(java 功能代码) 百度翻译接口

java 解析json相关

一json-lib.jar开发包使用依赖包
                                json-lib.jar开发包使用需要依赖包以下开发包: 
                               * jakarta commons-lang 2.4
                               * jakarta commons-beanutils 1.7.0
                               * jakarta commons-collections 3.2
                               * jakarta commons-logging 1.1.1
                               * ezmorph 1.0.6
