Reactive Spring does not support ServerHttpRequest as parameter in REST endpoint tests?

Cherry :

The question is very similar to this one. Except the fact that I use:

1. org.springframework.http.server.ServerHttpRequest not HttpServletRequest.
2. The exception is got in test code. Real calls works.

Code:

@RunWith(SpringRunner.class)
@SpringBootTest(classes = SecurityTests.SecurityTestsApplication.class)
@TestPropertySource(properties = {""})
@AutoConfigureWebTestClient
public class SecurityTests {
        @Test 
        public void myTest() { 
            //send request to myUrl and got 500 
        }
}

@RestController
@RequestMapping("/myPath")
public class MyController {
    @PostMapping
    public Mono<Void> myMethod(ServerHttpRequest request) {
        return Mono.empty()
    }

}

Exception is:

java.lang.IllegalStateException: Failed to resolve argument 1 of type 'org.springframework.http.server.ServerHttpRequest' on public reactor.core.publisher.Mono<java.lang.Void> MyController$MockitoMock$606550817.myMethod(org.springframework.http.server.ServerHttpRequest)

Brian Clozel :

You've imported the wrong class:

• org.springframework.http.server.ServerHttpRequest is for Spring MVC
• org.springframework.http.server.reactive.ServerHttpRequest is for Spring WebFlux
