1.使用Neo4jRepository的时候报错：

Could not find mappable nodes or relationships inside Record<{m: node<1212>}> for 
org.springframework.data.neo4j.core.mapping.DefaultNeo4jPersistentEntity@6662974a

2.看一下dao层的代码
在这里插入图片描述
相信大家也看出来了，这里的实体类泛型写错了，它应该是Neo4j数据库中操作的对象类型，正确的是下面这样

public interface ColumnsMapper extends Neo4jRepository<GraphColumn, Long> {

    @Query("MATCH (n:Column) where id(n) = $id return n")
    GraphColumn getColumnInfo(@Param("id") Long id);
}
