Why HATEOAS starts creating issue for spring-boot version >= 2.2.x during startup with Swagger 2.x?

Question

I moved my project from spring-boot 2.1.9 to 2.2.0.

While starting the project, I am facing the below error messages.

Answer 1

This kind of issue is occurring due to a new feature of Hateoas.

If you want to solve this problem , just embed the following line of codes in your swagger configuration file.

@Primary
@Bean
public LinkDiscoverers discoverers() {
    List plugins = new ArrayList<>();
    plugins.add(new CollectionJsonLinkDiscoverer());
    return new LinkDiscoverers(SimplePluginRegistry.create(plugins));
}

I think this is gonna solve your problem as it solved mine.
