BloomBerg Java API调用实例

首先，先问度娘介绍一下Bloomberg

彭博(Bloomberg)是全球商业、金融信息和财经资讯的领先提供商，由纽约市市长迈克尔·布隆伯格于1981年创立的，总部位于美国纽约市曼哈顿，现有超过1万3千员工，业务遍及全球185多个国家与地区。2012年彭博资讯集团全球营业收入达76亿美元，成为全球最大的财经资讯服务提供商。

我来补充总结几句，相比路透（即路透社的那个路透），彭博可能让人觉得有点陌生，不过作为全球与路透不相上下的信息提供商，在金融领域，是使用非常普遍的。

 

其实Bloomberg和Reuters的Extra3000(现在的EIKON)一样，都在客户端提供了非常好用的Excel插件工具用来抓取刷新各种信息。但是数据抓取了之后，还只是停留在Excel上，并不能为系统所直接使用，因此怎么把数据抓到系统中，成为了一个需要解决的问题。

 

有幸，当年通过不断搜索，发现Bloomberg竟然有着完整的JAVA SDK,还算擅长这种语言的我自然就想到了直接调用该API来解决面临的实际问题：

当然首先该SDK的首要条件是需要你有一台可以使用的Bloomberg客户端；

下载完成的SDK 如下：

还是比较显而易见的，在工程中引入bin包中的 jar,examples目录有相关的查询实例，doc文档有详细的说明；

以下以查询CHF,TWD,SGD,NZD的开盘价为例（修改自官方Example 中的SimpleSubscriptionExample ）

            }

}

还是很简单的就可以调用了，接下来需要插入数据库或者使用WebServcie插入数据都可以，当然此类实现的方法多种多样，此文仅为抛砖引玉，为大家提供思路。
