Use WebMan technology to implement online file management system

  随着信息化的发展，各类电子文档和档案呈现爆炸式增长，传统的纸质档案管理已经无法满足日益增长的档案管理需求。为了更高效地管理和利用档案，许多机构和企业开始采用在线档案管理系统。本文将介绍如何利用WebMan技术实现一个简单的在线档案管理系统，并提供相应的代码示例。

System requirements analysis

Before designing the online file management system, We need to first clarify the functional requirements of the system. According to the general file management needs, we can list the following main functional modules:

User management: manage system users, including adding users, deleting users, modifying user information, etc. Function.
File management: Add, delete, modify and check files, including uploading files, downloading files, editing files, deleting files and other functions.
File classification: Classify and manage files, including functions such as adding categories, deleting categories, modifying categories, etc.
File retrieval: Search files based on keywords to provide efficient search results.
Permission management: Manage user permissions, including setting user roles, assigning role permissions and other functions.

System design and implementation

The design and implementation of the online file management system is mainly divided into two parts: front-end and back-end. The front-end is mainly responsible for the display of the user interface and user interaction, and the back-end is responsible for processing user requests, data storage and business logic.

Front-end design and implementation: We can use front-end technologies such as HTML, CSS and JavaScript for interface design and interactive implementation. The following is a sample code for a simple login page:

<!DOCTYPE html>
<html>
<head>
    <title>登录</title>
    <link rel="stylesheet" type="text/css" href="styles.css">
</head>
<body>
    <div class="login-container">
        <h1>在线档案管理系统</h1>
        <form>
            <input type="text" name="username" placeholder="用户名" required>
            <input type="password" name="password" placeholder="密码" required>
            <button type="submit">登录</button>
        </form>
    </div>
</body>
</html>

Back-end design and implementation: We can use Java language and related frameworks to implement back-end functions. The following is a simple sample code that uses the Spring Boot framework to implement the user login interface:

@RestController
public class UserController {

    @Autowired
    private UserService userService;

    @PostMapping("/login")
    public String login(@RequestBody LoginRequest request) {
        User user = userService.getUserByUsername(request.getUsername());

        if (user != null && user.getPassword().equals(request.getPassword())) {
            return "登录成功";
        } else {
            return "用户名或密码错误";
        }
    }
}

@Data
public class LoginRequest {
    private String username;
    private String password;
}

@Entity
@Data
public class User {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;
    private String username;
    private String password;
}

  上述代码中，我们通过使用Spring Boot框架实现了一个简单的用户登录接口。当用户提交登录请求时，后端会根据用户名和密码进行验证，并返回相应的登录结果。

System deployment and operation

After completing the design and implementation of the system Finally, we need to deploy the system to the server for running. First, we need to package the front-end code and back-end code into static files and executable jar packages respectively. Then, place the static files in the static resource directory on the server, and deploy the executable jar package to the server. Finally, we can use the online archive management system by accessing the server's IP address and port number.
System optimization and expansion

In practical applications, we can also further optimize and expand the online file management system. For example, a caching mechanism can be introduced to improve system access speed, full-text search technology can be introduced to improve file retrieval efficiency, and functions such as progress prompts for file upload and download can be added to improve user experience.

In this article, we introduce how to use WebMan technology to implement a simple online file management system and give corresponding code examples. I hope this article can help readers understand the design and implementation of online archive management systems, and master the corresponding development skills through practice. At the same time, readers can also further optimize and expand according to specific needs in actual projects to meet more complex file management needs.
