Question

I have the follwoing spring boot configuration for swagger, when service starts up i get the following error, im not sure exactly why this would be the case. I have followed a tutorial and it works for them.
java.lang.IllegalStateException: Multiple Dockets with the same group name are not supported. The following duplicate groups were discovered. default
#Configuration
#EnableSwagger2
#Import(BeanValidatorPluginsConfiguration.class)
public class SpringFoxConfig {
#Bean
public Docket apiDocket() {
return new Docket(DocumentationType.SWAGGER_2)
.select()
.apis(RequestHandlerSelectors.basePackage("test.rest"))
.paths(PathSelectors.ant("/test/**"))
.build()
.apiInfo(apiInfo());
}
// Describe the apis
private ApiInfo apiInfo() {
return new ApiInfoBuilder()
.title("test")
.description("Test")
.version("1.0.0")
.license("vvv")
.build();
}
}
i also have another config
#OurApp
#EnableSwagger2
public class CoreApp extends OurApp {
}

Here you are trying to do multiple Dockets with the same group name, which is not acceptable. Please review the link provided.
groupName(java.lang.String groupName) If more than one instance of
Docket exists, each one must have a unique groupName as supplied by
this method. Documentation
public class Docket implements DocumentationPlugin {
public static final String DEFAULT_GROUP_NAME = "default";
}
You can see above DocumentPlugin has groupname as "default".
public Docket(DocumentationType documentationType) {
this.apiInfo = ApiInfo.DEFAULT;
this.groupName = "default";
And above has "default" as group name.
So, you need to have two different group names for both the Dockets.
All you need to do is change your code as below: overwrite the existing default groupname.
#Configuration
#EnableSwagger2
#Import(BeanValidatorPluginsConfiguration.class)
public class SpringFoxConfig {
#Bean
public Docket apiDocket() {
String groupName = "Swagger";
return new Docket(DocumentationType.SWAGGER_2)
.select()
.apis(RequestHandlerSelectors.basePackage("test.rest"))
.paths(PathSelectors.ant("/test/**"))
.build()
.groupName(groupName)
.apiInfo(apiInfo());
}
// Describe the apis
private ApiInfo apiInfo() {
return new ApiInfoBuilder()
.title("test")
.description("Test")
.version("1.0.0")
.license("vvv")
.build();
}
}

Seems like you have given the same group name which is not accepted, please check and set the group name properly.
