Hibernate simplifies data handling between SQL and JDBC by mapping the Object-Oriented model in Java with the Relational model in Databases. Althoughmapping of basic Java classes is in-built in Hibernate, mapping of custom types is often complex. In this tutorial, we’ll see how Hibernate allows...
Here is the implementation of NHibernate mapping file.<?xml version = "1.0" encoding = "utf-8" ?> <hibernate-mapping xmlns = "urn:nhibernate-mapping-2.2" assembly = "NHibernateDemoApp" namespace = "NHibernateDemoApp"> <class name = "Student"> <id name = "ID"> <generator class =...

For Hibernate 6, you can use the @Type annotation when mapping an entity attribute on a JSON column:@Type(JsonType.class) private Map<String, String> properties = new HashMap<>();For Hibernate 5, you can use the @TypeDef annotation to make use of the JSON Hibernate Types:...
We learned aboutmapping associated entitiesin hibernate already in previous tutorials such asone-to-one mappingandone-to-many mappings. There we wanted to save the mapped entities whenever the relationship owner entity gets saved. To enable this behavior, we had used “CascadeType” attribute. ...

Since its introduction in Java 8, the Stream API has become a staple of Java development. The basic operations like iterating, filtering, mapping sequences of elements are deceptively simple to use. But these can also be overused and fall into some common pitfalls. To get a better understandi...
Think of a Hibernate type as a bridge between a Java type (object or primitive) and an SQL type. Hibernate ORM comes with a built-in set of supported types, but there are also other Java types that Hibernate doesn't support (e.g., java.time.YearMonth int
If you're using Hibernate 5, you can either provide the fully-qualified name of the Hibernate Type: @Type(type = "io.hypersistence.utils.hibernate.type.json.JsonType") Or, you can add the following mapping to yourpackage-info.javaclass in the same package where your JPA entities are locat...
