I see there are three product lines on spring cloud. I am a newer of spring cloud and want to add to my project, which product line should I use?
Take a look at the versions of dependencies towards the bottom of the Spring Cloud project page.
You'll want to use the most current version for the most part since they are all marked GA, but also make sure they are compatible with whatever else you are using in your project.
So for example if you are using Spring Boot 1.2 then go with Angel, 1.3 then Brixton, 1.4+ then Camden is probably your best bet. Even then you can always get things working by resolving dependency conflicts yourself.
If its a brand new project, just go with Camden and call it a day.

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 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 have a spring 3 app deployed in openshift jboss eap6, and I want to upgrade to ver 4. I also want to upgrade to Java8. Has anyone here been successful in doing so? What are the things that must be considered? How can I make the transition easier? I'm so afraid of Jar hell.
Upgrading von Spring 3.0 to 4.0 could need some changes (depending on what you have done and used). I recommend to do it in small steps, so you can check that everything still works more often, so: uprade to 3.1 first, then 3.2, and then 4.0. After that upgrade to Java 8.
The Spring Reference contain some hints in the what is new section and this Wiki: Migrating from earlier versions of the Spring Framework
Attention: if you upgrade Spring Security too, then I strongly recommend to read its upgrade hints in its Migration documentation!
Solution to your Question
Don't worry Spring 4 is 100% compatible with Java 8
For Jars you need to use the Bill of Materials of Spring 4 Jars which can be obtained in this Link. Use only these jars which will take care of your dependencies issues.
Typically replace all these JAR files in your WEB Applications and try to build and deploy your application. You got your JAR upgrade if it runs without any issues. Most probably 100% it will run without any issues.
Then Depending your scenarios you can apply your spring-framework components.
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).
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.
