1、准备阶段

电脑和idea这个肯定是要准备的，然后准备几台（或一台）支持国标对接的摄像头。要知道摄像头的访问地址账号和密码。

1.1、我们会学到什么？

在这个项目中我们会用到一些设计模式以及一些注解平时可能不太常用的注解。我们还额外的知道了与物联网相关的一些对接知识。（文章中可能更多的是代码上的，为了便于大家直接CV。对于理论知识的大家可以私我，我可以出一期视频讲解这个项目）

1.2、创建项目

我们在这里创建的是一个WebFlux的项目，便须后期处理设备的命令。

结构如下：（ps: 在idea的Terminal中输入tree或者tree -f，-f会包含目录下文件名）

tree

tree -f

tree /f >> D:/tree.txt

1.3、pom中用到的依赖

&emsp(这里只放了dependencies)SIP依赖特别需要。

 
        
        
            org.springframework.boot
            spring-boot-starter
            
                
                    spring-boot-starter-logging
                    org.springframework.boot
                
            
        
        
            org.springframework.boot
            spring-boot-starter-aop
        
        
            org.springframework.boot
            spring-boot-starter-webflux
        
        
            org.projectlombok
            lombok
            true
        
        
        
        
            javax.sip
            jain-sip-ri
            1.3.0-91
        
        
            log4j
            log4j
            1.2.17
        
        
        
            org.springframework.boot
            spring-boot-starter-log4j2

1.4 打开摄像头的网址(了解配置方式)

这里大家先看一下，熟悉摄像头配置位置，不用填写。

[实战]Springboot与GB28181摄像头对接。摄像头注册上线(一)，Springboot对接GB28181摄像头实战教程，摄像头注册上线指南（一）第1张

我这里用的是海康摄像头，摄像头的网页配置地址就是摄像头的ip地址。我们可以看到在平台接入的地方需要填写SIP的一些信息，以及提供服务的ip。

[实战]Springboot与GB28181摄像头对接。摄像头注册上线(一)，Springboot对接GB28181摄像头实战教程，摄像头注册上线指南（一）第2张

这个是我之前配置过的，对于新摄像头可能没有，不过没关系，我们在项目中配置成什么这里就填写成什么即可。

2、代码编写

2.1、增加项目配置

在前面我们创建好了项目，并知道了摄像头SIP的配置位置。接着我们在application.yml文件中增加我们的sip配置。

application.yml

server:
  port: 8087
sip:
  ip: 192.168.20.78
  port: 5060
  id: 34020000002000000001
  domain: 3402000000
  password: sg@123456

2.2、在config目录下创建SipConfig

需要在config目录下创建。

import lombok.Getter;
import lombok.Setter;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Configuration;
/**
 * @author by Guoshun
 * @version 1.0.0
 * @description SipConfig
 * @date 2024/3/22 10:44
 */
@Getter
@Setter
@Configuration
@ConfigurationProperties(prefix = SipConfig.SIP)
public class SipConfig {
    public static final String SIP = "sip";
    /**
     * 默认使用 0.0.0.0
     */
    private String monitorIp = "0.0.0.0";
    private String ip;
    private Integer port;
    private String id;
    private String password;
    private String domain;
}

2.3、在service目录下创建SipService

import gov.nist.javax.sip.SipProviderImpl;
import gov.nist.javax.sip.SipStackImpl;
import lombok.extern.slf4j.Slf4j;
import org.ougnuhs.gb.config.SipConfig;
import org.ougnuhs.gb.listener.MySipListener;
import org.ougnuhs.gb.utils.SIPDefaultProperties;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.DependsOn;
import javax.sip.*;
import java.util.Properties;
/**
 * @author by Guoshun
 * @version 1.0.0
 * @description SipService need SipConfig
 * @date 2024/3/22 11:02
 */
@Slf4j
@Configuration
public class SipService {
    @Autowired
    private SipConfig sipConfig;
    @Autowired
    private MySipListener mySipListener;
    private SipFactory sipFactory;
    private SipStackImpl sipStack;
    @Bean("sipFactory")
    SipFactory createSipFactory(){
        sipFactory = SipFactory.getInstance();
        sipFactory.setPathName("gov.nist");
        return sipFactory;
    }
    @Bean("sipStack")
    @DependsOn("sipFactory")
    SipStackImpl createSipStackImpl() throws PeerUnavailableException {
        Properties sipProperties = SIPDefaultProperties.getSipProperties(sipConfig.getMonitorIp(), false);
        sipStack =(SipStackImpl) sipFactory.createSipStack(sipProperties);
        return sipStack;
    }
    /**
     * 监听TCP 对于产生的异常需要在这个地方处理
     * @return
     * @throws Exception
     */
    @Bean("tcpSipProvider")
    @DependsOn("sipStack")
    public SipProviderImpl startTcpListener() throws Exception {
        // 创建SIP Provider并绑定到SIP Stack
        ListeningPoint lp = sipStack.createListeningPoint(sipConfig.getMonitorIp(), sipConfig.getPort(), "TCP");
        SipProviderImpl sipProvider = (SipProviderImpl)sipStack.createSipProvider(lp);
        // 注册SIP Servlet
        sipProvider.addSipListener(mySipListener);
        log.info("TCP Start SUCCESS");
        return sipProvider;
    }
    /**
     * 监听TCP 对于产生的异常需要在这个地方处理
     * @return
     * @throws Exception
     */
    @Bean("udpSipProvider")
    @DependsOn("sipStack")
    public SipProviderImpl startUdpListener() throws Exception {
        // 创建SIP Provider并绑定到SIP Stack
        ListeningPoint lp = sipStack.createListeningPoint(sipConfig.getMonitorIp(), sipConfig.getPort(), "UDP");
        SipProviderImpl sipProvider =  (SipProviderImpl)sipStack.createSipProvider(lp);
        // 注册SIP Servlet
        sipProvider.addSipListener(mySipListener);
        log.info("UDP Start SUCCESS");
        return sipProvider;
    }
}

2.4、在adapter目录下创建如下类

import org.springframework.beans.factory.InitializingBean;
import javax.sip.RequestEvent;
/**
 * @author by Guoshun
 * @version 1.0.0
 * @description SIP事件处理接口
 * @date 2024/3/22 13:59
 */
public interface ISIPEventHandler extends InitializingBean {
    /**
     * 事件处理方法
     * @param requestEvent
     */
    void process(RequestEvent requestEvent);
}

@Slf4j
public class SIPFactory {
    public static Map requestHandlerMap = new ConcurrentHashMap();
    public static void register(String key, ISIPEventHandler handler){
        if(!StringUtils.hasText(key) || ObjectUtils.isEmpty(handler)){
            log.info("error: key or handler is null");
            return;
        }
        requestHandlerMap.put(key, handler);
        log.info("id:{}, handler:{}, register success", key, handler );
    }
    public static ISIPEventHandler getInvokeStrategy(String key) throws NoSuchMethodException {
        if(!requestHandlerMap.containsKey(key)){
            throw new NoSuchMethodException("未找到执行该方法的策略 key: " + key);
        }
        return requestHandlerMap.get(key);
    }
}

2.5、在listener准备如下类

import javax.sip.SipListener;
/**
 * @author by Guoshun
 * @version 1.0.0
 * @description MySipService 继承 SipListener
 * @date 2024/3/22 11:14
 */
public interface MySipListener extends SipListener {
}

import lombok.extern.slf4j.Slf4j;
import org.ougnuhs.gb.adapter.SIPFactory;
import org.springframework.stereotype.Service;
import javax.sip.*;
/**
 * @author by Guoshun
 * @version 1.0.0
 * @description IMySipService 实现 MySipService
 * @date 2024/3/22 11:16
 */
@Slf4j
@Service
public class MySipListenerImpl implements MySipListener{
    /**
     * 摄像头上报事件
     * @param requestEvent
     */
    @Override
    public void processRequest(RequestEvent requestEvent) {
        String method = requestEvent.getRequest().getMethod();
        try {
            SIPFactory.getInvokeStrategy(method).process(requestEvent);
        }catch (Exception e){
            log.error("processRequest error", e);
        }
    }
    @Override
    public void processResponse(ResponseEvent responseEvent) {
        log.info("processResponse");
    }
    @Override
    public void processTimeout(TimeoutEvent timeoutEvent) {
        log.info("processTimeout");
    }
    @Override
    public void processIOException(IOExceptionEvent exceptionEvent) {
        log.info("processIOException");
    }
    @Override
    public void processTransactionTerminated(TransactionTerminatedEvent transactionTerminatedEvent) {
        log.info("processTransactionTerminated");
    }
    @Override
    public void processDialogTerminated(DialogTerminatedEvent dialogTerminatedEvent) {
        log.info("processDialogTerminated");
    }
}

2.7、准备基础的枚举类（enums目录下）

/**
 * @author by Guoshun
 * @version 1.0.0
 * @description 传输方式类型
 * @date 2024/3/27 9:52
 */
public enum TransportTypeEnum implements BaseEnum {
    TCP("TCP"),
    UDP("UDP");
    private String value;
    TransportTypeEnum(String value) {
        this.value = value;
    }
    public String getValue() {
        return value;
    }
    @Override
    public String getName() {
        return null;
    }
    public void setValue(String value) {
        this.value = value;
    }
}
