将企业微信提供的linux和windows的sdk文件解压，将里面的dll、so、java文件放到src/main/java目录下，如下图所示

参考https://zhuanlan.zhihu.com/p/37686736x修改pom文件将dll和so文件打包进jar

然后更改Finance的static代码块：

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;
}
