|

http://pivotal.io/platform-as-a-service/migrating-to-cloud-native-application-architectures-ebook[Cloud Native] is a style of application development that encourages easy adoption of best practices in the areas of continuous delivery and value-driven development.
|
||||
A related discipline is that of building http://12factor.net/[12-factor Applications], in which development practices are aligned with delivery and operations goals -- for instance, by using declarative programming and management and monitoring.
|
||||
Spring Cloud facilitates these styles of development in a number of specific ways.
|
||||
The starting point is a set of features to which all components in a distributed system need easy access.
|
||||
|
||||
Many of those features are covered by http://projects.spring.io/spring-boot[Spring Boot], on which Spring Cloud builds. Some more features are delivered by Spring Cloud as two libraries: Spring Cloud Context and Spring Cloud Commons.
|
||||
Spring Cloud Context provides utilities and special services for the `ApplicationContext` of a Spring Cloud application (bootstrap context, encryption, refresh scope, and environment endpoints). Spring Cloud Commons is a set of abstractions and common classes used in different Spring Cloud implementations (such as Spring Cloud Netflix and Spring Cloud Consul).
|
||||
|
||||
If you get an exception due to "Illegal key size" and you use Sun's JDK, you need to install the Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files.

||||

Extract the files into the JDK/jre/lib/security folder for whichever version of JRE/JDK x64/x86 you use.
|

|
||||
== Building
|
||||
|
||||
:jdkversion: 1.7
|
||||
|
||||
=== Basic Compile and Test
|
||||
|
||||
To build the source you will need to install JDK {jdkversion}.
|
||||
|
||||
Spring Cloud uses Maven for most build-related activities, and you
|
||||
should be able to get off the ground quite quickly by cloning the
|
||||
project you are interested in and typing
|
||||
|
||||
----
|
||||
$ ./mvnw install
|
||||
----
|
||||
|
||||
NOTE: You can also install Maven (>=3.3.3) yourself and run the `mvn` command
|
||||
in place of `./mvnw` in the examples below. If you do that you also
|
||||
might need to add `-P spring` if your local Maven settings do not
|
||||
contain repository declarations for spring pre-release artifacts.
|
||||
|
||||
NOTE: Be aware that you might need to increase the amount of memory
|
||||
available to Maven by setting a `MAVEN_OPTS` environment variable with
|
||||
a value like `-Xmx512m -XX:MaxPermSize=128m`. We try to cover this in
|
||||
the `.mvn` configuration, so if you find you have to do it to make a
|
||||
build succeed, please raise a ticket to get the settings added to
|
||||
source control.
|
||||
|
||||
For hints on how to build the project look in `.travis.yml` if there
|
||||
is one. There should be a "script" and maybe "install" command. Also
|
||||
look at the "services" section to see if any services need to be
|
||||
running locally (e.g. mongo or rabbit). Ignore the git-related bits
|
||||
that you might find in "before_install" since they're related to setting git
|
||||
credentials and you already have those.
|
||||
|
||||
The projects that require middleware generally include a
|
||||
`docker-compose.yml`, so consider using
|
||||
http://compose.docker.io/[Docker Compose] to run the middeware servers
|
||||
in Docker containers. See the README in the
|
||||
https://github.com/spring-cloud-samples/scripts[scripts demo
|
||||
repository] for specific instructions about the common cases of mongo,
|
||||
rabbit and redis.
|
||||
|
||||
NOTE: If all else fails, build with the command from `.travis.yml` (usually
|
||||
`./mvnw install`).
|
||||
|
||||
=== Documentation
|
||||
|
||||
The spring-cloud-build module has a "docs" profile, and if you switch
|
||||
that on it will try to build asciidoc sources from
|
||||
`src/main/asciidoc`. As part of that process it will look for a
|
||||
`README.adoc` and process it by loading all the includes, but not
|
||||
parsing or rendering it, just copying it to `${main.basedir}`
|
||||
(defaults to `${basedir}`, i.e. the root of the project). If there are
|
||||
any changes in the README it will then show up after a Maven build as
|
||||
a modified file in the correct place. Just commit it and push the change.
|
||||
|
||||
=== Working with the code
|
||||
If you don't have an IDE preference we would recommend that you use
|
||||
http://www.springsource.com/developer/sts[Spring Tools Suite] or
|
||||
http://eclipse.org[Eclipse] when working with the code. We use the
|
||||
http://eclipse.org/m2e/[m2eclipse] eclipse plugin for maven support. Other IDEs and tools
|
||||
should also work without issue as long as they use Maven 3.3.3 or better.
|
||||
|
||||
==== Importing into eclipse with m2eclipse
|
||||
We recommend the http://eclipse.org/m2e/[m2eclipse] eclipse plugin when working with
|
||||
eclipse. If you don't already have m2eclipse installed it is available from the "eclipse
|
||||
marketplace".
|
||||
|
||||
NOTE: Older versions of m2e do not support Maven 3.3, so once the
|
||||
projects are imported into Eclipse you will also need to tell
|
||||
m2eclipse to use the right profile for the projects. If you
|
||||
see many different errors related to the POMs in the projects, check
|
||||
that you have an up to date installation. If you can't upgrade m2e,
|
||||
add the "spring" profile to your `settings.xml`. Alternatively you can
|
||||
copy the repository settings from the "spring" profile of the parent
|
||||
pom into your `settings.xml`.
|
||||
|
||||
==== Importing into eclipse without m2eclipse
|
||||
If you prefer not to use m2eclipse you can generate eclipse project metadata using the
|
||||
following command:
|
||||
|
||||
[indent=0]
|
||||
----
|
||||
$ ./mvnw eclipse:eclipse
|
||||
----
|
||||
|
||||
The generated eclipse projects can be imported by selecting `import existing projects`
|
||||
from the `file` menu.

||||

||||
== Contributing
|
||||
|
||||
Spring Cloud is released under the non-restrictive Apache 2.0 license,
|
||||
and follows a very standard Github development process, using Github
|
||||
tracker for issues and merging pull requests into master. If you want
|
||||
to contribute even something trivial please do not hesitate, but
|
||||
follow the guidelines below.
|
||||
|
||||
=== Sign the Contributor License Agreement
|
||||
Before we accept a non-trivial patch or pull request we will need you to sign the
|
||||
https://cla.pivotal.io/sign/spring[Contributor License Agreement].
|
||||
Signing the contributor's agreement does not grant anyone commit rights to the main
|
||||
repository, but it does mean that we can accept your contributions, and you will get an
|
||||
author credit if we do. Active contributors might be asked to join the core team, and
|
||||
given the ability to merge pull requests.
|
||||
|
||||
=== Code of Conduct
|
||||
This project adheres to the Contributor Covenant https://github.com/spring-cloud/spring-cloud-build/blob/master/docs/src/main/asciidoc/code-of-conduct.adoc[code of
|
||||
conduct]. By participating, you are expected to uphold this code. Please report
|
||||
unacceptable behavior to spring-code-of-conduct@pivotal.io.
|
||||
|
||||
=== Code Conventions and Housekeeping
|
||||
None of these is essential for a pull request, but they will all help. They can also be
|
||||
added after the original pull request but before a merge.
|
||||
|
||||
* Use the Spring Framework code format conventions. If you use Eclipse
|
||||
you can import formatter settings using the
|
||||
`eclipse-code-formatter.xml` file from the
|
||||
https://raw.githubusercontent.com/spring-cloud/spring-cloud-build/master/spring-cloud-dependencies-parent/eclipse-code-formatter.xml[Spring
|
||||
Cloud Build] project. If using IntelliJ, you can use the
|
||||
http://plugins.jetbrains.com/plugin/6546[Eclipse Code Formatter
|
||||
Plugin] to import the same file.
|
||||
* Make sure all new `.java` files to have a simple Javadoc class comment with at least an
|
||||
`@author` tag identifying you, and preferably at least a paragraph on what the class is
|
||||
for.
|
||||
* Add the ASF license header comment to all new `.java` files (copy from existing files
|
||||
in the project)
|
||||
* Add yourself as an `@author` to the .java files that you modify substantially (more
|
||||
than cosmetic changes).
|
||||
* Add some Javadocs and, if you change the namespace, some XSD doc elements.
|
||||
* A few unit tests would help a lot as well -- someone has to do it.
|
||||
* If no-one else is using your branch, please rebase it against the current master (or
|
||||
other target branch in the main project).
|
||||
* When writing a commit message please follow http://tbaggery.com/2008/04/19/a-note-about-git-commit-messages.html[these conventions],
|
||||
if you are fixing an existing issue please add `Fixes gh-XXXX` at the end of the commit
|
||||
message (where XXXX is the issue number).
