QUESTION
I'm trying to set up a simple one to many relationship with two objects and attempting to follow some code I found here: https://github.com/hellokoding/jpa-onetomany-springboot-maven-mysql/blob/master/src/main/java/com/hellokoding/jpa/model/BookCategory.java#L29.
However, I'm getting issues when attempting to save an item to the specific database. I'm currently getting a 407 error based on my flt_id when attempting to save an object to my database.
Fleet object (I don't have any @OneToMany set just yet because I'm trying to simply save an object of this type to the database first before I attempt the @OneToMany stuff. Might this be the problem? Do I need to set up the entire thing, otherwise it breaks?)
...ANSWER
Answered 2020-Jul-02 at 00:06@Entity
public class Fleet{
...
@OneToMany(mappedBy = "fleet", cascade = CascadeType.ALL)
private List fleetSerialNo;
...
}
