In this tutorial, we’ll learn how to work with relationships between entities in Spring Data REST. We’ll focus on the association resources that Spring Data REST exposes for a repository, considering each type of relationship that we can define. To avoid any extra setup, we’ll use the H2 embedded database for the examples. We can find the list of r...
2.1. The Data Model
Let’s define two entity classes, Library and Address, having a one-to-one relationship by using the @OneToOne annotation. The association is owned by the Libraryend of the association: The @RestResourceannotation is optional, and we can use it to customize the endpoint. We must also be careful to have different names for each association resource. Otherwise, we’ll encounter a JsonMappingException with the message “Detected multiple association links with same relation type! Disambiguate assoc...
2.2. The Repositories
In order to expose these entities as resources, we’ll create two repository interfaces for each of them by extending the CrudRepositoryinterface:
2.3. Creating the Resources
First, we’ll add a Libraryinstance to work with: Then the API returns the JSON object: Note that if we’re using curl on Windows, we have to escape the double-quote character inside the String that represents the JSONbody: We can see in the response body that an association resource has been exposed at the libraries/{libraryId}/addressendpoint. Before we create an association, sending a GET request to this endpoint will return an empty object. However, if we want to add an association, we must...
We define a one-to-many relationship using the @OneToMany and @ManyToOne annotations. We can also add the optional @RestResourceannotation to customize the association resource.
We define a many-to-many relationship using the @ManyToMany annotation, to which we can also add @RestResource.
Let’s create a test class that injects a TestRestTemplateinstance, and defines the constants we’ll use:
In this article, we demonstrated the use of different types of relationships with Spring Data REST. The full source code of the examples can be found over on GitHub.
