org.springframework.cloud.config.server.bootstrap

Class ConfigServerBootstrapApplicationListener

java.lang.Object

org.springframework.cloud.config.server.bootstrap.ConfigServerBootstrapApplicationListener

All Implemented Interfaces:

EventListener, org.springframework.context.ApplicationListener<org.springframework.boot.context.event.ApplicationEnvironmentPreparedEvent>, org.springframework.core.Ordered

public class ConfigServerBootstrapApplicationListener
extends Object
implements org.springframework.context.ApplicationListener<org.springframework.boot.context.event.ApplicationEnvironmentPreparedEvent>, org.springframework.core.Ordered

Normally you don't want the config server to be a config client itself, so this listener disables the config client unless spring.cloud.config.enabled is explicitly "true". It has to be "true" at the time this listener is fired, which means before the bootstrap.yml is parsed, which in turn means to you need to launch the application with an existing primed Environment (e.g. via System properties or a SpringApplicationBuilder). This is the same rule of precedence as for anything else affecting the bootstrap process itself, e.g. setting spring.cloud.bootstrap.name to something other than "bootstrap".

N.B. a config server can always be an "embedded" config client (using its own config repository as a property source) if you set spring.cloud.config.server.bootstrap=true in bootstrap.yml bootstrap.yml. This listener is only to prevent it from using HTTP to contact itself.
