我可以在没有ExecutorService的情况下使用Callable线程吗？我们可以使用Runnable的实例和没有ExecutorService的Thread的子类,这个代码可以正常工作.但是这段代码始终如一:

public class Application2 {

    public static class WordLengthCallable implements Callable {
        public static int count = 0;
        private final int numberOfThread = count++;

        public Integer call() throws InterruptedException {
            int sum = 0;
            for (int i = 0; i < 100000; i++) {
               sum += i;
            }
            System.out.println(numberOfThread);
            return numberOfThread;
       }
   }
   public static void main(String[] args) throws InterruptedException {
       WordLengthCallable wordLengthCallable1 = new WordLengthCallable();
       WordLengthCallable wordLengthCallable2 = new WordLengthCallable();
       WordLengthCallable wordLengthCallable3 = new WordLengthCallable();
       WordLengthCallable wordLengthCallable4 = new …

我做错了什么？我尝试使用Spring mvc和JSON.当我尝试调试我的代码时,我看起来javascript工作,但不适用于控制器.在浏览器中,我收到错误415不支持的媒体类型.

脚本:

$(document).ready(function() {
  $('#newSmartphoneForm').submit(function(event) {

      var producer = $('#producer').val();
      var model = $('#model').val();
      var price = $('#price').val();
      var json = { "producer" : producer, "model" : model, "price": price};

    $.ajax({
        url: $("#newSmartphoneForm").attr( "action"),
        data: JSON.stringify(json),
        type: "POST",

        beforeSend: function(xhr) {
            xhr.setRequestHeader("Accept", "application/json");
            xhr.setRequestHeader("Content-Type", "application/json");
        },
        success: function(smartphone) {
            var respContent = "";

            respContent += "<span class='success'>Smartphone was    created: [";
            respContent += smartphone.producer + " : ";
            respContent += smartphone.model + " : " ;
            respContent += smartphone.price + …
