spring-boot - Neo4j 无法将 java.lang.Long 字段 model.Authority.id 设置为 model.Authority

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

我试图让 Neo4j 工作，但在尝试获取实体或持久化实体时我最终遇到了这个错误，但无法弄清楚。

我要做的就是保存一个权限

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

最佳答案

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 使其正常工作。

请注意 M4 有一个不同的问题，但 M3 也有效(尽管我认为没有理由比 M5 更进一步)

关于spring-boot - Neo4j 无法将 java.lang.Long 字段 model.Authority.id 设置为 model.Authority，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/46646798/
