背景：

之前一直只考虑用JavaSe进行游戏服务器开发，目前项目使用了Spring，发现还是非常好的，好处如下:

好处1:依赖注入非常方便，我们只使用Spring最基本的功能即可，这样子就算是有一些模块不使用Spring管理也是非常方便的，因为我现在已经能轻松控制住Spring容器的声明周期。

好处2: 模块之间就像搭建积木即可，又相互配合。我想支持web也是非常轻松。

好处3: 这样子再去整合Mybatis、或者其它的一些MQ、ES之类的中间件，就太简单了。

pom.xml // 项目中使用了lettuce，这里作为演示

       <dependency><groupId>io.lettuce</groupId><artifactId>lettuce-core</artifactId><version>5.1.8.RELEASE</version></dependency><dependency><groupId>com.alibaba</groupId><artifactId>fastjson</artifactId><!--（起码1.2.48以上）因为这个版本一下存在漏洞--><version>1.2.48</version></dependency>

1.Application.java

package com.example.springbootgame.application;import org.springframework.context.ApplicationContext;public class Application {private static ApplicationContext applicationContext;public static ApplicationContext getApplicationContext() {return applicationContext;}public static void setApplicationContext(ApplicationContext applicationContext) {Application.applicationContext = applicationContext;}public static <T> T getBean(Class<T> requiredType) {if (applicationContext == null) {return null;}return applicationContext.getBean(requiredType);}}

2.RedisConfig.java // 使用Configuration引入一些自定义的Bean

package com.example.springbootgame.config;import io.lettuce.core.RedisClient;
import io.lettuce.core.RedisURI;
import io.lettuce.core.api.sync.RedisCommands;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;import java.time.Duration;
import java.time.temporal.ChronoUnit;@Configuration
public class RedisConfig {@Beanpublic GameRedis getGameRedis() {RedisURI redisURI = RedisURI.builder().withHost("localhost").withPort(6379).withTimeout(Duration.of(10, ChronoUnit.SECONDS)).build();RedisClient redisClient = RedisClient.create(redisURI);return new GameRedis(redisClient.connect().sync());}
}

3.GameRedis.java // 包装器模式。包装出自己的访问接口

package com.example.springbootgame.config;import io.lettuce.core.api.sync.RedisCommands;public class GameRedis {private RedisCommands redisCommands;public GameRedis(RedisCommands redisCommands) {this.redisCommands = redisCommands;}public <K, V> V get(K k) {return (V) redisCommands.get(k);}public <K, V> void set(K k, V v) {redisCommands.set(k, v);}
}

4.LoginHandler.java

package com.example.springbootgame.handler;import com.alibaba.fastjson.JSON;
import com.example.springbootgame.config.GameRedis;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;import java.util.HashMap;
import java.util.Map;@Controller
public class LoginHandler {@AutowiredGameRedis gameRedis;/*** 玩家登录*/public void onCSLogin() {// 简单类型gameRedis.set("123", "abc");String v = gameRedis.get("123");System.out.println(v);// 复杂类型Data data = new Data();data.map.put("k", 6666);gameRedis.set("obj", JSON.toJSONString(data));Data obj = JSON.parseObject(gameRedis.get("obj"), Data.class);System.out.println(obj);}private static class Data {public int num = 1;public Map<String, Integer> map = new HashMap<>();@Overridepublic String toString() {return "Data{" +"num=" + num +", map=" + map +'}';}}
}

5.GameServer.java

package com.example.springbootgame;import com.example.springbootgame.application.Application;
import com.example.springbootgame.handler.LoginHandler;
import lombok.extern.slf4j.Slf4j;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ConfigurableApplicationContext;import java.io.IOException;@SpringBootApplication
@Slf4j
public class GameServer {public static void registerShutdownHook() {Runtime.getRuntime().addShutdownHook(new Thread(() -> {log.info("gs shutdown in {}", Thread.currentThread().getName());// 测试bean的获取LoginHandler loginHandler = Application.getBean(LoginHandler.class);loginHandler.onCSLogin();// 关闭Spring容器ApplicationContext applicationContext = Application.getApplicationContext();if (applicationContext != null) {ConfigurableApplicationContext cac = (ConfigurableApplicationContext) applicationContext;cac.close();}}, "ShutdownHook-GameServer-Thread"));}public static void main(String[] args) {registerShutdownHook();// 启动Spring容器ApplicationContext applicationContext = SpringApplication.run(GameServer.class, args);Application.setApplicationContext(applicationContext);// 初始化各个模块,如:进行handler的扫描// 阻塞关服try {System.in.read();} catch (IOException e) {log.error("exception", e);}}}
