Java NIO simple HTTP server

Overview

A very simple HTTP server that is able to receive GET requests and serve local files. Only HTTP/1.1 is supported.

This project is an educational project.

Built for Java 7+ without any external dependencies. Works in a non-blocking fashion and uses Java NIO and NIO.2 (combines reactor and proactor patterns).

Build

To build the server run:

gradlew build

The built .jar file will be located under build/libs/.

Run

To start the server with default configuration run:

java -jar http-nio-server-1.0.0.jar

You also can override default configuration by specifying the path as a command line argument:

java -jar http-nio-server-1.0.0.jar "/home/settings.properties"

Server configuration

By default tries to read configuration from settings.properties file located in the folder where server executable was run. Falls back to default configuration if the file was not found.

Configuration file must have properties format and must have the following settings:

• port (default: 8080) - server port
• www_root (default: <empty>) - path to the folder containing files that the server will be serving; empty or missing value means the folder where server executable was run
• session_timeout_secs (default: 30) - maximum time in seconds that any connection will be served; connection will be closed when the timeout is reached
• max_connections (default: 10000) - maximum number of simultaneous connections that will be served
