Как внедрить Spring Data JPA с конфигурациями Hibernate .xml, но без использования Spring Boot?

0 голосов
/ 07 июня 2019

Я пытаюсь узнать, как интегрировать Spring Data JPA в проект Spring без использования Spring Boot.Все мои настройки Spring выполняются с помощью XML-файла.

Я застрял с этой проблемой, и поиск в Интернете не дает много полезных результатов, так как большинство людей используют Spring Data JPA с Spring Boot.

Я пытаюсь внедрить репозиторий Spring Data JPA в свой проект.В настоящее время для взаимодействия с базой данных используются Hibernate SessionFactory и Hibernate Query Language.

Я выполнил все необходимые реализации и конфигурации, но просто не могу понять, что является причиной ошибки.Я уменьшил и упростил мою программу (убрал фабрику сессий гибернации и заменил ее на entitymanager) для удобства чтения.Что я сделал не так?

Похоже, вы не включили создание репозиториев.

Добавьте следующие две части в конфигурацию контекста Spring: 

<beans ... other namespaces ...
  xmlns:jpa="http://www.springframework.org/schema/data/jpa"
  xsi:schemaLocation=" ... other schema locations
    http://www.springframework.org/schema/data/jpa 
    http://www.springframework.org/schema/data/jpa/spring-jpa-1.0.xsd">

<!-- 
Configure Spring Data JPA and set the base package of the 
repository interfaces 
-->
<jpa:repositories base-package="foo.bar.repository"/>

Полный пример приведен здесь: https://stackoverflow.com/a/25066939/66686
