新增书籍页面：

修改书籍页面：

BookController类：

package com.lyr.controller;

import com.lyr.pojo.Books;
import com.lyr.service.BookService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

import java.util.List;

@Controller
@RequestMapping("/book")
public class BookController {
    //controller调service层
    @Autowired
    @Qualifier("BookServiceImpl")
    private BookService bookService;

    //查询全部书籍，并跳转到书籍展示页面
    @RequestMapping("/allBooks")
    public String list(Model model){
        List<Books> list = bookService.queryAllBooks();
        model.addAttribute("list",list);
        return "allBooks";
    }

    //添加书籍页面
    @RequestMapping("/toAddBooks")
    public String toAddBook(){
        return "toAddBooks";
    }

    //添加书籍
    @RequestMapping("/addBooks")
    public String addBook(Books books){
        bookService.addBook(books);
        return "redirect:/book/allBooks";
    }

    //修改书籍信息页面
    @RequestMapping("/toUpdateBook")
    private String toChangeBook(int id,Model model){
        Books books = bookService.queryBook(id);
        model.addAttribute("Qbooks",books);
        return "toUpdateBook";
    }

    //修改书籍信息
    @RequestMapping("/updateBook")
    private String updateBook(Books books){
        System.out.println(books);
        bookService.updateBook(books);
        return "redirect:/book/allBooks";
    }

    //删除书籍
    @RequestMapping("/deleteBook")
    public String deleteBook(int id){
        bookService.deleteBook(id);
        return "redirect:/book/allBooks";
    }

    //查询书籍
    @RequestMapping("/queryBooks")
    public String queryBooks(String queryBookName,Model model){
        List<Books> books = bookService.queryBooksByName(queryBookName);
        model.addAttribute("list",books);
        return "allBooks";
    }
}

index.jsp显示主页面：

      h4 {
        width: 150px;
        height: 25px;
        margin: 50px auto;
        background: pink;
        text-align: center;
        border-radius: 4px;
      }
