用Java获取用户当前的经度和纬度(Get user's current latitude and longitude in Java)

用Java获取用户当前的经度和纬度(Get user's current latitude and longitude in Java)

我在这里看到了很多关于Java的问题，但我看到的每一个问题似乎都是以Android为中心的：我需要一种方法来获取用户当前的经纬度来自他们的电话，而不是移动设备。 我知道这在C＃中是可行的，但我不确定如何在Java中完成它。 我之前使用过Google Maps的restful API：但是，它想要一个地址作为输入，我只想获得用户当前的lat / lon，我觉得这比拨打Google更简单。 任何帮助将不胜感激。

I see this question asked a lot here for Java, but every single one I see seems to be Android-centered: I need a way of getting the user's current latitude and longitude when they call is coming from a computer, not a mobile device. I know that this is doable in C#, but I'm not sure how exactly to do it in Java. I've used Google Maps' restful API before: however, it wants an address as input, and I just want to get the user's current lat/lon, which I feel is simpler than making a call to Google. Any help would be greatly appreciated.

Java目前不提供通用的独立于平台的API来获取位置。 但是，可能存在特定于平台的方式。

台式机上的大多数实现都将通过IP地址进行地理定位; 您可以使用Java提供的这些服务（ 在Java中获取地理位置的最佳方式 ）。 但是，如果操作系统提供更通用的API，则可以利用任何GPS硬件。

这里有Gnome提供的库的详细信息，以及KDE支持计划的编写。

Java doesn't currently provide a general platform-independent API to get location. However, there may be platform-specific ways.

Most implementations on a desktop machine will geolocate via IP address; you can use these services from Java (Best way to get geo-location in Java). However, if operating systems provide a more general API, it can take advantage of any GPS hardware.

There's detail here of a Gnome-provided library, and also a write-up of plans for support in KDE.
