Spring Boot - Application Configuration

You want to migrate your Spring Boot app configuration from application.yml to application.properties. Which of the following is the correct way to convert this YAML snippet?

server:
  port: 9090
spring:
  datasource:
    url: jdbc:h2:mem:testdb
    username: sa
    password: ""

Aserver.port=9090 spring.datasource.url=jdbc:h2:mem:testdb spring.datasource.username=sa spring.datasource.password=

Bserver.port : 9090 spring.datasource.url : jdbc:h2:mem:testdb spring.datasource.username : sa spring.datasource.password : ""

Cserver.port => 9090 spring.datasource.url => jdbc:h2:mem:testdb spring.datasource.username => sa spring.datasource.password => ""

Dserver.port9090 spring.datasource.urljdbc:h2:mem:testdb spring.datasource.usernamesa spring.datasource.password""

Step-by-Step Solution

Solution:

Step 1: Understand YAML to properties conversion
YAML uses indentation and colons, while properties files use dot notation and equals signs.
Step 2: Convert nested YAML keys to dot notation with =
The nested keys become dot-separated keys, and values are assigned with equals signs. Empty password is represented by an empty value.
Final Answer:
server.port=9090 spring.datasource.url=jdbc:h2:mem:testdb spring.datasource.username=sa spring.datasource.password= -> Option A
Quick Check:
YAML nesting = dot notation + = in properties [OK]

Quick Trick: Convert YAML nesting to dot keys with = [OK]

Common Mistakes:

Using colon instead of equals in properties
Using arrows or spaces instead of =
