I want to read a property from application.properties and set as default value to @RequestHeader to an API endpoint. My properties look like item.includePrice.value=Y

ItemController.java

@PostMapping("/item")
public String postBody(@RequestHeader String includePrice, @RequestBody SomeRequest someRequest) {
   if(includePrice != null) 
       return "You searched for " + someRequest.getItemName;
}

I have referred below questions and tried two approaches.

First approach is, tried using a custom interceptor. But, in order to set the default value for includePrice after reading the property from application.properties under the preHandle method, I do not see addHeader method for HttpServletRequest.

Application Properties value in Spring boot interceptor

Second approach is used below resources and implemented a MutableHttpServletRequest that extends HttpServletRequestWrapper and added the header.

Adding an HTTP Header to the request in a servlet filter

How to add HttpServletRequest headers in HandlerInterceptorAdapter?

Expectation: Regardless the API request sends the includePrice header value or not, at all times, the property should be read from the application.properties and set the default value to my HttpServletRequest.

  • Couldn't you just define the header as optional and handle it within your application code? – Dinosaur-Guy Jan 13 '23 at 06:51
  • I can, but my requirement is to read all the global properties and set it to the request instead of setting the default value in @RequestHeader – psprogrammer Jan 13 '23 at 16:52
