聊聊被AI坑到的经历

List<TodoTask> result = forkJoinPoolFactoryBean.getObject().submit(new Callable<List<TodoTask>>() {
            @Override
            public List<TodoTask> call() throws Exception {
                return IntStream.rangeClosed(1, 20).parallel().mapToObj(i -> {
                    log.info("thread:{}", Thread.currentThread().getName());
                    return new TodoTask(i, "name"+i);
                }).collect(Collectors.toList());
            }
        }).get();

IntStream.rangeClosed(1, 20).parallel().executor(customThreadPool).mapToObj(i -> {
                    log.info("thread:{}", Thread.currentThread().getName());

To extract fields from log files using Filebeat and separate them using the pipe symbol (|), you can use the grok processor in the Filebeat configuration file.

Here's an example of how you can configure Filebeat to collect log files and extract fields using the pipe symbol:

Open the Filebeat configuration file. The location of this file may vary depending on your system. Common locations include /etc/filebeat/filebeat.yml or /etc/filebeat/filebeat.yaml.

Find the filebeat.inputs section in the configuration file. This is where you define the log files to collect.

Add the following configuration for each log file you want to collect:

- type: log
  paths:
    - /path/to/your/logfile.log
  processors:
    - grok:
        patterns:
          - '%{WORD:field1}\|%{WORD:field2}\|%{WORD:field3}'
        field: "message"
In this example, replace /path/to/your/logfile.log with the actual path to your log file. The grok processor is used to extract fields from the log message using the pipe symbol (|). The patterns option specifies the grok pattern to use for field extraction, and the field option specifies the field to apply the processor to.

Save the configuration file and restart Filebeat for the changes to take effect.
With this configuration, Filebeat will collect the log file and extract fields from the log message using the pipe symbol (|). The extracted fields will be available in the output, and you can send them to Elasticsearch or any other output you have configured in Filebeat.

I hope this helps! Let me know if you have any further questions.
