載入一些測試資料

package com.mcf7.spring.domain;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.CommandLineRunner;
import org.springframework.stereotype.Component;

@Component
public class DatabaseLoader implements CommandLineRunner {
    private final BookRepository repository;

    @Autowired
    public DatabaseLoader(BookRepository repository) {
        this.repository = repository;
    }

    public void run(String... Strings) throws Exception {
        Book book1 = new Book();
        book1.setIsbn("6515616168418510");
        book1.setTitle("SuperAwesomeTitle");
        book1.setAuthor("MCF7");
        book1.setDescription("This Book is super epic!");
        repository.save(book1);
    }
}

只是在理想情況下載入一些測試資料，這應該僅在開發配置檔案下新增。
