Spring 启动 webflux 无法解析 RestController

Question

我最近才开始使用 Spring-boot starter webflux 来尝试响应式 Web 堆栈，我运行正在解决项目中一个非常简单的 RestController 的问题。

这里是拼图的必要部分：

pom.xml

</project>

SampleController.java

package com.hello.sample.controller;

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class HelloController
{

    @GetMapping("/hello")
    public String hello()
    {
        return "Hello WebFlux";
    }
}

我在 application.properties

中设置了以下属性

server.port=8911
server.servlet.context-path=/sample-reactive

现在，当我运行应用程序作为 Spring 通过 Eclipse 启动应用程序并执行 curl 或 Postman 请求时，我得到一个 404 :。

查看控制台日志，我没有看到任何请求映射绑定到已定义的请求映射。

这是控制台日志 . ____ _ __ _ _

关于为什么会发生这种情况的任何想法，因为根据文档，我了解到即使使用 Webflux

也可以使用 @RestController 注释

Answer 1

Webflux 支持
