ring VS Hibernate

* HTTP: Ring is the de facto way to manage HTTP request (see https://github.com/ring-clojure/ring/wiki/Concepts). Jetty and Aleph are common web servers (and https://github.com/clj-commons/aleph) that implement Ring interface.

> In the HTTP handlers it makes sense that you don't have return values, because: What would you do with that value exactly?

I think that approach used by clojure's ring shows an elegant way to represent http responses https://github.com/ring-clojure/ring/wiki/Concepts#responses. They are essentially structs with the following fields:

status := number

headers := map of string->string

body := stream | string | seq | inputstream

Request handlers are handed a request struct that is similar. The handler is a function that maps a request to a response (it doesn't actually write to streams itself).

I like this style for an http library for a couple of reasons:

1. HTTP resources can be viewed as functions whose domain is the request, and range is the response. Having the abstraction match that makes for really nice code.

While you won't find your Spring here, you will find that many of those web libraries will tend to use or produce Hiccup, return Ring maps or maybe have pipelines built using interceptors. Composing libraries together is usually not that hard, but it does require you to leave the comfort zone of the framework's abstractions to try to understand what is actually happening e.g. when someone makes an HTTP request and something is returned and displayed in the browser.

On that note, are you able to support everything required by the ring spec?

You can check out my example project in Clojure with using Ring.

It uses already mentioned ring api (https://github.com/ring-clojure/ring/wiki).

I've tried to pair down to the simplest example which shows the issue, and raised it here as I couldn't see one you'd already created or similar: https://github.com/ring-clojure/ring/issues/436 This is so that I have something to link to/follow from our side, hope you don't mind, and many thanks for the diagnosis!

And Hibernate ORM is LGPL: see the license on their Github project.

13. Hibernate

Hibernate is the umbrella for a collection of libraries, most notably Hibernate ORM which provides Object/Relational Mapping for java domain objects. In addition to its own "native" API, Hibernate ORM is also an implementation of the Java Persistence API (jpa) specification.

I'm using Spring Data JPA as a persistence framework. Therefore, those classes are Hibernate entities.

Hibernate -- https://hibernate.org (huge learning curve)

This video is a crash course into the Hibernate & JPA universe.

To prevent SQL Injection attacks to sanitize input data. You can either validate every single input or validate using parameter binding. Parameter binding is mostly used by developers as it offers efficiency and security. If you are using a popular ORM such as sequelize, hibernate, etc then they already provide the functions to validate and sanitize your data. If you are using database modules other than ORM such as mysql for Node or Mongoose, you can use the escaping methods provided by the module. Let's learn by example. The codebase shown below is using mysql module for Node.
