Spring Boot Security Application - Bartosz Kielczewski

Well, of course it's quite complicated when you look at it, as its scope covers a lot of use-cases. Thing is that, truly in a Spring spirit, you don't have to use every feature there is at once for the use-case you are having. In fact, when you start cherry-picking and back it with Spring Boot, it doesn't appear so complicated anymore. Let's start with the use case, I was thinking on something relatively common, something that appears in almost every project with some basic access restrictions. So, the requirements of such an app could be: The app will have users, each with role Admin or User They log in by their emails and passwords Non-admin users can view their info, but cannot peek at other users Admin users can list and view all the users, and create new ones as well Customized form for login "Remember me" authentication for lazies Possibility to logout Home page will be available for everyone, authenticated or not.

@Conditional de Spring 4 au coeur de l’auto-configuration de Spring Boot. Spring Boot fournit plusieurs services facilitant la mise en oeuvre et l’exécution d’applications Spring.

@Conditional de Spring 4 au coeur de l’auto-configuration de Spring Boot

Parmi ces principales caractéristiques, on peut mettre en avant : Les possibilités d’auto-configuration sont particulièrement puissantes : Le module autoconfigure est capable d’ajouter “auto-magiquement” les beans d’infrastructure nécessaires à votre application : une datasource, un transaction manager, une entity manager factory JPA, tous le trains de beans nécessaires à Spring MVC, un tomcat ou jetty embarqué, etc… (la liste est longue) Le tout configuré avec des valeurs par défauts adéquates.

Si ces défauts ne vous conviennent pas : une bonne partie des valeurs sont paramétrables via des propriétés et sinon, il vous suffit de définir vous même le bean en question : Spring Boot le détectera et gardera votre définition. Spring Boot utilise et combine plusieurs stratégies pour décider s’il doit ou non définir un bean : Et voici l’implémentation de Condition associée : ... Spring Boot and Spring Data REST - exposing repositories over REST ~

Exposing Spring Data repositories over REST is pretty easy with Spring Boot and Spring Data REST.

Spring Boot and Spring Data REST - exposing repositories over REST ~

With minimal code one can create REST representations of JPA entities that follow the HATEOAS principle. I decided to re-use Spring PetClinic’s JPA entities (business layer) as the foundation for this article. Application foundation The PetClinic’s model is relatively simple, but it consist of some unidirectional and bi-directional associations, as well as basic inheritance: In addition, the Spring’s PetClinic provides SQL scripts for HSQLDB which makes that generating schema and populating it with sample data in my new application was super easy. Introduction to Spring Data JPA. Table of Contents 1.

Introduction to Spring Data JPA

Overview This article will focus on introducing Spring Data JPA into a Spring 4 project and fully configuring the persistence layer. For a step by step introduction about setting up the Spring context using Java based configuration and the basic Maven pom for the project, see this article. 2. As discussed in an earlier article, the DAO layer usually consists of a lot of boilerplate code that can and should be simplified.

Spring Data takes this simplification one step forward and makes it possible to remove the DAO implementations entirely – the interface of the DAO is now the only artifact that need to be explicitly defined. In order to start leveraging the Spring Data programming model with JPA, a DAO interface needs to extend the JPA specific Repository interface – JpaRepository. By extending the interface we get the most relevant CRUD methods for standard data access available in a standard DAO out of the box. Properties with Spring. Table of Contents 1.

Properties with Spring

Framework 4.0 M1: WebSocket Support

Why WebSocket matters? It enables efficient, two-way communication over the web that is essential in applications where messages need to be exchanged between client (typically browser) and server at high frequency and with low latency. Introducing Spring MVC test framework. Spring MVC comes with a very useful test framework, which allows doing in-depth testing without even starting a web container.

Introducing Spring MVC test framework

If you struggle maintaining any application based on Spring MVC, this post will show you the basics of the Spring MVC test framework. What am I testing? REST in Spring 3: RestTemplate. In an earlier post, I blogged about the REST capabilities we added to Spring @MVC version 3.0.

REST in Spring 3: RestTemplate

Later, Alef wrote about using the introduced functionality to add an Atom view to the Pet Clinic application. In this post, I would like to introduce the client-side capabilities we added in Milestone 2. RestTemplate The RestTemplate is the central Spring class for client-side HTTP access. Conceptually, it is very similar to the JdbcTemplate, JmsTemplate, and the various other templates found in the Spring Framework and other portfolio projects.

RestTemplate Methods The main entry points of the template are named after the six main HTTP methods: The names of these methods clearly indicate which HTTP method they invoke, while the second part of the name indicates what is returned. REST. Spring Security Reference. Spring Security is a powerful and highly customizable authentication and access-control framework. It is the de-facto standard for securing Spring-based applications. Spring Security provides a comprehensive security solution for Java EE-based enterprise software applications. As you will discover as you venture through this reference guide, we have tried to provide you a useful and highly configurable security system. Security is an ever-moving target, and it’s important to pursue a comprehensive, system-wide approach.

In security circles we encourage you to adopt "layers of security", so that each layer tries to be as secure as possible in its own right, with successive layers providing additional security. Of course, you will need to properly address all security layers mentioned above, together with managerial factors that encompass every layer. Please read Getting Started, in its entirety to begin with. Spring MVC Tutorial. Spring Security Tutorial. Spring Object/XML mapping example. The Spring’s Object/XML Mapping, is converting Object to XML or vice verse. This process is also known as XML Marshalling – Convert Object to XML.XML UnMarshalling – Convert XML to Object. In this tutorial, we show you how to use Spring’s oxm to do the conversion, Object <--- Spring oxm ---> XML.

Spring Security HTTP basic authentication example. When HTTP basic authentication is configured, web browser will display a login dialog for user authentication. This tutorial show you how to configure HTTP basic authentication in Spring Security. Last Spring Security form-based login example will be reused, but switch authentication to support HTTP basic. 1. Spring Security To enable HTTP basic, just change “form-login” to “http-basic” tag. Done, that’s all. How to create a Web Application Project with Maven.
