#### 项目介绍
1. 聊天盒子是一个仿微信实现的网页版聊天软件，目前完全开源，仅用于学习和交流。
2. 支持私聊、群聊、离线消息、发送图片、文件、好友在线状态显示等功能。
3. 后端采用springboot+netty实现，前端使用vue。
4. 服务器支持集群化部署，每个chat-server仅处理自身连接用户的消息
#### 项目结构
| 模块 | 功能 |
|---------------|------------|
| chat-platform | 与页面进行交互，处理业务请求 |
| chat-server | 推送聊天消息|
| chat-client | 消息推送sdk|
| chat-common | 公共包 |
#### 消息推送方案
- 当消息的发送者和接收者连的不是同一个server时，消息是无法直接推送的，所以我们需要设计出能够支持跨节点推送的方案
- 利用了redis的list数据实现消息推送，其中key为im:unread:${serverid},每个key的数据可以看做一个queue,每个chat-server根据自身的id只消费属于自己的queue
- redis记录了每个用户的websocket连接的是哪个chat-server,当用户发送消息时，chat-platform将根据所连接的chat-server的id,决定将消息推向哪个queue
#### 本地快速部署
1.安装运行环境
- 安装node:v14.16.0
- 安装jdk:1.8
- 安装maven:3.6.3
- 安装mysql:5.7,密码分别为root/root,运行sql脚本(脚本在chat-platfrom的resources/db目录)
- 安装redis:4.0
- 安装minio，命令端口使用9001，并创建一个名为"chat-box"的bucket，并设置访问权限为公开
2.启动后端服务
```
mvn clean package
java -jar ./chat-platform/target/chat-platform.jar
java -jar ./chat-server/target/chat-server.jar
```
3.启动前端ui
```
cd chat-ui
npm install
npm run serve
```
4.访问localhost:8080
#### 快速接入
消息推送的请求代码已经封装在chat-client包中，对于需要接入chat-server的小伙伴，可以按照下面的教程快速的将聊天功能集成到自己的项目中。
注意服务器端和网页端都需要接入，服务器端发送消息，网页端接收消息。
4.1 服务器端接入
引入pom文件
```
<dependency>
<groupId>com.box</groupId>
<artifactId>chat-client</artifactId>
<version>1.1.0</version>
</dependency>
```
内容使用了redis进行通信,所以要配置redis地址：
```
spring:
redis:
host: 127.0.0.1
port: 6379
```
直接把IMClient通过@Autowire导进来就可以发送消息了，IMClient 只有2个接口：
```
public class IMClient {
/**
* 发送私聊消息
*
* @param recvId 接收用户id
* @param messageInfo 消息体，将转成json发送到客户端
*/
void sendPrivateMessage(Long recvId, PrivateMessageInfo... messageInfo)；
/**
* 发送群聊消息
*
* @param recvIds 群聊用户id列表
* @param messageInfo 消息体，将转成json发送到客户端
*/
void sendGroupMessage(List<Long> recvIds, GroupMessageInfo... messageInfo)；
}
```
发送私聊消息(群聊也是类似的方式)：
```
@Autowired
private IMClient imClient;
public void sendMessage(){
PrivateMessageInfo messageInfo = new PrivateMessageInfo();
Long recvId = 1L;
messageInfo.setId(123L);
messageInfo.setContent("你好呀");
messageInfo.setType(MessageType.TEXT.getCode());
messageInfo.setSendId(userId);
messageInfo.setRecvId(recvId);
messageInfo.setSendTime(new Date());
imClient.sendPrivateMessage(recvId,messageInfo);
}
```
如果需要对消息发送的结果进行监听的话，实现MessageListener,并加上@IMListener即可
```
@Slf4j
@IMListener(type = IMListenerType.ALL)
public class PrivateMessageListener implements MessageListener {
@Override
public void process(SendResult result){
PrivateMessageInfo messageInfo = (PrivateMessageInfo) result.getMessageInfo();
if(result.getStatus().equals(IMSendStatus.SUCCESS)){
// 消息发送成功
log.info("消息已读，消息id:{}，发送者:{},接收者:{}",messageInfo.getId(),messageInfo.getSendId(),messageInfo.getRecvId());
}
}
}
```
4.2 网页端接入
首先将chat-ui/src/api/wssocket.js拷贝到自己的项目。
接入代码如下：
```
import * as wsApi from './api/wssocket';
let wsUrl = 'ws://localhost:8878/im'
let userId = 1;
wsApi.createWebSocket(wsUrl , userId);
wsApi.onopen(() => {
// 连接打开
console.log("连接成功");
});
wsApi.onmessage((cmd,messageInfo) => {
if (cmd == 2) {
// 异地登录，强制下线
console.log("您已在其他地方登陆，将被强制下线");
} else if (cmd == 3) {
// 私聊消息
console.log(messageInfo);
} else if (cmd == 4) {
// 群聊消息
console.log(messageInfo);
}
})
```
