Consider defining a bean of type 'com.example.manage.service.BookService' in your configuration.

This message is usually an error message that occurs during Spring Boot application startup. It means that Spring Boot is unable to find a configuration for a bean of type `com.example.manage.service.BookService`.
To solve this issue, you can define a configuration for the bean in one of your Spring Boot configuration files, such as `application.properties` or `application.yml`. For example, if you have a class `BookService` that you want to define as a bean, you can add the following line to your configuration file:
```
spring.bean.name=bookService
```
This will tell Spring Boot to create a new instance of the `BookService` class and register it as a bean with the name `bookService`.
Alternatively, you can annotate the `BookService` class with the `@Service` annotation, which tells Spring Boot to automatically create and register an instance of the class as a bean. For example:
```
@Service
public class BookService {
// ...
}
```
I hope this helps! Let me know if you have any other questions.
