springboot整合filezilla

要在Spring Boot中整合FileZilla，您需要使用Apache Commons Net库来实现FTP（文件传输协议）功能。

以下是整合FileZilla的步骤：

1. 添加Maven依赖：

<dependency>
    <groupId>commons-net</groupId>
    <artifactId>commons-net</artifactId>
    <version>3.8.0</version>
</dependency>

2. 创建一个FTPUtil类，用于处理FTP连接和文件传输操作：

import org.apache.commons.net.ftp.*;

public class FTPUtil {
    private FTPClient ftpClient;

    public FTPUtil() {
        ftpClient = new FTPClient();
    }

    public void connect(String server, int port, String username, String password) throws IOException {
        ftpClient.connect(server, port);
        ftpClient.login(username, password);
    }

    public void uploadFile(String localFilePath, String remoteFilePath) throws IOException {
        try (InputStream inputStream = new FileInputStream(localFilePath)) {
            ftpClient.storeFile(remoteFilePath, inputStream);
        }
    }

    public void disconnect() throws IOException {
        if (ftpClient.isConnected()) {
            ftpClient.logout();
            ftpClient.disconnect();
        }
    }
}

3. 在您的Spring Boot应用程序中使用FTPUtil类来上传文件：

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.*;
import org.springframework.web.multipart.MultipartFile;

@Controller
@RequestMapping("/file")
public class FileController {
    private static final String FTP_SERVER = "your_ftp_server";
    private static final int FTP_PORT = 21;
    private static final String FTP_USERNAME = "your_ftp_username";
    private static final String FTP_PASSWORD = "your_ftp_password";

    @PostMapping("/upload")
    @ResponseBody
    public String uploadFile(@RequestParam("file") MultipartFile file) {
        try {
            FTPUtil ftpUtil = new FTPUtil();
            ftpUtil.connect(FTP_SERVER, FTP_PORT, FTP_USERNAME, FTP_PASSWORD);
            ftpUtil.uploadFile(file.getInputStream(), file.getOriginalFilename());
            ftpUtil.disconnect();
            return "File uploaded successfully.";
        } catch (Exception e) {
            return "Failed to upload file: " + e.getMessage();
        }
    }
}
