ClassNotFoundException: DefaultedPageable

Hi, I have recently migrated my springboot (version 2.3.1) app from springfox to springdoc openapi (version 1.4.1).

The app uses spring-boot-starter-data-elasticsearch and has some endpoints that receive Pageable as parameters and return a Page.

I’ve added those 2 dependencies

<!-- SpringDoc OpenApi -->
<dependency>
    <groupId>org.springdoc</groupId>
    <artifactId>springdoc-openapi-ui</artifactId>
    <version>1.4.1</version>
</dependency>
<dependency>
    <groupId>org.springdoc</groupId>
    <artifactId>springdoc-openapi-data-rest</artifactId>
    <version>1.4.1</version>
</dependency>

I am getting an exception whose stacktrace is shown below. It’s complaining that org.springframework.data.rest.webmvc.support.DefaultedPageable is missing.

Thanks in advance!

@OskarsPakers,

From your description, you don’t need to load springdoc-openapi-data-rest. (You will load unecessary beans related to spring-data-rest)

If you just need to enable the support of Pageable, you can just add the following line:

SpringDocUtils.getConfig().replaceWithClass(org.springframework.data.domain.Pageable.class, Pageable.class);

This is explained here: https://springdoc.org/ Section [Spring Data Rest support]

Also, a fix will be added to handle this case, for projects relying on springdoc-openapi-data-rest for Pageable Support.

Hey @bnasslahsen ! Exactly, that was the problem!

I’ve imported from org.springframework.data.domain.Pageable instead of org.springdoc.core.converters.models.

By setting the Pageable absolute class name in the 2nd argument of replaceWithClass method will avoid some confusion.

Best
