這篇文章主要介紹“Netty框架實(shí)現(xiàn)TCP/IP通信的詳細(xì)過程”，在日常操作中，相信很多人在Netty框架實(shí)現(xiàn)TCP/IP通信的詳細(xì)過程問題上存在疑惑，小編查閱了各式資料，整理出簡(jiǎn)單好用的操作方法，希望對(duì)大家解答”Netty框架實(shí)現(xiàn)TCP/IP通信的詳細(xì)過程”的疑惑有所幫助！接下來，請(qǐng)跟著小編一起來學(xué)習(xí)吧！
項(xiàng)目中需要使用到TCP/IP協(xié)議完成數(shù)據(jù)的發(fā)送與接收。如果只是用以前寫的簡(jiǎn)單的socket套接字方法，每次接收發(fā)送消息都會(huì)創(chuàng)建新的socket再關(guān)閉socket，造成資源浪費(fèi)。于是使用netty框架完成java網(wǎng)絡(luò)通信。
Netty框架的內(nèi)容很多，這里只是代碼展示其中的一個(gè)功能。
代碼倉庫
這里使用的是Springboot+Netty框架，使用maven搭建項(xiàng)目。這里是在一個(gè)項(xiàng)目中搭建服務(wù)端與客戶端，所以端口一樣。還可以使用TCP/UTP工具自己搭建服務(wù)端和客戶端，只要在yml文件中修改ip和端口就好。
