Spring R2dbc Example

This repository contains the latest changes in the Spring R2dbc(part of Spring Framework 5.3), Spring Data R2dbc 1.2 and Spring Boot 2.4.

I have created several R2dbc examples in the spring-reactive-sample repository since it was born. But Spring Data R2dbc evolved very quickly, thre are plenty of breaking changes introduced since Spring 5.2 and Spring Data R2dbc 1.2.

Compare to the Spring Data R2dbc 1.1, some breaking changes are notable.

  • The old DatabaseClient in Spring Data R2dbc 1.1 was split into two parts, a simple new DatabaseClient is part of Spring framework, as an alternative of Jdbc.
  • Another part of the old DatabaseClient is reorganized into a new class R2dbcEntityTemplate which acts as the role of JdbcTemplate.
