单点登录需要在需要进入的子系统B中添加一个类，用于接收A系统传过来的参数；

@Action(value = "outerLogin", results = {            @Result(name = "redirect", type = "redirect", location = "${innerUrl}")    })    public String outerLogin() {        try {            if (userName != null && userName.trim().length() > 0) {                TPolicemen policemen = policeMenService.getPolicemenByJh(userName);                if (policemen != null) {                    //获取当前登录用户所在IP                    String ipStr = CommonService.getIpAddr(this.request);                    policemen.setIpStr(ipStr);                    this.session.put(AuthInterceptor.USER_SESSION_KEY, policemen);                    response.setHeader("P3P", "CP=CAO PSA OUR");                    innerUrl = outerUrl;                    return "redirect";                } else {                    loginStr = "用户名或者密码错误";                }            }        } catch (Exception e) {            this.clientMessage(e.getMessage());        }        return "login";    }

A系统中点击某个链接，url格式形如：

防止iframe跨域访问cookie/session丢失的解决办法是，在保存session后添加一段代码：即

response.setHeader("P3P", "CP=CAO PSA OUR");
