问题 I recently came back to a Spring project I'd been working on and I've run into issues when starting up the app. This question is probably a duplicate, but I haven't been able to find an answer.

问题 Our Project is using spring DI/IoC, so i am using autowiring to inject beans. The program needs to pass parameters to an object during it's instantiation. And the parameters are know at run time (not at compile time). How to achive this while using autowiring. Sample code is as below. Interface - IMessage package com.example.demo.services; public interface IMessage { String message(String name); } Implementations - SayHelloService package com.example.demo.services; import org.springframework
