# 二、数据库设计

### （1）数据库创建

```sql
-- 创建员工表
create table admin(
id int primary key auto_increment,
username varchar(20) not null,
password varchar(20) not null
)
-- 添加管理员数据
insert into admin values(null,'王恒杰','123456');
insert into admin values(null,'杨福君','whj63135');
insert into admin values(null,'邓正武','675437');
-- 查询管理员
select *from admin;

-- 创建水果表
create table fruit(
id int primary key auto_increment,
image varchar(30) not null,
name varchar(20) not null,
price double not null,
month int not null,
createTime date
);
-- 查询水果表
select * from fruit;
-- 添加水果信息
insert into fruit values(null,'/img.jpg','苹果','5.00',5,NOW());
```

# 四、管理员核心功能

### 1、前端

```html
<%@page isELIgnored="false" contentType="text/html; harset=utf-8" pageEncoding="UTF-8" %>

    </div>
    <div class="row" style="margin-top: 20px;">
        <div class="col-sm-8 col-sm-offset-2">
            <div id="content">
                <form method="post" action="${pageContext.request.contextPath}/admin/login">
                    <div class="form-group">
                        <label for="username">用户名</label>

                    </tr>
                    <input type="submit" style="width: 98%" class="btn btn-danger" value="登录&raquo;"/>
                </form>
            </div>
            ${requestScope.msg}
        </div>
    </div>
    <div class="row" style="margin-top: 40px;">
        <div class="col-sm-8 col-sm-offset-2">
            <h5 class="text-center">Fruit@136.com</h5>
        </div>
    </div>
</div>
</body>
</html>

```

### 2、控制层

```java
package com.tjcu.controller;

import com.tjcu.entity.Admin;
import com.tjcu.service.AdminService;
import com.tjcu.utils.VerifyCodeUtils;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

import javax.servlet.ServletOutputStream;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;
import java.io.IOException;

import static javax.swing.text.html.CSS.getAttribute;

/**
 * @author 王恒杰
 * @date 2021/11/28 16:22
 * @Description:
 */
@Controller
@RequestMapping("admin")
public class AdminAction {
    @Autowired
    private AdminService adminService;
    @RequestMapping("login")
    public String login(Admin admin, HttpServletRequest request,String adminCode){
        //1.比较验证是否一致
        HttpSession session = request.getSession();
        String code = session.getAttribute("code").toString();
        if(code.equals(adminCode)){
            Admin login = adminService.login(admin.getUsername(), admin.getPassword());
           if(login!=null){
               request.setAttribute("admin",login);
               session.setAttribute("admin",login);
               return "forward:/fruit/showAll?pageNumber=1";
           }else {
               request.setAttribute("msg","用户名或者密码输入错误");
               return "login";
           }
        }else {
            request.setAttribute("msg","验证码输入错误");
            return "login";
        }

}

/**
     * 用来生成验证码方法
     */
    @RequestMapping("generateImageCode")
    public void generateImageCode(HttpSession session, HttpServletResponse response) throws IOException {
        //1.生成随机字符串
        String code = VerifyCodeUtils.generateVerifyCode(4);
        //2.保存随机字符串到Session中
        session.setAttribute("code",code);
        //3.将随机字符串生成图片
        //4.通过response响应图片
        response.setContentType("image/png");//指定响应类型
        ServletOutputStream os = response.getOutputStream();
        VerifyCodeUtils.outputImage(80,30,os,code);
    }
@RequestMapping("cancel")
    public String cancel(HttpServletRequest request){
        request.getSession().invalidate();
        request.setAttribute("msg","管理员已经退出登录！");
        return "login";
    }
}

```

# 五、水果相关功能核心代码

### 1、全选jquery实现

```java
<script>
    $("#selectAll").click(function () {
        //:checkbox 获取当前选中的单选按钮或者复选框
        //:checkbox:gt(0) 获取当前复选框大于0的复选框
        //prop修改标签的属性 标签对象.prop(“属性名”,”属性值”);
        //prop获取标签的属性 标签对象.prop(“属性名”);
        //checked:选中
        //注意：在单选框和复选框中checked只要出现checked就是选中，不管他是否等于true还是false
        $(":checkbox:gt(0)").prop("checked",$("#selectAll").prop("checked"))
    })

```

### 2、确认删除jquery实现

```java
<%--单个删除--%>
<script>
        function delRow(id,pageNumber){
            if(window.confirm("你确定删除这个商品吗？")){
                location.href="${pageContext.request.contextPath}/fruit/drop?pageNumber="+pageNumber+"&id="+id;
            }
        }
</script>
```

### 3、修改和数据回显前端页面

```html
<%@page isELIgnored="false" contentType="text/html; harset=utf-8" pageEncoding="UTF-8" %>
<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
\
<%@taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %>
<html>
<head>
    <title>update</title>
    <link rel="stylesheet" type="text/css" href="${pageContext.request.contextPath}/css/bootstrap.min.css"/>
</head>
<body>
<div id="wrap">
    <div id="top_content" class="row" style="margin: 0 auto;">
        <div class="col-sm-8 col-sm-offset-2">
            <div id="header">
                <div id="topheader">
                    <h1 class="text-center text-info">欢迎进入水果管理系统V1.0</h1>
                </div>
                <div id="navigation">
                </div>
            </div>
        </div>
    </div>
    <div class="row" style="margin-top: 20px;">
        <div class="col-sm-8 col-sm-offset-2">
            <div id="content">
                <p id="whereami">
                </p>
                <h1>
                    修改水果信息:
                </h1>
                <form action="${pageContext.request.contextPath}/fruit/update" method="post" enctype="multipart/form-data">
                    <input  type="hidden" name="id" value="${requestScope.fruit.id}">
                    <div class="form-group">
                        <label for="name">名称</label>
                        <input type="text" class="form-control" name="name" id="name" value="${requestScope.fruit.name}"
                               placeholder="输入水果名称">
                    </div>
                    <div class="form-group">
                        <label for="price">价格</label>
                        <input type="text" class="form-control" name="price" id="price"
                               value="${requestScope.fruit.price}" placeholder="输入水果价格">
                    </div>
                    <div class="form-group">
                        <label for="age">保质期(单位:月)</label>
                        <input type="text" class="form-control"  id="age" name="month"
                               value="${requestScope.fruit.month}" placeholder="输入水果保质期">
                    </div>
                    <div class="form-group">
                        <label for="photos">水果图片</label>
                        <input type="file" ref="file" id="photos" class="form-control" name="photo"/>
                    </div>
                    <input type="submit"  style="width: 98%" class="btn btn-warning" value="确认修改" />
                </form>

</div>
        </div>
    </div>
    <div id="footer">
        <div class="row" style="margin-top: 40px;">
            <div class="col-sm-8 col-sm-offset-2">
                <h5 class="text-center">Fruit@136.com</h5>
            </div>
        </div>
    </div>
</div>
</body>
</html>

```

### 4、分页前端页面实现

```java
     <%--colspan:跨列数--%>
                        <td colspan="7" align="center">
                            <c:if test="${requestScope.pageNumber>1}">
                                <a href="${pageContext.request.contextPath}/fruit/showAll?pageNumber=${requestScope.pageNumber-1}">上一页</a>
                            </c:if>
                            <c:if test="${requestScope.pageNumber<=1}">
                                上一页
                            </c:if>
                            <%--当前页数--%>
                            <c:forEach begin="1" end="${requestScope.totalPage}" var="page">
                                <a href="${pageContext.request.contextPath}/fruit/showAll?pageNumber=${page}">${page}</a>
                            </c:forEach>
                            <%--下一页数--%>
                            <c:if test="${requestScope.pageNumber<requestScope.totalPage}">
                                <a href="${pageContext.request.contextPath}/fruit/showAll?pageNumber=${requestScope.pageNumber+1}">下一页</a>
                            </c:if>
                            <c:if test="${requestScope.pageNumber>=requestScope.totalPage}">
                                下一页
                            </c:if>
                        </td>
                    </tr>
```

### 5、Controller层

```java

@Controller
@RequestMapping("fruit")
public class FruitAction {
