小编use*_*282的帖子

当我启动我的应用程序时,我收到错误JPA: Reactive Repositories are not supported by JPA. 我的Pom具有以下依赖关系,我正在使用Spring Boot 2.0.5

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-webflux</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-jpa</artifactId>
        </dependency>

        <dependency>
            <groupId>com.h2database</groupId>
            <artifactId>h2</artifactId>
            <scope>runtime</scope>
        </dependency>

这是我的存储库界面.

public interface CustomerRepository extends ReactiveCrudRepository {
}

当我启动我的应用程序时,它会抛出错误:

org.springframework.dao.InvalidDataAccessApiUsageException: Reactive Repositories are not supported by JPA. Offending repository is com.example.demo.CustomerRepository!

下面是我的程序，当我输入相关的月份、日期和年份时，它返回错误的日期名称。

我在这里缺少什么？

我的程序

import java.util.Calendar;
import java.util.Locale;
import java.util.Scanner;

public class TimeTest {

    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        String month = in.next();
        String day = in.next();
        String year = in.next();

        System.out.println(getDay(day, month, year));
    }

    private static String getDay(String day, String month, String year) {
        Calendar calendar = Calendar.getInstance();
        calendar.set(Integer.parseInt(year), Integer.parseInt(month), Integer.parseInt(day));
        return calendar.getDisplayName(Calendar.DAY_OF_WEEK, Calendar.LONG, Locale.getDefault());

    }
}      

输出：

09
24
2018
Wednesday       

它应该返回“星期一”，因为那是当天。

有人可以告诉我们这里的情况吗..

我们的应用程序已经在使用 android native 内置的 Play 商店中，但是现在我们已经使用 react native 创建了新的应用程序，我们想在没有影响现有用户的情况下通过 react native 替换商店中的相同应用程序？

1. android 是否允许通过反应应用程序替换相同的本机应用程序我的意思是我们可以简单地将新版本推送到商店吗？

2. 如果允许会影响我们现有的用户我的意思是他们何时升级应用程序，这是否是一个简单的升级？
