    Feign

    Make writing Java http clients easier

    Feign is a Java to HTTP client binder that was built primarily to make writing Java http clients easier. Inspired by previous projects Retrofit, JAXRS-2.0 and WebSocket, Feign was designed to reduce the complexity that is often involved in binding the Denominator uniformly to HTTP APIs, no matter the ReSTfulness. Feign works by processing annotations into a templatized request, to which arguments are applied in a straightforward manner before output. While it may only support text-based APIs, it simplifies system aspects dramatically and makes it much easier to unit test your conversions. Feign makes use of great tools like Jersey and CXF for writing Java clients for ReST or SOAP services. It also lets you write your own code on top of http libraries, and connects your code to http APIs with little overhead.

    NanoHTTPD

    NanoHTTPD

    Tiny, easily embeddable HTTP server in Java

    NanoHTTPD is a light-weight HTTP server designed for embedding in other applications, released under a Modified BSD licence. It is being developed at Github and uses Apache Maven for builds & unit testing. Nanolets are like servlets only that they have a extremely low profile. They offer an easy to use system for a more complex server application. We are currently in the process of stabilizing NanoHTTPD from the many pull requests and feature requests that were integrated over the last few months. The next release will come soon, and there will not be any more "intended" major changes before the next release. If you want to use the bleeding edge version, you can clone it from Github, or get it from sonatype.org (see "Maven dependencies / Living on the edge" below). Fully functional HTTP(s) server consisting of one (1) Java file, ready to be customized/inherited for your own project. Simple examples on how to customize NanoHTTPD.

    Milkman

    Milkman

    An extensible request/response workbench

    Milkman is heavily inspired by Postman. But I got sick of all those electron-based applications that need ages and loads of memory to start up. Therefore, this is a JavaFx-based workbench for crafting requests/responses. It is not limited to e.g. HTTP (or more specifically rest) requests. Due to nearly everything being a plugin, other things are possible, like database requests or GRPC, GraphQl, etc. Request-types (e.g. Http Request), request-aspects (e.g. Headers, Body, etc), editors for request aspects (e.g. table-based editors for headers), importers, whatever it is, you can extend it. The core application only handles Workspaces with Environments, Collections, Requests, and their aspects. Several plugins are provided already that extend the core application to be a replacement for postman. Crafting and Executing Http/Rest requests with json highlighting. Support Proxy-server configuration and SSE.

    Takes

    Takes

    True object-oriented Java web framework without NULLs

    Takes is a true object-oriented and immutable Java8 web development framework. Pay attention that UTF-8 encoding is set on the command line. The entire framework relies on your default Java encoding, which is not necessarily UTF-8 by default. To be sure, always set it on the command line with file.encoding Java argument. We decided not to hard-code "UTF-8" in our code mostly because this would be against the entire idea of Java localization, according to which a user always should have a choice of encoding and language selection. We're using Charset.defaultCharset() everywhere in the code. Essential part of Bigger Example is Front interface. It's encapsulates server's back-end and used to start an instance, which will accept requests and return results. FtBasic, which is a basic front, implements that interface.
