Spring boot IntroductionJeevesh PandeyThe document provides an overview of Spring Boot, detailing its key features such as rapid prototyping, dependency management, and production-ready capabilities without the need for extensive configuration. It highlights the framework's ease of use, the support for various build tools like Gradle and Maven, and its integration with Spring Data libraries. Additionally, examples of setting up applications, managing profiles, and utilizing built-in features such as security and health checks are discussed.
jpa-hibernate-presentationJohn SlickThe document discusses Java Persistence API (JPA) and Hibernate, which are frameworks that help map objects to relational databases and resolve the impedance mismatch between object-oriented and relational models. JPA is a specification that providers like Hibernate implement. Hibernate is an object/relational mapping tool that provides object/relational mapping, object/relational persistence services, and query capabilities. It generates database schemas from object models and vice versa. The document also provides examples of performing basic CRUD operations using JPA and SQL.
Introduction à spring bootAntoine ReyCe document présente Spring Boot, mettant en avant ses avantages tels que l'accélération du développement d'applications Java avec une configuration simplifiée et sans code généré. Il aborde également l'auto-configuration, les tests simplifiés et propose des exemples pratiques d'applications. Enfin, il souligne la transition vers Spring Boot en tant que solution prête pour la production, remplaçant les serveurs d'applications traditionnels.
Spring Data JPA from 0-100 in 60 minutesVMware TanzuThe document provides an overview of Spring Data JPA, covering its basic features such as CRUD operations, query derivation, pagination, and specifications. It includes code examples demonstrating how to use Spring Data JPA to manage entities and perform database operations. Additional information on Spring Data JDBC is also mentioned as an alternative to Spring Data JPA.
Spring data jpaJeevesh PandeyThe document provides an overview of Spring Data JPA, highlighting its features such as repository abstractions, entity management, and support for various database systems. It covers essential concepts like entity configuration, relationships, inheritance, and query methods. Additionally, it outlines potential drawbacks and offers references for further exploration of Spring Data JPA.
react redux.pdfKnoldus Inc.The document presents an introduction to React-Redux, emphasizing the importance of etiquette in sessions, including punctuality and feedback. It covers the architecture of modern web applications, highlighting state management and the benefits of using Redux for centralized data handling. Additionally, it explains how Redux works with React through views, actions, reducers, and selectors, showcasing its advantages like predictability and debuggability.
Hibernate Presentationguest11106bHibernate is an object-relational mapping tool for Java that allows developers to persist Java objects to a relational database in a transparent way. It provides transparent persistence without needing to flatten objects or write database specific code. Hibernate uses an object-oriented query language that closely resembles SQL to retrieve and manipulate persisted objects.
React + Redux IntroductionNikolaus GrafThe document provides a comprehensive introduction to React and Redux, covering key concepts such as the virtual DOM, JSX syntax, and component rendering. It details the creation and management of state through Redux, including actions and reducers, while emphasizing the benefits of predictable and reusable components. Additionally, it highlights real-world usage and the popularity of these technologies among major companies.
Hibernate architectureAnurag Hibernate has several core framework objects that represent the different components of the architecture. The SessionFactory acts as a factory for Session objects and caches compiled object mappings. Each Session represents a single-threaded conversation with the database and manages a level one cache and transactions. Persistent objects are associated with a Session and represent the data model, while transient and detached objects are not associated with a Session. Transactions demarcate atomic units of work and are represented by the Transaction object. The ConnectionProvider manages connections to the database and abstracts the application from the underlying data source.
Spring CorePushan BhattacharyaThe document provides an in-depth overview of the Spring Framework, focusing on concepts such as dependency injection, bean lifecycle, and bean scopes. It explains techniques including constructor and setter injection while highlighting the differences between singleton and prototype bean scopes. Additionally, the document details how to implement various features of Spring through XML configuration and provides code examples demonstrating these concepts in action.
Node.js ExpressEyal VardiThe document discusses Node.js and Express.js concepts for building web servers and applications. It includes examples of creating HTTP servers, routing requests, using middleware, handling errors, templating with views and layouts, and separating code into models and routes.
Introduction to JWT and How to integrate with Spring SecurityBruno Henrique RotherThe document discusses JSON Web Tokens (JWT) and their integration with Spring Security for secure authentication and authorization. JWTs are compact and self-contained tokens used for transmitting information securely, which can be verified through digital signatures. Spring Security is a framework that extends authentication and authorization capabilities, and it can be configured to support JWT for stateless authentication in applications.
Mongoose and MongoDB 101Will ButtonThis document provides a summary of MongoDB and Mongoose 101 presented at a Phoenix MongoDB Meetup. It introduces the presenter and his background. It then provides a high-level overview of MongoDB and compares SQL and MongoDB terminology. The remainder of the document demonstrates basic CRUD operations in MongoDB using the Mongo shell and introduces Mongoose, an ORM for MongoDB, demonstrating how to define schemas and models and perform queries and validations. It also discusses subdocuments and population features in Mongoose.
Spring bootsdeegThis document contains an agenda and slides for a presentation on Spring Boot. The presentation introduces Spring Boot, which allows developers to rapidly build production-grade Spring applications with minimal configuration. It demonstrates how to quickly create a "Hello World" application using Spring Boot and discusses some of the features it provides out-of-the-box like embedded servers and externalized configuration. The presentation also shows how to add additional functionality like Thymeleaf templates and actuator endpoints to monitor and manage applications.
Java 8-streams-collectors-patternsJosé PaumardLe document traite des concepts de streams et des collecteurs en Java 8, expliquant comment ils permettent de traiter efficacement des volumes de données. Il discute de la définition d'un stream, de ses opérations, et des patterns pour les construire, tout en abordant des points techniques sur les interfaces fonctionnelles et la gestion de la concurrence. Enfin, il aborde des détails sur l'utilisation des consommateurs et des prédicats, offrant des exemples pratiques d'application.
Java Hibernate Programming with Architecture Diagram and Examplekamal kotechaHibernate is an open-source object-relational mapping tool for Java that simplifies database interaction by allowing developers to work with plain old Java objects (POJOs) instead of SQL. It features a three-component architecture encompassing connection management, transaction management, and object-relational mapping to efficiently manipulate data in a relational database. Hibernate is well-suited for applications with complex data models and can be configured to support various database types through specific dialects.
