spring boot 之登录笔记

     在测试平台的开发中，会牵涉到登录内容，页面需要登录后才能访问，所以，对于登录的开发是很有必要的。本文记录我在系统登录的一些自己的做法。

    首先对登录进行设计。

   如下：

    

   1.登录密码输入错误超过次数限制

  2.能够使用用户名密码登录，邮箱密码登录。

 目前登录所有信息都是在数据库存储。后续优化到redis里面。

  使用spring boot+ jpa+durid。数据库mysql。

 数据库设计如下：

DROP TABLE IF EXISTS `user`;
CREATE TABLE `user` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `username` varchar(64) NOT NULL COMMENT '用户名',
  `password` varchar(255) NOT NULL COMMENT '用户密码',
  `email` varchar(64) DEFAULT NULL COMMENT '用户邮箱',
  `status` int(11) NOT NULL DEFAULT '0' COMMENT '状态，1代表删除',
  `admin` int(11) NOT NULL DEFAULT '0' COMMENT '是否是管理员，1代表是管理员',
  `iphone` varchar(20) DEFAULT NULL COMMENT '用户手机号',
  `workid` int(11) NOT NULL DEFAULT '0',
  `token` varchar(255) DEFAULT NULL,
  `errornum` int(2) NOT NULL DEFAULT '0',
  `freeze` int(2) NOT NULL DEFAULT '0',
  `freezetime` datetime DEFAULT NULL,
  PRIMARY KEY (`id`,`username`),
  KEY `username` (`username`),
  KEY `email` (`email`)
) ENGINE=InnoDB AUTO_INCREMENT=76 DEFAULT CHARSET=utf8 COMMENT='用户表';

数据库名称为planone

 数据库创建后，我们去插入数据。

INSERT INTO `user` VALUES ('1', 'liwanlei', 'lueSGJZetyySpUndWjMBEg==', '952943386@qq.com', '0', '1', '', '1', 'liwanlei_vlywm4en9/IyTI64bLDQEA==', '0', '1', '2019-04-29 16:14:22');
那么接下来我们去创建工程
在pom文件增加依赖
<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-thymeleaf</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
          、  <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
 <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-freemarker</artifactId>
        </dependency>
<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-jpa</artifactId>
        </dependency>
        <dependency>
            <groupId>org.mybatis.spring.boot</groupId>
            <artifactId>mybatis-spring-boot-starter</artifactId>
            <version>1.2.0</version>
        </dependency>

            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
        </dependency>
<dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
        </dependency>
<dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>druid-spring-boot-starter</artifactId>
            <version>1.1.10</version>
        </dependency>
 <dependency>
            <groupId>org.thymeleaf</groupId>
            <artifactId>thymeleaf</artifactId>
        </dependency>
        <dependency>
            <groupId>org.thymeleaf</groupId>
            <artifactId>thymeleaf-spring4</artifactId>
            <version>2.1.6.RELEASE</version>
        </dependency>

添加依赖后同步更新。

在application.yaml 进行配置

spring:
  datasource:
    druid:
      driver-class-name: com.mysql.jdbc.Driver
      url:  jdbc:mysql://localhost:3306/planone?serverTimeZone=UTC&characterEncoding=utf8&useSSL=true
      username:  root
      password: 123456
      initial-size: 10
      max-active: 1000
      min-idle: 10
      max-wait: 60000
      time-between-eviction-runs-millis: 2000
      keep-alive: true
      filter:
        stat:
          slow-sql-millis: 10000
          log-slow-sql: true
      max-evictable-idle-time-millis: 900000
      min-evictable-idle-time-millis: 400000
    thymeleaf:
        cache: false
        suffix: .html
        mode: HTML5
        encoding: UTF-8
        prefix: classpath:/templates/
server:
  port: 9999

配置完毕后，我们在resoures 文件新建templates 文件 和static 文件，添加静态页面用。

那么我们接下来开发后台，首先写的是dao

@Data
@DynamicUpdate
@Entity
@JsonIgnoreProperties(value = {"hibernateLazyInitializer", "handler"})
public class User implements Serializable {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Integer id;
    private String username;
    private String password;
    private String email;
    private String iphone;
    private Integer status =0;
    private Integer admin =0;
    private String token;
    private Date freezetime;
    private  Integer errornum=0;
    private  Integer freeze= 0;
}

接下来去开发基于JpaRepository数据访问层

public interface UserRepository extends JpaRepository<User, Integer> {
    User findByUsername(String username);

    User findByEmail(String email);
}

　　开发server

public interface UserSerice {

    User login(String username, String password);

}

　　对应的实现类

@Service
@Component
public class UserSericeImpl implements UserSerice {
    @Autowired
    private UserRepository userRepository;
@Override
    public User login(String username, String password) {
        /*根据邮箱或者用户名登录*/
        User user = userRepository.findByUsername(username);
        if (user != null) {
            user = login_is(user, password, username);
            return user;
        } else {
            User useremail = userRepository.findByEmail(username);
            if (useremail != null) {
                user = login_is(useremail, password, username);
                return user;
            }
        }
        throw new PanExection(ResultEmus.USER_NOT_EXIT);
    }

  public User login_is(User user, String password, String username) {
        if (user.getStatus().equals(UserEmus.DELETE.getCode())) {
            throw new PanExection(ResultEmus.USER_DELETE);
        }
        SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
        try {
            try {
                if (user.getFreeze().equals(FreezeEmus.DELETE.getCode()) && (new Date().getTime() - format.parse(user.getFreezetime().toString()).getTime() < 6 * 60 * 1000)) {
                    user.setErrornum(0);
                    userRepository.saveAndFlush(user);
                    throw new PanExection(ResultEmus.USER_FREE);
                }
            } catch (ParseException e) {
                throw new PanExection(ResultEmus.EXCEPTIONS);
            }

        } catch (NullPointerException e) {
            userRepository.saveAndFlush(user);
        }
        Boolean b = null;
        try {
            b = MD5Until.checkoutpassword(password, user.getPassword());
        } catch (Exception e) {
            throw new PanExection(ResultEmus.EXCEPTIONS);
        }
        if (b) {
            user.setErrornum(0);
            user.setFreezetime(null);
            Date date = new Date();
            String tokne = null;
            tokne = (String) userredis(redisTemplate).opsForValue().get(user.getUsername());
            if (tokne == null) {
                try {
                    tokne = MD5Until.md5(user.getUsername() + date.toString());
                } catch (Exception e) {
                    throw new PanExection(ResultEmus.EXCEPTIONS);
                }
                String token = user.getUsername() + "_" + tokne;
                user.setToken(token);
                userRepository.saveAndFlush(user);
                userredis(redisTemplate).opsForValue().set(username, token, 1, TimeUnit.DAYS);
            }
            return user;
        } else {
            if (user.getErrornum() > 4) {
                user.setErrornum(user.getErrornum() + 1);
                user.setFreeze(FreezeEmus.DELETE.getCode());
                user.setFreezetime(new Date());
                userRepository.saveAndFlush(user);
                throw new PanExection(ResultEmus.USER_FREE);
            } else {
                Integer err = user.getErrornum() + 1;
                user.setErrornum(err);
                userRepository.saveAndFlush(user);
                throw new PanExection(ResultEmus.USER_ERROR_PASSWORD);
            }
        }
    }
}

　　

ResultEmus.java

@Getter
public enum ResultEmus {
    SUCCESS_REQUEST(0, "成功"),
    USER_NOT_EXIT(1, "用户不存在"),
    USER_BIND(2, "用户已经绑定"),
    USER_DELETE(3, "用户已经删除"),
    EXCEPTIONS(4, "转化异常"),
    USER_ERROR_PASSWORD(225, "密码错误"),
    USER_ERRPOR_EMAIL(6, "邮箱不匹配"),
    PARM_ERROR(7, "参数错误"),
    USER_EXIT(8, "用户已经存在")
  ;
    private Integer code;
    private String message;

    ResultEmus(Integer code, String message) {
        this.code = code;
        this.message = message;
    }
}

MD5Until.java

public class MD5Until {
    public static String md5(String text) throws Exception {
        MessageDigest md5 = MessageDigest.getInstance("MD5");
        BASE64Encoder base64en = new BASE64Encoder();
        String newstr = base64en.encode(md5.digest(text.getBytes()));
        return newstr;
    }

    public static boolean checkoutpassword(String password, String oldpassword) throws Exception {
        return md5(password).equals(oldpassword);
    }

}

　　

　　

开发完server端，我们去写controller

@RestController
@RequestMapping("/plan")
public class LoginContorl {
    @Autowired
    private UserSerice userSerice;
@GetMapping("/logins")
    public ModelAndView login(ModelAndView modelAndView) {
        modelAndView.setViewName("login");
        return modelAndView;
    }

    @PostMapping("/logins")
    public ModelAndView login(ModelAndView modelAndView, @Valid UserForm userVo, BindingResult bindingResult,
                              HttpServletRequest httpServletRequest) {

        HttpSession session = httpServletRequest.getSession();
        if (bindingResult.hasErrors()) {
            modelAndView.addObject("error", bindingResult.getFieldError().getDefaultMessage());
            modelAndView.setViewName("/plan/logins");
            return modelAndView;
        }
        String userName = userVo.getUsername();
        String password = userVo.getPassword();
        try {
            User user = userSerice.login(userName, password);
            session.setMaxInactiveInterval(3600);
            session.setAttribute("userid", user.getId());
            session.setAttribute("username", user.getUsername());
            return new ModelAndView("redirect:/web/index");
        } catch (PanExection e) {
            modelAndView.addObject("error", e.getMessage());
            modelAndView.setViewName("login");
            return modelAndView;
        }
    }
}

那么我们需要去写对应的html

html写在templates   ，login接口如下

<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<head>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
    <title>AutoTestPlatform</title>

    <link rel="stylesheet" th:href="@{/css/style.css}" href="../static/css/style.css">

    <link rel="shortcut icon" th:href="@{/images/favicon.png}" href="../static/images/favicon.png" />
</head>

<body>
<div class="body-wrapper">
    <div class="page-wrapper">
        <main class="content-wrapper auth-screen">

                                        <!--/*@thymesVar id="error" type=""*/-->
                                        <span id="basic-addon0"> </span>
                                        <span style="font-size: 12px;color: red" th:text="${error}" aria-describedby="basic-addon0"></span>
                                        <br />
                                    </div>
                                    <div class="mdc-layout-grid">
                                        <div class="mdc-layout-grid__inner">
                                            <div class="mdc-layout-grid__cell stretch-card mdc-layout-grid__cell--span-12">

                                            <div class="mdc-layout-grid__cell stretch-card mdc-layout-grid__cell--span-12">

</html>

　　

这样我们整个界面就开发完毕，我们进行调试测试

 前面插入的数据是 liwanlei  密码是：111111

登录后跳转到首页

补充首页代码

<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<head>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
    <title>AutoTestPlatform</title>
</head>
<h1>hello</h1>
<body>

至此  我们登录开发完毕
