今日内容
一、 AdminLTE
1.AdminLTE介绍
AdminLTE是一款建立在bootstrap和jquery之上的开源的模板主题工具，它提供了一系列响应的、
可重复使用的组件，并内置了多个模板页面；同时自适应多种屏幕分辨率，兼容PC和移动端。通
过AdminLTE，我们可以快速的创建一个响应式的Html5网站。AdminLTE框架在网页架构与设计
上，有很大的辅助作用，尤其是前端架构设计师，用好AdminLTE 不但美观，而且可以免去写很大
CSS与JS的工作量。
AdminLTE依赖于两个框架Bootstrap3与JQuery1.11+。
2.AdminLTE基本使用介绍
布局：
.wrapper包住了body下的所有代码
.main-header里是网站的logo和导航栏的代码
.main-sidebar里是用户面板和侧边栏菜单的代码
.content-wrapper里是页面的页面和内容区域的代码
.main-footer里是页脚的代码
.control-sidebar里是页面右侧侧边栏区域的代码
布局选项：
fixed：固定
layout-boxed：盒子布局
layout-top-nav：顶部隐藏
sidebar-collapse：侧边栏隐藏
sidebar-mini：侧边栏隐藏时有小图标
皮肤：
skin-blue：蓝色
skin-black：黑色
skin-purple：紫色
skin-yellow：黄色
skin-red：红色
skin-green：绿色

二、SSM整合案例的基本介绍
1.SSM综合练习功能介绍
主要讲解Maven工程搭建，以及基于MySQL数据库的商品表信息，并完成SSM整合。
1. 商品查询
基于SSM整合基础上完成商品查询，要掌握主面页面main.jsp及商品显示页面product-list.jsp页面的创建。
2. 商品添加
进一步巩固SSM整合，并完成商品添加功能，要注意事务操作以及product-add.jsp页面生成。
3. 订单查询
订单的查询操作，它主要完成简单的多表查询操作，查询订单时，需要查询出与订单关联的其它表中信息，要了解订单及其它表关联关系。
4. 订单分页查询
订单分页查询，使用的是mybatis分页插件PageHelper，要掌握PageHelper的基本使用。
5. 订单详情查询
订单详情是用于查询某一个订单的信息。
6. Spring Security 概述
Spring Security是 Spring 项目组中用来提供安全认证服务的框架，要掌握spring Security框架的配置及基本的认证与授权操作。
7. 用户管理
用户管理中掌握基于spring Security的用户登录、退出操作。以及用户查询、添加、详情有等操作，这些功能
的练习是对前期SSM知识点的进一步巩固。
8. 角色管理
角色管理主要完成角色查询、角色添加。
9. 资源权限管理
资源权限管理主要完成查询、添加操作，它的操作与角色管理类似，角色管理以及资源权限管理都是对权限管理的
补充。
10. 权限关联与控制
主要会讲解用户角色关联、角色权限关联，这两个操作是为了后续完成授权操作的基础，关于授权操作会在服务器端及页面端分别完成。
11. AOP日志处理
AOP日志处理，使用spring AOP切面来完成系统级别的日志收集。
2.SSM综合练习表结构介绍
1. 产品表：
2. 订单表：旅客表与订单表多对多关系
3. 会员表：
4. 旅客表：
5. 用户表：角色表和用户表多对多关系
6. 角色表：资源权限表和角色表多对多关系
7. 资源权限表：
8. 日志表：
三、产品操作
1.数据库与表结构介绍
1. 如果id采用int类型：
CREATE DATABASE erm; -- 创建企业权限管理数据库
USE erm; -- 使用企业权限管理数据库
CREATE TABLE product(
id INT PRIMARY KEY AUTO_INCREMENT, -- 无意义，主键
productNum VARCHAR(50) NOT NULL UNIQUE, -- 产品编号，唯一且不为空
productName VARCHAR(50), -- 产品名称（路线名称）
cityName VARCHAR(50), -- 出发城市
departureTime TIMESTAMP, -- 出发时间
productPrice DOUBLE(11,2), -- 产品价格
productDesc VARCHAR(500), -- 产品描述
productStatus INT -- 产品状态（0：关闭，1：开启）
);
INSERT INTO PRODUCT VALUES (NULL , 'product001', '德州三日游', '德州', '20220529143800', 1000, '家乡的路线', 0);
INSERT INTO PRODUCT VALUES (NULL , 'product002', '济南三日游', '济南', '20220530130000', 2000, '成长的地方', 0);
INSERT INTO PRODUCT VALUES (NULL , 'product003', '淄博三日游', '淄博', '20220429113200', 1800, '留恋的城市', 1);
INSERT INTO PRODUCT VALUES (NULL , 'product004', '北京三日游', '北京', '20220610090800', 2500, '不错的旅行', 1);
2. 如果id采用varchar类型：
CREATE DATABASE ssm;
USE ssm;
CREATE TABLE product(
id VARCHAR(32) PRIMARY KEY,
productNum VARCHAR(50) NOT NULL UNIQUE,
productName VARCHAR(50),
cityName VARCHAR(50),
departureTime TIMESTAMP,
productPrice DOUBLE,
productDesc VARCHAR(500),
productStatus INT
);
INSERT INTO PRODUCT
VALUES (id , 'itcast-001', '北京三日游', '北京', '20220529143800', 1200, '不错的旅行', 1);
-------------------------------------------------------------------------------------------
DELIMITER $$
CREATE
/*[DEFINER = { user | CURRENT_USER }]*/
TRIGGER `ssm`.`id_test` BEFORE INSERT -- 触发器名称
ON `ssm`.`product` -- 触发器被触发的时机
FOR EACH ROW BEGIN -- 触发器所作用的表名称
SET new.id=REPLACE(UUID(),'-',''); -- 触发器执行的逻辑
END$$
DELIMITER ;
2.SSM环境搭建
1.创建项目：myprj_erm
2. 创建模块：以myprj_erm_dao举例，需要创建dao、service、domain、utils子模块
3. 创建模块：web模块需要使用骨架

3.产品操作-查询全部产品1
1. 创建controller：
package cn.fsm.myprj.erm.controller;
import cn.fsm.myprj.domain.Product;
import cn.fsm.myprj.service.IProductService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
import java.util.List;
@Controller
@RequestMapping("/product")
public class ProductController {
@Autowired
private IProductService productService;
@RequestMapping("/findAll.do")
public ModelAndView findAll() throws Exception {
ModelAndView modelAndView = new ModelAndView();
List<Product> productList = productService.findAll();
modelAndView.addObject("", productList);
modelAndView.setViewName("");
return modelAndView;
}
}
2. 导入IProductService依赖和配置tomcat7插件：

4.产品操作-查询全部产品2
1. 创建pages文件夹：将product-list.jsp存入pages文件夹中
2. 修改index.jsp页面：
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<html>
<body>
<a href="${pageContext.request.contextPath}/product/findAll.do">查询所有的产品信息</a>
</body>
</html>
3. 将页面资源复制到webapp目录下：
5.产品操作-查询全部产品3
1. 根据product-list.jsp页面循环遍历的数组名称：
package cn.fsm.myprj.erm.controller;
import cn.fsm.myprj.domain.Product;
import cn.fsm.myprj.service.IProductService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
import java.util.List;
@Controller
@RequestMapping("/product")
public class ProductController {
@Autowired
private IProductService productService;
@RequestMapping("/findAll.do")
public ModelAndView findAll() throws Exception {
ModelAndView modelAndView = new ModelAndView();
List<Product> productList = productService.findAll();
modelAndView.addObject("productList", productList);
modelAndView.setViewName("product-list");
return modelAndView;
}
}
2. 添加product-list.jsp头部、导航侧栏的文件到pages文件夹：
3. idea配置运行：
4. 解决所有产品信息列表不显示产品状态、日期（含转换）：
package cn.fsm.erm.utils;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;
public class DateUtils {
/**
* 日期转换成字符串
* @param targetDate 目标日期
* @param formatString 格式字符串
* @return
*/
public static String dateToString(Date targetDate, String formatString) {
SimpleDateFormat simpleDateFormat = new SimpleDateFormat(formatString);
return simpleDateFormat.format(targetDate);
}
/**
* 字符串转换成日期
* @param targetString 目标字符串
* @param formatString 格式字符串
* @return
* @throws ParseException
*/
public static Date stringToDate(String targetString, String formatString) throws ParseException {
SimpleDateFormat simpleDateFormat = new SimpleDateFormat(formatString);
return simpleDateFormat.parse(targetString);
}
}
package cn.fsm.erm.domain;
import cn.fsm.erm.utils.DateUtils;
import java.util.Date;
public class Product {
private int id; //主键
private String productNum; //编号 唯一
private String productName; //名称
private String cityName; //出发城市
private Date departureTime; //出发时间
private String departureTimeStr;
private double productPrice; //产品价格
private String productDesc; //产品描述
private Integer productStatus; //状态 0关闭 1开启
private String productStatusStr;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getProductNum() {
return productNum;
}
public void setProductNum(String productNum) {
this.productNum = productNum;
}
public String getProductName() {
return productName;
}
public void setProductName(String productName) {
this.productName = productName;
}
public String getCityName() {
return cityName;
}
public void setCityName(String cityName) {
this.cityName = cityName;
}
public Date getDepartureTime() {
return departureTime;
}
public void setDepartureTime(Date departureTime) {
this.departureTime = departureTime;
}
public String getDepartureTimeStr() {
if (departureTime != null) {
departureTimeStr = DateUtils.dateToString(departureTime, "yyyy-MM-dd HH:mm:ss");
}
return departureTimeStr;
}
public void setDepartureTimeStr(String departureTimeStr) {
this.departureTimeStr = departureTimeStr;
}
public double getProductPrice() {
return productPrice;
}
public void setProductPrice(double productPrice) {
this.productPrice = productPrice;
}
public String getProductDesc() {
return productDesc;
}
public void setProductDesc(String productDesc) {
this.productDesc = productDesc;
}
public Integer getProductStatus() {
return productStatus;
}
public void setProductStatus(Integer productStatus) {
this.productStatus = productStatus;
}
public String getProductStatusStr() {
if(productStatus != null) {
if (productStatus == 0 ) {
productStatusStr = "关闭";
} else if (productStatus == 1) {
productStatusStr = "开启";
}
}
return productStatusStr;
}
public void setProductStatusStr(String productStatusStr) {
this.productStatusStr = productStatusStr;
}
}
页面效果：
6.main.jsp页面制作
1. 首页导入：
2. 修改首页跳转：
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<html>
<body>
<%--<a href="${pageContext.request.contextPath}/product/findAll.do">查询所有的产品信息</a>--%>
<jsp:forward page="/pages/main.jsp"></jsp:forward>
</body>
</html>
页面展示：
7.产品操作-添加产品流程描述
8.产品操作-产品添加操作1
1. 新增product-add.jsp页面：
2. 修改product-list.jsp页面：新增新建跳转到product-add.jsp页面
3. 开始编写添加产品操作流程：

}
}

void save(Product product);
}
