我的需求就一个文件，也没有什么依赖。所以调用应该没什么问题。
打包Jar包
目录结构: com\commonsdk\utils\RSAUtils.java
先生成class文件(需要运行在java代码同目录下)
javac -encoding utf-8 RSAUtils.java
删除java代码文件，保留class文件
然后返回到com同级目录运行，就能生成RSAUtils.jar文件
jar -cvf RSAUtils.jar com
调用jar包
import jpype
import time
def get_rsa_sign():
jvmPath = jpype.getDefaultJVMPath()
jpype.startJVM(jvmPath, "-ea", "-Djava.class.path=RSAUtils1.jar")
JDClass = jpype.JClass("com.commonsdk.utils.RSAUtils")
jd = JDClass(1024)
key = str(jd.getKey(str(int(time.time()))))
print(key)
signature = str(jd.encode(key))
jpype.shutdownJVM()
return signature
if __name__ == '__main__':
print("rsa 签名结果:",get_rsa_sign())
因为java代码没什么依赖，所以也没遇到什么坑，试了试就过了
aardio调用java
aardio应该是需要32位的java，因为即使设置了环境变量，依然会自动下载java。但是代码设置的java下载地址已经失效了，抓个包看到地址是：https://mirrors.tuna.tsinghua.edu.cn/AdoptOpenJDK/8/jre/x32/windows/OpenJDK8U-jre_x86-32_windows_hotspot_8u312b07.zip，
去掉后面的文件名访问链接，发现只是版本变化了而已，搜一下aardio的源码，改一下地址和路径即可
调用jar包的代码大致和Python的一样，都是使用的jvm虚拟机
import console;
import java;
var jvm = java();
jvm.addClassLoaderUrl("D:\jar");
RSAUtils = jvm.import( "com.commonsdk.utils.RSAUtils");
var rsa = RSAUtils(1024);
var String = jvm.import( "java.lang.String");
var t = tostring(tonumber(time()));
var key = rsa.getKey(t);
console.log("key: ", key);
console.log("signature: ", rsa.encode(key))
console.pause();
