我从https://github.com/web3j/web3j-spring-boot-starter添加了 web3j 的依赖项
然后创建了一个服务并编写了：
@Service
public class Web3jServiceImpl {
@Autowired
private Web3j web3j;
public void getBlockNumber() {
logger.debug("get block number method");
web3j.blockObservable(false).subscribe(block -> {
logger.debug("block number: {}", block.getBlock().getNumber() + " has just been created");
}, Throwable::printStackTrace);
}
public void getTxInfo(){
web3j.transactionObservable().subscribe(tx -> {
logger.debug("transaction info: {}",tx);
}, Throwable::printStackTrace);
}
}
当在以太坊的私有区块链中创建任何块时，我正在获取块号，但是在交易中可观察到的BigInteger out of int range异常。
日志是：
