SSM 环境搭建与产品操作
1.数据库与表结构介绍
PLSQL Developer 13 是一个集成开发环境，专门面向Oracle数据库存储程序单元的开发PL/SQL Developer侧重于易用性、代码品质和生产力 。
连接数据库的配置
解决中文？？乱码
在maven bin目录下运行以下命令：
mvn install:install-file -DgroupId=com.oracle -DartifactId=ojdbc14 -Dversion=10.2.0.1.0 -Dpackaging=jar -Dfile=D:\mnt\ojdbc14-10.2.0.1.0.jar以上地址信息部分，请根据本地jar包的信息自行修改。
创建用户与授权
数据库我们使用Oracle
-- 用户名 ssm08 -- 登录密码 itheima
-- Create the user create user SSM08 identified by itheima; -- Grant/Revoke role privileges grant connect to SSM08; grant resource to SSM08;
产品表信息描述
CREATE TABLE product( id varchar2(32) default SYS_GUID() PRIMARY KEY, productNum VARCHAR2(50) NOT NULL, productName VARCHAR2(50), cityName VARCHAR2(50), DepartureTime timestamp, productPrice Number, productDesc VARCHAR2(500), productStatus INT, CONSTRAINT product UNIQUE (id, productNum) ) insert into PRODUCT (id, productnum, productname, cityname, departuretime, productprice,productdesc, productstatus) values ('676C5BD1D35E429A8C2E114939C5685A', 'itcast-002', '北京三日游', '北京', to_timestamp('10-10-2018 10:10:00.000000', 'dd-mm-yyyy hh24:mi:ss.ff'), 1200, '不错的旅行', 1); insert into PRODUCT (id, productnum, productname, cityname, departuretime, productprice,productdesc, productstatus) values ('12B7ABF2A4C544568B0A7C69F36BF8B7', 'itcast-003', '上海五日游', '上海', to_timestamp('25-04-2018 14:30:00.000000', 'dd-mm-yyyy hh24:mi:ss.ff'), 1800, '魔都我来了', 0); insert into PRODUCT (id, productnum, productname, cityname, departuretime, productprice,productdesc, productstatus) values ('9F71F01CB448476DAFB309AA6DF9497F', 'itcast-001', '北京三日游', '北京', to_timestamp('10-10-2018 10:10:00.000000', 'dd-mm-yyyy hh24:mi:ss.ff'), 1200, '不错的旅行', 1);
2.SSM环境搭建maven工程
使用Maven管理项目，创建parent工程和子模块。
解决maven项目创建archetype过慢的问题:

1.3在domain编写实体类
package cn.bjut.ssm.domain; import java.util.Date; /** * 商品信息 */ public class Product { private String 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; //方便网页展示，数据库里没有对应字段 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; //方便网页展示，数据库里没有对应字段
实体类的pom.xml添加对后面步骤编写的工具类的依赖坐标
<dependencies> <dependency> <groupId>cn.bjutgroupId> <artifactId>heima_ssm_utilsartifactId> <version>1.0-SNAPSHOTversion> dependency> dependencies>
选择子模块heima_ssm_dao ，在它的pom.xml里引入兄弟模块的依赖坐标。
<dependencies> <dependency> <groupId>cn.bjutgroupId> <artifactId>heima_ssm_domainartifactId> <version>1.0-SNAPSHOTversion> dependency> dependencies>
新建两个package在java&resources目录下
cn.bjut.ssm.dao
新建一个接口，IProductDao
package cn.bjut.ssm.dao; import cn.bjut.ssm.domain.Product; import java.util.List; public interface IProductDao { //查询所有的产品信息 public ListfindAll() throws Exception; }
选择子模块heima_ssm_service ，在它的pom.xml里引入兄弟模块(dao层)的依赖坐标。
<dependencies> <dependency> <groupId>cn.bjutgroupId> <artifactId>heima_ssm_daoartifactId> <version>1.0-SNAPSHOTversion> dependency> dependencies>
在java目录下新建一个package ,在里面新建一个实现类的包impl
cn.bjut.ssm.service
编写接口 IProductService
package cn.bjut.ssm.service; import cn.bjut.ssm.domain.Product; import java.util.List; public interface IProductService { //查询所有的产品信息 public ListfindAll() throws Exception; }
编写接口的实现类 ProductServiceImpl
@Service @Transactional //注解的方式配置spring事务管理 public class ProductServiceImpl implements IProductService { @Autowired private IProductDao productDao; @Override public ListfindAll()throws Exception{ return productDao.findAll(); } }
1.SSM环境搭建与产品操作.pdf 里面是用mybatis的注解方式查询操作数据库，现在我选择用.xml配置文件的方式使用mybatis
MyBatis从入门到精通(第3章)： MyBatis注解方式的基本使用
MyBatis从入门到精通(第2章)：MyBatis XML方式的基本用法
在 heima_ssm_dao 子模块的resources目录下，新建一个cn.bjut.ssm.dao包（package），然后在其中新建一个文件：
IProductDao.xml 【如果是mybatis整合spring框架，这里的.xml配置文件的文件名必须和与之对应接口的文件名完全一致！】
xml version="1.0" encoding="UTF-8" ?>
DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd" >
namespace属性的值为：接口的全限定类名。resultType是实体类的全限定类名。【测试后发现整合spring框架并且分父子工程依赖模块，resultType就必须写全限定类名】数据库的字段名放前面，实体类的成员变量名放后面。
xml version="1.0" encoding="UTF-8" ?>
DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd" >
<mapper namespace="cn.bjut.ssm.dao.IProductDao">
<select id="findAll()" resultType="cn.bjut.ssm.domain.Product">
select id,
productNum productNum,
productName productName,
cityName cityName,
DepartureTime DepartureTime,
productPrice productPrice,
productDesc productDesc,
productStatus productStatus
from product
select>
mapper>
下面将引入框架用到的各种配置文件

最后开始编写web子模块的controller类：
ProductController
package cn.bjut.ssm.controller; import cn.bjut.ssm.service.IProductService; import cn.bjut.ssm.domain.Product; 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; //产品添加 // @RequestMapping("/save.do") // public String save(Product product) throws Exception { // productService.save(product); // return "redirect:findAll.do"; // } //查询全部产品 @RequestMapping("/findAll.do") public ModelAndView findAll() throws Exception { ModelAndView mv = new ModelAndView(); Listps = productService.findAll(); mv.addObject("productList", ps); mv.setViewName("product-list1"); return mv; } }
回到heima_ssm_utils这个子模块下，新建一个工具类。
cn.bjut.ssm.utils.DateUtils
package cn.bjut.ssm.utils; import java.text.ParseException; // import java.text.SimpleDateFormat; import java.util.Date; public class DateUtils { //日期转换成字符串 public static String date2String(Date date, String patt) { SimpleDateFormat sdf = new SimpleDateFormat(patt); String format = sdf.format(date); return format; } //字符串转换成日期 public static Date string2Date(String str, String patt) throws ParseException { SimpleDateFormat sdf = new SimpleDateFormat(patt); Date parse = sdf.parse(str); return parse; } }
heima_ssm_web的pom.xml里面可以添加一个Tomcat7的插件。

使用IDEA并且指定Tomcat7插件测试运行的 网页访问路径如下

6.产品操作-查询全部产品3
根据.jsp页面的需要，重新编辑cn.bjut.ssm.domain
Product.java
package cn.bjut.ssm.domain; import cn.bjut.ssm.utils.DateUtils; import org.springframework.format.annotation.DateTimeFormat; import java.util.Date; /** * 商品信息 */ public class Product { private String id; // 主键 private String productNum; // 编号 唯一 private String productName; // 名称 private String cityName; // 出发城市 @DateTimeFormat(pattern="yyyy-MM-dd HH:mm") private Date departureTime; // 出发时间 private String departureTimeStr; //为了页面显示，数据库里没有的字段 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; //为了页面显示，数据库里没有的字段 public String getDepartureTimeStr() { if(departureTime!=null){ departureTimeStr= DateUtils.date2String(departureTime,"yyyy-MM-dd HH:mm:ss"); } return departureTimeStr; } public void setDepartureTimeStr(String departureTimeStr) { this.departureTimeStr = departureTimeStr; } public String getProductStatusStr() { if (productStatus != null) { // 状态 0 关闭 1 开启 if(productStatus==0) productStatusStr="关闭"; if(productStatus==1) productStatusStr="开启"; } return productStatusStr; } public void setProductStatusStr(String productStatusStr) { this.productStatusStr = productStatusStr; } //===============================================================================// public String getId() { return id; } public void setId(String 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 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; } //========================================================================================// }
HTTP Status 500 - Request processing failed; nested exception is org.apache.ibatis.binding.BindingException: Invalid bound statement (not found)
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> <property name="configLocation" value="classpath:mybatis/SqlMapConfig.xml" /> <property name="mapperLocations" value="classpath:cn/bjut/ssm/dao/*.xml"/> bean> <bean id="mapperScanner" class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="cn.bjut.ssm.dao"/> bean>此时测试SSM项目会提示报错，理由是找不到findall()方法。因为讲师用的是注解开发mybatis ,而我这里是用：接口类+.xml配置文件的方式。
前面在给oracle数据库创建users ssm08时候，没有指定tablespace,会导致后面没有权限查到数据表。ITHEIMA是DBA权限创建PRODUCT表时所在的表空间。
-- alter user username default tablespace userspace alter user ssm08 default tablespace ITHEIMA;
查询全部产品的
ProductController
@Controller @RequestMapping("/product") public class ProductController { @Autowired private IProductService productService; //查询全部产品 @RequestMapping("/findAll.do") public ModelAndView findAll() throws Exception { ModelAndView mv = new ModelAndView(); Listps = productService.findAll(); mv.addObject("productList", ps); mv.setViewName("product-list"); return mv; } }
7.product-list.jsp页面制作
使用IDEA处理JSP页面的脚本内容，替换的快捷键是 Ctrl+R
Except Comments可以排除注释的内容。
../
被替换为
${pageContext.request.contextPath}
如果使用MySQL做数据库，那么语句语法是有不同的要注意。
use itheima; drop table if exists `product`; -- 创建1个表 CREATE TABLE `product`( `id` varchar(32) NOT NULL, `productNum` varchar(50) NOT NULL, `productName` varchar(50), `cityName` varchar(50), `departureTime` timestamp, `productPrice` INT, `productDesc` varchar(500), `productStatus` INT, PRIMARY KEY (`id`) ); -- 插入测试数据 insert into product (id, productNum, productName, cityName, departureTime, productPrice,productDesc, productStatus) values ('676C5BD1D35E429A8C2E114939C5685A', 'itcast-002', '北京三日游', '北京', '2018-10-10 10:10:00', 1200, '不错的旅行', 1); insert into product (id, productNum, productName, cityName, departureTime, productPrice,productDesc, productStatus) values ('9F71F01CB448476DAFB309AA6DF9497F', 'itcast-001', '北京三日游', '北京', '2018-10-10 10:10:00', 1200, '不错的旅行', 1); insert into product (id, productNum, productName, cityName, departureTime, productPrice,productDesc, productStatus) values ('12B7ABF2A4C544568B0A7C69F36BF8B7', 'itcast-003', '上海五日游', '上海', '2019-10-10 14:30:00', 1800, '魔都我来了', 0);
db.properties
jdbc.driver=com.mysql.cj.jdbc.Driver jdbc.url=jdbc:mysql://localhost:3306/itheima?serverTimezone=Asia/Shanghai jdbc.username=root jdbc.password=root
8.main.jsp页面制作
当前项目默认的index.jsp长得比较简陋，我们希望从index.jsp直接跳转到视觉效果更好的 main.jsp 前端页面。
注释掉超链接
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <html> <head> <title>主页title> head> <body> <%--<a href="${pageContext.request.contextPath}/product/findAll.do">查询所有的产品信息a>--%> <jsp:forward page="WEB-INF/pages/main.jsp">jsp:forward> body> html>
图片资源加载不成功，最后把images目录移动到webapp目录下。
<div class="content-wrapper">
<%--资源相对路径--%>
<img src="${pageContext.request.contextPath}/images/center.jpg"
width="100%" height="100%" />
div>
9.产品操作-添加产品流程描述
10.产品操作-产品添加操作
添加产品用资料里给的product-add.jsp页面文件，我把它重命名为product-add2.jsp放到webapp/page/目录下。
在WEB-INF/pages/product-list2.jsp页面的“新建”按钮处添加一个onclick属性，写入浏览器直接跳转文件资源路径。
控制类方法的添加
ProductController
@Controller @RequestMapping("/product") public class ProductController { @Autowired private IProductService productService; //查询全部产品 @RequestMapping("/findAll.do") public ModelAndView findAll() throws Exception { ModelAndView mv = new ModelAndView(); Listps = productService.findAll(); mv.addObject("productList", ps); mv.setViewName("product-list2"); return mv; } //产品添加后跳转查询产品 @RequestMapping("/save.do") public String save(Product product)throws Exception{ productService.save(product); return "redirect:findall.do"; } }
Service层
ProductServiceImpl
@Service @Transactional //注解的方式配置spring事务管理 public class ProductServiceImpl implements IProductService { @Autowired private IProductDao productDao; @Override public ListfindAll()throws Exception{ return productDao.findAll(); } //服务层保存添加产品调用了DAO层对象的方法 @Override public void save (Product product){ productDao.save(product); } }
DAO层接口的@Insert注解插入数据
public interface IProductDao { //查询所有的产品信息 @Select("select * from product") public ListfindAll() throws Exception; // https://www.cnblogs.com/MarlonKang/p/11491217.html @Insert({"insert into product(productNum,productName,cityName,departureTime,productPrice,productDesc,productStatus)", "values(#{productNum},#{productName},#{cityName},#{departureTime},#{productPrice},#{productDesc},#{productStatus})"}) public void save(Product product); }
SQL语句不在一行会报错，所以在每一行都用一对 英文双引号，然后在外侧添加一对{ } ，第一行SQL末尾有一个英文，
//在springMVC框架下的实体类的Date类型的成员变量上使用 //可以实现页面表单提交字符串数据转化成Date类型JAVA数据 @DateTimeFormat(pattern = "yyyy-MM-dd HH:mm")
拓展练习： 删除按钮，通过网页上的 checkbox选中的实现。
-- 查询PRODUCT表中数据 select * from product t;
-- 删除PRODUCT表中数据通过productNum值 delete from PRODUCT where PRODUCTNUM = '1234567890';
使用PL/SQL Developer再Commit一下，提交事务。
现在我们需要在product-list.jsp这个用来展示查询所有产品信息的网页上，添加删除按钮的功能实现。首先要解决的是，那一组自动产生的checkbox的value值的获取和选中状态的判断。这里使用了jQurey技术。
参考教程： checkbox 复选框全选代码
Jquery 数组操作
<c:forEach var="product" items="${productList}" varStatus="s" > <tr> <td><input type="checkbox" value="${product.id}" name="Ids" id ="${s.index}" >td> <td>${product.id}td> <td>${product.productNum} td> <td>${product.productName}td> <td>${product.cityName}td> <td>${product.departureTimeStr}td> <td class="text-center">${product.productPrice}td> <td class="text-center">${product.productDesc}td> <td class="text-center">${product.productStatusStr}td> <td class="text-center"> <button type="button" class="btn bg-olive btn-xs">订单button> <button type="button" class="btn bg-olive btn-xs">详情button> <button type="button" class="btn bg-olive btn-xs">编辑button> td> tr> c:forEach>
工具栏那部分按钮代码如下。
<button type="button" class="btn btn-default" title="新建" onclick="location.href='../page/product-add2.jsp'"><i class="fa fa-file-o">i> 新建button> <button type="button" class="btn btn-default" title="删除" onclick="deleteProduct()"><i class="fa fa-trash-o">i> 删除button>
测试jQuery获取checkbox数组对象,并提取数组元素checkbox的value值。
<script> function deleteProduct() { var arrayObj =document.getElementsByName("Ids"); //s.index从0开始，所以第一行的checkbox的id=0 var checkbox =document.getElementById("0"); //第一弹出的是checkbox的总行数 alert(arrayObj.length); //第二弹出的是第一行的产品ID值 alert(checkbox.value); //获取数组的元素，通过数组索引 //数组索引值为显示的checkbox行数减一 var testGetArrValue=arrayObj[1]; //第三弹出整个checkbox数组中被索引的第2个元素的value值 alert(testGetArrValue.value); var selectList = []; alert(selectList.length); //第四弹出数组初始长度0 $('input[name=Ids]:checked ').each(function () { //这里用所选复选框或运算后的值 //jQuery数组的push方法 selectList.push($(this).val()); }); alert(selectList.length); //第五弹出选中的checkbox个数 } script>
现在的需求是：如何把JSP页面里的字符串数组-->后台的数组变量。
\02 JavaWeb+黑马旅游网\javaweb\2-15Jquery\第1节 JQuery基础\04_JQuery对象和JS对象区别与转换.mp4
服务器端无法直接使用浏览器客户端内容，必须先提交到服务器才行，用表单或者ajax来提交var变量。
\02 JavaWeb+黑马旅游网\javaweb\2-16Ajax和JSON\第2节 JQuery方式实现Ajax
通过ajax提交数组时，后端spring MVC中的@RequestParam获取不到参数。ajax请求时增加：traditional: true 就可以正常提交了。
关于Ajax请求传递数组参数的解决办法
product-list2.jsp
Web层的Controler控制类的method
//删除产品的某个分类通过产品ID编号 @RequestMapping("/delete.do") public String deleteByNum(@RequestBody ListselectList )throws Exception{ System.out.println( "JSP页面通过AJAX技术提交POST请求的路径找到。" ); System.out.println( selectList ); //从List中遍历字符串完成删除操作 for (String productId :selectList ) { System.out.println( productId ); productService.deleteByNum(productId); } System.out.println( "JSP页面通过AJAX技术提交字符串数组成功实现。" ); return"redirect:findAll.do"; }
DAO层接口
package cn.bjut.ssm.dao; import cn.bjut.ssm.domain.Product; import org.apache.ibatis.annotations.Delete; import org.apache.ibatis.annotations.Insert; import org.apache.ibatis.annotations.Select; import java.util.List; public interface IProductDao { //查询所有的产品信息 @Select("select * from product") public ListfindAll() throws Exception; // https://www.cnblogs.com/MarlonKang/p/11491217.html @Insert({"insert into product(productNum,productName,cityName,departureTime,productPrice,productDesc,productStatus)", "values(#{productNum},#{productName},#{cityName},#{departureTime},#{productPrice},#{productDesc},#{productStatus})"}) public void save(Product product); //删除产品通过产品的ID属性值,oracle数据库的TABLE列的别名字段不区分大小写。 @Delete("delete from PRODUCT where ID = #{id}") public void deleteByNum(String id); }
经过测试，实现了通过浏览器页面上的“删除”按钮+checkbox 来删除oracle数据库的产品表中的信息。
