JPA @Jointable

When you test the jointable annotation feature, you specify the table name, for example:

@ManyToManyprivate set<roleentity> roles, @JoinTable (name= "User_role", [email protected] (name = "user_id"), [ Email protected] (name = "role_id")) @ManyToManypublic set<roleentity> GetRoles () {return roles;}

i.e. @jointalbe (name= "User_role")

But the JPA interface always looks for the default table Users_roles (because the names of the two tables you want to correlate are users,roles), it's strange.

After debugging, find the following changes

1 @JoinTable (name= "User_role", [email protected] (name = "user_id"), [email protected] (name = "role_id")) 
   2    @ManyToMany3     private set<roleentity> roles;

Note that loading is smooth
