我有以下配置
@Configuration
@EnableWebFlux
public class WebfluxConfig {
@Bean
RouterFunction<?> routerFunction(UserResource userResource) {
return route(GET("/user"), r -> ok()
.body(userResource.findAll(), UserDto.class));
}
}
当我启动应用程序时,它会产生预期的映射

然而,当我尝试连接到它时,我得到了404.并且路由器谓词没有被调用过一次。

我在这里做错了什么?
答案 0 :(得分:1)
看来你正在使用Spring Boot,值得在你的问题中指出这一点(或相应地标记它)。
看起来你正在使用Spring MVC(或者至少将Spring MVC作为传递依赖);首先,如果您希望使用Spring WebFlux,则应删除该依赖项。
此外,由于您正在使用Spring Boot,因此您不应添加@EnableWebFlux
,因为它表示您希望完全控制WebFlux配置并手动执行Spring Boot。

项目中的RouterFunction
也无法正常工作。然后,我删除了spring-boot-starter-web
依赖性,它正在起作用。
依赖关系如下:
dependencies {
// add starter-web & starter-webflux at same time,RouterFunction is not working
// implementation 'org.springframework.boot:spring-boot-starter-web'
implementation 'org.springframework.boot:spring-boot-starter-webflux'
compileOnly 'org.projectlombok:lombok'
testImplementation 'org.springframework.boot:spring-boot-starter-test'
testImplementation 'io.projectreactor:reactor-test'
}
答案 2 :(得分:1)
从starter-tomcat
中排除starter-web
依赖性,spring boot将自动使用Netty服务器,该服务器是starter-webflux
的一部分。
