Jetty HTTP2 server/client demo

This demo shows capabilities of Jetty server, Servlet 4.0 APIs and Http2. Services deployed in this demo are accessible via HTT1.1 and HTTP2.

Architecture

  • client layer - in this demo it is implemented as TestNG integration tests. See package itx.examples.jetty.client.* and TestNG client tests in itx.examples.jetty.tests.*
  • transport layer - jetty is started with two connectors (http1.1 and http2). Http 1.1 communication may use secure and non-secure transport. Http2 uses only secure transport. See itx.examples.jetty.server.ServerBuilder
  • web layer - uses servlets and stream processors to access services below. Servlets are implemented in itx.examples.jetty.server.servlet.* and stream processors are implemented in itx.examples.jetty.server.streams.* Stream processors are used for full-duplex communication between client and server.
  • service layer - implements some demo services, so there are data available for testing. Services must be thread-safe, because they are accessed from concurrent clients. See itx.examples.jetty.server.services.*.

Server URLs:

http://localhost:8080/static/index.html
https://localhost:8443/static/index.html

GET HTTP 1.1 http://localhost:8080/data/system/info
GET HTTP 2.0 https://localhost:8443/data/system/info

GET HTTP 1.1 http://localhost:8080/data/echo/helloworld
GET HTTP 2.0 https://localhost:8443/data/echo/helloworld

See also attached postman file.

TODO

Http2 stream full-duplex communication is not fully implemented for MassageService.

Build and Run

Build from commandline:

gradle clean build installDist distZip

Run server:

./build/install/jetty-servlet4-http2/bin/jetty-servlet4-http2

Run Integration Tests

Integration tests in this demo are designed to run as http client against running server instance. It is expected that server runs on localhost, ports 8080 for http and 8443 for https. Follow this procedure to run integration tests:

  1. Start server manually in new terminal window.
./build/install/jetty-servlet4-http2/bin/jetty-servlet4-http2
  1. Start unit integration tests in new terminal window.
gradle clean test -Dtest.profile=integration
