[FIXED] Adding custom request header to every API in spring boot

Issue

I am trying to add custom request header to every API I can do it by adding a piece of code to every API

`public ResponseDTO setNames(@RequestHeader(value="my-header",required = false HttpServletRequest httpServletRequest) throws Exception {}`

But I want this to be done automatically like we have authorisation header by default when we create a new API.How can this be done can anyone tell me a good solution

enter image description here

Solution

You can use the following if you are using springdoc-openapi

@Configuration
class CustomizeSpringDoc {
    @Bean
    fun publicApi(): GroupedOpenApi {
        return GroupedOpenApi.builder()
            .group("add-auth-header")
            .addOperationCustomizer { operation, handlerMethod ->
                operation.parameters.add(
                    HeaderParameter()
                        .name("Authorization")
                        .description("Access Token")
                )
                operation
            }
            .build()
    }
}

If you are using spring-fox, you can refer back to the below link, globalRequestParameters: http://springfox.github.io/springfox/docs/current/#quick-start-guides
