我的数据库中有一个包含多行的列表，但查询只返回1行，而不是更多行。
我想按标题查找我的书，但例如，当我有多本书的标题中有相同的单词时，我想显示这两本书，但查询没有返回它。

• • HTML页面**

<form action="#" th:action="@{/searchbook(param=${book?.getBookTitle()})}" th:object="${book}" >        
    <label for="title">Find Book by Title</label>
    <input type="text" id="title" name="title" th:value="${book?.getBookTitle()}" placeholder="Book Title"/>
    <input type="submit" value="Search"/>

    <table id="table1">

          <tr>
             <th>ID</th>
             <th>Title</th>
             <th>Author</th>
             <th>Copies</th>
          </tr>

          <tr th:each="re:${book}" id="tr1">
               <td th:text="${book?.getId()}">id</td>
               <td th:text="${book?.getBookTitle()}" id="ln">title</td>

               <td th:text="${book.getBookCopies()}">copies</td>
           </tr>
    </table>

         <!--    <a th:href="@{/update(idNumber=${reader?.idNumber},firstname=${reader?.firstname})}" th:field="*{firstname}">Update</a>
             <a th:href="@{/delete(idNumber=${reader?.idNumber})}" th:value="${reader?.idNumber}">Delete</a>
        -->
</form>

• • 图书管理员**

@GetMapping({"/searchbook","/searchbook{title}"})
public String searchBookByTitle(@RequestParam("title") Optional<String> title, Model model){

    if(title.isPresent()) {
         List<Book> bookList = bookService.findBookByTitle(title.get());
         for(Book book1:bookList) {
              model.addAttribute("book", book1);
         }
         return "book/searchbook";
    }
    else
    {
         return "book/searchbook";
    }
}

• • 书库**

@Repository
public interface BookRepository extends CrudRepository<Book,Long> {

    @Query(value = "SELECT * FROM BOOK where book_title like %:bookTitle%",nativeQuery = true)
    List<Book> findBooksByBookTitle(String bookTitle);
}

• • 预订服务实现**

@Override
public List<Book> findBookByTitle(String title) {
    List<Book> books = new ArrayList<>();
    bookRepository.findBooksByBookTitle(title)
                  .forEach(books::add);
    for(Book book:books)
                System.out.println(book);
    return books;
}

• • 控制台日志**

    Book{id=3, bookTitle='Amintiri de altadata', bookAuthor='Vasea Mure', bookCopies=1}

在控制台中，我看到3行与搜索的单词，但在我的网页上，我只看到1行。我猜有什么问题，我的控制器，与model.addAttribute ...
可能是什么原因呢？
