Framework Error

What This Error Means

This error is caused when Spring Boot is unable to register a bean due to it not implementing a valid ServiceLoader interface or being a known configuration class.

Why It Happens

This error occurs when Spring Boot is scanning for beans in the application context and encounters a bean that doesn't meet the required criteria. It can happen when there's a misconfigured bean or when a bean is not properly annotated.

How to Fix It

1. 1To fix this error, ensure that the bean you're trying to register implements one of the valid ServiceLoader interfaces or is annotated as a configuration class. You can also try to use the @Lazy annotation on the bean to delay its registration.

Example Code Solution

deepSecurityConfig public class SecurityConfig extends WebSecurityConfigurerAdapter {
    // ... configuration code ...
