jmeter的beanshell无法导入jar包

[木縰]

beanshell中使用第三方jar包（web3j）无法使用，报错如下

我将jar包放在相关文件夹中，配置了配置文件，也试过放在lib/ext中，以下是相关代码

import org.bouncycastle.util.encoders.Hex;
import org.web3j.crypto.Credentials;
import org.web3j.crypto.Hash;
import org.web3j.crypto.Keys;
import org.web3j.crypto.Sign;


import org.bouncycastle.util.encoders.Hex;



// 钱包私钥
String priKey = "xxxxx";
// 钱包地址
String walletAddress = "0xxxxxxxxxxxx";

// 原文
String content = vars.get("message");

// 原文摘要字节数组
byte[] contentHashBytes = Hash.sha3(content.getBytes());

// 原文摘要16进制字符串
String contentHashHex = Hex.toHexString(contentHashBytes);

Credentials credentials = Credentials.create(priKey);
Sign.SignatureData signMessage = Sign.signPrefixedMessage(contentHashBytes, credentials.getEcKeyPair());
System.out.println(Hex.toHexString(signMessage.getR()));
System.out.println(Hex.toHexString(signMessage.getS()));
System.out.println(Hex.toHexString(signMessage.getV()));

// 签名后的字符串
String signStr = "0x" + Hex.toHexString(signMessage.getR()) + Hex.toHexString(signMessage.getS()) + Hex.toHexString(signMessage.getV());
System.out.println("signStr=" + signStr);
log.info(signStr);

钱包地址，私钥均隐藏可以根据自己实际填写，以上代码是web3进行签名的操作。

 

希望有大佬能够给一些解决方案，不胜感激
