Hibernate Dbcp Connection Pooling Configuration

This tutorial shows you how to configure Hibernate dbcp Connection Pooling. By default hibernate comes with a built-in connection pool. But this connection pool is by no means production ready. They even advice not to use it in production, as you can see in the logging.

Hibernate Date, Time and DateTime Mapping

In this tutorial we show how to work with java.lang.Date to store Date, Time and DateTime using Hibernate Annotations or XML Mappings. Hibernate allows various Java Date/Time classes to be mapped. Like the java.sql.Date, java.sql.Time or java.sql.Timestamp. But to avoid dependencies on the java.sql package, it’s common to use java.util or java.time Date/Time classes instead.

Hibernate @Embeddable and @Embedded Annotation Example

In this tutorial we show how to embed one entity inside another entity, so they are mapped to a single table. With Hibernate we can use the @Embeddable annotation to mark a class to be eligible as an embeddable class. We can use the @Embedded annotation to embed an embeddable class. The attributes of embedded class can be overridden using the @AttributeOverrides and the @AttributeOverride annotations. Let’s see how this works, by following this example.

JPA EntityManager Example

This tutorial shows how to work with the Java Persistence API. The purpose of JPA is to create an abstraction layer between the database layer and an ORM framework. This enables us to loosely couple our code with any ORM framework and easily change from vendor.
