Control the content of error attributes

[aoudiamoncef]

Description

There is an interesting feature in Spring Boot which controls easily error attributes.

Default configuration:

server:
  error:
    include-stacktrace: never
    include-message: never
    include-binding-errors: never
    include-exception: off

ErrorAttributeOptions could be reused easily in custom application configuration properties

I saw exception-mapping

Implementation ideas

Implementation -> BasicErrorController

To see it in action:

1. generate a simple Spring Boot project with this link

2. create a GET endpoint /boom which throws an exception

3. call /boom and see the response(properties includes/excludes)

4. tweak server configuration:

server:
  error:
    include-stacktrace: always
    include-message: always

5. check returned response if it includes message + stacktrace

It s a good idea in cases we have large amount of logs.

This indeed seems like an interesting feature. Do you know how widely used it is in Spring Boot?

Seems interesting. Related (a bit) to #13662.
