修改记录 | 易学教程

一：实现普通用户的session共享

二.超管redis共享tocken

1.在第一步的RedisCacheManager类中多放入一个cache，取个别名就行，不用重新创建

 Cache cache = caches.get(name);
        if (cache == null) {
            cache = new RedisCache(redisTemplate);
            caches.put(name, cache);
            //超管登录时使用，实际就是原来的cache
            caches.put("superTicket", cache);
        }

2.直接替换SuperAdminTicketUtils类就可以，下面详情可忽略------------【序列化、修改引用、不可忽略】

2.把SuperAdminTicketUtils类的static方法都删掉，引用这个类中static方法放入类都改一下引用方式如下：【要把这个类交给spring去管理，加个注解就就好】

@Componentpublic class SuperAdminTicketUtils{

------------------------------------------------------------------------@Autowired
private SuperAdminTicketUtils superAdminTicketUtils;

2.1:在SuperAdminTicketUtils中注入RedisCacheManager

@Autowired
private RedisCacheManager redisCache ;

2.2：然后就可以得到cache实例进行相关的对象存取操作了【注意这里的user要实现序列化接口】

public String putTicket(AuthorizationUser user) {
        String ticket = getTicket();
        Cache<Object, ConcurrentHashMap<String, AuthorizationUser>> cache = redisCache.getCache("superTicket");
        ticketMap = cache.get("Super-Ticket:")==null?ticketMap:cache.get("Super-Ticket:");
        ticketMap.put(ticket, user);
        cache.put("Super-Ticket:",ticketMap);
        return ticket;
    }

序列化：实现接口后鼠标放在类上alt+Enter就可以生成uid

public class AuthorizationUser implements Serializable {

    private static final long serialVersionUID = -5556165398740497973L;

三：超管登录密码加密

1.引入js文件夹到plugin

2.layout-superlogin.html中引入JS

 <script class="custom-script" src="../../static/plugin/crypto-js/crypto-js.js" th:src="@{/plugin/crypto-js/crypto-js.js}"></script>
 <script class="custom-script" src="../../static/plugin/crypto-js/core.js" th:src="@{/plugin/crypto-js/core.js}"></script>
 <script class="custom-script" src="../../static/plugin/crypto-js/aes.js" th:src="@{/plugin/crypto-js/aes.js}"></script>

3.编写superlogin.js文件

var key = CryptoJS.enc.Utf8.parse("1234123412ABCDEF");  //十六位十六进制数作为密钥
var iv = CryptoJS.enc.Utf8.parse('ABCDEF1234123412');   //十六位十六进制数作为密钥偏移量
//解密方法
function Decrypt(word) {
    var encryptedHexStr = CryptoJS.enc.Hex.parse(word);
    var srcs = CryptoJS.enc.Base64.stringify(encryptedHexStr);
    var decrypt = CryptoJS.AES.decrypt(srcs, key, { iv: iv, mode: CryptoJS.mode.CBC, padding: CryptoJS.pad.Pkcs7 });
    var decryptedStr = decrypt.toString(CryptoJS.enc.Utf8);
    return decryptedStr.toString();
}

//加密方法
function Encrypt(word) {
    var srcs = CryptoJS.enc.Utf8.parse(word);
    var encrypted = CryptoJS.AES.encrypt(srcs, key, { iv: iv, mode: CryptoJS.mode.CBC, padding: CryptoJS.pad.Pkcs7 });
    return encrypted.ciphertext.toString().toUpperCase();
}
function superLogin(){
    var passWord = $("#signin-superamdin-password").val();
    if(passWord==null || passWord==""){
        passWord ="";
    }else{
        passWord = passWord.trim();
    }
    var prefix = getTimeStr("prefix");
    var suffix = getTimeStr("suffix");
    passWord = prefix+passWord+suffix
    var aesPassWord = Encrypt(passWord);
    $("#submit-superamdin-password").val(aesPassWord);
    return true;
}
function getTimeStr(flag){
    var myDate = new Date();

    var year = myDate.getFullYear(); //获取完整的年份(4位,1970-????)
    var month = myDate.getMonth()+1; //获取当前月份(0-11,0代表1月)
    month = month > 9 ? month : "0"+month;
    var day =  myDate.getDate(); //获取当前日(1-31)
    day = day > 9 ? day : "0"+day;
    var hours =  myDate.getHours(); //获取当前小时数(0-23)
    hours = hours > 9 ? hours : "0"+hours;
    var minutes =  myDate.getMinutes(); //获取当前分钟数(0-59)
    minutes = minutes > 9 ? minutes : "0"+minutes;
    var seconds =  myDate.getSeconds(); //获取当前秒数(0-59)
    seconds = seconds > 9 ? seconds : "0"+seconds;
    if(flag=="prefix"){
        return ""+year+month+day
    }else{
        return ""+hours+minutes+seconds
    }
}

3.1:替换html部分的form部分

4.可直接替换superloginController.java 详情如下

4.1：校验是否超时，获取时间差

public boolean checkLogionTime(String rangeTime){
        String strDate = rangeTime;
        //注意：SimpleDateFormat构造函数的样式与strDate的样式必须相符
        SimpleDateFormat simpleDateFormat=new SimpleDateFormat("yyyyMMddHHmmss");
        SimpleDateFormat df=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); //加上时间
        //必须捕获异常
        Date date= null;
        try {
            date = simpleDateFormat.parse(strDate);
        } catch (ParseException e) {
            e.printStackTrace();
        }
        long min = getDatePoor(new Date(),date);
        if(min>=loginTimeOut) {
            return false;
        }else{
            return true;
        }
    }
    //计算时间差  差多少分钟   绝对值
    public static long getDatePoor(Date endDate, Date loginDate) {
        long nd = 1000 * 24 * 60 * 60;
        long nh = 1000 * 60 * 60;
        long nm = 1000 * 60;
        // long ns = 1000;
        // 获得两个时间的毫秒时间差异
        long diff = endDate.getTime() - loginDate.getTime();
        // 计算差多少分钟
        long min = diff % nd % nh / nm;
        return Math.abs(min);
    }

4.2：验证之前解密直接加在原来的步骤中就好

public String login(ModelMap modal, String superAdminUsername, String superAdminPassword,
                        HttpServletRequest request, HttpServletResponse response) {
        if (StringUtils.isNotBlank(superAdminUsername) && StringUtils.isNotBlank(superAdminPassword)) {
            try {
                String str = AesUtil.desEncrypt(superAdminPassword);
                superAdminPassword = str.substring(8, str.length() - 6);
                String rangeTime =  str.substring(0,8)+str.substring(str.length()-6);
                boolean b = checkLogionTime(rangeTime);
                if(!b) {
                    modal.put(ErrorConstants.ERROR_MESSAGE, ErrorConstants.ERROR_SUPERADMIN_003);
                    return "views/superLoginPage";
                }
            } catch (Exception e) {
                LOGGER.error("decrypt applicationMetadataId failed", e);
            }
            SuperAdmin superAdmin = new SuperAdmin();
            superAdmin.setUsername(superAdminUsername.trim());

有个超时时间的设置在propertity中

# unit minutes
super.login.timeOut=5

5.后台要引入一个解密的Java工具类，ErrorConstants中加一个错误提示信息

public final static String ERROR_SUPERADMIN_003 = "登陆超时，不安全的请求！"; // 判断登录请求超过一定时间为不安全请求

完事！

四：单点登录ticket验证地址变更

1.ShiroCasConfig中假如如下配置

  @Value("${cas.server.url}")
  private String casServerUrl;

替换如下内容

  //@Bean(name = LOGOUT_FILTER_NAME)
    public ExtendLogoutFilter getExtendLogoutFilter(IAuthorizationService authorizationService) {
        ExtendLogoutFilter extLogoutFilter = new ExtendLogoutFilter();
        extLogoutFilter.setName(LOGOUT_FILTER_NAME);
        extLogoutFilter.setEnabled(true);
        extLogoutFilter.setAuthorizationService(authorizationService);
        extLogoutFilter.setRedirectUrl(casServerUrl + "/logout?service=" + shiroServerUrlPrefix);
        return extLogoutFilter;
    }

@Bean(name = SHIRO_FILTER_NAME)public ShiroFilterFactoryBean getShiroFilterFactoryBean(DefaultWebSecurityManager securityManager,                                                        IAuthorizationService authorizationService) {    ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();    shiroFilterFactoryBean.setSecurityManager(securityManager);    String loginUrl = casServerUrl + "/login?service=" + shiroServerUrlPrefix + WebConstants.CAS_FILTER_URI;    shiroFilterFactoryBean.setLoginUrl(loginUrl);

完事！
