Docker部署 实现弹幕+聊天室 vue+websocket+spring-boot
Docker 部署 实现直播后续

做了一些小修改
首先从弹幕功能开始
vue实现弹幕功能很简单，有一个插件叫vue-baberrage，我们只需要安装这个插件就能实现弹幕
cnpm i vue-baberrage
main.js加入
import { vueBaberrage } from 'vue-baberrage'
Vue.use(vueBaberrage);
界面
<vue-baberrage
:isShow="barrageIsShow"
:barrageList="barrageList"
:maxWordCount="maxWordCount"
:throttleGap="throttleGap"
:loop="barrageLoop"
:boxHeight="boxHeight"
:messageHeight="messageHeight"
:boxWidth="boxWidth-300"
>
</vue-baberrage>
<i-input v-model="sendmsg" placeholder="请输入..." style="width: 300px"></i-input>
<i-button type="primary" @click="addToList(2)">发送弹幕</i-button>
import { MESSAGE_TYPE } from 'vue-baberrage'
this.barrageList.push({//把数据加进去就可以了
id: ++this.currentId,
avatar: this.msgHeadImageURL,
msg: messageData.chatContent,
barrageStyle: "normal",
time: 5,
type: MESSAGE_TYPE.NORMAL,
position: "bottom"
});
然后是聊天室
聊天室需要websocket来实现，后端我用的spring-boot 搭建比较快捷
先是前端页面
<template>
<div>
WebSocket//这是一个样例
</div>
</template>
<script>
export default {
created() {
this.initWebSocket(); //进入页面开始初始化websocket建立连接
},
destroyed() {
this.websocketclose(); //离开页面断开连接
},
methods: {
initWebSocket() {
// WebSocket与普通的请求所用协议有所不同，ws等同于http，wss等同于https
this.websock = new WebSocket("wss://localhost"); //这里是websocket服务地址，这里的地址可以前端根据后台地址参数规则拼成，也可以向后端请求
this.websock.onopen = this.websocketonopen;
this.websock.onerror = this.websocketonerror;
this.websock.onmessage = this.websocketonmessage;
this.websock.onclose = this.websocketclose;
},
websocketonopen() {
console.log("WebSocket连接成功");
},
websocketonerror(e) {
console.log("WebSocket连接发生错误");
},
websocketonmessage(e) {
console.log(e.data); // console.log(e);
},
websocketclose(e) {
console.log("connection closed (" + e.code + ")");
},
}
}
</script>
页面源码
<template>
<div>
<div class="barrages-drop">
<video
id="videoId"
controls = "true"
:height="boxHeight+350"
:width="boxWidth">
</video>
<vue-baberrage
:isShow="barrageIsShow"
:barrageList="barrageList"
:maxWordCount="maxWordCount"
:throttleGap="throttleGap"
:loop="barrageLoop"
:boxHeight="boxHeight"
:messageHeight="messageHeight"
:boxWidth="boxWidth-300"
>
</vue-baberrage>
<Card style="float: right;height: 500px;width: 500px;">
<Scroll height="450">
<ul v-for="item in msgs">

上线的话，解决跨域问题 可以用nginx反向代理 也可以在后端加个配置
跨域配置
package com.macro.mall.tiny.config;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.CorsRegistry;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
/**

*/
@Configuration
@EnableWebMvc
public class CorsConfig extends WebMvcConfigurerAdapter {
@Override
public void addCorsMappings(CorsRegistry registry) {
registry.addMapping("/**");
}
}
带websocket的项目打包会报错 需要在pom加入
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<configuration>
<skip>true</skip>
</configuration>
</plugin>
然后点package
jar包完成
连接服务器rz传文件
[root@VM_0_2_centos ~]# rz
写Dockerfile文件
[root@VM_0_2_centos ~]# cat Dockerfile
FROM java:8
VOLUME /tmp
ADD mall-tiny-02-0.0.1-SNAPSHOT.jar app.jar
RUN bash -c 'touch /app.jar'
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"]
运行build命令 运行run命令
[root@VM_0_2_centos ~]# docker build -t mall .
[root@VM_0_2_centos ~]# docker run -d -p 8888:8081 mall
[root@VM_0_2_centos ~]# docker ps

到这里java项目已经运行起来了
前端打包
cnpm run build
会生成dist文件夹，压缩上传服务器
[root@VM_0_2_centos ~]# rar x dist.rar//解压
然后运行nginx 把容器里的项目目录挂载到dist的解压目录 配置文件也挂载出来
[root@VM_0_2_centos ~]# docker run -d -p 443:443 -p 80:80 -v /root/filebrowser/sites/root/nginx配置/nginx.conf:/etc/nginx/nginx.conf -v /root/filebrowser/sites/root/nginx项目:/usr/share/nginx/html nginx
dece8fc43c67 nginx:latest "nginx -g 'daemon ..." 5 months ago Up 2 days 0.0.0.0:80->80/tcp, 0.0.0.0:443->443/tcp nginx
然后写nginx.conf
location / {
root /usr/share/nginx/html/xm1/dist;
index index.html index.htm;
try_files $uri $uri/ /index.html;
}
重启nginx
这些做完之后，就已经完成了。
