predix-microservice-cf-jsr

This project is a cloud-ready microservice that demonstrates how to create JSR - CXF based Services. You simply change the @Path url and begin adding your service implementation. It has SpringBoot, Spring Profiles and Property file management configured and ready for local development vs. cloud deployment. It is also set up for Test Driven Development with JUnit and Mockito.

The template has the following structure and can be used for any Predix microservice.

To Download and Push predix-microservice-cf

1. Download a DevBox and launch it in Virtual Box or install the Dependencies

2. Prepare your environment and follow the steps below to get up and running on Cloud Foundry.

3. Download the project

$ git clone https://github.com/PredixDev/predix-microservice-cf-jsr.git  

$ cd predix-microservice-cf-jsr

$ mvn clean package  

  note: mvn clean install may run integration tests against services you may not have set up yet

4. To load in eclipse (you may skip to 'Push to Cloud' if desired)

Vanilla Eclipse or [Eclipse STS - Springsource Tool Suite(https://spring.io/tools/sts/all) are both supported

$ mvn eclipse:clean eclipse:eclipse  

File/Import/General/Existing Projects/Browse to predix-microservice-cf dir  

Check the box 'Search for nested projects'  

5. Try it out locally

in Eclipse - Right Click predix-microservice-cf project / Run As / Application 
in Eclise STS - Right Click predix-microservice-cf project / Run As / Spring Boot Application 

Visit service at http://localhost:9092 - a Spring RestTemplate  

and http://localhost:9092/services/ping - a CXF Rest Endpoint  

and http://localhost:9092/services?_wadl - a CXF Rest descriptor

6. Push to cloud

   Take a look at the predix-microservice-cf manifest.yml which provides properties and instructions for pushing cloud foundry apps

$ cf push  

visit http://(cloud-url-here)/services/ping - get the url from the output of cf push  

Troubleshooting

If you encounter a github acct/password issue then contact predixgithubaccount@ge.com.

If you encounter a corporate proxy issue, you might need to set up your env vars as required by your IT department.

If you encounter a maven or artifactory account issue, add your predix.io username and encrypted password to a maven ~/.m2/settings.xml file on your laptop. It should be setup already if in a DevBox.

Preparation

Predix Microservice CF accesses code repos at https://github.com/PredixDev.

The best experience is to use a DevBox which has all the tools and settings pre-installed.

• In DevBox,

  • add your encrypted predix.io username and password to the ~/.m2/settings.xml by replacing predixuser@ge.com with your Predix.io user and pass.

  • to avoid entering user/pass several times, run this command to cache it

  git config --replace-all --global credential.helper 'cache --timeout=7200'
  

  • OSX: To enable Copy/Paste using Left Command key.

    On Host: Please choose VirtualBox/Preferences/Input/Virtual Machine/Host Key Combination.  
    Set to Right ⌘.  
    On VM: Choose System/Preference/Keyboard/Layouts/Layout Options/Alt/Win Key Behavior/Ctrl is mapped to Win Keys(and the usual Ctrl keys)
  

  We have a second DevBox for GE employees which helps with corporate proxy settings.

  In your own IT environment you may need to configure the proxy settings Environment variables within the VM or your own laptop.

• For non-DevBox users,
  For users wanting to install all the tools, please reference the DevBox settings, and also ensure you have the prerequisites installed from Predix.io Getting Started documentation.

  • add your encrypted predix.io username and password to the ~/.m2/settings.xml by replacing predixuser@ge.com with your Predix.io user and pass.

  • to avoid entering user/pass several times, run this command to cache it

  git config --global credential.helper cache --timeout=7200
