海康威视api提供依赖（放的位置要和下面对应）

 在模块中导入依赖

<!--海康威视坐标依赖--><dependency><groupId>com.hikvision.ga</groupId><artifactId>artemis-http-client</artifactId><version>1.1.8</version><scope>system</scope><systemPath>${project.basedir}/src/main/resources/gal/artemis-http-client-1.1.8.jar</systemPath></dependency>

以下是我在对接时碰到的坑，由于项目中没有httpclient的依赖导致视频流一直拿不到总是报出找不到httpclient接口（因为海康的接口中调去了这个接口）需要导入

<dependency><groupId>org.apache.httpcomponents</groupId><artifactId>httpclient</artifactId><version>4.5.13</version>
</dependency>
