I have an issue which is driven me crazy. I have two apps (Taco Cloud example apps from Spring in Action 5, book) The jpa is working OK. It contain some scripts to generate database schema. One of the generated tables is named taco_order_tacos, it is all-key entity and the generated ids are : order_id and taco_id. Exactly same script and same Entity objects fail in another project, because CrudRepository looks for a tacos_id (with s at the end of taco word, plural) when try to save an object (Order). By the way, both projects are using same spring-boot-starters dependencies. Of course adding "s" to taco_id (tacos_id) on failing project's taco_order_tacos table, it is working fine, but I need to understand what is going on. Thanks in advance for any help.
Here is error stack:
There was an unexpected error (type=Internal Server Error, status=500).
could not prepare statement; SQL [insert into taco_order_tacos (order_id, tacos_id) values (?, ?)]; nested exception is org.hibernate.exception.SQLGrammarException: could not prepare statement

EDITION TO ADD SOME CODE:
Here is the class which is creating the conflict, but is exactly same class on OK project. As you can see, there are no columns/table renaming, so IMO, there is no point to try to make an insert on Tacos_ID, when table name is Taco:
@Data
@Entity
public class Taco {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
@NotNull
@Size(min=5, message="Name must be at least 5 characters long")
private String name;
private Date createdAt;
@ManyToMany(targetEntity=Ingredient.class)
@Size(min=1, message="You must choose at least 1 ingredient")
private List<Ingredient> ingredients;
@PrePersist
void createdAt() {
this.createdAt = new Date();
}
}
