Porting python PKCS1_v1_5 encryption code to java but java code not work

Question

I have a backend,which receives codes and returns true or false.
I send it codes using my python encryption,it returns true(the result varible):

from Cryptodome.Cipher import PKCS1_v1_5
from Cryptodome.PublicKey import RSA
import base64

prsa = RSA.importKey('''-----BEGIN RSA PUBLIC KEY-----
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
-----END RSA PUBLIC KEY-----''')
pcipher = PKCS1_v1_5.new(prsa)
result=base64.b64encode(pcipher.encrypt(bytes))

But my java encryption always return false:

public static String encrypt(byte[] bytes, String publicKeyFilePath)
    throws Exception {
  byte[] keyBytes = Files.readAllBytes(Paths.get(publicKeyFilePath));
  X509EncodedKeySpec keySpec = new X509EncodedKeySpec(keyBytes);
  KeyFactory keyFactory = KeyFactory.getInstance("RSA");
  Key key = keyFactory.generatePublic(keySpec);
  Cipher cipher = Cipher.getInstance("RSA/ECB/PKCS1PADDING");
  cipher.init(1, key);
  byte[] result = cipher.doFinal(bytes);
  return java.util.Base64.getEncoder().encodeToString(result);
}

Both java and python codes can be well decrypted by my java decryption codes(I have private key).
I have tryed different kinds of cipher,such as:

Cipher cipher = Cipher.getInstance("RSA/None/PKCS1Padding");

And trying to set provider:

Cipher cipher = Cipher.getInstance("RSA/None/PKCS1Padding",new org.bouncycastle.jce.provider.BouncyCastleProvider());

But all return false.I am confused about the "PKCS1_v1_5",for don't know which kind of padding it is,and what is the right code porting to java?
