Getting started¶

Adding the dependency¶

To use this library in a Maven project, add the following to your pom.xml:

<dependency>
    <groupId>nl.datastations</groupId>
    <artifactId>dans-jpa-converter-lib</artifactId>
    <version>1.0.1-SNAPSHOT</version>
</dependency>

Using a converter¶

The converters in this library are used on entity fields annotated with JPA's @Convert. For example, UriConverter allows you to store a URI in a database as a string instead of as a serialized object.

import java.net.URI;
import javax.persistence.Convert;
import javax.persistence.Entity;
import javax.persistence.Table;

import nl.knaw.dans.convert.jpa.UriConverter;

@Entity(name = "MyEntity")
@Table(name = "my_entity")
public class MyEntity {

    @Convert(converter = UriConverter.class)
    private URI uri;
}
