Java 实现在线翻译功能 调用微软Bing API
Java封装的百度翻译Api
http://www.pocketdigi.com/20130626/1123.html
百度没有提供直接可用的翻译api,有道倒是有，不过只能英译中，不支持其他语言。但是百度自己有个翻译服务，http://fanyi.baidu.com/，使用的时候，页面并不会刷新，而是用ajax调用了一个翻译API,分析了一下，这个api地址是http://fanyi.baidu.com/transapi，接受三个参数，from,to,query分别是源语言，目标语言，待翻译文本。
简单封装了一下,默认中译英，要改其他语言，可以把参数提出来：
