For a One-to-One relationship in JPA, each entity instance is related to a single instance of another entity. It means each row of one entity is referred to one and only one row of another entity. In this post, you’ll learn how to create a One-to-One relationship between two entities using JPA in a Spring […]Continue reading
In Relational Database Management Systems (RDBMS), a stored procedure is a batch of prepared SQL code grouped as a logical unit that you store in the database. Stored procedures allow reusability of SQL code. In this post, I will explain how to call MySQL stored procedures from a Spring Boot application. Dependency For the application […]Continue reading
Consider a scenario where a database query matches over 1000 records. You need to display the query results to users. In this scenario, you probably won’t want to display all records on a single page. Instead, you would want to display chunks of data of suitable sizes with high readability. To achieve this, you use […]Continue reading
If you need to quickly create a JPA-based repository layer, Spring Data JPA is the right choice. You define your repository interface by extending one of the Spring Data JPA Repository interfaces. At runtime, Spring Data JPA will create your repository implementations with the common CRUD methods. You can then perform CRUD operations without writing […]Continue reading
When you are developing Spring Boot applications with database interactions, you typically use Hibernate as the Object Relationship Mapping (ORM) tool. Instead of directly coupling your code with Hibernate, often you’d rather use Spring Data JPA, a Spring Framework project. Spring Data JPA makes implementation of the data access layer incredibly easy by abstracting most […]Continue reading
Embedded JPA Entities are nothing new to the JPA standard. By defining Embedded JPA Entities, you can define a common data type for your application. Unlike regular JPA Entities which generally follow a table per entity mapping strategy. Embedded JPA Entities are stored as additional columns in the underlying relational database table. If you’re using […]Continue reading
This is the 4th part of my tutorial series on building a web application using Spring Boot. In the last part of the series, we looked at setting up Spring Data JPA for database persistence. In the second part of the series, we looked at using Thymeleaf for building the web pages. And we started […]Continue reading
In the first part of this tutorial series on creating a web application using Spring Boot, I showed how to use Spring Initializr to create the Maven project we’re using in this example. In the second part of the tutorial series, I showed you how to configure Spring MVC and ThymeLeaf templates to display a basic […]Continue reading
