【问题标题】:Error in Import Shape file of neo4j using cypher query使用密码查询导入 Neo4j 形状文件时出错
【发布时间】:2021-02-24 09:54:48
【问题描述】:

我已经在下面安装了,

  1. 带有 neo4j 版本的 Neo4j 桌面 IDE - 3.5.17
  2. Java 版本 8
  3. 空间 0.26.2-neo4j-3.5.2

尝试通过密码查询将shape文件导入neo4j,

调用 spatial.importShapefile("file:///home/.local/share/neo4j-relate/dbmss/dbms-3ad2b2c1-94c6-4482-8b1f-bcfe3f413670/import/cb_2019_us_state_500k.shp")

但它会产生错误: 无法调用过程spatial.importShapefile:原因:java.lang.NoClassDefFoundError:无法初始化类 org.geotools.data.DataUtilities

如何解决这个问题?谁能告诉我解决这个问题?

    【解决方案1】:

    看起来你也在 Neo4j 社区中发布了这个问题。我已经在那里回答了,但也将在这里回答。

    不确定是否已解决,但我能够将 shapefile 导入数据库。 我的配置-> Neo4j 3.5.20 Java 版本 9 neo4j-空间-0.26.2 shapefile 的来源 -> https://www2.census.gov/geo/tiger/GENZ2019/shp/(我猜你也在使用同一个文件)。确保所有文件(如 prj、dbf)都在同一目录中。 (neo4j的bin)

    您能否检查配置中是否包含白名单和不受限制的空间。* 插件。
