Question

我正在学习基础教程，因为我是新手，并且我有以下配置文件：

public class ConcurrentAlphabet {

    private volatile Thread current;

    public static void main(String[] args) {
        new ConcurrentAlphabet().print(3,
                "ABCDEFGHIJKLMNOPQRSTUVWXYZ".toCharArray());
    }

    public void print(int numberOfThreads, char[] alphabet) {
        Thread[] threads = new Thread[numberOfThreads];

        for (int i = 1; i <= numberOfThreads; i++) {
            int offset = i - 1;
            threads[offset] = new Thread(() -> {
                Thread me = Thread.currentThread();
                Thread next = threads[(offset + 1) % numberOfThreads];

                for (int index = offset; index < alphabet.length; index += numberOfThreads) {
                    synchronized (this) {
                        while (me != current) {
                            try {
                                wait();
                            } catch (InterruptedException e) { /* NOP */ }
                        }

                        System.out.println(me.getName(); + " produced: " + alphabet[index] + ".");
                        current = next;
                        notifyAll();
                    }
                }
            }, "Thread " + i);
        }

        current = threads[0];

        for (Thread t : threads) {
            t.start();
        }
    }

}

然后我在终端

中执行以下命令

input {  
  file {
    path => "D:\elastic\logstash\data\data.csv"
    start_position => "beginning"    
  }
}
filter {  
  csv {
      separator => ","
      columns => ["Date","Open","High","Low","Close","Volume","Adj Close"]
  }
  mutate {convert =&gt; ["High", "float"]}
  mutate {convert =&gt; ["Open", "float"]}
  mutate {convert =&gt; ["Low", "float"]}
  mutate {convert =&gt; ["Close", "float"]}
  mutate {convert =&gt; ["Volume", "float"]}
}
output {  
    elasticsearch {
        action => "index"
        host => "localhost"
        index => "stock"
        workers => 1
    }
    stdout {}
}

它打印出来：

bin\logstash -f logstash-simple.conf

解析文件的其余部分。我错过了什么？它是UTF-8并尝试了EOL UNIX和Windows格式，但都失败了。

您需要修改file输入，如下所示：

  file {
    path => "D:\\elastic\\logstash\\data\\data.csv"
    start_position => "beginning"    
  }

或者像这样

  file {
    path => "D:/elastic/logstash/data/data.csv"
    start_position => "beginning"    
  }

同样在您的过滤器中，mutate/convert中存在拼写错误。它们应该是这样的（即用=>替换=>）：

  mutate {convert => ["High", "float"]}
  mutate {convert => ["Open", "float"]}
  mutate {convert => ["Low", "float"]}
  mutate {convert => ["Close", "float"]}
  mutate {convert => ["Volume", "float"]}

无效的配置logstash文件
