I searched spring on maven, and I find it at this page :http://mvnrepository.com/artifact/org.springframework/spring. The problem is I want to download 4.0 version but there is no 4.0 version in the chart.
Newer version of Spring can be found under group id org.springframework - Spring 4+
There is no reason to include all features of Spring Framework in one .jar. Spring is huge and you will probably won't use every feature of Spring. Including everything will cause unnecessary overhead. Pick what components you need add them to pom.xml and Maven will download them. If you found out later you need additional dependency just add it on the fly...
As an alternative you can use Spring Boot which will generate project for you with default set up. You can generate such a project using Spring Initializr Spring Boot Initializr. At the bottom click Switch to the full version. Pick what you need and hit generate project.

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 {})
Spring boot starter project provides extensive set of functionalities auto configured. But for our application we want to have only a subset of functionality. May be only one feature out of the spring boot starter project. So is it advised to have custom starter project on top of spring boot provided starter project to mask some of the features or write new starter project directly from lower level libraries?
Spring boot starter project provides extensive set of functionalities
auto configured
There are two separate concerns you are talking about.
I think the auto configured part is something which is Spring boot's opinionated way of configuring. As an example if in classpath it finds a in-memory database library ( like H2) it automatically creates a datasource (pointing to embedded in-memory database) which is available for autowiring without you writing the configuration in a Java config class. Of course you can create you own datasource of choice by including appropriate driver jar for that database. Similarly lots of other configurations are done by default by classpath scanning and availability of certain jars and classes.
The second part - is more of a dependency issue in general. Say you want to use web mvc part in Spring boot. This will require a consistent set of dependencies and transitive dependencies as well. Rather than finding and declaring the dependency in your build tool of choice ( maven, gradle etc) it has created the concept of starter projects where you simply mention the parent and all the right dependencies would be pulled on. This gives a great way to correctly lock your dependencies. However if you want to include any different version than what is provided by boot starter ( provided there is no compatibility issues with those different versions) you can still add explicitly in your build tool. For e.g., maven will by default include the highest version of a particular dependency among all available via transitive dependencies when it resolves dependency for an artifact.
I want to use "feign" dependency in my spring boot project, Is there any source like https://mvnrepository.com/ to get dependency?
You can use spring initializer. https://start.spring.io/. I would suggest you to always use one version lower than the latest version of snapshot. Cause newer version might not be that standard.
You may use spring initializer i.e https://start.spring.io/. Go to the site and fill in all the details.Select the dependency you want(in your case feign). Select generate. It will generate a zip file with your starter project. Import it and you can start coding.You can see a picture demonstrating the same in this link The spring initializer
Alternatively you can do the same using Spring tool suite. You can download STS here Spring Tool Suite.
->Install and open spring tool suite.
->Click File>>New and select spring starter project. If u don't get the option there, choose other and then search for spring starter project.
->After choosing spring starter project, fill in all the necessary details and click next.
->In the next section choose all the dependencies you require(in your case feign).
->click finish and you are good to go.
Happy Coding.
I found that,we can search search same in https://mvnrepository.com/ with spring suffix
Ex: feign spring
i created a maven project, and added all dependencies i need.
i have some repositories using the spring-data-jpa, and i added some integration tests.
now i need to add ontop of it spring-data-rest, if i understand it is based on springmvc.
but all examples i found, i need to add spring boot to start the app.
i noticed also all new spring projects use spring boot.
this means that i have to learn and use it for my projects?
how can i use spring-data-jpa+spring-data-jpa with an existing servlet3 project
The reason all examples are written using Boot is that Boot is indeed the way you should start a new Spring project these days. It free's from a lot of the tedious work of setting up the infrastructure, finding dependencies in the right version etc.
To use Spring Data REST without Boot, simply add the necessary dependencies to your project. The easiest way to do this is to use the Spring Data Release Train BOM (which will help you pulling in the correct matching versions) along side the version-less dependency declarations for Spring Data REST WebMVC and - in your case - Spring Data JPA.
Then go ahead and either register RepositoryRestMvcConvfiguration as Spring bean (either through XML configuration or JavaConfig).
All of this is also documented in the reference documentation.
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.
