Java Maven Spring Boot UnsatisfiedLinkError，当spring-boot：运行时在项目中复制了自己的库

Question

我有一个默认的jersey项目，从https://start.spring.io/下载，在其中添加了一个lib文件夹，并在其中添加了一个用c ++编译的库，可通过JNI进行调用。在Eclipse中，将“ lib”目录添加到类路径中，并且它可以通过“ 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，在尝试加载库时出现错误。我的pom文件是：

错误，仅当运行maven时：

java.lang.UnsatisfiedLinkError: no ExtractDataDicom in java.library.path
        at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1867) ~[na:1.8.0_121]
