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 dependencygroupIdio.lettuce/groupIdartifactIdlettuce-core/artifactIdversion5.1.8.RELEASE/version/dependencydependencygroupIdcom.alibaba/groupIdartifactIdfastjson/artifactId!--起码1.2.48以上因为这个版本一下存在漏洞--version1.2.48/version/dependency 1.Application.java
