Install Java and Maven

示例程序依赖 Java 1.8 运行时环境以及Maven，可以通过如下命令确认是否已经安装。

$ mvn -version
Apache Maven 3.5.3 (3383c37e1f9e9b3bc3df5050c29c8aff9f295297; 2018-02-25T03:49:05+08:00)
...
Java version: 1.8.0_161, vendor: Oracle Corporation

Download The Sample Program

The default sample program has configured the jar package. If you are creating a new project, you need to manually import the jar package.

With the idea IDE, the sample program’s final directory structure is as follows:
