春天反应REST服务返回ServerResponse对象

我有问题试图返回ServerResponse对象来回活性休息服务春天反应REST服务返回ServerResponse对象

@RequestMapping(path = "/", method = RequestMethod.GET) 
    public Mono<ServerResponse> getPages(@RequestParam(value = "siteId", required = false) String siteId, 
      @RequestParam(value = "parentId", required = false) String parentId) throws Exception { 

     Flux<MyModel> result = pageModelService.getMyModels(Id, name); 

     return ServerResponse.ok().body(result, MyModel.class).switchIfEmpty(ServerResponse.notFound().build()); 
    }

我越来越

javax.servlet.ServletException：组织.springframework.web.util.NestedServletException：请求处理失败;嵌套的例外是 java.lang.IllegalArgumentException异常：未找到返回值类型的转换：类 org.springframework.web.reactive.function.server.DefaultEntityResponseBuilder $ DefaultEntityResponse

，这里是我的pom.xml

我试图添加杰克逊的依赖，但似乎这是另一个问题

任何想法会受到欢迎

难道您发布MyModel.java？你有所有领域的获得者/安装者吗？ –

MyModel.java是一个简单的2字符串属性，我使用的是lombok，并且安装程序和Getter无处不在此外，如果我返回Flux 它工作正常 – Seb

@Seb您能否提供您的'pom.xml'文件？ – ledniov

默认情况下，spring-boot-starter-webflux将使用Reactor Netty作为webflux运行时。

如果您想要使用Jetty作为目标运行时，只需排除spring-boot-starter-reactory-netty,spring-boot-starter-webflux依赖关系并明确添加spring-boot-starter-jetty。

然后，只需将Spring引导声明为父POM。

<parent> 
    <groupId>org.springframework.boot</groupId> 
    <artifactId>spring-boot-starter-parent</artifactId> 
    <version>2.0.0.M3</version> 
    <relativePath/> <!-- lookup parent from repository --> 
</parent>

清理其他未使用的依赖项，删除您的dependencyManagement。

检查我的工作示例（但我使用的是默认堆的Netty为运行时）：
