`@AutoConfigureWebTestClient` breaks when SpringMVC is on the classpath

[S1lentControl]

spring boot 2.0.0-RELEASE + spring-boot-starter-web-services 2.0.0.RELEASE
Tests with

@RunWith(SpringRunner::class)
@SpringBootTest
@AutoConfigureWebTestClient
class DemoApplicationTests {...

Application not started after adding spring-boot-starter-web-services to dependencies

Caused by: org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.test.web.reactive.server.WebTestClient]: Factory method 'webTestClient' threw exception; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'webHandler' available

@AutoConfigureWebTestClient is used to configure the reactive WebClient of Spring WebFlux. What is the link with web-services?

Can you please describe what you're trying to do?

[S1lentControl]

I have reactive spring-boot 2 appication and i need call external soap web-services in my service layer.

Sorry but that doesn't make much sense right now. Can you please share a sample that we can run that demonstrates what you are trying to do and the error you referenced in your original description?

I solved the problem by excluding spring-webmvc

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web-services</artifactId>
            <exclusions>
                <exclusion>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-starter-web</artifactId>
                </exclusion>
                <exclusion>
                    <groupId>org.springframework</groupId>
                    <artifactId>spring-webmvc</artifactId>
                </exclusion>
            </exclusions>
        </dependency>

@S1lentControl without a sample, we'll try to fix what we guess the problem is: the webflux and web-services starter in app with that test you shared.

Please don't use spring-boot-starter-web-services for a WS client. I agree it isn't super obvious, but this starter is meant to be used for a WS server. You can add the following to your build instead of the starter:

<dependency>
	<groupId>org.springframework</groupId>
	<artifactId>spring-oxm</artifactId>
</dependency>
<dependency>
	<groupId>org.springframework.ws</groupId>
	<artifactId>spring-ws-core</artifactId>
</dependency>

We'll look at why @AutoConfigureWebTestClient fails when Spring MVC is on the classpath.
