Developing Java Applications with Spring and Spring Boot

Removing the PostgreSQL and Spring Data JPA dependencies

We will convert our project to use the brand new Spring Data Reactive MongoDB repositories. After that, we will not use the Spring Data JPA and PostgreSQL drivers anymore. Let's remove these dependencies from our pom.xml:

<dependency>  <groupId>org.springframework.boot</groupId>  <artifactId>spring-boot-starter-data-jpa</artifactId></dependency><dependency>  <groupId>org.postgresql</groupId>  <artifactId>postgresql</artifactId>  <version>42.1.4</version></dependency>

And then, we can add the following dependency:

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

The final version of pom.xml can be found ...
