Service Builder Persistence

Liferay’s Service Builder can generate your project’s persistence layer by automating the creation of interfaces and classes. Your application’s persistence layer persists data represented by your configured entities to a database. In fact, your local service implementation classes are responsible for calling the persistence layer to retrieve and store your application’s data. So instead of taking the time-consuming route of writing your own persistence layer, you can use Service Builder to quickly define your entities and generate the layer instantaneously.

Here’s what these tutorials cover:

• Defining an object-relational map and generating your persistence layer from that map
• Running Service Builder
• Understanding and using local and remote services Service Builder generates
• Using the ServiceContext class
• Customizing model entities with Model Hints
• SQL queries
• Using Hibernate’s criteria API
• Configuring service.properties
• Connecting Service Builder to external data sources
