If I add @Constructorbinding to the class, the compiler will tell me an error. I remember in Spring Boot 2.2.x After version, @Constructorbinding can be used instead of setter
package com.example.demo;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.boot.context.properties.ConstructorBinding;
import org.springframework.stereotype.Component;
/**

@Component
@ConfigurationProperties(prefix = "mail")
public class ConfigProperties {
private String hostName;
private int port;
private String from;
public ConfigProperties(String hostName, int port, String from) {
this.hostName = hostName;
this.port = port;
this.from = from;
}
public ConfigProperties() {
}
public String getHostName() {
return hostName;
}
public void setHostName(String hostName) {
this.hostName = hostName;
}
public int getPort() {
return port;
}
public void setPort(int port) {
this.port = port;
}
public String getFrom() {
return from;
}
public void setFrom(String from) {
this.from = from;
}
}

I read this #23216 #23172 #23607 , but I still don't quite understand it

As described in the release notes, it's no longer needed and should be removed.
