JAVA集成-精臣打印机打印取件码

简述：通过扫码枪进行扫描传参或者模拟调用接口都可;
代码可修改；

@Slf4j
@Component
public class SocketConfig {
    private static String billNo;

}

@Data
public class MakeParamDTO implements Serializable {
    //物流单号
    private String billNo;
    //取件码
    private String code;
}

调用打印机：

@Resource
private final WebSocketClient pickUpCodeClient;
public final static AtomicBoolean commitJobInProgress = new AtomicBoolean(false);//用来检测上一个提交的任务有没有打印完成，进行阻塞
public static final LinkedList<MakeParamDTO> dtos = new LinkedList<>();//将数据先保存起来，先进先出

 @PostMapping("/handleCode")
    public void handleCode(@RequestBody MakeParamDTO dto) {
        log.info("取件码回调成功");
       dtos.add(dto);
        while (commitJobInProgress.get()) {
            try {
                Thread.sleep(100); // 等待一段时间后重试
            } catch (InterruptedException e) {
                Thread.currentThread().interrupt();
                log.error("线程断开了");
            }
        }
        log.info("线程名： " + Thread.currentThread().getName());
        commitJobInProgress.set(true);
        MakeParamDTO first = dtos.getFirst();
        SocketConfig.setBillNo(first.getBillNo());
        SocketConfig.setCode(first.getCode());
        dtos.removeFirst();
        //提交打印任务
        pickUpCodeClient.send("{\"apiName\":\"startJob\",\"parameter\":{\"printDensity\":3,\"printLabelType\":1,\"printMode\":1,\"count\":1}}");
        log.info("取件码回调结束");
    }
