1 环境搭建

2 显示所有书籍

2.1 编写主页 index.jsp

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
  <head>
    <title>$Title$</title>
    <style>
      a{
        text-decoration: none;
        color: #000;
        font-size: 18px;
      }
      h3{
        width: 180px;
        height: 38px;
        margin: 100px auto;
        text-align: center;
        line-height: 38px;
        background: deepskyblue;
        border-radius: 10px;
      }
    </style>
  </head>
  <body>
  <h3>
    <a href="${pageContext.request.contextPath}/book/allBook">进入书籍页面</a>
  </h3>
  </body>
</html>

2.2 在控制层新建一个类BookController并添加查询全部书籍的方法

package com.lv.controller;

import com.lv.pojo.Books;
import com.lv.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层调service层
    @Autowired
    @Qualifier("BookServiceImpl")
    private BookService bookService;
    @RequestMapping("/allBook")
    //查询全部的书籍,并且返回到一个书籍展示页面
    public String list(Model model){
        List<Books> list = bookService.queryAllBook();
        model.addAttribute("list",list);
        return "allBook";
    }
}

2.3 编写一个展示书籍列表的页面 allBook.jsp

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>书籍展示</title>
    <%--BootStrap美化界面--%>
    <link href="https://cdn.staticfile.org/twitter-bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet">
</head>
<body>

                <h1>
                    <small>书籍列表----显示所有书籍</small>
                </h1>
            </div>
        </div>
    </div>
    <div class="row">
        <div class="col-md-4 column">
            <%--toAddBook--%>
            <a class="btn btn-primary" href="${pageContext.request.contextPath}/book/toAddBook">新增书籍</a>
            <%--查询书籍--%>
            <form action="${pageContext.request.contextPath}/book/queryBook" method="post" style="float: right" class="form-inline">
                <input type="text" name="queryBookName" class="form-control" placeholder="请输入要查询的书籍名称">

            </form>
        </div>
    </div>
    <div class="row chearfix">
        <div class="row clearfix">
            <table class="table table-hover table-striped">
                <thead>
                    <tr>

                </thead>
                <%--书籍从数据库中查询出来,从这个list中遍历出来:foreach--%>
                <tbody>
                    <c:forEach var="book" items="${list}">
                        <tr>
                            <td>${book.bookID}</td>
                            <td>${book.bookName}</td>
                            <td>${book.bookCounts}</td>
                            <td>${book.detail}</td>
                            <td>

                                <a href="${pageContext.request.contextPath}/book/deleteBook/${book.bookID}">删除</a>
                            </td>
                        </tr>
                    </c:forEach>
                </tbody>
