让我们试试这个，我从github上找到了这个代码

import io.swagger.v3.oas.models.OpenAPI;
import io.swagger.v3.oas.models.servers.Server;
import io.swagger.v3.oas.models.servers.ServerVariable;
import io.swagger.v3.oas.models.servers.ServerVariables;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class OpenApiGeneratorConfig {

    @Bean
    public OpenAPI defineOpenApi() {
        return new OpenAPI()
                .info(defineInfo())
                .components(defineComponents())
                .addServersItem(defineServers());
    }

...

    private Server defineServers() {
        return new Server().url("http://{IP_Address}:8080/my-app")
                           .description("My APP REST API Server")
                           .variables(
                                   new ServerVariables().addServerVariable("IP_Address", new ServerVariable()
                                           //._default("www.example.com")
                                           ._default("localhost")
                                           .description("IP address of My APP REST API Server")
                                   )
                           );
    }
}
