## 一、系统功能介绍 ##

本系统后台采用ssm框架编写，前台采用当前主流的layui框架和jquery框架完成页面信息展示功能。  
开发环境：  
（1）开发工具：eclipse  
（2）数据库：mysql-8.0.16-winx64  
（3）JDK：1.8.0\_202  
（4）JDBC：8.0.16

**包结构：**

## 二、系统实现 ##

### 1.注册模块 ###

注册模块用于管理员或读者注册，通过此模块将用户信息注入到读者表或管理员表。登录者根据自己注册的账号，密码和身份（管理员或读者）进行登录时，将会对读者表或管理员录入的信息表进行查找。如图3.1所示。

图3.1 注册界面图：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDc5NzUzOQ_size_16_color_FFFFFF_t_70 1]

### 2.登录模块 ###

登录模块用于管理员或读者登录，通过此模块进入图书管理系统。登录者根据自己的账号，密码和身份（管理员或读者）进行登录时，将会对读者表或管理员的信息表进行查找对比，当信息匹配时，登录成功。当身份是管理员时，进入管理员界面，管理员可以操作的模块有图书管理，读者管理，借书管理。当身份是读者时，进入读者界面，读者可以操作的模块有借阅图书，归还图书。如图3.2、图3.3、图3.4所示。

图3.2 登录界面图：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDc5NzUzOQ_size_16_color_FFFFFF_t_70 2]  
图3.3 管理员界面图：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDc5NzUzOQ_size_16_color_FFFFFF_t_70 3]

图3.4 读者界面图：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDc5NzUzOQ_size_16_color_FFFFFF_t_70 4]

### 3.图书管理模块 ###

图书管理模块可添加、删除、修改、查询图书，图书主要有图书ID，图书名、作者、数量等信息，图书在管理员界面和读者界面共享，但只有管理员能对图书进行增删查改。借阅表，还书表，借阅记录表都依赖于图书表，如图3.5、图3.6、图3.7、图3.8、图3.9、图3.10所示。

图3.5图书管理界面图：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDc5NzUzOQ_size_16_color_FFFFFF_t_70 5]

图3.6添加图书界面图：

图3.7删除图书界面图：

图3.8查询图书界面图：

图3.9查询结果界面图：

图3.10修改图书界面图：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDc5NzUzOQ_size_16_color_FFFFFF_t_70 10]

### 4.读者管理模块 ###

读者管理模块可添加、删除、修改、查询读者，读者主要有读者ID，读者姓名、读者密码、性别等信息，只有管理员能对读者进行增删查改。如图3.11、图3.12、图3.13、图3.14、图3.15、图3.16所示。

图3.11读者管理界面图：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDc5NzUzOQ_size_16_color_FFFFFF_t_70 11]

图3.12、图3.13、图3.14、图3.15、图3.16跟上个图书管理模块的增删查改界面类似，怕图太多，就不截出来了。

### 5.借书管理模块 ###

借书管理模块用于管理员查看读者的借阅记录，可以根据书名，图书ID，读者ID，借阅状态等对借阅记录进行查询。借阅记录表依赖于借书表和还书表，如图3.17、图3.18所示。

图3.17 借书管理界面图：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDc5NzUzOQ_size_16_color_FFFFFF_t_70 12]

图3.18 查询结果界面图：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDc5NzUzOQ_size_16_color_FFFFFF_t_70 13]

### 6.借阅图书模块 ###

借阅图书模块是读者选择自己想要的图书借阅的模块，读者选择自己想要借阅的图书并填入自己的学号即可借阅。如图5.19、图5.20所示。

图3.19借阅图书管理界面图：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDc5NzUzOQ_size_16_color_FFFFFF_t_70 14]  
图3.20借阅图书界面图  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDc5NzUzOQ_size_16_color_FFFFFF_t_70 15]

### 7.归还模块 ###

归还模块用于读者归还图书，读者选择自己想要归还的图书并填入自己的学号即可归还图书。图3.21、图3.22跟上个借阅图书模块类似，就不截出来了。

### 8.访问拦截与权限控制子模块 ###

访问拦截与权限控制子模块是本系统的安全性保证，此模块保证用户不能访问不属于自己身份的界面，管理员接口不能访问读者接口，读者接口不能访问管理员接口，实现接口隔离，防止越权操作。此模块依赖读者表和管理员表，如图3.23所示。

图3.23访问拦截与权限控制界面图：

    }

    		User user = userdao.FindUser(user_code, user_passwd);
    		
    		return user;
    	}
    
    	// 添加管理员
