在线用户

前端调用后台接口

/** 查询登录日志列表 */
getList() {
    this.loading = true;
    list(this.queryParams).then(response => {
        this.list = response.rows;
        this.total = response.total;
        this.loading = false;
    });
}

原理：
通过token的key前缀获取所有token

@PreAuthorize("@ss.hasPermi('monitor:online:list')")
@GetMapping("/list")
public TableDataInfo list(String ipaddr, String userName)
{
    Collection<String> keys = redisCache.keys(Constants.LOGIN_TOKEN_KEY + "*");
    List<SysUserOnline> userOnlineList = new ArrayList<SysUserOnline>();
    for (String key : keys)
    {
        LoginUser user = redisCache.getCacheObject(key);
        if (StringUtils.isNotEmpty(ipaddr) && StringUtils.isNotEmpty(userName))
        {
            if (StringUtils.equals(ipaddr, user.getIpaddr()) && StringUtils.equals(userName, user.getUsername()))
            {
                userOnlineList.add(userOnlineService.selectOnlineByInfo(ipaddr, userName, user));
            }
        }
        else if (StringUtils.isNotEmpty(ipaddr))
        {
            if (StringUtils.equals(ipaddr, user.getIpaddr()))
            {
                userOnlineList.add(userOnlineService.selectOnlineByIpaddr(ipaddr, user));
            }
        }
        else if (StringUtils.isNotEmpty(userName) && StringUtils.isNotNull(user.getUser()))
        {
            if (StringUtils.equals(userName, user.getUsername()))
            {
                userOnlineList.add(userOnlineService.selectOnlineByUserName(userName, user));
            }
        }
        else
        {
            userOnlineList.add(userOnlineService.loginUserToUserOnline(user));
        }
    }
    Collections.reverse(userOnlineList);
    userOnlineList.removeAll(Collections.singleton(null));
    return getDataTable(userOnlineList);
}
