Ethereum Solidity Method signature Util

When using solidity to write contract code, we need to call the contract. We need to know the contract address, contract abi, bin and other files. Most importantly, we need to know the method signature in the contract. This tool jar can execute one click to generate the method signature of all the methods in the contract, so that we can check the proofreading when calling back-end. No need to use Remix to write a method to view the method signature of this contract.
