Using a reactive driver like R2DBC together with Spring WebFlux allows you to write a full application that handles receiving and sending of data asynchronously. It allows data to be streamed asynchronously to any endpoints that have subscribed to it. Not too long ago, a reactive variant of the JDBC driver was released, known as R2DBC. I will keep this post short by providing brief notes alongside the implementation for MSSQL. That being said, below is its introduction which should provide enough context for us to continue. As Spring provides a lot of magic, most of the code from my previous Postgres post will still work and only requires a few changes to get up and running with MSSQL.įor more background information, I do recommend reading the Postgres version of this post as I do not want to repeat myself too much. So, you should know that I will be writing about Spring Data R2DBC’s integration with Microsoft SQL Server. Hopefully, you read the title before traversing to this page. We can easily accomplish this by just testing the repository layer.This post is the sibling of another blog post I wrote that focused on Spring Data R2DBC and Postgres. In any of these tools, it's straightforward to create a database table either by executing an SQL script in the Database Manager or within the IDE.įinally, we should make sure that Spring Boot can actually connect to HSQLDB. On Linux/Unix/Mac, we can use NetBeans, Eclipse, or IntelliJ IDEA to create the database connection through the IDE's visual tools, using the same credentials.

URL: jdbc:hsqldb:hsql://localhost/testdb.

This will open HSQLDB Database Manager's initial screen, where we can enter the connection credentials: To do this on Windows, let's go to the database bin folder and run the runManagerSwing.bat file. Once the database has been set up, we need to create a connection to it.

We can make sure the database has been actually created by going to the data folder, which should contain a set of files called “testdb.lck”, “testdb.log”, “testdb.properties”, and “testdb.script” (the number of files varies depending on the type of database we're creating).

The above command will start the HSQLDB server and create our database whose source files will be stored in the data folder.

lib/hsqldb.jar -database.0 file.testdb -dbname0.testdb

Within the data folder, we'll run the following command:.We'll launch a command prompt and navigate to the HSQLDB data folder.

Since HSQLDB doesn't provide a default database out of the box, we'll create one called “testdb” for example purposes.First, we'll download HSQLDB and unzip it to a folder.Here are the steps that we should follow:
