GraphDB 8.6.1 Free-地理空间谓词不适用于运行时，但适用于Workbench

时间：2018-12-06 12:54:29

标签： geospatial graphdb geosparql

我正在使用未启用规则集的回购。 Query_1 使用 geof：sfIntersects（），而 Query_2 使用 geo：sfIntersects 谓词。 使用Workbench v8.6.1，Query_1可以正确执行，而Query_2不能正确执行，不返回任何行，如文档中所述。 启用GeoSPARQL插件后，使用工作台可以正确执行两个查询，但是Query_2更快。 使用Java POM中的Runtime v8.6.1，我尝试针对启用了GeoSPARQL插件的仓库执行Query_1和Query_2。 Query_1可以正确执行（与Workbench一样），但是Query_2不能正确执行而不返回任何行（就像禁用了GeoSPARQL插件一样！）。 我有证据表明已启用GeoSPARQL插件，因为如果我在工作台上重复执行相同的任务，则两个查询都会成功，同时 /storage/GeoSPARQL/v2/config.properties 具有以下内容：

#GeoSPARQL configuration
#Thu Dec 06 09:30:54 EET 2018
precision=11
prefixtree=QUAD
prefixtree.current=QUAD
precision.current=11
enabled=true

java选项正确指向 -Dregister-external-plugins = / home / tioannid / graphdb-free-8.6.1 / lib / plugins

如果此功能仅在Workbench上正常工作，那就太浪费了。

使用选项 -Dgraphdb.extra.plugins = 插件路径 运行该应用程序。
在 pom.xml 中，我包括了 graphdb-runtime ，但排除了一些包含 lucene 的依赖项（因为在类路径上可能有多个lucene是危险）：
