我有下面的类用脚本编写的类.当我编译它时,它错误地说

"src\main\MqttClientWrapper.ts(24,2): error TS1068: Unexpected token. A construct or, method, accessor, or property was expected.".

以下是我的代码.

var mqtt :any = require('mqtt');

export interface IWillMessage {
  topic: string;
  payload: string;
  qos: number;
  retain: string;
}

export interface IMessageReceivedCallBack {
  onMessageReceived(message : string);
}

export interface IMqttOptions {
  clientId: string;
  keepAlive: number;
  clean: string;
  reconnectPeriod: string;
  will: IWillMessage;
}

export default class MqttClientWrapper {

 client : any;

constructor(url: string, mqttOptions : IMqttOptions, messageReceivedCallBack : IMessageReceivedCallBack) {
   client = mqtt.connect(url, mqttOptions);
   client.on('message',function(topic …

我有一个名为processOutbox的方法.我希望它是线程安全的.当一个线程在它时,我不希望另一个线程调用此方法.我已经按照以下方式实现了它.我做得对吗？我的实施有漏洞吗？如果有,请告知我如何解决它.

this.start();
    outboxLock.lock();
    timer = new Timer();
    try{
    timer.scheduleAtFixedRate(new TimerTask() {
            public void run() {
               processOutbox();
            }
        }, 0, period);
    } finally{
        outboxLock.unlock();
    }

我正在使用logback登录我的应用程序，并且在运行该应用程序时，我不断收到以下警告。当我运行单元测试时，它会在每堂课上打印出来！

SLF4J: during the initialization phase. Logging calls during this
SLF4J: phase were not honored. However, subsequent logging calls to these

我已经配置了logback，以在某个位置查找配置文件，下面是日志工厂类的外观。

public class LoggerFactory {

static {
    System.setProperty("logback.configurationFile", System.getProperty("user.dir") + "\\" + "logbackConfig.xml");
}

我有一个Spring Boot应用程序，当通过intellij运行时可以正常工作。但是，当我从罐子中运行它时，出现以下异常。

我有以下代码,我试图转换为Java.

WORD ComputeCRC16(BYTE *data, DWORD data_length)
{
   BYTE *ptr;
   BYTEWORD retval;

    /* Initialize the CRC */
    retval.w = 0xFFFF;

   /* Iterate through the data */
   for (ptr=data; ptr<data+data_length; ptr++)
   {
      // retval.w = IterateCRC16(ptr, retval);
      retval.w = retval.b.hi ^ (ccittrev_tbl[retval.b.lo ^ *ptr]);

   }

   /* Finalize the CRC */
   retval.w = ~retval.w;

   /* Done. */
   return retval.w;
}

下面的内容是什么意思？

retval.w = retval.b.hi ^ (ccittrev_tbl[retval.b.lo ^ *ptr]);

如果我转换为Java,retval应该是一个int吗？如果那么它怎么会有一个名为"w"的成员呢？请告诉我如何将上面的代码转换为Java？

我正在编辑问题,发布我错过的这部分内容.

typedef union
{
  WORD  w;
  struct
  {
     BYTE  lo,
        hi;
   } b;

通常 EXE 版本在 Bundle.wxs 文件中设置。是否可以在编写安装程序后端引擎逻辑的 Bootstrapper 应用程序项目中获取此版本？我使用 WPF 创建了自定义 UI。我需要在用户界面中显示版本。我怎样才能做到这一点？请指教。下面是我的 Bootstrapper 应用程序代码。

    public class MainViewModel : ViewModelBase
    {
        private MINAClient minaClient;

        //constructor
        public MainViewModel(BootstrapperApplication bootstrapper)
        {

            this.IsThinking = false;

            this.Bootstrapper = bootstrapper;
            this.Bootstrapper.ApplyComplete += this.OnApplyComplete;
            this.Bootstrapper.DetectPackageComplete += this.OnDetectPackageComplete;
            this.Bootstrapper.PlanComplete += this.OnPlanComplete;
            this.Bootstrapper.DetectComplete += this.DetectComplete;

            this.Bootstrapper.CacheAcquireProgress += (sender, args) =>
            {
                this.cacheProgress = args.OverallPercentage;
                this.Progress = (this.cacheProgress + this.executeProgress) / 2;
            };
            this.Bootstrapper.ExecuteProgress += (sender, args) =>
            {
                this.executeProgress = args.OverallPercentage;
                this.Progress = (this.cacheProgress + this.executeProgress) / 2;
            };

我有一个字符串,如下所示.

{(firstName1,lastName1,College1,{(24,25)},{(Street,23)},City1,Country1)}

我需要从上面提取细节/值并将它们添加到列表中.我的意思是:

 ["firstName1","lastName1","College1","24","25","Street","23","City1", "country1"]

我怎样才能实现上述目标？我尝试了下面的方法,但不知道如何将所有花括号和括号放入模式中.

private static String flattenPigBag(String pigdata) {
    String s = "";
    Pattern p = Pattern.compile("\\{(.*)}");
    Matcher m = p.matcher(pigdata);
    while (m.find()) {
        s = m.group(1);
        System.out.println("answer : " + s);
    }
    return s;
}

我编写了一个 bash 脚本，它按名称获取参数并读取键值对中的值。下面是我如何运行脚本的示例。

 sh test.sh param1='a' param2='b'

然后，我在脚本中引用 $param1 和 $param2 等输入参数。下面是我为此编写的脚本。

for item in $@; do
case $item in
(*=*) eval $item;;
esac
done

但是当参数值中有空格时，它只取空格之前的部分。

 param3='select * from'

只会将“select”分配给 param3 而不是整个字符串。我怎样才能实现这个目标？任何帮助将非常感激。

伊尼安回答后

for item in $@; do
case "$item" in
(*=*) eval "$item";;
esac
done

我有下面的 ObjectNode。

handlerObjectNode -> {"Info":{"Brand":{"BrandName":"TOP OF THE WORLD"}}}

我有另一个以下格式的 ObjectNode。

fieldObjects -> {"Description":"REGULAR BR"}

如何从上面两个创建下面的 ObjectNode？

{
   "Info": {
       "Brand": {
           "BrandName": "TOP OF THE WORLD"
       }
   "Description": "REGULAR BR"
   }
 }

我尝试了下面的代码。

handlerObjectNode.setAll(fieldObjects);

但它会产生以下 ObjectNode。

{
   "Info": {
       "Brand": {
           "BrandName": "TOP OF THE WORLD"
       }
   },
   "Description": "REGULAR BR"
 }

我正在使用 Jackson 的 com.fasterxml.jackson.databind.node.ObjectNode 。任何帮助将非常感激。
