--------------------- 2020年12月更新-------------------------
功能一:
南京市东南大学至新街口区域,道路车速获取的代码.
核心代码:
src/main/entity/GdNavLinkNJ.java
src/main/gaode/GetNavNJ.java
--------------------- end -------------------------

--------------------- 2020年1月更新-------------------------
功能二:
利用高德路径规划接口获取路网
核心代码:
src/main/entity/GdNavLink_hibernate.java
src/main/gaode/GetNav.java
"SQL部分.sql"
------------------------ end -------------------------

概述----------
语言: JAVA
项目管理方式: maven
数据库: ORACLE
持久化框架: hibernate. 使用该持久化框架的目的是方便大家切换数据库为自己的偏好(如postSQL/MySQL等)

如何使用----------

  1. 构建maven工程
  2. maven无法自动添加oracle数据库的jdbc驱动,需要手动安装该驱动(ojdbc6-11.2.0.1.0.jar),oracle版权原因, 我就不上传这个jar包了, 需要请自行百度,联系我也行.
  3. 在main/resources/META-INF/persistence.xml中修改数据库连接参数
  4. 在getHttpReq方法中填入你自己申请的KEY
  5. SQL部分。仅功能二用到,功能一不用。在数据库中新建表GD_NAV_POINT和GD_NAV_TRAFFIC,详见“SQL部分.sql”,可以用你自己的方法构造OD点对,也可以参照公众号教程中的操作实例
  6. 运行: 功能一: 运行src/main/java/gaode/GetNavNJ.java 中的main方法; 功能二: 运行src/main/java/gaode/GetNavTrafficHibernate.java中的main方法.
  7. SQL部分(仅功能二需要运行)。回到“SQL部分.sql”, 进行连通性和拓扑性的批量处理。
  8. 最后在数据库中导出表GD_NAV_TRAFFIC_2, 即为最终路网。

建议:

  1. 建议先学习功能二, 再学习功能一. 不然你很难理解功能一每个步骤的意图(尽管有注释).
  2. 看代码时一定要结合着公众号文章教程, 原因同上.
