This project provides an API Gateway built on top of the Spring Ecosystem, including: Spring 5, Spring Boot 2 and Project Reactor. Spring Cloud Gateway aims to provide a simple, yet effective way to route to APIs and provide cross cutting concerns to them such as: security, monitoring/metrics, and resiliency.
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.
==== Adding Project Lombok Agent
Spring Cloud uses http://projectlombok.org/features/index.html[Project Lombok]
to generate getters and setters etc. Compiling from the command line this
shouldn't cause any problems, but in an IDE you need to add an agent
to the JVM. Full instructions can be found in the Lombok website. The
sign that you need to do this is a lot of compiler errors to do with
missing methods and fields, e.g.
[indent=0]

==== Importing into Intellij
Spring Cloud projects use annotation processing, particularly Lombok, which requires configuration
or you will encounter compile problems. It also needs a specific version of maven and a profile
enabled. Intellij 14.1+ requires some configuration to ensure these are setup properly.
1. Click Preferences, Plugins. *Ensure Lombok is installed*
2. Click New, Project from Existing Sources, choose your spring-cloud project directory
3. Choose Maven, and select Environment Settings. *Ensure you are using Maven 3.3.3*
4. In the next screen, *Select the profile `spring`* click Next until Finish.
