2.项目功能
3.项目搭建步骤
1)新建Maven工程
2)修改目录,修改pom.xml文件
3)添加SSM框架的所有依赖
4)拷贝jdbc.porperties到resources目录下
5)新建applicationContext_dao.xml文件,进行数据访问层的配置
6)新建applicationContext_service.xml文件,进行业务逻辑层的配置
7)新建springmvc.xml文件,配置springmvc的框架
8)新建SqlMapConfig.xml文件,进行分页插件的配置
9)对web.xml文件进行配置
10)使用逆向工程生成pojo和mapper的文件
11)开发业务逻辑层,实现登录判断
12)开发控制器AdminAction,完成登录处理
13)改造页面,发送登录请求,验证登录

4.2 jdbc.properties
jdbc.driver=com.mysql.cj.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/xiaomissm?useSSL=false&serverTimezone=Asia/Shanghai&allowPublicKeyRetrieval=true
jdbc.username=数据库用户名
jdbc.password=数据库密码
4.3 Mybaties配置文件：SqlMapConfig.xml
Spring中整合了Mybaties中的大部分功能，因此mybaties配置文件中只配置了分页插件
DOCTYPE configuration
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">

4.4 Spring配置文件
整合了Mybaties，将Spring配置文件进了分层配置

5.逆向工程
用来快速生成pojo和mapper文件
1.配置文件
DOCTYPE generatorConfiguration

<generatorConfiguration>
<context id="testTables" targetRuntime="MyBatis3">

javaClientGenerator>
<table schema="" tableName="admin">table>
<table schema="" tableName="product_info">table>
<table schema="" tableName="product_type">table>

generatorConfiguration>
2.运行代码
package com.oracle.mybatis.tools;
import java.io.File;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;
import org.mybatis.generator.api.MyBatisGenerator;
import org.mybatis.generator.config.Configuration;
import org.mybatis.generator.config.xml.ConfigurationParser;
import org.mybatis.generator.exception.XMLParserException;
import org.mybatis.generator.internal.DefaultShellCallback;
public class GeneratorSqlmap {
public void generator() throws Exception{
List<String> warnings = new ArrayList<String>();
boolean overwrite = true;
//指定 逆向工程配置文件
File configFile = new File("generatorConfig.xml");
ConfigurationParser cp = new ConfigurationParser(warnings);
Configuration config = cp.parseConfiguration(configFile);
DefaultShellCallback callback = new DefaultShellCallback(overwrite);
MyBatisGenerator myBatisGenerator = new MyBatisGenerator(config,
callback, warnings);
myBatisGenerator.generate(null);
}
public static void main(String[] args) throws Exception {
try {
GeneratorSqlmap generatorSqlmap = new GeneratorSqlmap();
generatorSqlmap.generator();
} catch (Exception e) {
e.printStackTrace();
}
}
}
6.登录功能
6.1 MD5加密
package com.bjpowernode.utils;
import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;
public class MD5Util {
/**
* 1.MD5（message-digest algorithm 5）信息摘要算法，
* 它的长度一般是32位的16进制数字符串（如81dc9bdb52d04dc20036dbd8313ed055）
* 2.由于系统密码明文存储容易被黑客盗取
* 3.应用：注册时，将密码进行md5加密，存到数据库中，防止可以看到数据库数据的人恶意篡改。
* 登录时,将密码进行md5加密,与存储在数据库中加密过的密码进行比对
* 4.md5不可逆，即没有对应的算法，从产生的md5值逆向得到原始数据。
* 但是可以使用暴力破解，这里的破解并非把摘要还原成原始数据，如暴力枚举法。
*
*/
public final static String getMD5(String str){
try {
MessageDigest md = MessageDigest.getInstance("SHA");//创建具有指定算法名称的摘要
md.update(str.getBytes()); //使用指定的字节数组更新摘要
byte mdBytes[] = md.digest(); //进行哈希计算并返回一个字节数组
String hash = "";
for(int i= 0;i<mdBytes.length;i++){ //循环字节数组
int temp;
if(mdBytes[i]<0) //如果有小于0的字节,则转换为正数
temp =256+mdBytes[i];
else
temp=mdBytes[i];
if(temp<16)
hash+= "0";
hash+=Integer.toString(temp,16); //将字节转换为16进制后，转换为字符串
}
return hash;
} catch (NoSuchAlgorithmException e) {
e.printStackTrace();
}
return null;
}
}
6.2 业务层代码
package com.bjpowernode.service.impl;
import com.bjpowernode.mapper.AdminMapper;
import com.bjpowernode.pojo.Admin;
import com.bjpowernode.pojo.AdminExample;
import com.bjpowernode.service.AdminService;
import com.bjpowernode.utils.MD5Util;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import java.util.List;
/**
* @author zwghdu
* @create 2021-08-29-16:55
*/
@Service
public class AdminServiceImpl implements AdminService {
//在业务逻辑层中，一定给会有数据访问层的对象
@Autowired
AdminMapper adminMapper;
@Override
public Admin login(String name, String pwd) {
//根据传入的用户名到db中查询相应的用户对象
//如果有条件，则一定要创建AdminExample的对象，用来封装条件
AdminExample example = new AdminExample();
/**
* 如何添加条件
* select * from admin where a_name='admin'
*/
//添加用户名a_name条件
example.createCriteria().andANameEqualTo(name);
List<Admin> list = adminMapper.selectByExample(example);
//判断是否查到
if(list.size()>0){
Admin admin = list.get(0);
//如果查询到用户对象，再进行密码的比对,注意密码是密文
/**
* 分析：
* admin.getApass==>c984aed014aec7623a54f0591da07a85fd4b762d
* pwd==>000000
* 在进行密码对比时，要将传入的pwd进行MD5加密，再与数据库中查到的对象的密码进行对比
*/
String miPwd = MD5Util.getMD5(pwd);
if(miPwd.equals(admin.getaPass())){
return admin;
}
}
return null;
}
}
6.3 控制层代码
package com.bjpowernode.controller;
import com.bjpowernode.pojo.Admin;
import com.bjpowernode.service.AdminService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import javax.servlet.http.HttpServletRequest;
/**
* @author zwghdu
* @create 2021-08-29-17:17
*/
@Controller
@RequestMapping("/admin")
public class AdminAction {
//切记：在所有的界面层，一定会有业务逻辑层的对象
@Autowired
AdminService adminService;
//实现登录判断，并进行相应的跳转
@RequestMapping("/login")
public String login(String name, String pwd, HttpServletRequest request){
Admin admin = adminService.login(name,pwd);
if (admin != null){
//登录成功
request.setAttribute("admin",admin);
return "main";
}else {
//登录失败
request.setAttribute("errmsg","用户名或密码不正确！");
return "login";
}
}
}
