【围观】麒麟芯片遭打压成绝版，华为亿元投入又砸向了哪里？>>>
一、安装web3j $ brew tap web3j/web3j $ brew install web3j $ web3j _ _____ _ _ | | |____ (_) (_) __ _____| |__ / /_ _ ___ \ \ /\ / / _ \ '_ \ \ \ | | | / _ \ \ V V / __/ |_) |.___/ / | _ | || (_) | \_/\_/ \___|_.__/ \____/| |(_)|_| \___/ _/ | |__/ Usage: web3j version|wallet|solidity ...
二、安装solc
sudo npm install -g solc
三、生成.bin和.abi
solcjs /Users/shijun/Desktop/truffleWorkspace/eCommerce/contracts/ConfirmOrder.sol --bin --abi --optimze -o/Users/shijun/Desktop/truffleWorkspace/eCommerce_out
四、生成.java
$ web3j solidity generate --solidityTypes /Users/shijun/Desktop/truffleWorkspace/eCommerce_out/_Users_shijun_Desktop_truffleWorkspace_eCommerce_contracts_ConfirmOrder_sol_ConfirmOrderContract.bin /Users/shijun/Desktop/truffleWorkspace/eCommerce_out/_Users_shijun_Desktop_truffleWorkspace_eCommerce_contracts_ConfirmOrder_sol_ConfirmOrderContract.abi -o /Users/shijun/Desktop/truffleWorkspace/eCommerce_out -p www.membersheep.hk.web3j
=================================================================
web3j solidity generate --solidityTypes /Users/shijun/Desktop/truffleWorkspace/sheepCoin_out/_Users_shijun_Desktop_truffleWorkspace_sheepCoin_tokenecr20_sol_TokenERC20.bin /Users/shijun/Desktop/truffleWorkspace/sheepCoin_out/_Users_shijun_Desktop_truffleWorkspace_sheepCoin_tokenecr20_sol_TokenERC20.abi -o /Users/shijun/Desktop/truffleWorkspace/sheepCoin_out -p Shpcoin.web3j
web3j solidity generate --solidityTypes /Users/shijun/Desktop/truffleWorkspace/sheepCoin_out/_Users_shijun_Desktop_truffleWorkspace_sheepCoin_tokenecr20_sol_tokenRecipient.bin /Users/shijun/Desktop/truffleWorkspace/sheepCoin_out/_Users_shijun_Desktop_truffleWorkspace_sheepCoin_tokenecr20_sol_tokenRecipient.abi -o /Users/shijun/Desktop/truffleWorkspace/sheepCoin_out -p Shpcoin.web3j

五、将java文件放入项目
六、启动私有链

miner.start(1)
miner.stop()
