Я проверил имена столбцов в БД, и все кажется правильным.Я не знаю причину неизвестного столбца 'travelplan0_.user_id' в 'списке полей, который я получаю.Я полагаю, что я также дважды проверил аннотации.

Трассировка стека: 

ERROR: Unknown column 'travelplan0_.user_id' in 'field list'

используйте referencedColumnName и укажите поле объекта, например id в UserDetails таблице, и используйте name="user_id", чтобы назвать его в таблице. 

    @JsonBackReference
    @ManyToOne(cascade= {CascadeType.DETACH, CascadeType.MERGE, CascadeType.PERSIST, CascadeType.REFRESH})
    @JoinColumn(name="user_id", referencedColumnName="id")
    private UserDetails userDetails;
...
