Tip: Creating a Spring Read Only and Native Query
For reading operations, the transaction configuration readOnly flag should be set to true and in order to execute native queries, the @Query annotation parameter, nativeQuery flag, should be set to true.

To allow your query methods to be transactional, you should use @Transactional at the repository interface that you define. For reading operations, the transaction configuration readOnly flag should be set to true and in order to execute native queries, the @Query annotation parameter, nativeQuery flag, should be set to true, as you will see in the snippet of code below:
//before using the readOnly and nativeQuery flags
@Transactional()
@Query(value="...")
//after setting the readOnly and native query flags to true
@Transactional(readOnly=true)
@Query(value="...", nativeQuery=true)
