Web3j error:Intrinsic gas too low

我是一个以太坊区块链ethereum blockchain开发新手，我一直尝试执行智能合约使用MetaMask和Remix在Chrome浏览器上。

我现在正在尝试使用web3j开发并通过Java部署相同的以太坊智能合约。

但是当我尝试执行我的智能合约时，得到以下错误：error Intrinsic gas too low

Exception in thread "main" java.util.concurrent.ExecutionException: java.lang.RuntimeException: Error processing transaction request: Intrinsic gas too low at java.util.concurrent.CompletableFuture.reportGet(Unknown Source) at java.util.concurrent.CompletableFuture.get(Unknown Source) at com.solartis.bc.Sample.main(Sample.java:44) Caused by: java.lang.RuntimeException: Error processing transaction request: Intrinsic gas too low at org.web3j.tx.ManagedTransaction.send(ManagedTransaction.java:43) at org.web3j.tx.Contract.lambda$deployAsync$24(Contract.java:288)...

我已经通过几个方法来增加gas的值，但是不管我支付多大的值，我仍然会得到同样的错误。

有没有其他人面临同样的问题，我不知道问题在哪儿。下面附上更多细节：

ContractRunner.java

package com.solartis.bc;

    Web3ClientVersion web3ClientVersion = web3.web3ClientVersion().sendAsync().get();
    String clientVersion = web3ClientVersion.getWeb3ClientVersion();
    System.out.println(clientVersion);
    Credentials credentials = WalletUtils.loadCredentials("Mxxxxxxxxe", "C:\\Users\\adheep_m\\AppData\\Roaming\\Ethereum\\keystore\\UTC--2017-07-07T13-52-18.006069200Z--3b0d3fa08f0e0b3da8fe1f8ac0e05861bfdada25");
    System.out.println(credentials.getAddress());

    BigInteger GAS = new BigInteger("30000000");
    BigInteger GAS_PRICE = new BigInteger("20");
    BigInteger ETH = new BigInteger("1");
    //LeisureTravelPolicyHolder contract = LeisureTravelPolicyHolder.deploy(web3,credentials,GAS,GAS_PRICE,ETH,test,test,test,test,test,test,test,test,test).get();

    Token con = Token.deploy(web3,credentials,GAS,GAS_PRICE,ETH).get();
    System.out.println(con.getContractAddress());
}

}

Token.sol:

pragma solidity ^0.4.0;

contract Token { mapping (address => uint) public balances;

function Token() { balances[msg.sender] = 1000000; }

function transfer(address _to, uint _amount) { if (balances[msg.sender] < _amount) { throw; }

 balances[msg.sender] -= _amount;
 balances[_to] += _amount;

} }
