Simple HTTP server written in Java and packaged within just one JAR file.
- Multiple parallel connections
- Persistent connections
- Range requests
- Directory indexes
- Basic access authentication
- Support for If-Modified-Since requests
- Support for tiny url style path aliases
Running the server is very easy. The bare minimum is:
HttpServer httpServer = new HttpServer.Builder().build();
httpServer.startServer();This starts up with the defaults, most importantly using /tmp as the page root and 10001 as the port to listen on.
As you might expect, stopping the server is:
httpServer.stopServer();The snippet below shows an example using all of the available configuration options.
HttpServer httpServer = new HttpServer.Builder()
.setPageRoot("/tmp")
.setPortNumber(10001)
.setMaxParallelConnections(10)
.setAllowDirectoryIndexes(true)
.setBasicAccessAuthentication(new BasicAccessAuthentication("realm", "username", "password"))
.addWelcomeFile("index.html")
.addContentType("mp4", "video/mp4")
.addAlias("/abc", "/index.html")
.setAllowOnlyAliases(true)
.build();The package includes an interactive stand-alone shell, which can be used to test the server for example from a console.
Running the shell:
$ java -cp embedded-http-server-0.0.1.jar com/tt/embeddedhttpserver/HttpServer

start
[INFO ] 06.01.15 09:15:36 accepting connections on port 10001
[INFO ] 06.01.15 09:15:36 client executor service created
Stopping the server:
stop

[INFO ] 06.01.15 09:16:00 client executor service shut down
Exiting the shell:
quit
It is possible to define short aliases for longer urls, for example:
httpServer.addAlias("/abc", "/some/other/longer/path/awesome.html");
This makes the server translate the request path before other processing, so it is not a redirect for example. Note also that the alias is a key in a map, so adding one that already exists effectively overwrites the previous.
You can also choose to allow only aliases to be processed:
httpServer.setAllowOnlyAliases(true);
Now, if the alias is not found, a HTTP 404 will be returned.
