[Solved] Consider this bean definition:@Bean @ConditionalOnProperty(name = "service.... }Why does the bean never get created even when service.enabled=true is set in application.properties? | Spring Boot

Spring Boot - Advanced Patterns

Consider this bean definition:

@Bean
@ConditionalOnProperty(name = "service.enabled", havingValue = "true")
public Service service() {
    return new Service();
}

Why does the bean never get created even when service.enabled=true is set in application.properties?

AThe property key name is incorrect or misspelled

BThe property is a string but havingValue expects a boolean

CThe bean method is missing @Component annotation

DThe bean method must be static to work with @ConditionalOnProperty

Step-by-Step Solution

Solution:

Step 1: Verify property key spelling
If the property key in application.properties is misspelled or different, condition fails.
Step 2: Check other options
HavingValue compares strings, so boolean type mismatch is not an issue; @Component is not needed on @Bean methods; static is not required.
Final Answer:
The property key name is incorrect or misspelled -> Option A
Quick Check:
Property key must match exactly [OK]

Quick Trick: Check property key spelling carefully for conditional beans [OK]
