# --- Spring Configuration for Vault and Database ---
spring:
# 1. New Config Import Structure: Tells Spring to load properties from Vault first.
config:

# 2. Vault Configuration (Using static values prevents the StackOverflowError)
cloud:
vault:
enabled: true
uri: ${VAULT_ADDR:http://localhost:8200}
token: ${VAULT_TOKEN:my-root-token}
kv:
enabled: true

default-context: cs02-app
authentication: TOKEN

# 3. Application Name
application:
name: cs02-app

# 4. Data Source Configuration
datasource:
# URL is static. 'localhost' is correct.
url: jdbc:postgresql://localhost:5432/CSO2_user_identity_service

# 5. The Secrets! These placeholders are filled by Vault at runtime.
