[springboot 3.3.7 or >= 3.4.0] Required a bean of type 'org.springframework.data.rest.webmvc.mapping.Associations' that could not be found.

[gquintillan]

Describe the bug
When I upgrade from SpringBoot 3.3.6 to 3.3.7 (with springdoc-openapi 2.6.0) or 3.4.1 (with springdoc-openapi 2.7.0) I get the following error:

***************************
APPLICATION FAILED TO START
***************************

Description:

Parameter 2 of method springRepositoryRestResourceProvider in org.springdoc.core.configuration.SpringDocDataRestConfiguration$SpringRepositoryRestResourceProviderConfiguration required a bean of type 'org.springframework.data.rest.webmvc.mapping.Associations' that could not be found.

This is the stacktrace when I set debug: true in the application.yml:

To Reproduce
Steps to reproduce the behavior:

• What version of spring-boot you are using?: 3.3.7 or >= 3.4.0
• What modules and versions of springdoc-openapi are you using?: springdoc-openapi-starter-webmvc-ui 2.6.0 2.7.0
• Provide with a sample code (HelloController) or Test that reproduces the problem:

In the Main class (@SpringBootApplication) I'm using the following Beans:

• import io.swagger.v3.oas.models.Components;
• import io.swagger.v3.oas.models.OpenAPI;
• import io.swagger.v3.oas.models.info.Info;
• import org.springdoc.core.models.GroupedOpenApi;

In the Rest Controller (@RestController) I'm using the following annotations:

• import io.swagger.v3.oas.annotations.Operation;
• import io.swagger.v3.oas.annotations.tags.Tag;

Expected behavior
The application starts without errors.

Additional context
The application is a SpringBoot Application with Spring Data Rest and Spring Data Elastic Search

I encounter the same behavior with Spring Boot 3.4.1, though it works fine with 3.4.0. That said, I can resolve under 3.4.1 if I override spring-data-rest-webmvc with version 4.4.0. It's version 4.4.1 that appears incompatible with Springdoc 2.7.0.

I should mention one oddity. Of two of my apps that use Springdoc 2.7.0, one works fine with Spring Boot 3.4.1 and the other doesn't. It's not clear to me what the difference is?

[MarkusRohlof]

Same issue here. Overriding spring-data-rest-webmvc with 4.4.0 worked for me as well.

[jkjome]

I believe the problem is related to spring-boot-devtools. If said dependency is removed from the POM, the app runs fine in the IDE. Also, JUnit test running is unaffected either way. The same is true for running as a plain old Jar app... outside the context of an IDE. And the only difference, of any consequence, between v4.4.0 and v4.4.1 of spring-data-rest-webmvc is the introduction of file META-INF/spring-devtools.properties, with contents...

restart.include.spring-data-rest-webmvc:/spring-data-rest-webmvc-[\\w-\\.]+\.jar

That said, I don't know why the above results in the unfortunate Dev Tools behavior.

[gquintillan]

Thank you for the feedback, I can confirm that it only happens when running the application with spring-boot-devtools, when I run the JAR the problem does not occur. Moreover, if I remove the dependency spring-boot-devtools I have no issues when running the application with ./mvnw spring-boot:run or the IDE.

The commit from spring-data-rest says:

We now declare explicit Spring Boot DevTools configuration to include Spring Data REST WebMVC and HAL Explorer in the restart classloader to prevent proxying issues with package protected types.
