Implementation questions about spring-redis-websocket

Thank you for your answer

In the class AsyncConfig, you used thread-pool of size 2, is it possible to use more?

Yes. You can assign more threads. The limit depends on the CPU/Memory and No. of concurrent requests you expect to handle. More Info at Spring Task Docs.

Why is Topic in ApplicationProperies and when does it get initialized? I assume that the method getChatMessage supposed to return "/topic/chat".

Topic is initiated by Spring Boot on boot-up when key-values are mapped from application.properties file. Its used for nested config. More Info at Spring Externaliz Config - Nested Properties.
I could have avoided the topic class by moving topic to prefix (i.e. raw.topic) since there is no other property in the root level.

So this Class can be re-written as:

import org.springframework.boot.context.properties.ConfigurationProperties;

@ConfigurationProperties(prefix = "raw.topic", ignoreUnknownFields = false)
public class ApplicationProperties {

    private String message;
    private String count;

    public String getCount() {
        return count;
    }

    public void setCount(String count) {
        this.count = count;
    }

    public String getMessage() {
        return message;
    }

    public void setMessage(String message) {
        this.message = message;
    }
}

Note: I have removed Topic class and moved its properties to outer class and updated prefix from raw to raw.topic.

I hope the above answers your questions. So I'm closing this.
