Issue description

When the annotation @SpringBean with Spring Cloud OpenFeign and SpEL is used then Spock refreshes Spring context and ConfigurationPropertiesBindingPostProcessor is not registered (also some other BeanPostProcessors are not registered as well), so, in my case, a value from the property test of ApplicationProperties.java is NOT replaced with a value of a propertyapplication.test from application-test.properties.

When the annotation @SpringBean is not used then the context is loaded with the post processor.

How to reproduce

ApplicationProperties.java

import lombok.Getter;
import lombok.Setter;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;

@Getter
@Setter
@Component
@ConfigurationProperties(prefix = "application")
public class ApplicationProperties {
    private boolean test = true;
    private String url;
}

application-test.properties

application.test=false
application.url=localhost:7080

AnotherAppRestClient.java

@FeignClient(name = "another-app", url = "#{applicationProperties.url}")
public interface AnotherAppRestClient {...}

ApplicationSpec.groovy

import org.spockframework.spring.SpringBean
import org.springframework.beans.factory.annotation.Autowired
import org.springframework.boot.test.context.SpringBootTest
import spock.lang.Specification

@SpringBootTest
class LotteryApplicationSpec extends Specification {

    @Autowired
    private ApplicationProperties applicationProperties

    @SpringBean
    MyService myService = Mock()

    def "Application context is properly created"() {
        expect:
        applicationProperties.test == false
    }
}

When the anntation @SpringBean with the service is commented then the test passes.

It also works when I rewrite the Feign client with value replacement instead of SpEL for url parameter of the FeignClient annotation:

@FeignClient(name = "another-app", url = "${application.url}")
public interface AnotherAppRestClient {...}

Workaround

Use ${application.url} instead of #{applicationProperties.url}
