https://zhuanlan.zhihu.com/p/37686736 参考这个，在maven打包的时候将dll和so文件打进jar中，然后讲加载文件的代码改一下： static { if (isWindows()) { String path = Finance.class.getResource("").getPath().replaceAll("%20", " ").replaceFirst("/", "").replace("/", "\\\\"); //加载顺序不要变 System.load(path.concat("libeay32.dll")); System.load(path.concat("libprotobuf.dll")); System.load(path.concat("ssleay32.dll")); System.load(path.concat("libcurl.dll")); System.load(path.concat("WeWorkFinanceSdk.dll")); } else { String path = Finance.class.getResource("").getPath(); System.load(path.concat("libWeWorkFinanceSdk_Java.so")); } } public static boolean isWindows() { String osName = System.getProperties().getProperty("os.name"); System.out.println("current system is " + osName); return osName.toUpperCase().indexOf("WINDOWS") != -1; }
