[FIXED] Spring Data JPA update query (Not supported for DML operations)

Issue

I'm having problems executing an update query in springdatajpa. here is the code in the repository layer:

@Transactional
@Modifying
@Query("update CustomerTransaction ct set ct.amountPayment =:trnAmount WHERE ct.loanAccount.id=:loanAccountId AND ct.paymentTerm=:paymentTerm")
List<CustomerTransaction> updateCurrentCustomerTransaction(@Param("loanAccountId") long loanAccountId, 
                                                            @Param("paymentTerm") int paymentTerm, 
                                                            @Param("trnAmount") BigDecimal trnAmount); 

As you can see, I've already added the @Modifying annotation but it still throws an error of "Not supported for DML operations" I am using Hibernate 5.4. Any help would be highly appreciated.

Solution

You need to set the return type of your method to void or int.
