英文:
Java Maven Spring Boot UnsatisfiedLinkError when spring-boot:run with own library copied at project
问题
我有一个默认的jersey项目，从https://start.spring.io/下载，我在其中添加了一个lib文件夹，里面有一个在c ++中编译的库，通过JNI进行调用。在Eclipse中将“lib”目录添加到类路径中，并通过“Java Application”选项完美运行。当尝试使用maven命令`mvn spring-boot:run`直接运行时，尝试加载库时会出现错误。我的pom文件如下：

当使用mvn spring-boot:run命令直接运行时，出现的错误是：

I have a default jersey project, downloaded from https://start.spring.io/ to which I added a lib folder and in it a library compiled in c ++ to be called via JNI. In Eclipse add the "lib" directory to the classpath and it runs perfectly through the "Java Application" option. When trying to run direct with the maven command `mvn spring-boot:run`, it gives me error when trying to load the library. my pom file is:

The error, only when `mvn spring-boot:run` is:
