Spring Boot application not refreshing context after bean property update in Java 17

spring-boot java-17 beans Java

I'm relatively new to this, so bear with me. I'm experiencing an issue where changes to a bean property in my Spring Boot application are not being reflected in the application context unless I restart the server. I'm using Spring Boot 2.6.4 with Java 17 and have a configuration class that defines a bean with a mutable property. Here's a simplified version of my code: ```java import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; @Configuration public class MyConfig { @Bean public MyService myService() { return new MyService("initial value"); } } public class MyService { private String property; public MyService(String property) { this.property = property; } public String getProperty() { return property; } public void setProperty(String property) { this.property = property; } } ``` In one of my controllers, I have a method that updates this property: ```java import org.springframework.beans.factory.annotation.Autowired; import org.springframework.web.bind.annotation.PutMapping; import org.springframework.web.bind.annotation.RequestBody; import org.springframework.web.bind.annotation.RestController; @RestController public class MyController { @Autowired private MyService myService; @PutMapping("/updateProperty") public void updateProperty(@RequestBody String newValue) { myService.setProperty(newValue); } } ``` After making a PUT request to `/updateProperty` to change the property value, the changes are not reflected in the application context unless I restart the server. I have tried multiple ways to refresh the context: 1. Using `@RefreshScope` on my bean, but it doesn't seem to help in this case. 2. Attempting to call `ApplicationContext.refresh()` programmatically throws an exception as expected in a web application. I expected the bean to be updated dynamically after the PUT request. Instead, I'm still seeing the old value when I call `myService.getProperty()`. Is there a better way to handle this scenario in Spring Boot? Am I missing something fundamental about how Spring manages bean lifecycles? Any help would be greatly appreciated! For context: I'm using Java on Windows 10. Hoping someone can shed some light on this. What are your experiences with this?
