Custom queries with CrudRepository

Question

I would like to custom my queries with CrudRepository :

This is my code:

@Repository
public interface CustomerRepository extends CrudRepository<Customer, Long> {

@Query("UPDATE customer c SET c.firstName = :firstName WHERE c.id = :id")
Integer setNewFirstNameForId(@Param("firstName") String firstName, @Param("id") long id);   
}



@Entity
public class Customer {

    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    private long id;
    private String firstName;
    private String lastName;

    protected Customer() {}

    public Customer(String firstName, String lastName) {
        this.firstName = firstName;
        this.lastName = lastName;
    }

    public long getId() {
        return id;
    }

    public void setId(long id) {
        this.id = id;
    }

    public String getFirstName() {
        return firstName;
    }

    public void setFirstName(String firstName) {
        this.firstName = firstName;
    }

    public String getLastName() {
        return lastName;
    }

    public void setLastName(String lastName) {
        this.lastName = lastName;
    }

    @Override
    public String toString() {
        return String.format(
                "Customer[id=%d, firstName='%s', lastName='%s']",
                id, firstName, lastName);
    }

But, when I compilate all of this, I have this an extract of the error : "Error creating bean with name 'customerRepository': Invocation of init method failed;..."

Thank advance,

edit :

This is my error :

Can you please accept an answer if someone solved your problem. – Prisca

Answer 1

Your first problem is in your JPQL:

@Query("UPDATE customer c SET c.firstName = :firstName WHERE c.id = :id")

type to

@Query("UPDATE Customer c SET c.firstName = :firstName WHERE c.id = :id")

That is because JPQL wants the query's table name to match your Entity Class name.

Another problem could be that you are missing the @Modifying annotation:

@Modifying
@Query("UPDATE customer c SET c.firstName = :firstName WHERE c.id = :id")
  Integer setNewFirstNameForId(@Param("firstName") String firstName, @Param("id") long id);   
}

Every time you want modify by query, you should add the @Modifying anotation because Spring needs to know about it.

Sorry for that, next time my question will be in comment. I also edited my message – Arcade

Thank !!, for update and delete I add "@Transactional" if not I am execution error. – Jeu

I think JPQL is only for suicidal people. Go figure out this subtle difference of Customer against customer .... – Melantha

Answer 2

Also take in account that when you're creating custom queries you must use the Entity structure and not the final database structure. For example you can have a composed private key. Then you Entity would have an attribute which would be the entity with the attributes that conform the private key. Example:

@Entity(name = "itemPrice")
public class ItemPriceEntity {

    @EmbeddedId
    private ItemPriceComposedPK composedPK;

    // Rest of the fields
    ...

    // Getters and setters
    ...
}

@Embeddable
public class ItemPriceComposedPK implements Serializable {

   @Column
   private String id;

   @Column
   private int iteration;

   // Getters and setters
   ...
}

If you want to use the field iteration, then you must code something like: i.composedPK.iteration. Example:

@Modifying
@Query("select i from itemPrice i where i.composedPK.iteration = :it")
public List<ItemPriceEntity> searchByIteration(@Param("it") String it);

Of course CrudRepository offers a better way to make this query without using custom queries but, as an example, is ok.

Answer 3

In query use model/entity name it should work.
