如何将neo4j ogm与非托管扩展集成？
我试图找到一些示例或演示“如何将OGM与非托管扩展集成”，但找不到任何好的示例 我尝试将restapi用作非托管扩展，并单独使用它，但OGM具有智能对象映射功能，可以通过如何将neo4j ogm与非托管扩展集成？,neo4j,spring-data-neo4j,neo4j-ogm,Neo4j,Spring Data Neo4j,Neo4j Ogm,我试图找到一些示例或演示“如何将OGM与非托管扩展集成”，但找不到任何好的示例 我尝试将restapi用作非托管扩展，并单独使用它，但OGM具有智能对象映射功能，可以通过会话实现，并且会话是从 会话工厂 private final static SessionFactory sessionFactory = new SessionFactory("some.domain"); sessionFactory .openSession(); 现在，OGM如何与非托管扩展集成使用
会话会话会话工厂 private final static SessionFactory sessionFactory = new SessionFactory("some.domain");
sessionFactory .openSession();
