Summary

This book is the Chinese translation of the 4th edition of O'Reilly's classic technical title Java Network Programming, aimed at developers who want to write network programs in Java. It begins with fundamental networking concepts, first laying out network layering, IP/TCP/UDP and the client-server model, then introducing Java's foundational supporting mechanisms such as streams and I/O, threads and thread pools. It then moves into the core of network programming: interacting with DNS via InetAddress, locating and reading network resources with URI, URL and URLConnection, delving into the HTTP protocol (REST style, HTTP headers and cookies), writing network clients and servers with low-level Sockets, implementing encrypted communication with SSLSocket, managing large numbers of concurrent connections with NIO non-blocking I/O, and broadcasting data over the local network via UDP and IP multicast. The author emphasizes "runnable code": the examples come from real working programs, helping readers transfer API usage directly to real projects. The 4th edition has been thoroughly revised, adding then-newer technical content such as REST, SPDY and asynchronous I/O. At about 448 pages and 545,000 characters, the book suits readers who already know Java syntax and want to build a systematic knowledge of network programming through careful study.

Editor's review

在 Java 技术书里,讲语法的书很多,把网络编程讲透的书却不多。《Java网络编程》长期被视为这一领域的经典入门与案头参考:它不满足于罗列 API,而是先把 TCP/IP、客户端—服务器模型、流与线程这些“地基”讲清楚,再带你一层层走到 Socket、HTTP、SSL 与非阻塞 I/O。第4版由李帅、荆涛翻译,中国电力出版社引进 O'Reilly 原版,译文保留了原书示例密集、讲解直给的风格。对国内读者尤其实用的是:书中的例子可以直接编译运行,多线程服务器、加密通信、本地网络广播、向服务端提交数据等场景都能找到对应实现思路,而不是停留在伪代码。需要提醒的是,本版成书于 2014 年,示例以当时的 Java 版本为准,SPDY 等内容后来已被 HTTP/2 取代;但网络分层、Socket、NIO、HTTP 语义这些核心知识并不过时,仍是读框架源码、排查连接问题的基础。把它当作“原理+动手”的第一本网络编程书,性价比很高。

Who it's for

A good fit for

  • 已掌握 Java 基本语法,想系统学习网络编程的开发者
  • 从事后端或中间件开发,需要理解 Socket、NIO、HTTP 底层机制的工程师
  • 计算机相关专业学生,配合课程做网络编程实验与课程设计
  • 习惯通过可运行示例学习、希望边读边动手的实践型读者

Not a good fit for

  • 零编程基础的初学者,书中默认读者熟悉 Java 语言与基本 I/O
  • 想直接学 Spring、Netty 等框架用法而非底层原理的读者
  • 期待覆盖最新 Java 版本与 HTTP/2、HTTP/3 等新特性的读者

Reading tips

  1. 按章节顺序读:先吃透第2、3章的流与线程,再进入第4章以后的地址、URL 与 Socket 部分。
  2. 把书中示例亲手敲一遍或从配套源码运行,改造参数观察连接、超时与并发行为的变化。
  3. 读到 HTTP 和 NIO 章节时,用抓包工具对照真实请求,理解首部、cookie 与连接复用的实际表现。
  4. NOTE 遇到 SPDY 等已过时内容可快速略读,把精力放在 TCP/UDP、Socket、NIO 与 HTTP 语义等长期有效的知识上。

Contents

  1. Chapter 1 Basic Network Concepts: Networks, Network Layering, IP, TCP and UDP, the Internet, the Client/Server Model, Internet Standards

  3. Chapter 3 Threads: Running Threads, Returning Information from Threads, Synchronization, Deadlock, Thread Scheduling, Thread Pools and Executors

FAQ

这本书是第几版,对应原书哪一版?
中文版由中国电力出版社于2014年9月出版,对应 O'Reilly 原书《Java Network Programming》第4版,译者为李帅、荆涛,ISBN 9787512361881,全书448页、约54.5万字。
需要什么基础才能读这本书?
建议先掌握 Java 基本语法、异常处理与多线程基础,并了解输入输出流的基本用法。书中第2、3章会复习流与线程,但节奏较快,完全没有 Java 基础会觉得吃力。
书中的例子能直接运行吗?
书中示例以完整可运行的程序为主,作者强调代码取自实际可用程序。阅读时注意示例基于成书时的 Java 版本,个别 API 在新版 JDK 中可能需要调整,建议边读边编译验证。
2014 年出版的书现在读还不过时吗?
网络分层、TCP/UDP、Socket、NIO、HTTP 语义等核心内容依然有效,是理解框架底层的良好基础;但 SPDY 等具体技术已被取代,新版本 Java 的 API 变化也需自行对照,建议与官方文档配合阅读。
