The mappings endpoint provides information ;about different service endpoints that are exposed from the application:

• URI
• Request methods
• Bean
• Controller methods exposing the service

Mappings provides ;a collated list of all @RequestMapping paths. An extract from the response of the /application/mappings endpoint is shown here. ;We can see mappings of the different controller methods that were created earlier in this book:

"{[/welcome-internationalized],methods=[GET]}": {
   "bean": "requestMappingHandlerMapping",
   "method": "public java.lang.String 
    com.mastering.spring.springboot.controller.
