What is YAML?

YAML is a human readable serialization language

YAML stands for Yet Another Markup Language

Let’s consider an example

application.properties

level1.property1 = 5
level1.property2 = 6
level1.property3 = 7
level1.level2.property4 = 8
level1.level2.property5 = 10
level1.level2.property6 = 11

Above property file is cool but it is not very readable.

Let’s consider the same example in YAML format: application.yaml

level1:
  property1: 5
  property2: 6
  property3: 7
  level2:
     property4: 8
     property5: 10
     property6: 11

YAML

  • is concise
  • is more readable

Spring Boot and YAML

Spring Boot has excellent support for YAML configuration.

Example 1

application.properties

server.port = 9080

application.yaml

server:
	port: 9080

Example 2

application.properties

app.name=in28Minutes
app.description=${app.name} is your first Spring Boot application
welcome.message=Welcome message from property file! Welcome to ${app.name}

application.yaml

app:
   name: In28Minutes
   description: ${app.name} is your first Spring Boot application
welcome:
    message: Welcome to your first Spring Boot app!

Example 3 - Dynamic Configuration

application.properties

basic.value: true
basic.message: Dynamic Message
basic.number: 100

application.yaml

basic: 
   value: true
   message: Dynamic Message YAML
   number: 100
