No spring.config.import property has been defined

Solution for Maven

Add the below dependency in the pom.xml file:

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-bootstrap</artifactId>
</dependency>

Solution for Gradle

Add in the build.gradle file:

implementation('org.springframework.cloud:spring-cloud-starter-bootstrap')

That resolved my issue.

You're getting this error because you're using a new version of Spring Boot and Spring Cloud, but you're trying to configure it in the old way.

The Reason

Spring Cloud Config Client has changed and technically bootstrap.properties and bootstrap.yml files are deprecated.

Correct Solution

1. Move all properties from boostrap.properties to application.properties (it can be .yml as well)
2. Remove bootstrap.properties file
3. Replace spring.cloud.config.uri=http://localhost:8888 with spring.config.import=configserver:http://localhost:8888

This is a proper way to tell you Spring Boot app that you want to load properties from the Spring Cloud Config service that is running on localhost:8888.

Legacy Solution

In case you want to use a legacy bootstrap.properties file, you just need to add the following dependency:

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-bootstrap</artifactId>
</dependency>

Please note that this is a deprecated mechanism, so if you're creating a new project, go ahead with the correct solution.

Root cause is Spring Boot 2.4 changed its default functionality. A new spring.config.import property is mandatory.

To fix, add the new spring.config.import property. Here is an example of what worked for me in application.yml.

spring:
  config:
    import: "optional:configserver:"

Here is the documentation in case you need to set a different value:

Spring Boot Config Data Import

Spring Boot 2.4 introduced a new way to import configuration data via the spring.config.import property. This is now the default way to bind to Config Server.

Importing configuration since Spring Boot 2.4 is done by spring.config.import functionality.

Adding below to application.properties connects to the default config server URL http://localhost:8888.

spring.config.import=optional:configserver:

or yml:

spring.config.import: "optional:configserver:"

More configuration options are described in the reference documentation.

Legacy bootstrap functionality is still available if you add the org.springframework.cloud:spring-cloud-starter-bootstrap dependency to your project.

Add bootstrap.yml file:

spring:
    cloud:
      config:
        enabled: true
        uri: http://localhost:9296

where 9296 is your cloud-config server port

and add below dependency:

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-bootstrap</artifactId>
</dependency>

If above doesn't work, simply add below properties to your application.yml file to stop the port check at place as you've already defined that in bootstrap.yml

spring:
    cloud:
      config:
        import-check:
          enabled: false

I was getting this issue while implementing spring-cloud-config client. I have added bootstrap.yml to specify config server address.

Later on, added the below code in application.yml itself which resolved the issue.

spring:
   application:
    name: user-service
   config:
     import: optional:configserver:http://localhost:9004

Error message itself has suggestions / action towards the solution:

Add a spring.config.import=configserver: property to your configuration.

If configuration is not required add spring.config.import= optional:configserver: instead.

To disable this check, set spring.cloud.config.enabled=false 

or

spring.cloud.config.import-check.enabled=false.

Adding this dependency resolved my issue too: spring-cloud-starter-bootstrap

I got past the error by removing dependency spring-cloud-starter-config. If you keep it, then it will keep prompting. I think with newer Spring Boot we do not need the dependency.

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-config</artifactId>
</dependency>

bootstrap.properties:

spring.application.name=config-client-app
eureka.client.server-url.defaultZone=http://localhost:8761/eureka
spring.config.import=optional:configserver:

Spring version I'm working with:

<spring-cloud.version>2020.0.3</spring-cloud.version>

I'm using Spring Cloud Config Server on port 8888 on localhost, Spring version 2.5.4 and Java 16

My bootstrap.properties:

spring.application.name=hr-worker
# Server Config
spring.cloud.config.enabled=true
spring.cloud.config.uri= http://localhost:8888

To stop to get error, i've just put this configuration in my application.properties:

spring.config.import=optional:configserver:http://localhost:8888

I got past the error using a version of spring 2.4.4 I was working in that moment with 2.5.1

application.properties:

`
spring.application.name=testserv
spring.profiles.active=prodtest
spring.config.import=optional:configserver:http://localhost:8071

spring.cloud.config.enabled=true
spring.cloud.config.uri=http://localhost:8071

management.endpoints.web.exposure.include=*

eureka.instance.preferIpAddress = true 
eureka.client.registerWithEureka = true
eureka.client.fetchRegistry = true
eureka.client.serviceUrl.defaultZone = http://localhost:8070/eureka/

`

<spring-cloud.version>2020.0.3</spring-cloud.version>

In SpringBoot v2.7.1 this solution worked for me:

My Microservice bootstrap.properties file:

spring.application.name=microservice-name
spring.cloud.config.uri=http://localhost:8888 # the URL of your server configuration

And add the following dependency:

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-bootstrap</artifactId>
</dependency>

If anybody is passing this error on spring-boot 2.7.0 version during tests phase put the following on src/test/application.properties

spring.cloud.config.enabled=false

If don't want to use config server for tests.

Just import this dependency in pom.xml

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-bootstrap</artifactId>
</dependency>

For spring version > 2.6.6 add below property in application.property.

spring.application.name=... //name of application

spring.profiles.active=prodtest

spring.config.import=optional:configserver:http://localhost:8071

spring.cloud.config.enabled=true

spring.cloud.config.uri=http://localhost:8071

management.endpoints.web.exposure.include=*

eureka.instance.preferIpAddress = true

eureka.client.registerWithEureka = true

eureka.client.fetchRegistry = true

eureka.client.serviceUrl.defaultZone = http://localhost:8070/eureka/
