如何解决使用密码查询的neo4j导入Shape文件中的错误
我已经在下面安装了，
- 具有neo4j版本的Neo4j桌面IDE-3.5.17
- Java版本8
- 空间0.26.2-neo4j-3.5.2
尝试通过密码查询将形状文件导入neo4j，
调用space.importShapefile（“ file：///home/.local/share/neo4j-relate/dbmss/dbms-3ad2b2c1-94c6-4482-8b1f-bcfe3f413670/import/cb_2019_us_state_500k.shp”）
但是会产生错误：
无法调用过程spatial.importShapefile：原因：java.lang.NoClassDefFoundError：无法初始化类org.geotools.data.DataUtilities
该如何解决？谁能告诉解决这个问题？
解决方法
您似乎也在 Neo4j 社区中发布了该问题。我已经在那里回答了，但也要在这里回答。
不确定，这是否已解决，但我能够将 shapefile 导入数据库。 我的配置-> Neo4j 3.5.20 Java 版本 9 neo4j-spatial-0.26.2 shapefile 的来源 -> https://www2.census.gov/geo/tiger/GENZ2019/shp/ （我猜您也在使用相同的文件）。确保 prj、dbf 等所有文件都在同一目录中。 （neo4j 的 bin）
您能否检查配置中是否有白名单和不受限制的空间插件。
