我的应用程序中有一个类。

public Robot implements Callable<String> {
@Override
    public String call() {
        synchronized (monitor) {
            while (true) {
                /// doing somthing
                monitor.wait(15000L)
            }
        }
    }
}

然后有一个启动 Robot 对象的服务类

List<Robot> robots = <10000 роботов>
ThreadPoolTaskExecutor threadPoolTaskExecutor = new ThreadPoolTaskExecutor();
threadPoolTaskExecutor.setMaxPoolSize(robots.size());
threadPoolTaskExecutor.setCorePoolSize(robots.size());
threadPoolTaskExecutor.initialize();

for (Robot robot : robots) {
    try {
         Future<String> result = threadPoolTaskExecutor.submit(robot);
    } catch (Exception e) {
         log.warn("", e);
    }
}

如果我像这样运行它，我会得到

[70,174s][warning][os,thread] Failed to start thread - pthread_create failed (EAGAIN) for attributes: stacksize: 1024k, guardsize: 0k, detached.
org.springframework.web.util.NestedServletException: Handler dispatch failed; nested exception is java.lang.OutOfMemoryError: unable to create native thread: possibly out of memory or process/resource limits reached

关键是每个机器人每 15 秒执行一次动作并入睡。

动作本身只需要几分之一秒。

有一个想法是采用一个线程池，并在一个循环中，每 15 秒一次，通过它运行一个机器人列表。但是我有一个条件，即机器人执行第一个动作时有随机延迟，所有其他重复动作在前一个动作之后的间隔约为 15 秒。而且我不知道该怎么做...

有一个类：

@Component
public class EventPublisherImpl implements EventPublisher {

    private final Logger log = LoggerFactory.getLogger(this.getClass());

    private List<EventListener> listeners = new ArrayList<>();

    @Override
    public void addListener(EventListener toAdd) {
        listeners.add(toAdd);
    }

    @Override
    public void removeListener(EventListener toRemove) {
        listeners.remove(toRemove);
    }

    public void publicEvent(AmiObject amiObject) {
        if (listeners != null && !listeners.isEmpty()) {
            Iterator<EventListener> iterator = listeners.iterator();
            while (iterator.hasNext())
                synchronized (iterator) {
                    EventListener eventListener = iterator.next();
                    if (eventListener != null) {
                        eventListener.publicEvent(amiObject);
                    }
                }
        }
    }
}

EventListeners 从不同的线程添加到它。

因此，在启动时，会出现错误：

Exception in thread "Thread-1" java.util.ConcurrentModificationException
    at java.base/java.util.ArrayList$Itr.checkForComodification(ArrayList.java:1042)
    at java.base/java.util.ArrayList$Itr.next(ArrayList.java:996)

    at ...ConnectorImpl.run(ConnectorImpl.java:92)
    at java.base/java.lang.Thread.run(Thread.java:834)

并指向线

EventListener eventListener = iterator.next();

帮助配置 Spring。

控制器

@Controller
@RequestMapping("/*")
public class IndexController {

    private final Logger log = LoggerFactory.getLogger(this.getClass());

    @RequestMapping(method = RequestMethod.GET)
    public String printHello(HttpServletRequest request, Model model) {
...

存储库

@Repository
public class JpaRepositoryImpl implements JpaRepository {

    @PersistenceContext
    private EntityManager emf; // Для внедрения EntityManager
...

好吧，一堆其他必要的类

在 spring-db.xml 中连接的存储库

...
<context:component-scan base-package="ru.bityard.bitrix24.serverAuth.repository"/>
...

spring-mvc.xml 中连接的控制器和服务

...

    <context:component-scan base-package="ru.bityard.bitrix24.serverAuth.**.web"/>
    <context:component-scan base-package="ru.bityard.bitrix24.serverAuth.**.service"/>

    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/jsp/"/>
        <property name="suffix" value=".jsp"/>
    </bean>
...

我在 spring-app.xml 中收集所有其他 bean

这就是我试图在 web.xml 中组合的所有内容

在 IDEA 中执行 install jar 后，昵称会进入本地 maven 存储库 .m2/repository/

之后，我在 pom.xml 的新项目中向我的包添加依赖项：

        <dependency>
            <groupId>ru.bityard.asterisk</groupId>
            <artifactId>ami</artifactId>
            <version>1.0.0</version>
        </dependency>

IDEA 看到并加载它。

现在我正在尝试从这个包中创建一个类的实例，但它不起作用...... IDEA 本身要求将导入添加到包中？我同意，没有任何反应...

想法截图

我试图用我的双手书写路径

import ru.bityard.asterisk

但IDEA没有看到它......

我看到在maven加载的所有包中，classpath都是从包的根目录开始的，例如：

org/springframework/...

在我的包裹中，路径开始

BOOT-INF/classes/ru/...

也许这就是问题所在？帮助我理解。

在另一堂课我做反思

DeliveryOrder[] deliveryOrders = {do1,do4,do3,do2};

try {
    method = reCallReportController.getClass().getDeclaredMethod("getOrdersMap", DeliveryOrder[].class);
    method.setAccessible(true);
    deliveryOrderMap = (Map<String, Set<DeliveryOrder>>) method.invoke(reCallReportController,deliveryOrders);

如何提出请求并处理它们 - 我想通了。

以及如何配置应用程序以侦听特定端口，我想不通。

特别是，我需要从 Bitrix24 制作一个传入的 webhook 处理程序。那些。

Bitrix 手册说：

укажите url вашего обработчика в настройках исходящего webhook
https://your_server/your_webhook_script.php


код обработчика

<?php

/*

Битрикс24 передает в обработчик $_REQUEST с данными:

array(
 'PHONE_NUMBER' => '555666777', //номер, на который звонит пользователь Битрикс24
 'USER_ID' => '1', //пользователь, который звонит из интерфейса Битрикс24
 'CRM_ENTITY_TYPE' => 'LEAD', //тип объекта CRM, из карточки которого звонит пользователь Битрикс24

为什么objectMapper它看不到对象的字段设置器Pojo？

班级User

    public class User {
        private String ID;
        private boolean ACTIVE;
        private String UF_PHONE_INNER;

        public String getID() {
            return ID;
        }

        public void setID(String ID) {
            this.ID = ID;
        }
... и т.д.

班级Users

public class Users {
    private User[] result;

    public User[] getUsers() {
        return result;
    }

    public void setResult(User[] result) {
        this.result = result;
    }
и т.д....

拆解JSON

log.debug("jsonString is {}",jsonString);
users.setResult(objectMapper.readValue(jsonString, Users.class).getUsers());

我得到：

DEBUG log:71 - jsonString is {"result":[{"ID":"1","ACTIVE":true,...
WARN  log:81 - com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException: Unrecognized field "ID" (class ru.bityard.bitrix24.User), not marked as ignorable (3 known properties: "id", "active", "uf_PHONE_INNER"])

我不明白为什么他看到id而不是ID？？？我的印象是解析器将字段ID视为对象......

大家好！

我在 spring-app.xml 中设置了日志 bean：

<bean id="logger" scope="prototype" class="org.slf4j.LoggerFactory" factory-method="getLogger">
        <constructor-arg name="name" value="log"/>
</bean>

此外，我在类中放置了各种情况所需的日志记录级别：

@Autowired
private Logger log;

log.warn(...);
log.info(...);
log.debug(...);

我有一个在启动时加载到程序中的 config.conf 文本文件：

Properties properties = new Properties();
properties.load(this.getClass().getClassLoader().getResourceAsStream(configFile));

如何设置日志记录级别（信息、调试），比如控制台，我可以在 config.conf 文件中指定？

一旦我释放 jar 并尝试在 Idea 之外运行它，就会出现错误：

Exception in thread "main" org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Unable to locate Spring NamespaceHandler for XML schema namespace [http://www.springframework.org/schema/context]

这是开始类：package ru.start;

import org.springframework.context.ApplicationContext;

import org.springframework.context.support.ClassPathXmlApplicationContext;

@Configuration

我的任务是在页面更新时将数据保存在页面上。

那些。我在 JSP 中有呈现复选框的代码。我不知道他们的名字和号码。

<c:forEach items="${trunks}" var="trunk">
 <jsp:useBean id="trunk" scope="page" type="ru.bityard.pojo.Trunk"/>
  <tr>
   <td style="padding: 5px; vertical-align: middle">
    <input type="checkbox" 
           name="${trunk.name}" 
           value="${trunk.name}" 
           <%= ("on".equals(checkbox) ? "checked" : "") %>
    />
    ${trunk.name}
   </td>
  </tr>
</c:forEach>

有一个控制器接受 PostMapping ，做它需要的事情，包括将所有参数传递给 GetMapping。

@PostMapping
 public String call(HttpServletRequest request, Model model) {
  ...
        // Вытаскиваю все параметры, со всеми значениями
        Map<String, String[]> parameters = request.getParameterMap();

        // Записываю все параметры в модель и передаю на GetMapping
        model.addAllAttributes(parameters);

        return "redirect:/missedCalls";
    }

@GetMapping
    public String create(HttpServletRequest request, Model model) {
        ...
        model.addAllAttributes(request.getParameterMap());
        return "missedCalls";
    }

在这里我不知道如何检查变量是否具有“on”值，然后我们放置“checked”标志。由于我的变量名是动态设置的=${trunk.name}

我不知道如何将(checkbox)变量名传递给这个表达式而不是存根：

<%= ("on".equals(checkbox) ? "checked" : "") %>

我有一个带有 required=true 选项的输入字段和一个提交按钮。我希望输入字段在单击提交时将所需选项设置为 false。

<table style="width: 100%">
 <tr>
  <td>
   <input class="form-control col-5" name="agent" id="agent" value="${agent}" placeholder="<spring:message code="report.missedCalls.agent"/>" required="true">
  </td>
  <td align="right">
   <button id="refresh" type="submit" class="btn btn-lg small btn-primary" onclick=checkform()>
    <spring:message code="report.refresh"/>
   </button>
  </td>
 </tr>
</table>

<script>
    function checkform()
    {
        $("#agent").required=false;
    }
</script>

但有些东西对我不起作用，需要禁用。

请帮帮我

一个东西：

public class MissedCall {

    private Timestamp dateTime;
    private String callerId;    
    private Long duration;       

    public MissedCall(Timestamp dateTime, String callerId, long duration) {
        this.dateTime = dateTime
        this.callerId = callerId;
        this.duration = duration;
    }

执行请求的方法：

public class JdbcMissedCallRepositoryImpl implements JdbcMissedCallRepository {
    ...

    private static final RowMapper<MissedCall> ROW_MAPPER = BeanPropertyRowMapper.newInstance(MissedCall.class);
    ...
    public List<MissedCall> getForLastDays() {
    ...
    List<MissedCall> missedCalls = jdbcTemplate.query(query, ROW_MAPPER);
    ...
    }

结果，在列表中我得到一个空的 MissedCall 对象......

如果查询是手动执行的，那么结果是：

+---------------------+-------------+------+
| atm                 | asrc        | adur |
+---------------------+-------------+------+
| 2018-05-02 19:46:21 | 89181112233 |    4 |
+---------------------+-------------+------+
1 row in set (0.00 sec)

他需要什么来匹配这些字段？

怎么做：“纯文本 -链接”

我愿意：

Hyperlink hyperlink = new Hyperlink("Ссылка");    
Label label = new Label("Простой текст - ");
Pane pane = new Pane();
pane.getChildren().addAll(label,hyperlink);
bottomBorderPane.setCenter(pane);

但是最后超链接和标签是在一个上面显示的，而不是在bottomBorderPane的中心，而是在左边...
