VSOMEIP-配置文件-json文件

首先我们得看一下环境变量VSOMEIP_CONFIGURATION,根据用户手册

* `VSOMEIP_CONFIGURATION`: vsomeip uses the default configuration file `/etc/vsomeip.json`
   and/or the default configuration folder `/etc/vsomeip`. This can be overridden by a
   local configuration file `./vsomeip.json` and/or a local configuration folder `./vsomeip`.
   If `VSOMEIP_CONFIGURATION` is set to a valid file or directory path, this is used instead
   of the standard configuration (thus neither default nor local file/folder will be parsed).
  • vsomeip默认使用配置文件 /etc/vsomeip.json或者包含配置文件的文件夹/etc/vsomeip,如果当前目录存在 /etc/vsomeip.json或者包含配置文件的文件夹/etc/vsomeip,优先使用当前目录的配置文件,用户可通过配置VSOMEIP_CONFIGURATION环境变量覆盖当前和默认的配置文件。

我们来看一下配置文件内容,以上篇文章的配置文件为例:
