This tutorial demonstrates how to set up Elasticsearch 7.6 with the IK analyzer, import Spring Data Elasticsearch dependencies, configure connection beans, define entity and repository classes, and implement CRUD, pagination, and highlighted search operations in a Spring Boot application.
This tutorial demonstrates how to set up Elasticsearch 7.6 with the IK analyzer in a Spring Boot 2.3 project, import the appropriate Spring Data Elasticsearch dependency, configure the client, define indexed entity classes, create repository interfaces, and implement REST controllers for CRUD, pagination, and highlighted search queries, complete with code examples and test results.
This article explains how to parse user‑defined query strings and convert them into type‑safe Spring Data Querydsl predicates, covering query patterns, code examples, dynamic query building, and handling complex parent‑child relationships in backend services.
This guide walks through configuring custom and multiple data sources, using Spring Data repositories, fine‑tuning JPA and Hibernate settings, customizing naming strategies, enabling second‑level caching, and exposing repositories as REST endpoints in a Spring Boot 2.4.13 application.
Microservice architecture introduces complexity, but using scaffolding tools such as Spring Boot and Spring Data lets developers focus on business logic by providing reusable components, reducing duplication, and simplifying data access, while avoiding the pitfalls of building custom persistence layers from scratch.
The article explains the concept of software scaffolding, why it is needed for microservice development, outlines key design principles, shares a real‑world case of replacing a custom persistence layer with Spring Data, and reviews popular scaffolding tools such as Vue CLI, Maven, Netty, Java EE, Dropwizard and Spring Boot.
This tutorial explains how to set up a single‑node Elasticsearch instance with Docker, integrate it into a Spring Boot application using Spring Data Elasticsearch Repositories, configure the necessary dependencies and settings, and perform basic CRUD operations and visualization with Kibana.
An in‑depth comparison of popular Java DAO frameworks—including JDBC, JOOQ, MyBatis, Hibernate, and Spring Data—covers their core concepts, code examples, ideal use cases, and limitations, helping developers choose the most suitable data‑access layer for their projects.
This tutorial walks you through upgrading Spring Boot, introduces MongoDB basics, and provides a hands‑by‑step guide to adding the spring‑boot‑starter‑data‑mongodb dependency, defining entity and repository classes, writing unit tests, and configuring connection properties for robust backend data management.
