WebTestClient.bindToRouterFunction(...) with exception handler not working [SPR-17239]

[spring-projects-issues]

rodolphocouto opened SPR-17239 and commented

This bug occurs when the WebTestClient is used to test a router function with custom exception handler, for example:

 

WebTestClient
    .bindToRouterFunction(myRouter())
    .handlerStrategies(HandlerStrategies.builder()
        .exceptionHandler(new CustomExceptionHandler()) // IS NOT CALLED :(
        .build())
    .build()

 

 

With annotated controllers, the same custom exception is called, for example:

 

WebTestClient
    .bindToController(new MyController())
    .controllerAdvice(new CustomExceptionHandler()) // IS CALLED :)
    .build()

Affects: 5.0.8

Looks like several options in HandlerStrategies were added later, but bindToRouterFunction was never updated. This should be fixed now in master for 5.1.1.
