动跳转到单点登录服务器，下边过程同上“直接登录单点登录认证系统流程”

其原理是通过filter实现类中dofilter方法进行过滤，判断用没有Cookie，则进行跳转到单点登录认证界面。

过滤代码如下：

// 检查HTTP请求的head是否有需要的cookie
       Cookie[] diskCookies = request.getCookies();
       if (diskCookies != null) {
           log.info("【权限系统-用户认证过滤器】找到COOKIES");
           for (int i = 0; i &lt; diskCookies.length; i++) {
              cookieValue = diskCookies[i].getValue();
              log.info("【权限系统-用户认证过滤器】COOKIES中找到用户标识:" + diskCookies[i].getName() + "=" + cookieValue);
              if (SSO_AUTH.equals(diskCookies[i].getName())) {
                  result = SSOService(cookieValue);
                  if ("success".equals(result)) {
                     log.info("【通过单点登录服务器认证】");
                  } else {
                     log.info("【未通过单点登录服务器认证】COOKIES认证失败");
                     response.sendRedirect(ssoLoginPage);
                  }
              } else if ("sso".equals(diskCookies[i].getName())) {
                  HttpSession session =  request.getSession(); 
                  session.setAttribute("sso", cookieValue);
                  result = "success";
              }
           }
       } else {
           log.info("【权限系统-用户认证过滤器】未找到COOKIES");
       }
       
       // COOKIES效验,转到单点登录认证页面
       if (result.equals("failed")) {
           log.info("【权限系统-用户认证过滤器】COOKIES认证失败");
           response.sendRedirect(ssoLoginPage);
       // 效验成功并退出服务
       } else if (result.equals("logout")) {
           log.info("【权限系统-用户认证过滤器】退出登录");
           //logoutService(cookieValue);
           response.sendRedirect(ssoLoginPage);
       // 效验成功
       } else {
           log.info("【权限系统-用户认证过滤器】认证成功");
           Throwable problem = null;
           try {
              chain.doFilter(req, res);
           } catch (Throwable t) {
              problem = t;
              t.printStackTrace();
           }
           if (problem != null) {
              if (problem instanceof ServletException) {
                  throw ((ServletException) problem);
              }
              if (problem instanceof IOException) {
                  throw ((IOException) problem);
              }
              sendProcessingError(problem, res);
           }
       }

// 检查HTTP请求的head是否有需要的cookie

Cookie[] diskCookies = request.getCookies();

if (diskCookies != null) {

log.info("【权限系统-用户认证过滤器】找到COOKIES");

for (int i = 0; i < diskCookies.length; i++) {

cookieValue = diskCookies[i].getValue();

log.info("【权限系统-用户认证过滤器】COOKIES中找到用户标识:" + diskCookies[i].getName() + "=" + cookieValue);

if (SSO_AUTH.equals(diskCookies[i].getName())) {

result = SSOService(cookieValue);

if ("success".equals(result)) {

log.info("【通过单点登录服务器认证】");

} else {

log.info("【未通过单点登录服务器认证】COOKIES认证失败");

response.sendRedirect(ssoLoginPage);

}

HttpSession session = request.getSession();

session.setAttribute("sso", cookieValue);

result = "success";

}

} else {

}

// COOKIES效验,转到单点登录认证页面

if (result.equals("failed")) {

log.info("【权限系统-用户认证过滤器】COOKIES认证失败");

response.sendRedirect(ssoLoginPage);

// 效验成功并退出服务

} else if (result.equals("logout")) {

log.info("【权限系统-用户认证过滤器】退出登录");

//logoutService(cookieValue);

response.sendRedirect(ssoLoginPage);

// 效验成功

} else {

log.info("【权限系统-用户认证过滤器】认证成功");

Throwable problem = null;

try {

chain.doFilter(req, res);

} catch (Throwable t) {

problem = t;

t.printStackTrace();

}

if (problem != null) {

if (problem instanceof ServletException) {

throw ((ServletException) problem);

sendProcessingError(problem, res);
