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：

复制代码
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';
复制代码

 

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
复制代码
<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>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>
复制代码

 

添加依赖后同步更新。

在application.yaml 进行配置

复制代码
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
复制代码

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

复制代码
@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;
}
复制代码

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);
}

public interface UserSerice {
 
    User login(String username, String password);
 
}

    }
 
  public User login_is(User user, String password, String username) {

                    userRepository.saveAndFlush(user);

            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());

    }
 
    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

复制代码
@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;
        }
    }
}
复制代码

那么我们需要去写对应的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
