How to Use Dynamic Private Key to Sign Transaction when Call Smart Contract Through web3j_openapi ? #1406

We would like to expose the smart contracts functions and event to auto-generated RESTFul API, web3j's Web3j-OpenAPI generator is the tool I am looking for.

But I realize the the the private key is hard code via configuration environment variable WEB3J_PRIVATE_KEY, but in my case, I need each transaction need to sign by different user's private key or wallet before send the transaction to chain. is it a easier way for web3j-openAPI to implement this, please advise.

@bao1018 Hey I think there should be a way to configure that through code I will have a look. There are ways to pass these as a config file which can take the form of YAML or JSON. You might be able to work with that have a look here.
