Как получить тип PGInterval для правильной десериализации

0 голосов
/ 30 апреля 2019

Я пытаюсь написать Java-приложение для извлечения данных из базы данных postgreSQL с полями интервала и продолжаю получать ошибки, связанные с полем. Урезанная версия программы на https://github.com/sashle63/pg-interval-test

README.md имеет выходные и консольные журналы для варианта в каждой ветви.

Я пробовал два подхода к реализации этой модели

1. Используйте тип PGInterval в postgrsql-42.2.5 на моей модели (основная ветвь) При таком подходе я получаю ответ: 

{ "timestamp": "2019-04-30T15:47:24.565+0000", "message": "could not deserialize; nested exception is org.hibernate.type.SerializationException: could not deserialize", "details": "uri=/api/testrecords" }

С консольным журналом:

2. Я нашел несколько руководств по созданию расширений UserType для Hibernate (ветка usertype) При таком подходе я получаю эту ошибку вместо: 

{ "timestamp": "2019-04-30T19:46:17.474+0000", "message": "Could not set field value [PT1H] value by reflection : [class com.example.pgintervaltest.model.Tester.testInterval] setter of com.example.pgintervaltest.model.Tester.testInterval; nested exception is org.hibernate.PropertyAccessException: Could not set field value [PT1H] value by reflection : [class com.example.pgintervaltest.model.Tester.testInterval] setter of com.example.pgintervaltest.model.Tester.testInterval", "details": "uri=/api/testrecords" }

Моя модель: 

@Entity
@Table(name = "tb_testinterval")
public class Tester {

    @Id
    @Column(name = "test_id", nullable = false)
    private Integer testId;

    @Column(name = "test_interval", nullable = false)
    @Type(type = "com.example.pgintervaltest.types.PGIntervalType")
    private PGInterval testInterval;

Когда я выполняю код, я хотел бы видеть что-то вроде этого: 

[
{ "testId": 1, "testInterval" : "01:00:00" },
{ "testId": 2, "testInterval" : "02:00:00" },
{ "testId": 3, "testInterval" : "03:00:00" }
]
