Groovy Question

How to configure a default @RestController URI prefix for all controllers?

I know you can set the

server.contextPath
in
application.properties
to change the root context.

Also, I can add an additional context in the application config for Spring Boot like the following example (in Groovy) to add an "/api" to the URL mappings of the root context:

@Bean
ServletRegistrationBean dispatcherServlet() {
ServletRegistrationBean reg = new ServletRegistrationBean(new DispatcherServlet(), "/")
reg.name = "dispatcherServlet"
reg.addInitParameter("contextConfigLocation", "")
reg.addUrlMappings("/api/*")
reg.loadOnStartup = 2
reg
}
}


I am trying to have a separate base URI "/api" specifically for web service calls, that I can leverage for security, etc. However using the above approach will mean that any of my URIs, web service or not, can be reached with "/" or "/api", and provides no concrete segregation.

Is anyone aware of a better approach to set a base path for all
@RestController
(s) using configuration, without having to formally prefix every controller with /api/? If I am forced to manually prefix the URI for each controller, it would be possible to mistakenly omit that and bypass my security measures specific to web services.

Here is a reference in Stack Overflow to the same type of question, which was never completely answered:

Spring Boot: Configure a url prefix for RestControllers

Answer

Someone has filed an issue in the Spring MVC Jira and come up with a nice solution, which I am now using. The idea is to use the Spring Expression Language in the prefix placed in each RestController file and to refer to a single property in the Spring Boot application.properties file.
