我試圖讓Neo4j工作，但最終得到這個錯誤時，要麼嘗試獲得一個實體，要麼堅持一個，並無法弄清楚。Neo4j無法設置java.lang.Long字段model.Authority.id到model.Authority
產生的原因：java.lang.IllegalArgumentException異常：不能sun.reflect java.lang.Long中的字段com.mycompany.mbi.dom.Authority.id設置爲com.mycompany.mbi.dom.Authority

和所有我想要做的是保存管理局
Authority authAdmin = new Authority();
authAdmin.setName(AuthoritiesConstants.ADMIN);
authAdmin = authorityRepository.save(authAdmin);
我無法重現錯誤（不得不增加一些科特林的DEP，使其工作） 。你可以嘗試更新到Spring引導2.0.0 M5？如果錯誤仍然存在，您可以嘗試使用其中一個模板進行重現：https：//github.com/neo4j-examples/neo4j-sdn-ogm-issue-report-template？ – nmervaillie
您是否找到解決方案？我遇到了與Spring Boot 2.0.0 M6相同的問題。 – Geir
我也想知道是否找到了解決方案。我在Spring Boot 2.0.0 M7上也遇到同樣的問題。不知道這是否是一個錯誤，我們是否必須等待這一個。 –
