阶乘算法与分而治之范式有关吗？

5

在研究范式"Разделяй и властвуй"时，遇到了一个用有效的双重递归计算斐波那契数的例子。这里一切都很清楚，第一步的任务被分成 2 个具有双重递归的子任务，有一个基本情况，实际上，这是一个范例"Разделяй и властвуй"。

这里出现了问题：

数字阶乘的简单递归计算问题是否属于同一范式"Разделяй и властвуй"？

def recur_factorial(n):
   if n == 1:
       return n
   else:
       return n*recur_factorial(n-1)

我认为不是，因为在这里我没有看到将任务划分为几个较小的子任务，尽管我清楚地看到基本情况和递归的存在。我想验证我的推理。

在 Spring Security 中禁用匿名时，所有 url 都会自动发出 403

0

有一个使用Spring Security的Spring Boot项目。

授权过程通过会话，成功授权后，应用程序保存cookie信息。
对于/login并且/logout我将 url 访问设置为permitAll，并将 url 的其余部分绘制为已验证。

当用户在未经授权的情况下敲击安全 url 时，它表示anonymousUser正在运行。
调试时，很明显，如果Spring Security没有收到来自授权用户的请求，那么它会自动替换为anonymousUser。

作为Spring Security Configuration中的一个解决方案，我关闭了http.build匿名访问 ( anonymous.disable())，但是这样我的所有 url，包括那些，/login都/logout属于403 Forbidden.

怎么回事？如何解决问题？

如何将主 Spring Context 用于异步方法？

0

堆栈上有一个应用程序Spring Boot。应用程序有一个异步方法，它应该在后台与授权用户执行操作，但由于异步方法使用不同的上下文，它看不到授权用户。如何将主上下文传递给异步线程？

异步是通过@EnableAsync和@Async 实现的。

SpringAsync 配置：

@Configuration
@EnableAsync
public class SpringAsyncConfig {

    @Bean(name = "asyncExecutor")
    public Executor asyncExecutor() {
        ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
        executor.setCorePoolSize(3);
        executor.setMaxPoolSize(3);
        executor.setQueueCapacity(100);
        executor.setThreadNamePrefix("AsyncThread-");
        executor.initialize();
        return executor;
    }
}

HazelCast FencedLock 并不总是成功阻止其他节点的方法

1

决定синхронизировать了 2 个应用程序节点之间的方法。为此，我FencedLock从 library 中获取了解决方案HazelCast。我根据文档做了所有事情，节点互相看到并合并到кластер. 该方法也синхронизировался开始工作 1 次，但有时会重复该方法的工作（不经常）。

我无法理解它与什么有关！我通过创建一个分布式对象解决了这个问题IMap，我将它放在方法中，并基于它开始制定方法或忽略它。我认为它更像是一个拐杖。

有没有办法通过fencedLock-i 及其配置来解决这个问题？

PS 请不要链接到任何关键字并将我发送到google，因为文档很少，也没有工作代码示例。我将不胜感激。

hazelCast.yaml 文件：

hazelcast:
  network:
    join:
      multicast:
        enabled: true

HazelCastConfiguration 类：

@Configuration
public class HazelCastConfiguration {

    @Bean
    public com.hazelcast.config.Config hazelCastConfig() {
        return new Config();
    }

    @Bean
    public HazelcastInstance hazelcastInstance(Config hazelCastConfig) {
        return Hazelcast.newHazelcastInstance(hazelCastConfig);
    }

    @Bean
    public IMap<String, LocalDateTime> timeMap(@Qualifier("hazelcastInstance") HazelcastInstance hazelcastInstance) {
        return hazelcastInstance.getMap("hazelcastTimeMap");
    }

在方法上面，我挂断Spring Scheduler并设置它cron每 5 秒工作一次。

我添加IMap之前的方法：

@Scheduled(cron = "0/5 * * * * *")
    public void sentMessage() {
        FencedLock lock = hazelcastInstance.getCPSubsystem().getLock("myLock");
        if (lock.tryLock()) {
            try {
                System.out.println("test message!" + LocalDateTime.now());
            } finally {
                lock.unlock();
            }
        }
    }

他在 2 个节点之间工作的结果：

节点 1：

节点 2：

添加IMap并定位后，问题就消失了。

添加IMap后的方法：

@Scheduled(cron = "0/5 * * * * *")
    public void sentMessage() {
        FencedLock lock = hazelcastInstance.getCPSubsystem().getLock("myLock");
        if (lock.tryLock()) {
            try {
                LocalDateTime date = timeMap.get("message");
                if (date == null || LocalDateTime.now().isAfter(date)) {
                    System.out.println("test message!" + LocalDateTime.now());
                    timeMap.put("message", LocalDateTime.now().plusSeconds(4));
                }
            } finally {
                lock.unlock();
            }
        }
    }

无法在不同端口上运行 Spring Boot 应用程序

需要同时Spring Boot在 3 个不同的端口上运行应用程序。

我使用命令（使用不同的端口）：

java -Dserver.port=9091 -jar D:\IdeaProjects\Pet-projects\Coffeetearea\build\libs\Coffeetearea-0.0.1-SNAPSHOT.jar

java -Dserver.port=9092 -jar D:\IdeaProjects\Pet-projects\Coffeetearea\build\libs\Coffeetearea-0.0.1-SNAPSHOT.jar

java -Dserver.port=9093 -jar D:\IdeaProjects\Pet-projects\Coffeetearea\build\libs\Coffeetearea-0.0.1-SNAPSHOT.jar

它在控制台中给出错误：

Error: Could not find or load main class .port=9091

Error: Could not find or load main class .port=9092

Error: Could not find or load main class .port=9093

我无法弄清楚可能是什么问题。在所有来源中，该示例都遵循给定的命令。application.properties我加了，不加我也试了，server.port=9091结果是一样的。

更详细一点，然后我检查 operator 中的字符if，如果不等于这些字符，我将其添加到StringBuilder.

 for (Character ch : inputChars) {
     if (ch != '.' || ch != ',' || ch != '?') {
         stringBuilder.append(ch);
     }

想做这样的事情：

项目jar文件不包含依赖（没有开发环境不运行）

1

我正在整理一个旧的开源项目。我决定从装配Ant转移到Gradle. 我从中提取了一些库mvnCentral，一些是我编写并上传到的GitHub，通过JitPuck我将它们拉到项目中。问题是，当从jar文件运行时，通过linux-терминал，它显示一个错误：

Error: Unable to initialize main class org.opensourcephysics.cabrillo.tracker.Tracker
Caused by: java.lang.NoClassDefFoundError: org/opensourcephysics/display/OSPFrame

带有类的项目本身org/opensourcephysics/display/OSPFrame是通过依赖项拉起来的JitPack。看不懂是什么问题，因为是通过开发环境组装和启动的，没有问题。我自己解压了jar，里面只有Tracker项目（直接就是我的项目）的文件和类。

毕业典礼：

plugins {
    id 'java'
}

jar {
    manifest {
        // This is where the Main class is specified for launching applications (otherwise the jar will not start)
        attributes 'Main-Class': 'org.opensourcephysics.cabrillo.tracker.Tracker'
    }
}

group 'org.osptracker'
version '1.0-SNAPSHOT'

repositories {
    mavenCentral()
    // Added JitPack for working with dependencies via GitHub
    maven { url 'https://jitpack.io' }
}

dependencies {
    compile group: 'com.nativelibs4java', name: 'bridj', version: '0.7.0'

    implementation 'com.github.OpenSource-Physics-Tracker:AppleJavaExstensions:70fb48e5fe'
    implementation 'com.github.OpenSource-Physics-Tracker:OpenSourcePhysics:0770a07'
    implementation 'com.github.OpenSource-Physics-Tracker:FFMpeg:ef6949741c'

    compileOnly 'org.projectlombok:lombok:1.18.8'
    annotationProcessor 'org.projectlombok:lombok:1.18.8'
}

可以看到，开发环境通过依赖拉取这个库：

也就是说，项目本身并没有启动，因为 NoClassDefFoundError 抱怨库 class org.opensourcephysics，尽管这个库已成功添加到项目中。

我需要编写一种方法来识别输入的单词，而不管键盘语言如何。我主要使用俄语 (RU) 和英语 (US) 布局。我需要在使用英语键盘输入俄语单词时，系统知道我正在输入一个俄语单词，但没有切换到俄语键盘，反之亦然，这样它就可以识别输入的英语单词而不切换到英语键盘。例如，就像在 Google 搜索中所做的那样。如果你输入英文单词milk，它会返回milk。如果您以这种方式输入俄语单词milk - vjkjrj（英语-俄语键盘） - 它会给我带有俄语单词milk的结果。

例如：

牛奶
厄库树
阿卜杜勒·莱克夫
g.ht 果泥
i.go shupeaux

从哪里开始？也许有一些图书馆准备好了？

HashMap 具有相同的键！为什么？

0

我有一个循环填充HashMap. 它根据原则工作 - 对于每个部门负责人（例如：会计），都有一个以该部门员工列表形式存在的值。即：首长是关键，下属的名单就是名单。当我执行循环时，我怎么会得到几个相同的键。我阅读了 Map 存储唯一键或覆盖它们以代替现有键的所有资源。如何解决这个问题（也许有删除所有重复键的选项）？这甚至是怎么发生的？

PS 在类本身中，equals 和 hashCode 被重新定义。同样在 Gate、Depatrment 和 Room 类中。

员工：

public class Employee extends EmployeeGeneral {

    @Override
    public boolean equals(Object o) {
        if (this == o) return true;
        if (!(o instanceof Employee)) return false;
        Employee that = (Employee) o;
        return room.equals(that.room) && department.equals(that.department) && upDepartment.equals(that.upDepartment) && gate.equals(that.gate);
    }

    @Override
    public int hashCode() {
        return Objects.hash(room, department, upDepartment, gate);
    }

    private static final long serialVersionUID = 372342343809L;

    private Room room;

    private Department department;

    private Department upDepartment;

    private Gate gate;

    public static final Field ROOM;

方法：

for (MSEmployee m : employees) {

            MSEmployee manager = msEmployeeRepository
                    .findFirstByDocID(departmentManagerMap.get(m.getDepartment().getId()));

            if (manager == null) continue;

            List<MSEmployee> msEmployeeList = msEmployeeRepository
                    .findAllByIdInAndDepartmentDocIdIn(employeesIds, manager.getDepartmentDocId());

            employeesWithManagers.put(manager, msEmployeeList);
        }

我有一个Spring MVC要添加到的应用程序Docker。我成功地创建了映像并进行了配置Docker，但是当我运行它时，我得到了一个错误PostgresSQL。

org.postgresql.util.PSQLException: Connection to localhost:5432 refused. Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections.

为了解决这个问题，我尝试了不同的选项：

改名localhost为db：spring.datasource.url=jdbc:postgresql://db:5432/coffeetearea.
尝试使用不同的端口运行。
单独表示server.post = 5432。

没有一个选项起作用。可以做什么？

PS项目组装完成：Spring boot,,,HibernatePostgresSQL

码头文件：

FROM openjdk:11
ADD build/libs/Coffeetearea-0.0.1-SNAPSHOT.jar Coffeetearea-0.0.1-SNAPSHOT.jar
EXPOSE 5432:5432
ENTRYPOINT ["java", "-jar", "Coffeetearea-0.0.1-SNAPSHOT.jar"]

无法将图像加载到磁盘（Spring MVC）

0

我写了一个方法，好像是把传输的文件加载到桌面上的文件夹中，但是不起作用。

服务：

@Value("${upload.path}")
private String uploadPath;

public void uploadDrinkImage(MultipartFile multipartFile) throws IOException {
    String filePath = uploadPath;
    multipartFile.transferTo(new File(filePath));
}

控制器：

@RolesAllowed({ROLE_CUSTOMER})
@PostMapping("/image")
public void uploadImage(@RequestParam("imageFile") MultipartFile multipartFile) throws IOException {
    drinkService.uploadDrinkImage(multipartFile);
}

应用程序属性：

#Path
upload.path=C:/Users/vartanyan/Desktop/images/

如何显示数据库中最受欢迎的 6 种饮品？

0

有一张桌子CART_ITEMS，哪里drink_id是id饮料，order_id是id它所在的顺序，是顺序中count这种饮料的数量。您需要展示此表中最受欢迎的 6 种饮品。我不明白这是如何实现的......我得到它如下：

select drink_id from cart_items
    where drink_id=(select drink_id from cart_items group by drink_id order by count(6) desc limit 1)
group by drink_id
limit 6

因此，它不起作用。仅显示一种最受欢迎的饮料。

如何在数据库中存储产品的照片？

我正在MVC Rest api使用Spring Boot, Hibernate,编写在线商店PostgreSQL。我需要有货物的照片。因此，从这里的一个问题一般来说它是如何实现的？将图片直接存储在数据库中的选项将不起作用，因此我决定将指向我硬盘上的照片的链接存储在数据库中。但是如何在代码中实现这一切呢？事实证明，Entity我有一个 type 的字段String？

爪哇：

private String image;

SQL：

alter table drink add column image varchar;

并在带有照片链接（路径）的数据库列中？在这种情况下，如何在客户端显示图像，因为给我的不是照片，而是链接？原来你需要写一个方法，在输出之前通过引用找到文件并显示出来？但是怎么做？

Spring Boot MVC 中的分页 - 应用程序（不翻页）

有注册方法。那里传递了两个 String 类型的参数 password 和 password2。我需要比较它们是否相等。我试图通过 == 或 equals() 来完成，但它不起作用。我知道 equals 应该被覆盖，但在这种情况下我该怎么做呢？

        newUser.setRole(User.ROLE_CUSTOMER);

枚举角色：

package com.tinychiefdelights.model;


public enum Role {

    COOK, ADMIN, CUSTOMER


}

P.S. В проекте нет Front'а вообще. Все методы я пробую в ручную через Swagger и до этого у меня все отлично работало! В чем может быть проблема?

Пробовал и без hasRole. Пробовал просто через @RolesAllowed, не помогает.
