7.代码下载、编译、打包

代码下载请访问 github上的 witpool/wit-neptune

导入工程文件、编译、打包步骤如下：

eclipse 导入maven工程

导入maven工程

maven打包

8.启动和ut步骤

启动应用：java -jar wit-rest-1.0.jar

ut步骤：

(1). 下载wisdomtool rest client

(2). 双击 jar包 restclient-1.1.jar 启动工具

导入测试用例文件：

关于wisdomtool rest client更多的使用帮助，请参考github wisdomtool/rest-client
