这是因为Angular中使用的Crypto库和Java中使用的BCrypt库加密算法不同造成的。解决方法是在Java中使用与Angular中Crypto库相同的加密算法，或在Angular中使用与Java中BCrypt库相同的加密算法。

以下是在Java中使用与Angular中Crypto库相同的加密算法的示例：

import javax.crypto.Cipher;
import javax.crypto.spec.IvParameterSpec;
import javax.crypto.spec.SecretKeySpec;
import org.apache.commons.codec.binary.Base64;

public class CryptoUtil {

  public static String encrypt(String key, String initVector, String value) {
    try {
      IvParameterSpec iv = new IvParameterSpec(initVector.getBytes("UTF-8"));
      SecretKeySpec skeySpec = new SecretKeySpec(key.getBytes("UTF-8"), "AES");

      Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5PADDING");
      cipher.init(Cipher.ENCRYPT_MODE, skeySpec, iv);

      byte[] encrypted = cipher.doFinal(value.getBytes());
      return Base64.encodeBase64String(encrypted);
    } catch (Exception ex) {
      ex.printStackTrace();
    }

    return null;
  }

  public static String decrypt(String key, String initVector, String encrypted) {
    try {
      IvParameterSpec iv = new IvParameterSpec(initVector.getBytes("UTF-8"));
      SecretKeySpec skeySpec = new SecretKeySpec(key.getBytes("UTF-8"), "AES");

      Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5PADDING");
      cipher.init(Cipher.DECRYPT_MODE, skeySpec, iv);

      byte[] original = cipher.doFinal(Base64.decodeBase64(encrypted));

      return new String(original);
    } catch (Exception ex) {
      ex.printStackTrace();
    }

    return null;
  }
}

在Angular中使用与Java中BCrypt库相同的加密算法的示例：

import * as bcrypt from 'bcryptjs';

const saltRounds = 10;

export function hashPassword(password: string): Promise {
  return bcrypt.hash(password, saltRounds);
}

export function comparePassword(password: string, hash: string): Promise {
  return bcrypt.compare(password, hash);
}
