Spring Boot ORM Maven EclipseLink

Spring Boot 默认使用 Hibernate 作为 ORM 实现。 为了使用 EclipseLink，我们首先需要从 pom.xml 中的 spring-data-jpa 依赖中排除 hibernate 依赖

<dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-data-jpa</artifactId>
   <exclusions>
      <exclusion>
         <groupId>org.hibernate</groupId>
         <artifactId>hibernate-entitymanager</artifactId>
      </exclusion>
      <exclusion>
         <groupId>org.hibernate</groupId>
         <artifactId>hibernate-core</artifactId>
      </exclusion>
   </exclusions>
</dependency>

现在在 pom.xml 中包含 eclipse-link 依赖项。

<dependency>
   <groupId>org.eclipse.persistence</groupId>
   <artifactId>org.eclipse.persistence.jpa</artifactId>
   <version>2.7.8</version>
</dependency>

以下是完整的 pom.xml
