我正在嘗試直接在 Spring Boot 的控制器類中將 commandlinerunner 接口實現為 lambda 表達式，作為其功能接口。這本來應該作為第一件事運行，但它沒有。如果我創建一個單獨的類并添加注釋，這會很有效@Component。..import org.springframework.boot.CommandLineRunner;@RestController@RequestMapping("/api/v1")public class BookController {@Autowiredprivate BookRepository bookRepository;public BookController(BookRepository bookRepository) { this.bookRepository = bookRepository;}CommandLineRunner obj = (String... args) -> { Book entity1 = new Book("How to stay focused", "Miriyam Bali"); Book entity2 = new Book("Turn the World", "Cliyo Mathew"); Book entity3 = new Book("New Heights", "Arsana Jyesh"); Book entity4 = new Book("Create into leaves", "Nicholas A Buzaz"); List<Book> books = Arrays.asList(entity1, entity2, entity3, entity4); this.bookRepository.saveAll(books); };

你可以通過這個來實現這一點。它會起作用的。

import org.springframework.boot.CommandLineRunner;
@RestController
@RequestMapping("/api/v1")
public class BookController {
@Autowired
private BookRepository bookRepository;
public BookController(BookRepository bookRepository) {
this.bookRepository = bookRepository;
}
@Bean
public CommandLineRunner run() throws Exception {
return args -> {
Book entity1 = new Book("How to stay focused", "Miriyam Bali");
Book entity2 = new Book("Turn the World", "Cliyo Mathew");
Book entity3 = new Book("New Heights", "Arsana Jyesh");
Book entity4 = new Book("Create into leaves", "Nicholas A Buzaz");
List<Book> books = Arrays.asList(entity1, entity2, entity3, entity4);
this.bookRepository.saveAll(books);
};
}
