我正在从事一个现有的springboot2.4项目，并试图将webflux和r2dbc引入一个现有的基于jpa的应用程序中。
我可以引入webflux依赖项：

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

没有任何问题，我的应用程序启动和行为，因为它应该，能够执行一些测试使用通量/单声道和一切都很好。
然而，为了获得完全的React性，我需要一直到持久层，也就是说，引入r2dbc依赖（对于postgres）

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-r2dbc</artifactId>
</dependency>
<dependency>
<groupId>io.r2dbc</groupId>
    <artifactId>r2dbc-postgresql</artifactId>
    <version>0.8.6.RELEASE</version>
</dependency>

我有以下配置类：

@Configuration
@EnableR2dbcRepositories(
        repositoryBaseClass = ReactiveCrudRepository.class
)
public class R2DBCConfiguration extends AbstractR2dbcConfiguration {

    @Bean
    @Qualifier("rxConnectionFactory")
    @Override
    public ConnectionFactory connectionFactory() {
        return new PostgresqlConnectionFactory(
                PostgresqlConnectionConfiguration
                .builder()
                .username("user")
                .password("password")
                .host("localhost")
                .port(5432)
                .database("my_db")
                .build()
        );
    }
}

由于这种依赖关系，我的项目无法启动，始终会出现相同的异常：

我不明白为什么会发生这种情况-我们的dao使用传统的simplejparepository实现/没有一个扩展了reactivecrudepository，因此从应用程序的Angular 来看不应该被“视为”React存储。
在任何情况下，我想知道是否其他人也遇到过类似的情况和可能的解决方法/修复方法。
