Hibernate @ManyToMany mapping Generates different Join Table Name and trying to fetch Data from that, which doesn't exist.

The join table defined as "productcolumn_customfields" in @JoinTable mapping at entity, but it's expecting a different table and throwing the below

error:

Table 'product_columns_details_customviews' doesn't exist

Technologies used are: Spring-boot, Spring-data-Jpa, Hibernate, MySql

Complete Error is:
