再写一个自动任务，同步钱包高度，查看每个交易记录里的接受地址是否为分配给用户的地址，是的话就代表用户充值了。

/**
 * 区块扫描任务

 * @author xhl
 * @create 2017/10/28
 **/
public class CoinScanJob {
    @Resource
    private CoinUsdtService coinUsdtService;

    public void run(){
            usdtJob();
    }
    /**
     * USDT处理
     */
    private void usdtJob(){
        //这一步获取自己系统存的钱包同步的高度
        int blockParseedCount = coinParseService.getBlockHeight(CoinConstant.COIN_USDT);
        if(blockParseedCount == 0)return;
        //获取钱包的高度
        int blockCount = coinUsdtService.getBlockCount();

        log.info("bte当前高度是：{} 处理记录高度：{}",blockCount,blockParseedCount);
        if(blockCount>blockParseedCount){
            //还有没有处理完的区块， 继续处理
            int index = blockParseedCount+1;
            while(index <= blockCount){
                try {
                    if(coinUsdtService.parseBlock(index)){
                        index++;
                    }else{
                        break;
                    }
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
            if(index == blockCount){
                //所有区块都已经处理完
                coinParseService.updateBlockRecord(CoinConstant.COIN_USDT, index);
            }else{
                coinParseService.updateBlockRecord(CoinConstant.COIN_USDT, index-1);
            }
        }
    }
}

1.HttpUtil.jsonPost  工具类若需要可加我qq！
