弹簧ReactiveWeb！添加Swagger 2文档后,Netty没有启动
作者：互联网
Swagger是否支持Spring Reactive-Web？
我正在尝试使用Reactive Web和Reactive Mongo编写一个简单的crud应用程序.一切正常.但是当我将Swagger添加到我的项目中时,Netty无法启动.
这是我的控制器类：
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RestController;
import reactor.core.publisher.Flux;
import reactor.core.publisher.Mono;
import uz.n0d1r.datas.Point;
import uz.n0d1r.repository.PointRepository;
@RestController(value = "/points")
public class PointController {
private final PointRepository pointRepository;
public PointController(PointRepository pointRepository) {
this.pointRepository = pointRepository;
}
@PostMapping
Mono<Void> create(@RequestBody Point point) {
return pointRepository.save(point).then();
}
@GetMapping
Flux<Point> list() {
return this.pointRepository.findAll();
}
}
Swagger配置：
import com.google.common.base.Predicate;
import com.google.common.base.Predicates;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import springfox.documentation.builders.ApiInfoBuilder;
import springfox.documentation.builders.ParameterBuilder;
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.service.Contact;
import springfox.documentation.service.Parameter;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;
import java.util.ArrayList;
import java.util.List;
@Configuration
@EnableSwagger2
public class TrackServiceSwaggerConfig {
@Bean
public Docket api() {
ParameterBuilder aParameterBuilder = new ParameterBuilder();
// aParameterBuilder.name("Authorization").modelRef(new ModelRef("string")).parameterType("header").required(true).build();
List<Parameter> header = new ArrayList<Parameter>();
header.add(aParameterBuilder.build());
return new Docket(DocumentationType.SWAGGER_2)
.apiInfo(apiInfo())
.select()
.apis(RequestHandlerSelectors.any())
.paths(paths())
.build()
.globalOperationParameters(header);
}
// Describe your apis
private ApiInfo apiInfo() {
return new ApiInfoBuilder()
.title("Track-Service APIs")
.description("description goes here ")
.contact(new Contact("Nodirbek Sadullayev", "n0d1r.uz", "n.sadullayev@gmail.com"))
.version("1.0-SNAPSHOT")
.build();
}
// Only select apis that matches the given Predicates.
private Predicate<String> paths() {
// Match all paths except /error
return Predicates.and(
PathSelectors.regex("/.*"),
Predicates.not(PathSelectors.regex("/error.*"))
);
}
}

有什么建议 ？谢谢！
解决方法:
Swagger 3即将发布,它包括对netty的支持.
到那时,您可以使用快照版本：
{
repositories {
maven {
url 'http://oss.jfrog.org/artifactory/oss-snapshot-local/'
}
}
dependencies {
compile 'io.springfox:springfox-swagger2:3.0.0-SNAPSHOT'
compile 'io.springfox:springfox-swagger-ui:3.0.0-SNAPSHOT'
compile 'io.springfox:springfox-spring-webflux:3.0.0-SNAPSHOT'
}
}
然后使用@ EnableSwagger2WebFlux启用它
