Spring Boot 2.6.0 / Spring Fox 3 – Failed To Start Bean ‘documentationpluginsbootstrapper’

The error message "Failed to start bean ‘documentationPluginsBootstrapper’" usually indicates a problem with the Swagger/OpenAPI documentation generation in a Spring Boot application using Springfox 3.x.

To resolve this issue, you can try the following steps:

  1. Check your pom.xml or build.gradle file to ensure that you have the correct dependencies for Springfox 3.x. Make sure that you have the correct version of springfox-swagger2 and springfox-boot-starter dependencies.

For example, in Maven, you can include the following dependencies:

<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-boot-starter</artifactId>
    <version>3.0.0</version>
</dependency>

<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-swagger2</artifactId>
    <version>3.0.0</version>
</dependency>
  1. If you have recently upgraded from an older version of Springfox, ensure that you have removed any deprecated or incompatible configuration classes or annotations.

  2. Check your Spring configuration classes and make sure that you have the necessary configurations for Swagger/OpenAPI documentation. You may need to add or update the @EnableSwagger2 annotation or the equivalent configuration for Springfox 3.x.

  3. If you are using Spring Boot, ensure that the necessary auto-configuration classes are enabled. In most cases, Spring Boot should automatically detect and configure Springfox based on the presence of the springfox-boot-starter dependency.

  4. If the issue persists, try cleaning and rebuilding your project to ensure that all the dependencies are correctly resolved.

If none of these steps fix the issue, you may need to provide more specific details about your application setup and configuration for further troubleshooting.
