There can be scenarios where you might need hbm files even if you are using annotations.Īnnotations are JPA2 specification compliant and will be available under javax.persistence.* package. One of the biggest advantages of using annotations over hbm files is that we can get rid of hbm files. Import .We can configure the metadata in entity class itself using annotation instead of configuring in hbm files.

Here is code of the PersonManager.java class: package Note that all the addresses have been persisted using Hibernate cascade functionality. This is the safest implementation of a singleton object.Now let’s create a PersonManager class which creates 2 person and 3 address objects and persists them to the database. Hence here we are creating just one static SessionFactory object when the class is first loaded and then we access the same via getSessionFactory() static method. Public Person(String firstName, String lastName) Ideally, it’s a good practice to create one SessionFactory object per data store at global application level scope. Create annotated model classesCreate model classes Person.java and map it to the database using annotations as follows: package This configuration will be used to create a Hibernate SessionFactory object. We also added couple of entities called Person and Address which we’ll configure later. Hibernate will optimize the generated SQL statements for MySQL. We also instructed Hibernate to use MySQLDialect i.e.

As you can see, we supplied database URL, username and password for the connection. Here we instructed Hibernate to connect to a MySQL database named hibernateTutorial. Setup Database ConfigurationCreate file as shown in above figure and configure the database connection and mapping classes.

You would need all the jar files under Hibernate\lib\required and Hibernate\lib\jpa directoriesĥ.

Let’s presume you’ve unzipped the Hibernate distribution zip to a directory called Hibernate.

    Identifies the owning side of columns which are necessary to identify a unique owning object This modifier holds the field which specifies the inverse side of the holding this many-to-many relationship, maps this field with an intermediary database join table specified by name modifier If name is not supplied it maps the class with a table having same name as the this class field as a primary key database to generate a value for this field this field with table column specified by name and uses the field name if name modifier is this field as the owning side of the many-to-many relationship and cascade modifier specifies which operations should cascade to the inverse side of relationship Quick reference on Hibernate annotations a class as a Hibernate Entity (Mapped this class with a database table specified by name modifier. class name defaults to table name and field names defaults to column names. Annotations are preconfigured with sensible default values, which reduce the amount of coding required, e.g. So use annotations only for table and column mappings, not for frequently changing stuff like database connection and other properties. XML also gives you the ability to change the configuration without building the project. Annotations are less powerful than XML configuration. When to use annotations?Use annotations to provide metadata configuration along with the Java code.

  • Obtain Session objects to perform a save operation using Hibernate APIsĢ.

  • Obtain connection using Configuration object and build a SessionFactory object.
  • Create model classes Person and Address and establish a many-to-many relationship between them and map them with database using annotations.
  • Create a database connection configuration using XML.
  • What’s in this tutorial?We’ll setup a sample Hibernate application here which demonstrates the usage of annotations.
