基于响应式内容在Spring Weblux ServerResponse上设置标题

基于响应式内容在Spring WebFlux ServerResponse上设置标题，可以通过使用ServerResponse类的header方法来设置响应头信息。具体步骤如下：

导入所需的依赖：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-webflux</artifactId>
</dependency>

创建一个处理请求的Handler类，例如MyHandler：

import org.springframework.http.MediaType;
import org.springframework.web.reactive.function.server.ServerRequest;
import org.springframework.web.reactive.function.server.ServerResponse;
import reactor.core.publisher.Mono;

public class MyHandler {
    public Mono<ServerResponse> handleRequest(ServerRequest request) {
        return ServerResponse.ok()
                .contentType(MediaType.TEXT_PLAIN)
                .header("Title", "My Title")
                .bodyValue("Hello, World!");
    }
}

创建一个处理请求的路由类，例如MyRouter：

import org.springframework.http.MediaType;
import org.springframework.web.reactive.function.server.RouterFunction;
import org.springframework.web.reactive.function.server.RouterFunctions;
import org.springframework.web.reactive.function.server.ServerResponse;
import static org.springframework.web.reactive.function.server.RequestPredicates.GET;
import static org.springframework.web.reactive.function.server.RequestPredicates.accept;

public class MyRouter {
    public RouterFunction<ServerResponse> route(MyHandler handler) {
        return RouterFunctions.route(GET("/hello").and(accept(MediaType.TEXT_PLAIN)), handler::handleRequest);
    }
}

创建一个启动类，例如Application：

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;

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

    @Bean
    public RouterFunction<ServerResponse> routerFunction(MyHandler handler) {
        MyRouter router = new MyRouter();
        return router.route(handler);
    }
}
