(GraphQL, REST, …) Hello again everybody, it’s Süxy here! Today we are going to take a look at several custom implementations for the good old “filterable + sortable + pageable list” problem. In this post we are going to compare the oldschool REST solution with GraphQL and our custom solution (both at the source code level and performance), […]

Introduction Okay so we made a filterable + sortable + pageable list before with Spring + Couchbase (you can read more about it here and here, I totally recommend you read those posts, cuz I’ll refer to them in this one). Actually filters are meant to be in an AND relation between the parameters (most of the cases). […]
Introduction Basically I’ll show you how to use Spring Security and how to customize it if you want. First we’ll implement the basic authentication with basic responses and other stuff, and I’ll show you how to customize the login and logout process as you wish Simple Authentication After you added the required dependencies described on Spring’s website, […]
This post will show you how to connect your Spring application to multiple SQL Databases at the same time. But first, let’s see when multiple DB connections are useful. For example you have an application and you have that application set up in different environments (let’s call it “prod app”), and you want to write […]
CouchbaseQueryExecutor vol2. Welcome back ! In a previous post I wrote about a library I made to dynamically build queries for Couchbase. This dynamic query-building solves the filterable + sortable list problem. Hope you liked that post. In case you didn’t read it, you totally should read it . Today I’m going to introduce the changes I made to that library. […]
Sure it’s not Instagram filters; Couchbase filters are to be created here: What is Couchbase? Couchbase Server is a NoSQL document database with a distributed architecture for performance, scalability, and availability. It enables developers to build applications easier and faster by leveraging the power of SQL with the flexibility of JSON. http://www.couchbase.com/nosql-databases/couchbase-server Why do you […]
What is WebSocket? When should I use it? WebSocket is an amazingly fast, easy to use and full-duplex way to communicate between client and server. WebSocket is recommended if you want a fast real-time application like a bid application, or a real time poker game. It’s easy to broadcast messages between users (or just send […]
This post will tell you how we use a simple YAML file to insert the initial data (like roles, privileges, admin user, and all the other necessary data) into our database. We use Play! Framework (Java) with Hibernate. The important part is how we make Objects from the YAML description using SnakeYAML (Play framework’s integrated YAML parser) though.
I’ll give you some tricks on how to use YAML easily in order to create the initial data for your application.
If you have a website on which users can register and login, then you also want to protect your application from attackers. We recommend you to protect your application’s actions not only from attackers, but from users, too. For example, if you want to make a user who can upload Excel files on a specific UI, then that user should neither see other UIs, nor should s/he be allowed to take any other actions.
