Multiple swagger-ui html pages in a spring application - spring

Question

I am building an application where I would like to have two swagger urls:
http://localhost:8080/order-swagger.ui.html
http://localhost:8080/inventory-swagger.ui.html
I read many articles but did not find any solution.
What I found is that to define two docket beans but it does not effectively build two html pages. It creates 2 items in the upper right corner dropdown.
Much appreciated if you could provide how to do it.

Along with the two Docket beans, you could add a couple of URL redirection rules to route /order-swagger.ui.html and /inventory-swagger.ui.html to /swagger-ui.html with the correct group selected. I defined a WebMvcConfigurer bean to do the redirection and then I got the two separate URLs, http://localhost:8080/order-swagger.ui.html and http://localhost:8080/inventory-swagger.ui.html available showing the API definitions of /order and /inventory endpoints respectively. Bean definitions below:
#Bean
public Docket orderDocket() {
return new Docket(DocumentationType.SWAGGER_2)
.groupName("order")
.select().paths(path -> path.endsWith("/order"))
.build();
}
#Bean
public Docket inventoryDocket() {
return new Docket(DocumentationType.SWAGGER_2)
.groupName("inventory")
.select().paths(path -> path.endsWith("/inventory"))
.build();
}
#Bean
public WebMvcConfigurer webMvcConfigurer() {
return new WebMvcConfigurer() {
#Override
public void addViewControllers(ViewControllerRegistry registry) {
registry.addRedirectViewController("order-swagger.ui.html", "/swagger-ui.html?urls.primaryName=order");
registry.addRedirectViewController("inventory-swagger.ui.html", "/swagger-ui.html?urls.primaryName=inventory");
}
};
}
