在Cloud Foundry中将Java应用程序绑定到MySQL

Question

I'm trying to bind MySQL service, which is in on prem cloud foundry, to my Java application. could anyone suggest me what are the necessary changes to be made in my code to access MySQL database.

Answer 1

If you are using Spring Boot, this should happen almost automatically as described in a Spring blog post .

If you are using Spring without Spring Boot, you may want to use Spring Cloud Connectors .

If you are using neither, you can interrogate the VCAP_SERVICES environment variable for details of your service.

Answer 2

On cloud foundry, you will have to provision a service for your app.

Look for available services.

cf marketplace

Identify the mysql service and the plan. Create the service instance

cf create-service p-mysql 512mb mysql

To see the service instances

cf services

Bind the service instance to your app

cf bind-service myapp mysql

You can see the details as

cf env myapp

EngineerBetter has already provided you articles on how to use Spring to leverage the service in your app code.

Here's a good quick reference for CF CLI
