                        |__/              

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()
