iogame服务端游戏框架整合springboot + mybatisplus
概述
本次测试为了记录第一次尝试游戏开发的过程，项目使用了游戏服务端开源框架iogame iogame gitee源码，前端采用uniapp框架，Vue3+js，后端使用springboot+mybatisplus，数据库版本为mysql5.7结合的方式开发一个h5 demo。对于iogame框架不熟悉的同学可以先移步 iogame说明介绍文档 观看相关介绍文档。
文章目录
| 使用框架组件 | 版本 | 备注 |
|---|---|---|
| iogame | 17.1.38 | |
| JDK | 17 | |
| springboot | 2.7.0 | |
| mybatis-plus | 3.5.3.1 | |
| mysql | 5.7.40 |
一、加入相关依赖
<dependency>
<groupId>com.baomidou</groupId>
<artifactId>mybatis-plus-boot-starter</artifactId>
<version>3.5.3.1</version>
</dependency>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.49</version>
</dependency>
二、修改application.properties配置
数据库使用了8.x以上的版本驱动为com.mysql.cj.jdbc.Driver
server.port=8001
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/my_demo?useSSL=false&serverTimezone=GMT%2B8
spring.datasource.username=root
spring.datasource.password=123456
三、快速开始
先来看一下整体项目目录结构：
下面开始上代码。
1、创建测试表
CREATE TABLE `game_users` (
`id` varchar(64) NOT NULL,
`user_name` varchar(50) NOT NULL,
`password` varchar(50) NOT NULL,
`email` varchar(50) NOT NULL,
`score` int(11) DEFAULT '0',
PRIMARY KEY (`id`)
)
2、cmd
public interface LoginModule {
int cmd = SpringCmdModule.loginCmd;
int register = 0;
int login = 1;
}
3、Action
@Slf4j
@Component
@ActionController(LoginModule.cmd)
public class UserAction {
@Resource
UserService userService;
@ActionMethod(LoginModule.register)
public String createUser(User user) {
return userService.createUser(user);
}
}
4、实体类
@Data
@ToString
@ProtobufClass
@FieldDefaults(level = AccessLevel.PUBLIC)
public class User {
String id;
String userName;
String password;
String email;
}
5、Mapper
@Mapper
public interface UserMapper extends BaseMapper<User> {
void createUser(User user);
}
xml：
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.io.game.login.mapper.UserMapper">
<insert id="createUser">
insert into game_users (id, user_name, password, email)
values (#{id}, #{userName}, #{password}, #{email});
</insert>
</mapper>
6、Service
public interface UserService extends IService<User> {
String createUser(User user);
}
service实现类：
@Service
public class UserServiceImpl extends ServiceImpl<UserMapper, User> implements UserService {
@Resource
UserMapper userMapper;
@Override
public String createUser(User user) {
user.setId(UUID.randomUUID().toString());
userMapper.createUser(user);
return user.getId();
}
}
7、逻辑服
@Getter
@Setter
@FieldDefaults(level = AccessLevel.PRIVATE)
public class GameLoginClient extends AbstractBrokerClientStartup {
@Override
public BarSkeleton createBarSkeleton() {
// 业务框架构建器 配置
BarSkeletonBuilderParamConfig config = MyBarSkeletonConfig.createBarSkeletonBuilderParamConfig()
// 扫描 action 类所在包
.scanActionPackage(UserAction.class);
// 业务框架构建器
BarSkeletonBuilder builder = MyBarSkeletonConfig.createBarSkeletonBuilder(config);
// 开启 jsr380 验证
builder.getSetting().setValidator(true);
return builder.build();
}
@Override
public BrokerClientBuilder createBrokerClientBuilder() {
BrokerClientBuilder builder = BrokerClient.newBuilder();
builder.appName("spring login 登录游戏逻辑服");
return builder;
}
}
8、启动类
启动类设置了json编解码。
@MapperScan("com.io.game.login.mapper")
@ComponentScan("com.io.game.login")
@SpringBootApplication
public class LoginApplication {
public static void main(String[] args) {
// 设置 json 编解码。如果不设置，默认为 jprotobuf
IoGameGlobalSetting.me().setDataCodec(new JsonDataCodec());
// 启动 spring boot
SpringApplication.run(LoginApplication.class, args);
// 启动班级逻辑服
GameLoginClient gameLogicClient = new GameLoginClient();
BrokerClientApplication.start(gameLogicClient);
}
@Bean
public ActionFactoryBeanForSpring actionFactoryBean() {
// 将业务框架交给 spring 管理
return ActionFactoryBeanForSpring.me();
}
}
注意：
因为我的启动类不和项目在一个模块，需要加上@ComponentScan(“com.io.game.login”)注解，不然会报 No qualifying bean of type ‘com.io.game.login.action.UserAction’ available 错误提示。
13:31:34.847 ERROR [uestMessage-8-2] .game.common.kit.log.IoGameLoggerFactory.handler(ActionCommandTryHandler.java:44) : No qualifying bean of type 'com.io.game.login.action.UserAction' available

以及@MapperScan(“com.io.game.login.mapper”)注解，不加会提示找不到mapper。

四、测试
前端我使用的是uniapp框架（打算做一个h5小游戏），使用Vue3+js编写的一个简陋页面（由于本人主要做后端的，前端不是很熟悉，可能会有错误的地方，欢迎大家指正）
先看下前端整体项目目录结构：
用户注册页面：
<template>
<view>
<input type="text" v-model="username" placeholder="Username" />
<input type="password" v-model="password" placeholder="Password" />
<input type="email" v-model="email" placeholder="Email" />
<button @click="register">Register</button>
</view>
<view id="output" style="margin-top:20px;border: 1px #ddd solid; height: 260px; overflow-y: auto;" />
</template>
<script>
import webSocket from '@/server/websocket.js';
const websocket = webSocket.addsocket("127.0.0.1:10100/websocket")
export default {
data() {
return {
username: "",
password: "",
email: "",
};
},
methods: {
register() {
const data = {
"username": this.username,
"password": this.password,
"email": this.email
}
var message = {
cmdCode: 1,
cmd: 6,
subCmd: 0,
data: data
}
webSocket.SendMessage(message)
},
},
};
</script>
websocket.js
发送消息最主要的方法是createExternalMessage，因为前后端通信使用的json编解码。
import $ from 'jquery'
function formatDate(now) {
var year = now.getFullYear();
var month = now.getMonth() + 1;
var date = now.getDate();
var hour = now.getHours();
var minute = now.getMinutes();
var second = now.getSeconds();
return year + "-" + (month = month < 10 ? ("0" + month) : month) + "-" + (date = date < 10 ? ("0" + date) : date) + " " + (hour = hour < 10 ? ("0" + hour) : hour) + ":" + (minute = minute < 10 ? ("0" + minute) : minute) + ":" + (second = second < 10 ? ("0" + second) : second);
}
var websocket;
function addsocket(addr) {
var wsaddr = "ws://" + addr;
StartWebSocket(wsaddr);
}
function StartWebSocket(wsUri) {
websocket = new WebSocket(wsUri);
websocket.binaryType = 'arraybuffer';
websocket.onopen = function (evt) {
onOpen(evt, wsUri)
};
websocket.onclose = function (evt) {
onClose(evt)
};
websocket.onmessage = function (evt) {
onMessage(evt)
};
websocket.onerror = function (evt) {
onError(evt)
};
}
function onOpen(evt, wsUri) {
writeToScreen("<span style='color:red'>连接成功，现在你可以发送信息进行测试了！</span>");
writeToScreen(wsUri);
}
function onClose(evt) {
writeToScreen("<span style='color:red'>Websocket连接已断开！</span>");
websocket.close();
}
function binaryData(data) {
if (data != null) {
return JSON.parse(new TextDecoder("utf-8").decode(new Uint8Array(data)))
}
}
function onMessage(evt) {
let externalMessage = binaryData(evt.data);
let bizData = externalMessage.data;
let bizDataJson = binaryData(bizData);
externalMessage.data = bizDataJson;
let json = JSON.stringify(externalMessage);
writeToScreen('<span style="color:blue">服务端回应 ' + formatDate(new Date()) + '</span><br/><span>' + json + '</span>');
}
function onError(evt) {
writeToScreen('<span style="color: red;">发生错误:</span> ' + evt.data);
}
function SendMessage(data) {
var externalMessageBytes = createExternalMessage(data);
websocket.send(externalMessageBytes);
}
function createExternalMessage(data) {
if (data != null) {
console.log(data.data)
var message = {
cmdCode: data.cmdCode,
cmdMerge: mergeCmd(data.cmd, data.subCmd),
data: data.data
}
var json = JSON.stringify(message);
writeToScreen('<span style="color:green">你发送的信息 ' + formatDate(new Date()) + '</span><br/>' + json);
var textEncoder = new TextEncoder();
var dataArray = textEncoder.encode(JSON.stringify(data.data));
message.data = Array.from(dataArray);
json = JSON.stringify(message);
return textEncoder.encode(json);
}
}
function writeToScreen(message) {
var div = "<div>" + message + "</div>";
var d = $("#output");
var d = d[0];
var doScroll = d.scrollTop == d.scrollHeight - d.clientHeight;
$("#output").append(div);
if (doScroll) {
d.scrollTop = d.scrollHeight - d.clientHeight;
}
}
function mergeCmd(cmd,subCmd) {
return (cmd << 16) + subCmd;
}
export default {
addsocket,
SendMessage,
websocket
};
页面路由pages.json：
{
"pages": [ //pages数组中第一项表示应用启动页，参考：https://uniapp.dcloud.io/collocation/pages
{
"path": "pages/index/index",
"style": {
"navigationBarTitleText": "uni-app"
}
},
{
"path" : "pages/user/login",
"style" :
{
"navigationBarTitleText": "",
"enablePullDownRefresh": false
}
},
{
"path" : "pages/user/register",
"style" :
{
"navigationBarTitleText": "",
"enablePullDownRefresh": false
}
}
],
"globalStyle": {
"navigationBarTextStyle": "black",
"navigationBarTitleText": "uni-app",
"navigationBarBackgroundColor": "#F8F8F8",
"backgroundColor": "#F8F8F8"
},
"uniIdRouter": {}
}
服务端项目启动：
注意：
服务端需要启动对外服通过websocket与前端建立连接，本次项目为了方便，使用了iogame示例spring项目，一键启动的方式（包括对外服，网关，逻辑服），并另外启动我们的登录逻辑服接入。
前端项目启动：
在页面输入账号密码进行测试：
打开http://localhost:5173/#/user/register,或者在前端HbuildX内置浏览器测试。
查看服务端框架输出日志：
查看数据库是否插入数据：
数据成功插入，至此就圆满结束了！
踩坑记录：
一开始配置文件使用applicaton.yml
spring:
datasource:
driver-class-name: com.mysql.jdbc.Driver
url: jdbc:mysql://localhost:3306/my_demo?useUnicode=true&characterEncoding=UTF-8&serverTimezone=Asia/Shanghai
username: root
password: 123456
application:
name: demo
mybatis-plus:
# 数据库映射实体类包路径
type-aliases-package: com.io.game.login.mapper
mapper-locations: classpath:/mapper/*.xml
configuration:
# 是否开启自动驼峰命名规则（camel case）映射，即从经典数据库列名 A_COLUMN（下划线命名） 到经典 Java 属性名 aColumn（驼峰命名） 的类似映射
map-underscore-to-camel-case: true
但是不知道为啥springboot读取不到配置文件，启动项目会报错。

Description:
Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured.
Reason: Failed to determine a suitable driver class
Action:
Consider the following:
If you want an embedded database (H2, HSQL or Derby), please put it on the classpath.
If you have database settings to be loaded from a particular profile you may need to activate it (no profiles are currently active).

在网上百度了好久，报错的原因是使用了mybatis相关的数据库依赖，但是没有读取到配置文件。解决方法是@SpringBootApplication(exclude = DataSourceAutoConfiguration.class)注解加上exclude = DataSourceAutoConfiguration.class才可以正常启动。
后面尝试使用application.properties配置文件，可以不需要加exclude = DataSourceAutoConfiguration.class，能正常读取到配置并启动。
