netty案例,netty4.1中级拓展篇一《Netty与SpringBoot整合》

前言介绍

在实际的开发中,我们需要对netty服务进行更多的操作,包括;获取它的状态信息、启动/停止、对客户端用户强制下线等等,为此我们需要把netty服务加入到web系统中,那么本章节介绍如何将Netty与SpringBoot整合。

Spring Boot是由Pivotal团队提供的全新框架,其设计目的是用来简化新Spring应用的初始搭建以及开发过程。该框架使用了特定的方式来进行配置,从而使开发人员不再需要定义样板化的配置。通过这种方式,Spring Boot致力于在蓬勃发展的快速应用开发领域(rapid application development)成为领导者。

开发环境

1、jdk1.8【jdk1.7以下只能部分支持netty】
2、Netty4.1.36.Final【netty3.x 4.x 5每次的变化较大,接口类名也随着变化】
