spring boot 与 iview 前后端分离架构之基于socketIo的消息推送的实现（三十三）
- 公众号
- websocket的实现
websocket的实现
bug修复
在前面我们已经实现了类oauth2的鉴权机制，但是当时我们的前端少写了刷新token的地址，因此在三十三章之前我们都是无法在页面端实现token的刷新，因此本章我们补足该缺陷，同时配置本章websocket的地址，修改config目录底下的dev.js，改造完成以后的代码如下：
export const runDevConfig = {
baseUrl: 'http://127.0.0.1:8288',
imgUrl: 'http://127.0.0.1:80/merJoinResource',
refreshTokenUrl: 'http://127.0.0.1:8288/user/refreshToken',
socketUrl: 'http://127.0.0.1:9099'
};
后端改造
socketIo的后端实现
在config包底下创建一个socketio的包，在该包中添加以下的实现
PushMessage
package com.github.bg.admin.core.config.socketio;
/**
* @author linzf
* @since 2019-06-13
* 类描述：socket消息发送实体类
*/
public class PushMessage {
/**
* 登录socket的socketToken
*/
private String socketToken;
/**
* 推送的内容
*/
private String content;
/**
* 空的构造函数
*/
public PushMessage() {
super();
}
/**
* 构造函数
* @param socketToken
* @param content
*/
public PushMessage(String socketToken, String content) {
this.socketToken = socketToken;
this.content = content;
}
public String getSocketToken() {
return socketToken;
}
public void setSocketToken(String socketToken) {
this.socketToken = socketToken;
}
public String getContent() {
return content;
}
public void setContent(String content) {
this.content = content;
}
}
SocketIoConfig
package com.github.bg.admin.core.config.socketio;
import com.corundumstudio.socketio.SocketConfig;
import com.corundumstudio.socketio.SocketIOServer;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
/**
* @author linzf
* @since 2019-06-13
* 类描述：socketIo的配置类
*/
@Configuration
public class SocketIoConfig {
@Value("${socketio.host}")
private String host;
@Value("${socketio.port}")
private Integer port;
@Value("${socketio.bossCount}")
private int bossCount;
@Value("${socketio.workCount}")
private int workCount;
@Value("${socketio.allowCustomRequests}")
private boolean allowCustomRequests;
@Value("${socketio.upgradeTimeout}")
private int upgradeTimeout;
@Value("${socketio.pingTimeout}")
private int pingTimeout;
@Value("${socketio.pingInterval}")
private int pingInterval;
/**
* 以下配置在上面的application.yml中已经注明
* @return 实例化socketIo的服务对象
*/
@Bean
public SocketIOServer socketIOServer() {
SocketConfig socketConfig = new SocketConfig();
socketConfig.setTcpNoDelay(true);
socketConfig.setSoLinger(0);
com.corundumstudio.socketio.Configuration config = new com.corundumstudio.socketio.Configuration();
config.setSocketConfig(socketConfig);
config.setHostname(host);
config.setPort(port);
config.setBossThreads(bossCount);
config.setWorkerThreads(workCount);
config.setAllowCustomRequests(allowCustomRequests);
config.setUpgradeTimeout(upgradeTimeout);
config.setPingTimeout(pingTimeout);
config.setPingInterval(pingInterval);
return new SocketIOServer(config);
}
}
application-dev.yml增加以下配置
#============================================================================
# netty socket io setting
#============================================================================
# host在本地测试可以设置为localhost或者本机IP，在Linux服务器跑可换成服务器IP
socketio:
host: localhost
port: 9099
# 设置最大每帧处理数据的长度，防止他人利用大数据来***服务器
maxFramePayloadLength: 1048576
# 设置http交互最大内容长度
maxHttpContentLength: 1048576
# socket连接数大小（如只监听一个端口boss线程组为1即可）
bossCount: 1
workCount: 100
allowCustomRequests: true
# 协议升级超时时间（毫秒），默认10秒。HTTP握手升级为ws协议超时时间
upgradeTimeout: 1000000
# Ping消息超时时间（毫秒），默认60秒，这个时间间隔内没有接收到心跳消息就会发送超时事件
pingTimeout: 6000000
# Ping消息间隔（毫秒），默认25秒。客户端向服务器发送一条心跳消息间隔
pingInterval: 25000
SocketIoService
package com.github.bg.admin.core.config.socketio;
public interface SocketIoService {
/**
* 推送的事件
*/
String PUSH_EVENT = "push_event";
/**
* 启动服务
*
* @throws Exception
*/
void start() throws Exception;
/**
* 停止服务
*/
void stop();
/**
* 功能描述：实现消息的发送
*
* @param loginAccount 需要发送到的账号
* @param content 需要发送的内容
*/
void pushMessage(String loginAccount, String content);
}
SocketIoService的实现SocketIoServiceImpl
在socketio包底下创建一个impl包同时创建SocketIoServiceImpl.java代码如下：
package com.github.bg.admin.core.config.socketio.impl;
import com.corundumstudio.socketio.SocketIOClient;
import com.corundumstudio.socketio.SocketIOServer;

/**

UserInfo工具类的实现
package com.github.bg.admin.core.util;

String token = request.getHeader("x-access-token");
if("".equals(token)){
return null;
}
return redisCache.getObject(token + "_USER",User.class);
}
}
执行以下脚本创建消息相关表
CREATE TABLE `t_message` (
`messageId` varchar(32) NOT NULL COMMENT '消息流水ID',
`title` varchar(100) DEFAULT NULL COMMENT '消息标题',
`content` varchar(500) DEFAULT NULL COMMENT '消息内容',
`crtDate` datetime DEFAULT NULL COMMENT '创建事件',
`crtUserId` varchar(32) DEFAULT NULL COMMENT '创建用户ID',
`crtUserName` varchar(100) DEFAULT NULL COMMENT '创建用户名称',
`type` varchar(2) DEFAULT NULL COMMENT '消息类型【1：系统消息；2：其他消息】',
PRIMARY KEY (`messageId`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COMMENT='用于存放主体的消息信息';
CREATE TABLE `t_target_message` (
`targetMessageId` varchar(32) NOT NULL COMMENT '流水ID',
`messageId` varchar(32) DEFAULT NULL COMMENT '消息流水ID',
`state` varchar(2) DEFAULT NULL COMMENT '消息状态【1：未读；2：已读】',
`userId` varchar(32) DEFAULT NULL COMMENT '用户ID',
`sendTime` datetime DEFAULT NULL COMMENT '发送时间',
`readeTime` datetime DEFAULT NULL COMMENT '阅读时间',
`removeState` varchar(2) DEFAULT NULL COMMENT '删除状态【0：已删除；1：正常】',
PRIMARY KEY (`targetMessageId`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COMMENT='用于接收消息的表';
通过tk.mybatis工具生成实体和代码
打开generatorConfig.xml修改成如下代码：
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE generatorConfiguration
PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
"http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">
<generatorConfiguration>
<context id="Mysql" targetRuntime="MyBatis3Simple" defaultModelType="flat">

<property name="endingDelimiter" value="`"/>
<plugin type="tk.mybatis.mapper.generator.MapperPlugin">
<property name="mappers" value="tk.mybatis.mapper.common.Mapper"/>
<!-- 是否区分大小写，默认值 false -->
<property name="caseSensitive" value="true"/>
<!-- 是否强制生成注解，默认 false，如果设置为 true，不管数据库名和字段名是否一致，都会生成注解（包含 @Table 和 @Column） -->
<property name="forceAnnotation" value="true"/>
</plugin>
<jdbcConnection driverClass="com.mysql.jdbc.Driver"
connectionURL="jdbc:mysql://127.0.0.1:3306/vcm?characterEncoding=utf-8"
userId="root"
password="123456">
</jdbcConnection>
<javaModelGenerator targetPackage="com.github.bg.admin.core.entity" targetProject="src/main/java">
</javaModelGenerator>
<sqlMapGenerator targetPackage="mybatis/mapper" targetProject="src/main/resources" />
<javaClientGenerator targetPackage="com.github.bg.admin.core.dao" targetProject="src/main/java" type="XMLMAPPER"/>
<table tableName="t_message" domainObjectName="Message" mapperName="MessageDao">
<!-- 字段属性是否驼峰展示，true为驼峰展示 -->
<property name="useActualColumnNames" value="true"></property>
<generatedKey column="messageId" sqlStatement="JDBC"/>
</table>
<table tableName="t_target_message" domainObjectName="TargetMessage" mapperName="TargetMessageDao">
<!-- 字段属性是否驼峰展示，true为驼峰展示 -->
<property name="useActualColumnNames" value="true"></property>
<generatedKey column="targetMessageId" sqlStatement="JDBC"/>
</table>
</context>
</generatorConfiguration>
然后在执行插件的方法如下
引入socket.io的maven依赖
在pom.xml中引入socket.io的依赖。
<dependency>
<groupId>com.corundumstudio.socketio</groupId>
<artifactId>netty-socketio</artifactId>
<version>1.7.7</version>
</dependency>

前端改造
user.js改造
store/modules底下的user.js的handleLogin方法进行改造，改造完成以后的代码如下：
handleLogin ({ commit }, {loginAccount, loginPassword}) {
loginAccount = loginAccount.trim();
return new Promise((resolve, reject) => {
login({
loginAccount,
loginPassword
}).then(res => {
if(res.code!=200){
commit('setMsg', res.msg);
}else{
localStorage.setItem('token', res.obj.token);
localStorage.setItem('refreshToken', res.obj.refreshToken);
commit('setToken', res.obj.token);
commit('setRefreshToken', res.obj.refreshToken);
}
resolve(res);
}).catch(err => {
reject(err);
});
})
}
引入socket.io-client
在package.json的dependencies底下加入以下的依赖：
"socket.io-client": "^2.2.0"
接着下载依赖，执行以下代码
cnpm install
编写生成uuid的方法
在main.js中加入以下的代码，实现全局可用。
/**
* 生成唯一的uuid
* @returns {string}
*/
Vue.prototype.$uuid = function(){
return 'xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx'.replace(/[xy]/g, function(c) {
let r = Math.random()*16|0, v = c == 'x' ? r : (r&0x3|0x8);
return v.toString(16);
});
};
添加msg的api
在api目录底下创建一个msg文件夹，接着在该文件夹底下创建一个msg.api.js，代码如下：
import {fetch} from '../../base';
// 实现消息的阅读
export const readMsg = params => {
return fetch('/msg/readMsg',params);
};
// 获取当前登录的用户的未读的消息
export const queryUserMsg = params => {
return fetch('/msg/queryUserMsg',params);
};
// 发布消息
export const publishNews = params => {
return fetch('/msg/publishNews',params);
};
// 获取消息列表
export const queryMessageList = params => {
return fetch('/msg/queryMessageList',params);
};
main.vue改造

运行项目
我们将整个项目运行起来，然后直接访问到我们的消息管理模块，我们会看到如下的页面：
接着我们发送一条消息会看到如下的效果则说明我们的消息模块已经完成了。
