命令行编译合约

运行以下命令行，编译 hello.sol 合约并得到编译字节码结果和合约 ABI：

solcjs --bin Transfer.sol -o ../bin && solcjs --abi Transfer.sol -o ../bin

合约生成 java 文件

web3j solidity generate -b  bin文件  -a  abi文件  -p 包名 -o 输出路径

web3j solidity generate --javaTypes  ../bin/Transfer_sol_Transfer.bin  ../bin/Transfer_sol_Transfer.abi  -p com.ionc.demo -o ./

web3j solidity generate --javaTypes  ../bin/Transfer_sol_Transfer.bin  ../bin/Transfer_sol_Transfer.abi  -p com.ionc.demo -o ../src/main/java/ 

solcjs --bin IoncTest.sol -o ../bin
solcjs --abi IoncTest.sol -o ../bin

solcjs --bin ./contracts/Transfer.sol -o ./bin

solcjs --abi ./contracts/Transfer.sol -o ./bin

web3j solidity generate --javaTypes ./
