![]() ![]() }In this case, Hibernate will look for the sequence named HIBERNATE_SEQUENCE, so you need to create such a sequence in the database, using the following statement: CREATE SEQUENCE "HIBERNATE_SEQUENCE" MINVALUE 1 MAXVALUE 100000 INCREMENT BY 1 START WITH 1 If you want to use another sequence name, use the as follows: = GenerationType.SEQUENCE, generator = "c_generator", sequenceName = "CUSTOMER_SEQUENCE") constructors, getters and setters go here. Private String = GenerationType.SEQUENCE) Use the following annotation for mapping the primary key field in a model class: = GenerationType.SEQUENCE)For example, the Customer class that maps to the Customers table in the database: = "CUSTOMERS") Create Sequence in Oracle databaseSince Oracle doesn’t have auto-increment feature for primary key, you must use sequence instead. Note that the persistence.xml file must be in the src/main/resources/META-INF folder. In case you use JPA/Hibernate, specify database connection properties in the persistence.xml file like this: Specify database connection propertiesIf you use file, specify connection properties for Oracle database as follows: that the file must be put in the src/main/resources folder of your project. in Eclipse IDE: In case you use Maven, add the following dependency into the pom.xml file: ĭue to Oracle’s license restriction, you can’t download the driver directly from Maven’s repository, so you have to use dependency like that.Ģ. Sign up is free).Extract the downloaded archive file and add the ojdbc8.jar to the project’s classpath, e.g. Choose the version according to your Oracle database installation (you must have an account in Oracle website to download. Click here to download Oracle Database JDBC driver. Use JDBC driver for Oracle databaseA JDBC driver for Oracle must be present in your project’s classpath. ![]() The code examples below are tested with Hibernate 5 and Oracle Express database 18c. The ZonedDateTime class is one of them.In this Hibernate tutorial, I will guide you how to configure Hibernate framework to work with Oracle database. Since version 5, Hibernate supports some classes of the Date and Time API as basic types. To sum them up, all attendees wanted to know what’s the best way to persist an attribute of type ZonedDateTime with Hibernate. During last week’s Hibernate workshop, I got a few questions about Hibernate’s handling of ZonedDateTime objects. ![]()
