Parameter 2 of method indexPageTransformer in org.springdoc.webmvc.ui.SwaggerConfig required a single bean, but 2 were found:

When there are two types of beans, JsonMapper and XmlMapper, an error will be reported

  @Bean
  protected XmlMapper xmlMapper() {
    return new XmlMapper();
  }

  @Bean
  protected JsonMapper jsonMapper() {
    return new JsonMapper();
  }

@walnut-tom,

If you want to use your own objectMapper, the simplest way to override the default configuration is to define an ObjectMapper bean and to mark it as @Primary.

We will improve this anyway.
