服务名称：SimpleBookService

定义服务类（Server.java）

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
@Path("/books")
public class SimpleBookService {
    @GET
    @Produces("application/json") // Produce JSON content
    public BookList getBooks() {
        // Simulate book data retrieval from a database or external API
        BookList bookList = new BookList();
        bookList.add(new Book("Book1", "Author1")));
        bookList.add(new Book("Book2", "Author2")));
        return bookList;
    }
}

定义客户端类（Client.java）

import javax.ws.rs.client.ClientBuilder;
import javax.ws.rs.core.Response;
public class SimpleBookClient {
    private static final String BASE_URL = "http://localhost:8080/books/";
    public static void main(String[] args) {
        // Create a client instance using ClientBuilder
        Client client = ClientBuilder.newClient();
        // Call the RESTful API to get book list
        Response response = client.target(BASE_URL).request().get();
        if (response.getStatus() == 200) {
            System.out.println("Book List:");
            SimpleBookService.BookList bookList = response.readEntity(SimpleBookService.BookList.class));
            for (Book book : bookList.getBooks()) {
                System.out.println("- " + book.getName() + " by " + book.getAuthor()));
            }
        } else {
            System.out.println("Failed to get book list. Response status: " + response.getStatus());
        }
        // Close the client
        client.close();
    }
}
