@EnableResourceServer不适用于spring-webflux

Question

我在http://start.spring.io创建了一个应用程序，指定了“ Reactive Web”和“ Security”。 然后，我构建并运行该应用程序而没有出现问题。

然后，将spring-security-oauth2-autoconfigure依赖项添加到pom中，并将@EnableResourceServer到我的应用程序类中。 我现在看到一个异常，因为即使我的应用程序不是基于servlet的，也正在寻找javax.servlet.Filter 。

我看到的例外是：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.security.oauth2.config.annotation.web.configuration.ResourceServerConfiguration': Post-processing of merged bean definition failed; nested exception is java.lang.TypeNotPresentException: Type javax.servlet.Filter not present

这是我的应用程序类：

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.security.oauth2.config.annotation.web.configuration.EnableResourceServer;

@SpringBootApplication
@EnableResourceServer
public class DemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }
}

Answer 1

spring-security-oauth2项目当前对Spring MVC和Servlet API有着严格的依赖性。 我不认为该项目已经支持Spring WebFlux。
