Avoiding default basic-error-controller from swagger api

Question

I'm using swagger2 in my spring boot project. It's working well, but I need to exclude the basic-error-controller from the api. Currently I'm using the following code using regex. It's working but is there any perfect way to do this.

CODE :

@Bean
public Docket demoApi() {
    return new Docket(DocumentationType.SWAGGER_2)
            .select()
            .apis(RequestHandlerSelectors.any())
            .paths(PathSelectors.regex('(?!/error.*).*'))
            .build()
}

After searching in google I got the solution from one issue in GitHub, [question] How to exclude the basic-error-controller from being added to the swagger description?. It can be done using Predicates.not().

Code looks like as follows after using Predicates.not().

@Bean
public Docket demoApi() {
    return new Docket(DocumentationType.SWAGGER_2)//<3>
            .select()//<4>
            .apis(RequestHandlerSelectors.any())//<5>
            .paths(Predicates.not(PathSelectors.regex("/error.*")))//<6>, regex must be in double quotes.
            .build()
}
