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

For years, I've used Spring Initializr (at https://start.spring.io/) to create the initial SpringBoot application and then modify it to create the app. This works fine.
Is there a maven archetype I can use to create a SpringBoot app? Or is the Spring Initializr the only way to do this.
Searching I found this:
What archetype to choose for a simple java project
Which shows the command:
mvn archetype:generate -Dfilter=org.apache.maven.archetypes:
Which gives me a list of 14 items to choose from. None of them mention SpringBoot.
The closest match is org.apache.maven.archetypes:maven-archetype-webapp, so I tried it and it created a WebApp (*.war) which is not what I'm looking for.
The aim of the Maven archetype is for generating a project skeleton. The Spring Initialiser also does the same but I think you should find it more user friendly to use when compared to executing a maven archetype command.
If you insist to use maven archetype , you can simply search Github to see if there are people share their archetypes (search result at here)
If your aim is just to use command to generate a spring-boot project skeleton , Spring Initializr actually provide an HTTP API to do it.
Also you can checkout JHipster, which is another tool to generate a spring-boot project skeleton.
You could also use Spring Boot CLI to scaffold new Spring Boot projects:
spring init --dependencies=web,data-jpa my-new-project
It works just as Spring Initializr, but on the command line.
See section 2.4 "Initialize a New Project" on Spring Boot CLI documentation here: https://docs.spring.io/spring-boot/docs/current/reference/html/cli.html#cli.using-the-cli.initialize-new-project
I have started learning about spring and in every tutorial they start from spring initializr, i was wondering is it necessary to use it or we can create a project without using spring initializr ?
No, it is no necessary. You can do everything by your own hands. It just helps you to start quicker so that you focus more on the Spring concepts instead of spending much time on "infrastructure" like configuring dependencies. You run it and it just works. Then you can extend it step by step. This can be especially helpful if you just start learning Spring. Later on you should of course spend some time on other aspects that initializr provides you.
Adding to whatever is already mentioned.
No , it is not necessary to create a project with Spring Initializr
The site provides a curated list of dependencies that you can add to
your application based on the selected Spring Boot version. You can
also choose the language, build system and JVM version for the
project.

Using Spring Initializr the right dependencies are preconfigured for the Spring Boot version used. These preconfigured projects reduces the setup time and one can start implementing the code rather than investing time on which dependencies to go with.
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 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.
I am trying to write the spring security hello world example, I am searching for the spring security jars to download manually, I had look here Seems there is no way to download them manually. It shows the way to add dependency though Maven.
Please suggest official link from where I can download the spring-security jars.
This shows all the projects in spring
SPRING FRAMEWORK 3.1.2
You can find spring security Jars here http://repo.spring.io/release/org/springframework/security/spring-security for all version
If you want other components of spring i.e jar you can browse through the same link by removing /security/spring-security enter in browser bar and search for other respective index you want by version.
The repository at http://repo.spring.io is browseable and searchable. But really you should be using an automated dependency manager. What's the problem?
