Neo4j无法设置java.lang.Long字段模型.Authority.id到model.Authority

时间：2017-10-09 12:44:10

标签： spring-boot neo4j maven-3 spring-data-neo4j-5

我试图让Neo4j工作，但是当我试图获得一个实体或者坚持一个实体时，我最终得到了这个错误，并且无法弄明白。

@Id

private Long id;

@NotNull

我所要做的就是拯救一个权威

Authority authAdmin = new Authority();
authAdmin.setName(AuthoritiesConstants.ADMIN);
authAdmin = authorityRepository.save(authAdmin);

1 个答案:

答案 0 :(得分：1)

我在Spring Boot 2.0.0 M6上遇到了同样的问题。通过恢复到2.0.0 M5来实现它。

请注意M4有不同的问题，但M3也有效（虽然我认为没有理由再回头比M5更多）
