How to search through array in Spring Boot CrudRepository

Question

Say, I have the following entity class:

Person.java

@Entity
public class Person {
  @Id
  private String name;

  private String[] c         


        

Answer 1

Ideally, You should declare cars as a separate Entity like this

@Entity
public class Person {
  @Id
  private String name;

  private List cars;

  // Constructor, getters and setters
}

If not you should change Array to List at the least. change

private String[] cars;

to

@ElementCollection
private List cars;

Then You have to write a Query like this

@Query("select p from Person p WHERE :car in elements(p.cars)")
List getAllByCars...(@Param("car") String car)
