Hot Deployment of User‑Implemented Interfaces in Java: Annotation and Reflection Approaches

This article demonstrates how to define a simple Java interface, provide two implementation styles (Spring‑annotation and pure‑reflection), package the implementation as a JAR, and dynamically load, register, replace, or remove the implementation at runtime using URLClassLoader and Spring's bean factory.

Hot Deployment of Custom Java Interface Implementations Using Reflection and Spring

This article demonstrates how to design a simple Calculator interface, provide two implementation strategies (annotation‑based Spring beans and reflection‑based classes), and dynamically load, register, and unload user‑supplied JAR files at runtime through hot‑deployment mechanisms in a Java backend system.

Hot Deployment of Java Interface Implementations Using Jar Packages with Spring and Reflection

This article demonstrates how to design a simple Calculator interface, provide two implementation strategies (Spring annotation and reflection), and achieve hot deployment by uploading JAR files, dynamically loading classes, registering or removing beans in the Spring container, and testing the runtime behavior.
