1.在BooksController控制器中根據索引添加容器
public class BooksController extends Controller {
//for all books
public Result index(){
Set<Book> books = Book.allBooks();
return ok(index.render(books)) ;
} }
2.在views中創建名爲books的包，並在包中創建名爲index的Play 2Template,其內容爲：
@(books:Set[Book])
<html>
<head>
<title>All Books</title>
</head>
<body>
<h1>All Books</h1>
@for(book <- books){
<a href="#">@book.title</a>
<P>price : @book.price</P>
<p>author: @book.author</p>
}
</body>
</html>
3.在控制器中引包：
import views.html.books.*;
