spring java-17 eclipse dependency-injection Java

I've been researching this but I'm relatively new to this, so bear with me. Hey everyone, I'm running into an issue that's driving me crazy... I'm working on a project and hit a roadblock. After upgrading my project to Java 17 in Eclipse 2023-09, I'm working with issues with Spring not being able to resolve certain bean dependencies... Specifically, I'm getting the following behavior when I run my application: ``` Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.example.service.MyService' available ``` I have ensured that my `@ComponentScan` is correctly set up to include the package where `MyService` is defined. Here's a snippet of my main application class: ```java @SpringBootApplication @ComponentScan(basePackages = "com.example") public class MyApplication { public static void main(String[] args) { SpringApplication.run(MyApplication.class, args); } } ``` Additionally, I have a service class defined as follows: ```java @Service public class MyService { public void performAction() { // action implementation } } ``` I've also checked the build path and ensured that the Spring dependencies are correctly resolved in Maven. The `pom.xml` includes the Spring Boot dependencies: ```xml <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> ``` I tried cleaning and rebuilding the project multiple times, but the scenario continues. Additionally, I have checked the Eclipse preferences for Java Compiler compliance and made sure it is set to 17. Is there something specific to Java 17 that I might be missing in the configuration? Any help would be greatly appreciated. Am I missing something obvious? I'm working on a application that needs to handle this. Is there a better approach? This is part of a larger service I'm building. How would you solve this? I'm coming from a different tech stack and learning Java. What's the correct way to implement this? Any pointers in the right direction? Thanks for taking the time to read this!
