如何在BIRT报告中获取geoLocation

Question

我正在使用BIRT报告工具生成报告。我需要显示与经度和纬度相对应的地理位置名称。在报告中，我想在表格中显示对应的地理位置名称（即：使用Google Map API）。我不需要显示Google地图。如何在BIRT报告中执行此操作。

Answer 1

You can insert the jsfiddle you mentionned as it is in a birt text element, see a live example of google API embedded in a BIRT report here .

Though it is important to note it makes use of a client-side geocoding API, whereas usual BIRT scripts are server-side javascripts. This implies limitations:

To introduce a client-side javascript in BIRT, we have to:

• Insert a BIRT text element in the report
• Set the type to "HTML" in the dropdown at the top of the element
• Insert the HTML markup & Javascript code as text content

That's quite easy, but when we get a such content through a client-side javascript, it won't be available for exports PDF, Powerpoint etc: it only appears in HTML format.

In order to make it available for other formats such PDF, we have to use a java geocoder API such google's , and provide relevant "jar" libraries to the BIRT engine as explained here .

Some geocoding java API are free and/or open source but the geocoding services might be limited. Read carefully the terms of use.

据我所知，可以从BIRT工具生成的报告中调用外部Java包，因此，我的想法是您可以编写一个Java方法来调用Google地理编码API （可以从经度和纬度解析地理位置名称） ，然后从report调用java方法。
