Question

我将在Spring Boot中使用redis-active。但是，所有现有代码都是在webmvc模式下工作的代码。尝试对webmvc使用redis-active而不是使用webflux是否有问题？从Servlet 3.1开始，即使不使用webflux，它似乎也可以异步工作。

这是示例代码。请让我指出是否有我不熟悉的异步开发方法。如果您将active-redis与webmvc结合使用而不是webflux，请让我知道问题出在哪里。

弹簧依赖性

compile('org.springframework.boot:spring-boot-starter-data-redis-reactive')
compile("org.springframework.boot:spring-boot-starter-web")

示例代码

@RestController
public class CoffeeController {
    private final ReactiveRedisOperations<String, Coffee> coffeeOps;
    private final ReactiveRedisConnectionFactory factory;

    WebClient client = WebClient.create();

    public CoffeeController(ReactiveRedisConnectionFactory factory, ReactiveRedisOperations<String, Coffee> coffeeOps) {
        this.factory = factory;
        this.coffeeOps = coffeeOps;
    }

    @GetMapping("/coffees")
    public Flux<Coffee> all() {
return coffeeOps.keys("*")
                .flatMap(coffeeOps.opsForValue()::get);
    }


}

是否可以使用spring-boot-starter-web实现redis反应功能？
