Question

我从我的网络服务器返回JSON，格式如下：

var results = (
    from o in Orders
    group o by o.CustomerId into og // create a grouping of orders by customerID
    orderby og.Count() descending // sort by number of orders in each grouping
    join c in Customers on og.Key equals c.Id // og.Key is the grouping Key (CustomerId)
    select new MostActive
    {
        FirstName = c.FirstName,
        LastName = c.LastName,
        Id = c.Id,
        Count = og.Count()
    }).Take(10);

我如何在Java中解析JSON以获得第一个键和该键的第一个值？所以在上面的例子中，输出应该是：

{"success":false,"errors":{"username":["Invalid username","Username too short"],"password":["Invalid password"]}}

我目前的代码如下：

username
Invalid username

也许这样的事情可以帮助你，我不完全确定我是否理解你的问题：

@Override
