使用密码查询导入neo4j形状文件中的错误
使用密码查询导入neo4j形状文件中的错误
提问于 2020-11-12 11:34:31
我已经安装在下面，
带有0.26.2-neo4j-3.5.2版本的
- Neo4j桌面IDE - 3.5.17
- Java版本8
试图通过密码查询将形状文件导入neo4j
spatial.importShapefile("file:///home/.local/share/neo4j-relate/dbmss/dbms-3ad2b2c1-94c6-4482-8b1f-bcfe3f413670/import/cb_2019_us_state_500k.shp") 调用
但是它会产生错误:未能调用过程spatial.importShapefile：引起的: java.lang.NoClassDefFoundError:未能初始化类org.geotools.data.DataUtilities
怎么解决这个问题？有人能告诉我们如何解决这个问题吗？

看来您也在Neo4j社区中发布了这个问题。我已经在那里回答过了，但在这里也要回答。
不确定是否解决了这个问题，但是我能够将shapefile导入到数据库中。我的配置-> Neo4j 3.5.20 Java 9 ne4j- same 0.26.2 shapefile -> https://www2.census.gov/geo/tiger/GENZ2019/shp/的源代码(我猜您也在使用相同的文件)。确保像prj、dbf这样的所有文件都位于同一个目录中。(neo4j的垃圾箱)
您能否检查配置中是否有白色和无限制的空间。*插件。
