Configuration Properties

Below you can find a list of configuration properties.

Name Default Description

spring.cloud.compatibility-verifier.compatible-boot-versions

3.4.x

Default accepted versions for the Spring Boot dependency. You can set {@code x} for the patch version if you don’t want to specify a concrete value. Example: {@code 3.4.x}

spring.cloud.compatibility-verifier.enabled

false

Enables creation of Spring Cloud compatibility verification.

spring.cloud.config.allow-override

true

Flag to indicate that {@link #isOverrideSystemProperties() systemPropertiesOverride} can be used. Set to false to prevent users from changing the default accidentally. Default true.

spring.cloud.config.initialize-on-context-refresh

false

Flag to initialize bootstrap configuration on context refresh event. Default false.

spring.cloud.config.override-none

false

Flag to indicate that when {@link #setAllowOverride(boolean) allowOverride} is true, external properties should take lowest priority and should not override any existing property sources (including local config files). Default false. This will only have an effect when using config first bootstrap.

true

Flag to indicate that the external properties should override system properties. Default true.
