Across 5.2.2 Release notes

By Davy

November 7, 2023

Small maintenance upgrade to make it possible to use Spring Boot 2.6 with Across 5.2, without completely rebuilding Across Framework and Platform.

Bug fixes

Fixed an NPE which happens with Spring Boot 2.6.

Using 5.2.2 with Spring Boot 2.5 or 2.6

The Across 5.2.x series is based on Spring Boot 2.4. With some work on your side, you can already upgrade to Spring Boot 2.6 (but probably not to 2.7: that will require more work in Across itself). Note that Across 5.4 will be based on Spring Boot 2.6.

To make this possible, there is a new across-platform-bom maven module to Across Platform. This is intended to put the application in control of its our build, rather than Across.

Note this has disadvantages too: the tradeoff is: you are in control, but you will have more work. It’s analogous to the tradeoff between inheriting from spring-boot-starter-parent vs importing spring-boot-dependencies, which is discussed succinctly here:

https://www.baeldung.com/spring-boot-dependency-management-custom-parent

To use this feature and switch to Spring Boot 2.6, replace this in your top-level pom.xml file:

<parent>
	<groupId>com.foreach.across</groupId>
	<artifactId>across-application-parent</artifactId>
	<version>5.2.1.RELEASE</version>
</parent>

with:

<parent>
	<groupId>org.springframework.boot</groupId>
	<artifactId>spring-boot-starter-parent</artifactId>
	<version>2.6.15</version>
</parent>

and add this in the <dependencyManagement> section:

<dependencyManagement>
	<dependencies>
		<dependency>
			<groupId>com.foreach.across</groupId>
			<artifactId>across-platform-bom</artifactId>
			<version>5.2.2.RELEASE</version>
			<type>pom</type>
			<scope>import</scope>
		</dependency>
	</dependencies>
</dependencyManagement>

Essentially, this switches your application from using Across as your “platform” (from a Maven perspective at least!) to:

Spring Boot as your “platform”.
and Across Framework and the Platform modules as “just another set of libraries”.

Compare this for instance with using the JUnit BOM. You’ll see it’s quite similar.

Unless your team knows Maven well, I do not advise you to do this. In fact, probably the only sensible time to use this, is if your application is migrating away from Across.

Upgrades

Upgraded ax-bootstrap-theme-module and ax-bootstrap-4-utilities from 0.0.1.RC1 to 0.0.1.RELEASE.
