项目学习《第二天》

今天上午决定先分析每个包下面的类的作用及类中的方法的作用。（主要是这个代码的注释太少了！！

controller

UserController

DashboardController

DeliveryController

ItemCategoryController

ItemController

OrderController

ReItemController

ShippingController

StockManage

controller层分析结束
欠缺的知识：分页显示、导出excel还有一些功能实现的细节
决定删除及修改的：上传图片的功能先删除吧，以及统一一下类名

aspect

WebLogAspect

只学了log4j记录日志，自己写的时候看看可不可以改成用log4j记录日志
通过使用AOP的方式计算并打印各种方法的耗时日志，有利于后续的代码优化

filter

SQLInjectionFilterSevlet

这里是作者提到的一个优化，没明白，到时候再进一步研究
通过拦截器实现反SQL注入，防止用户输入SQL敏感字符串

mapper

配置版mabatis我感觉很麻烦，我会换成注解版的。

缓存和工具等用到了再拿出来分析

接下来先把实体类写了以及配置文件。

配置文件application.yml

spring:

  #database
  datasource:
    url: jdbc:mysql://127.0.0.1:3306/sjx?useUnicode=true&characterEncoding=UTF-8
    username: root
    password: root
    driver-class-name: com.mysql.jdbc.Driver

  #thymeleaf
  thymeleaf:
    prefix: classpath:/templates/
    mode: HTML5
    encoding: UTF-8
    content-type: text/html
    cache: false #开发时关闭缓存,不然没法看到实时页面
    suffix: .html

  #http
  http:
    multipart:
      max-file-size: 10Mb
      max-request-size: 100Mb

  #mail
  mail:
    host: smtp.exmail.qq.com
    username: [email protected]
    password: test
    from: [email protected]


#druid

  port: 6379
  timeout: 10
  pollMaxTotal: 1000
  pollMaxIdle: 500
  poolMaxWait: 500

#mybatis 先配置出来 到时候看用不用
#mybatis:
#  config-location: classpath:/mybatis-config.xml
#  mapper-locations: classpath:/mapper/*Mapper.xml

    private int mOrderRefund; //月退单
    private String mOrderRefundper; //月退单环比
    private int pv; //访问量

以上写完了配置文件以及实体类。

接下来把login页面功能看懂自己写一遍。

首先是登录功能：

mapper接口存放sql语句

/*user表SQL语句*/
@Mapper
@Repository
public interface UserMapper {

    @Select("select * from tb_user where userName=#{userName} and password=#{password} and state=1")
    User selectByNameAndPwd(User user);

    @Insert("insert into tb_user(id,userName,password,realName,business,email,headPicture,addDate,updateDate,state) values (null,#{userName},#{password},null,null,#{email},null,#{addDate},#{updateDate},1)")

    int insert(User user);

    @Update("update tb_user set password=#{password},email=#{email},realName=#{realName},business=#{business},updateDate=#{updateDate} where userName=#{userName}")
    int update(User user);

    @Select("select 1 from tb_user where userName=#{userName}")
    int selectIsName(User user);

    @Select("select password from tb_user where userName=#{userName} and email=#{email}")
    String selectPwdByName(User user);

}

UserService接口存放user业务操作

/*user业务操作*/
public interface UserService {
    
    User selectByNameAndPwd(User user);

    int insert(User user);

    int update(User user);

    int selectIsName(User user);

    String selectPwdByName(User user);
}

UserServiceImpl类实现user表接口具体业务逻辑

/*user表接口具体业务逻辑*/
@Service
public class UserServiceImpl implements UserService {

    @Autowired
    UserMapper userMapper;

    /*查询用户密码*/
    @Override
    public User selectByNameAndPwd(User user) {
        return userMapper.selectByNameAndPwd(user);
    }

    /*添加用户*/
    @Override
    public int insert(User user) {
        return userMapper.insert(user);
    }

    /*更新用户*/
    @Override
    public int update(User user) {
        return userMapper.update(user);
    }

    /*通过用户名查询*/
    @Override
    public int selectIsName(User user) {
        return userMapper.selectIsName(user);
    }

    /*通过用户名和邮箱查询密码*/
    @Override
    public String selectPwdByName(User user) {
        return userMapper.selectPwdByName(user);
    }
}

**UserController类

登录功能实现

/*用户管理*/
@Controller
public class UserController {

    @Autowired
    UserService userService;

    @Autowired
    HttpSession httpSession;

    /*跳转登录界面*/
    @GetMapping("user/login")
    public String loginGet(Model model){
        return "login";
    }

    /*验证登录*/
    @PostMapping("user/login")
    public String loginPost(User user, Model model){
        User user1 = userService.selectByNameAndPwd(user);
        if(user1 != null){
            httpSession.setAttribute("user",user1);
            User name = (User) httpSession.getAttribute("user");
            return "redirect:dashboard";
        }else {
            model.addAttribute("error","账号或密码错误");
            return "login";
        }
    }

}

看完源代码然后自己写的，写完之后当然有问题修改再写，最后再在空白文档手敲一遍主要功能

login.html

<body class="gray-bg">
	<div class="middle-box text-center loginscreen animated fadeInDown">
		<div>
			<div>
				<h2 class="logo-name">YX</h2>
			</div>
			<h3>欢迎进入后台管理系统</h3>
			<!--<p>Login in. To see it in action.</p>-->
			<form class="m-t" role="form" action="login" method="post">
				<div class="form-group">
					<input type="text" class="form-control" placeholder="输入账号" name="userName" required="" />
				</div>
				<div class="form-group">
					<input type="password" class="form-control" placeholder="输入密码" name="password" required="" />
				</div>
				<button type="submit" class="btn btn-primary block full-width m-b">登  录</button>
				<a th:href="@{forget}" href="#"><small>忘记密码 ?</small></a>
				<!--<a th:href="@{register}" href="#"><small>没有账号 ?</small></a>-->
				<p class="text-muted text-center">
					<small>没有账号 ?</small>
				</p>
				<a class="btn btn-sm btn-white btn-block" th:href="@{register}" href="register.html">注  册</a>
			</form>
		</div>
	</div>

	<script th:inline="javascript">
		var error = [[${error}]];
		$(document).ready(function () {
			if(error!=null){
				 swal({
		         	title : "温馨提示",
		         	text : error
		      	});
			}
		});

	</script>
</body>

页面展示

注册功能实现

    /*跳转注册页面*/
    @GetMapping("user/register")
    public String registerGet(Model model){
        return "register";
    }

    /*注册*/
    @PostMapping("user/register")
    public String registerPost(User user, Model model){
        System.out.println("用户名：" + user.getUserName());
        try{
            userService.selectIsName(user);
            model.addAttribute("error", "该用户已存在");
        }catch (Exception e){
            Date date = new Date();
            user.setAddDate(date);
            user.setUpdateDate(date);
            userService.insert(user);
            System.out.println("注册成功");
            model.addAttribute("error", "注册成功");
            return "login";
        }
        return "register";
    }

完成解决一些问题然后再写的，一遍ok。

注册功能遇到两个问题注册功能遇到两个问题

1.跳转注册页面跳转不过来

一开始作者没写后面的th:action，login界面也没写，其实我比较好奇怎么跳转成功的。这个页面就跳转不成功，于是我加了后面的th:action，解决。
2.insert查询语句一直报错！！这个语句太长了！！写的时候一定要注意检查啊！！！我前后看的眼睛都要瞎了，陆续发现少了括号、单词拼错、少写列名等等问题……以至于花的时间有点久，以后一点多加注意！！

今天的学习就到这里啦！现在是十一点，第一天的是昨晚忘记发表了，所以今天早上发表的。今天依旧收获满满啦明天要再努力呀～
