java 开发国标gb28181代码

实现 GB28181 标准的视频监控系统，需要涉及到很多领域的知识，包括网络通信、视频编解码、设备管理等。下面给出一个简单的 Java 代码示例，用于实现基本的设备管理和视频流传输功能：

1. 引入相关依赖库

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;
import org.springframework.context.annotation.Bean;
import org.springframework.web.client.RestTemplate;

@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class})
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }

    // 配置 RestTemplate
    @Bean
    public RestTemplate restTemplate() {
        return new RestTemplate();
    }

}

2. 实现设备管理功能

import java.util.List;

public interface DeviceService {

    // 获取设备列表
    List<Device> getDeviceList();

    // 获取设备信息
    Device getDeviceInfo(String deviceId);

    // 添加设备
    boolean addDevice(Device device);

    // 删除设备
    boolean deleteDevice(String deviceId);

    // 修改设备信息
    boolean updateDevice(Device device);

}

import org.springframework.stereotype.Service;

import java.util.ArrayList;
import java.util.List;

@Service
public class DeviceServiceImpl implements DeviceService {

    // 模拟设备列表数据
    private static List<Device> deviceList = new ArrayList<>();

    static {
        deviceList.add(new Device("device001", "192.168.1.100", 8000, "admin", "123456"));
        deviceList.add(new Device("device002", "192.168.1.101", 8000, "admin", "123456"));
        deviceList.add(new Device("device003", "192.168.1.102", 8000, "admin", "123456"));
    }

    @Override
    public List<Device> getDeviceList() {
        return deviceList;
    }

    @Override
    public Device getDeviceInfo(String deviceId) {
        for (Device device : deviceList) {
            if (device.getDeviceId().equals(deviceId)) {
                return device;
            }
        }
        return null;
    }

    @Override
    public boolean addDevice(Device device) {
        if (getDeviceInfo(device.getDeviceId()) != null) {
            return false;
        }
        deviceList.add(device);
        return true;
    }

    @Override
    public boolean deleteDevice(String deviceId) {
        for (Device device : deviceList) {
            if (device.getDeviceId().equals(deviceId)) {
                deviceList.remove(device);
                return true;
            }
        }
        return false;
    }

    @Override
    public boolean updateDevice(Device device) {
        Device oldDevice = getDeviceInfo(device.getDeviceId());
        if (oldDevice == null) {
            return false;
        }
        oldDevice.setIp(device.getIp());
        oldDevice.setPort(device.getPort());
        oldDevice.setUsername(device.getUsername());
        oldDevice.setPassword(device.getPassword());
        return true;
    }

}

3. 实现视频流传输功能

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.client.RestTemplate;

import javax.servlet.http.HttpServletResponse;
import java.io.IOException;

@Controller
public class VideoController {

    @Autowired
    private RestTemplate restTemplate;

    // 获取视频流
    @GetMapping("/video/{deviceId}")
    public void getVideoStream(@PathVariable("deviceId") String deviceId, HttpServletResponse response) {
        Device device = deviceService.getDeviceInfo(deviceId);
        if (device == null) {
            response.setStatus(HttpServletResponse.SC_NOT_FOUND);
            return;
        }
        String url = "http://" + device.getIp() + ":" + device.getPort() + "/video";
        try {
            byte[] videoData = restTemplate.getForObject(url, byte[].class);
            response.getOutputStream().write(videoData);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

}

这里的实现仅为示例，实际开发中需要根据具体需求进行更详细的代码编写和测试。
