信使是一个简洁的 IM。核心目标: 完成单机10W+的可用项目(目前实现网页端和electron实现的Win端)

技术栈

核心Tio,包括http和socket都是tio.没有引入spring系列，所以大部分的内容都需要自己封装，好处是启动快，体积小。弊端就是方方面面都需要自己考虑。从登录开始所有的交互全部使用socket，除minio分片上传使用了http外，目前没有其他使用http的地方。文件存储使用了minio, 缓存使用mangodb, 同时解决缓存和数据存储的问题（据说挺快的，没有做大量尝试）

使用

运行ImServer下Main方法

打包

运行 mvn clean package 拷贝Target下 Im-Server目录 Windows下执行startup.bat方法,Linux执行startup.sh

🤣蓝图

在线文档

🎉前端UI

目前有一些初略的想法,基于electron和web实现,已有一些雏形,但短期目标还是集中在实现功能上面

安装教程

教程来自windows docker， linux同理

安装minio

docker run -d -p 9000:9000 -p 9001:9001 --name minio -v /home/minio/data:/data -v /home/minio/cert:/root/.minio -e "MINIO_ROOT_USER=AKIAIOSFODNN7EXAMPLE" -e "MINIO_ROOT_PASSWORD=wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY" --restart=always quay.io/minio/minio server /data --console-address ":9001"

安装MongoDB

docker run --name mongo --restart=always -p 27017:27017 -v /home/mongodb:/data/db -e MONGO_INITDB_ROOT_USERNAME=admin -e MONGO_INITDB_ROOT_PASSWORD=密码  -d mongo:latest mongod --auth

安装nginx，作者使用nginxWebui

# Linux
docker run -itd -v /home/nginxWebUI:/home/nginxWebUI -e BOOT_OPTIONS="--server.port=8080" --privileged=true --restart=always --net=host cym1102/nginxwebui:latest

# Windows
docker run -itd -p 8080:8080 -p 8888:8888 -v E:/docker/nginxWebUI:/home/nginxWebUI -e BOOT_OPTIONS="--server.port=8080" --privileged=true  cym1102/nginxwebui:latest

配置minio https访问（此处以自签名为例）下载签名工具签名工具

使用公网证书可忽略生成的步骤，直接讲证书放进去即可

# 172.17.0.3 是docker minio内部IP， 需要特别注意这个IP在映射出端口的情况下必须写
certgen-windows-amd64.exe -ecdsa-curve P256 -host 127.0.0.1,localhost,172.17.0.3,192.168.0.103

放置于

抛出的 E:/docker/minio/cert 目录下，完整目录为 E:/docker/minio/cert/certs 重启容器

配置JDK证书信任，否则会抛出下列错误

javax.net.ssl.SSLHandshakeException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
	at java.base/sun.security.ssl.Alert.createSSLException(Alert.java:131)
	at java.base/sun.security.ssl.TransportContext.fatal(TransportContext.java:371)
	at java.base/sun.security.ssl.TransportContext.fatal(TransportContext.java:314)

在JDK bin目录下运行

.\keytool -import -alias sslServer_03 -file D:\key\新建文件夹\public.crt -keystore ..\lib\security\cacerts -storepass changeit -v
