Introduction to the Maven Build Lifecycle.The configuration of the Maven Processor Plugin looks as follows: This annotation processor scans our entities and embeddable classes, and creates the static metamodel classes.
Ensure that the plugin runs only the. 
Create an execution that invokes the plugin’s process goal in the generate-sources phase of the Maven default lifecycle. Configure the dependencies of this plugin and add the JPA static metamodel generator dependency (version 4.3.8) to the plugin's dependencies section. Add the Maven Processor Plugin (version 2.2.4) declaration to the plugins section of the pom.xml file. We can configure these tools by following these steps: Luckily, we can create these classes automatically by using the Maven Processor Plugin and the JPA Static Metamodel Generator. 
We want to use these classes because they give us the possibility to create type-safe criteria queries, but we don’t want to create them manually. These metamodel classes provide static access to the metadata that describes the attributes of our domain model classes.
Spring Data JPA Tutorial: Configuration describes how you can configure the persistence layer of a Spring application that uses Spring Data JPA.Ĭreating the JPA Static Metamodel ClassesĪ static metamodel consists of classes that describe the entity and embeddable classes found from our domain model. Spring Data JPA Tutorial: Getting the Required Dependencies describes how you can get the required dependencies. Spring Data JPA Tutorial: Introduction provides a quick introduction to Spring Data JPA and gives an overview of the Spring Data repository interfaces.
