Customizing Spring Boot dependency versions - maven

I am looking for a way to customize Spring Boot transitive dependency versions.
Say I want to use a different version of Spring Framework.
Is this possible? If so how - bearing in mind I use Maven.

You can by specifying the spring.version property, assuming that you use the spring-boot-starter as a parent.
<properties>
<spring.version>your-version-here</spring.version>
</properties>
If it is wise is an entirely different question (there is code in Spring Boot that assumes certain things to be available and to make sure that it works you would at least have to use Spring version 4.0.3 I guess.

Selenium 4.1 and Spring boot Web driver version issue

I tried to migrate gradle project with spring boot from selenium 3 to selenium 4
(implementation 'org.seleniumhq.selenium:selenium-java:4.1.1')
But chrome, firefox and edge web drivers remains from selenium version 3
(org.seleniumhq.selenium:selenium-chrome-driver:3.141.59).
If I remove spring boot dependency from project, they updates to 4.1.1
Currently using gradle version "7.3.3".
Spring boot "2.6.3".
Spring dependency management "1.0.11.RELEASE".
Any ideas why this happens, I hoped that dependency hell dissapeared with spring boot creation)
Thanks in advance!
I have the same promble, I found in spring-boot-starter-parent, there is a spring-boot-dependencies in ~/.m2/repository/org/springframework/boot/spring-boot-dependencies/2.6.3/spring-boot-dependencies-2.6.3.pom, which declared <selenium.version>3.141.59</selenium.version> in properties, so you can try add
<properties>
<selenium.version>4.1.2</selenium.version>
</properties>
in your project pom.xml.
Spring Boot comes with a set of versions that are know to work together. But you can override them in your build script. In case of Gradle, add to build.gradle:
ext['selenium.version'] = '4.1.2'
It is because Spring Boot comes packed with a set of predefined dependecies that you can find here: https://docs.spring.io/spring-boot/docs/2.6.7/reference/htmlsingle/#appendix.dependency-versions
In this page, you will also find, how to change predefined version. In general, you need to add .version to your dependency name and, in case of multiple word names, you change spaces to dashes (not needed in case of selenium).
So, to change version to most recent, type in build.gradle ext['selenium.version'] = '4.4.0' at 0 indent level. (don't add it, say inside dependencies {})

Which dependency should be used to integrate Apache Camel with Spring Boot

Apache Camel provides two ways to integrate with Spring Boot:
camel-spring-boot
camel-spring-boot-starter
When I look at the starter then I see that it only includes camel-spring-boot and spring-boot-starter. What is the difference then and what are the advantages of using starter?
At the moment of writing this answer, camel-spring-boot is only supported from Camel 2.15 and camel-spring-boot-starter only from Camel 2.17, which is important considering the current version that your project is using.
Then the major difference between these two dependencies, lies in the "opinionated" auto-configuration provided by the starter.
camel-spring-boot, should be used if you want just to include a jar to make your camel routes auto-discovered by spring boot, this also gives you the freedom to update this dependency regardless of your spring-boot version.
camel-spring-boot-starter, (recommended way to go) should be used if you want a collection of dependencies (including camel-spring-boot) that provides the best developer/user experience, due to the fact of customizable properties, additional libraries, and default configuration for the camel library. Check the reference documentation for the starter: https://camel.apache.org/components/latest/spring-boot.html#_spring_boot_auto_configuration
Summary
Use camel-spring-boot, if you want a vanilla jar to use camel with spring boot
Use camel-spring-boot-starter, if you want an automatic-configured component to start to develop with.
You should always use the camel-xxx-starter dependencies, as these are the Camel components that is support with Spring Boot. Also as mentioned they provide auto configuration and some of them additional capabilities.
If there is no camel-xxx-starter component then its because its not supported on Spring Boot with Camel.

spring integration data-redis and data-jpa version compare my project data-redis and data-jpa version

In a project developed with Spring boot 1.5.7, data-redis and data-jpa was used. Data-jpa version is 1.11.7, data-redis version is 1.8.7. I need to add spring-integration to the project. I will use version 4.3.12. data-jpa version in this version is 1.10.10, data-redis version is 1.7.10.
It is not the same as the data-redis and data-jpa versions used in the project.
What problems can this cause ?
That can't cause any problem as far as you don't override any dependencies provided by Spring Boot. You really should just rely on the well-tested composition of dependencies represented in Spring Boot. Even if Spring Integration 4.3.12 brings Spring Data JPA 1.10.10 as a transitive dependency that doesn't mean that it is not overridden by Spring Boot.
I'm not sure which do to point you out, but one of the main goals in Spring Boot is to bring into the target project consistency and cross-compatibility in the dependencies part.
This might help you a bit: https://docs.spring.io/spring-boot/docs/2.0.3.RELEASE/reference/htmlsingle/#using-boot-dependency-management

Spring Boot and Spring Data Jpa versions compatiblity

I am using the latest (by the time of writing) Spring-Boot-starter-data-jpa (version 1.2.6.RELEASE). I find it actually uses the Spring-data-jpa version 1.7.3.RELEASE, which is considerably behind the latest (1.9).
Is it a supported approach to upgrade individual dependencies such as the Spring-data-jpa? If I do this myself, for example, by declaring a direct dependency on the wanted newer version (may just override the version properties), any side effect you guys foresee?
The reason why I am doing this is that I need to use a special parameter in this annotation:#EnableJpaRepositories(repositoryBaseClass = JpaRepositoryWithI18n.class)
That is not available in the supplied 1.7.3 jpa library.
Any workaround would be appreciated too.
Thanks
EDIT:
I tested the following two ways: 1) declared a direct dependency to Spring-JPA-data 1.9.0 and excluded it from spring-boot-starter-data-jpa 2) upgrade Spring-boot-web-starter to 1.3.0m5
2) worked out well for me. This is also what dunni's answer suggested.
I have not tested Andi's answer as this is a new project, we could easily upgrade the entire spring boot and regression test it without worrying too much about side-effects.
But I can see Andi's answer is an easier approach than 1). More importantly, it shows how you can upgrade other dependencies independently -- just overide the versions in parent pom.
Thanks
Spring Data JPA 1.9 is part of the Spring Data Gosling release train. As described in the Gosling announcement you can use it with Spring Boot 1.2:
To upgrade to the new release train use the BOM we ship as described in our examples repository and configure its version to Gosling-RELEASE. If you’re using Spring Boot, upgrading to the release train is as easy as setting the Maven property spring-data-releasetrain.version to that version. Note, that to use Spring Data REST with Boot 1.2, you also need to upgrade to Spring HATEOAS 0.19.0.RELEASE (by setting the spring-hateoas.version property) and Jackson 2.5 or better (current 2.6.1 preferred, via the jackson.version property).
In short, add this to your pom:
<properties>
<spring-data-releasetrain.version>Gosling-RELEASE</spring-data-releasetrain.version>
</properties>
It's not supported in that matter, that the Spring Boot test cases don't include newer versions. So your application might work with the newer version, but there may be some errors. With minor releases it's more likely to work without problems than with major version upgrades. You can also upgrade Spring Boot to 1.3.0.M5 (you should note however, that this is a milestone version, not yet the release).

struts 2 spring plugin - spring version

When using the spring plugin for struts 2, is it possible to use the latest version of spring or are you stuck with the version referenced in the plugin? For example in my project I am using struts 2.3.16.3 and its spring plugin automatically uses spring 3.0.5 . So if I add spring 4.1 to my pom as a dependency then there are multiple versions of spring added to the classpath.
You shouldn't have more than one Spring library in your classpath - disaster will be bound to happen. I guess you can either exclude the spring dependency in that plugin or set its version to the one you want.
The main problem with this approach is moving between major versions (3.x to 4.x) - if Spring is respecting Semantic Versioning incompatibilities will exist between the two versions and it is possible (or likely) that struts2-spring-plugin is using something that changed.
Edit: Comment below reports successful usage of struts2-spring-plugin and Spring4.
