Answer 1

The version of spring-data-r2dbc that you are using isn't compatible with the versions of the other Spring Data modules that Spring Boot 2.3.x uses by default.

Spring Boot 2.3 has dependency management and a starter module for Spring Data R2DBC so you can align the versions by using the starter and removing the versions from your pom.

Replace the following three dependencies:

<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-r2dbc</artifactId>
    <version>1.0.0.RELEASE</version>
</dependency>
<dependency>
    <groupId>io.r2dbc</groupId>
    <artifactId>r2dbc-spi</artifactId>
    <version>0.8.0.RELEASE</version>
</dependency>
<dependency>
    <groupId>io.r2dbc</groupId>
    <artifactId>r2dbc-postgresql</artifactId>
    <version>0.8.0.RELEASE</version>
</dependency>

With the following:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-r2dbc</artifactId>
</dependency>
<dependency>
    <groupId>io.r2dbc</groupId>
    <artifactId>r2dbc-postgresql</artifactId>
    <scope>runtime</scope>
</dependency>

The spring-data-r2dbc and r2dbc-spi dependencies are both part of the spring-boot-starter-data-r2dbc dependency that replaces them. The versions are provided by the dependency management in spring-boot-starter-parent.

If you have a similar problem in the future using the Explore feature of https://start.spring.io can be useful for figuring out how your pom should look.
