我尝试使用此行

GeoPipeline pipeline = GeoPipeline.start( layer )
                .copyDatabaseRecordProperties( "name" )
                .propertyFilter( "name", "Storgatan" );

但是它在.propertyFilter()

的行中引发了这个异常
 Exception in thread "main" java.lang.NoClassDefFoundError: com/tinkerpop/pipes/filter/FilterPipe$Filter
    at org.neo4j.gis.spatial.pipes.filtering.FilterProperty.<init>(FilterProperty.java:39)

我正在使用neo4j-spatial 1.9.5和相同的neo4j

有谁知道这个问题是什么?

您的类路径似乎需要Tinkerpop堆栈。如果你正在使用maven,请使用:

<dependency>
  <groupId>com.tinkerpop</groupId>
  <artifactId>pipes</artifactId>
  <version>2.4.0</version>
</dependency>

如果您需要Neo4j的蓝图API,请使用以下命令:

<dependency>
   <groupId>com.tinkerpop.blueprints</groupId>
   <artifactId>blueprints-neo4j-graph</artifactId>
   <version>2.4.0</version>
</dependency>
