Validating Configuration Properties in Spring Boot Application Startup

1. 1Use the @ConfigurationProperties annotation to bind configuration parameters
2. 2Apply the @Validated annotation to enable validation
3. 3Configure validation constraints using annotations like @NotNull or @NotEmpty
4. 4Test the validation by running the application with invalid configuration properties
5. 5Use the Spring Boot validation API to handle validation errors

Developers and DevOps engineers can benefit from this knowledge to ensure smooth application startup and reduce errors
