Question

我刚尝试在gremlin控制台上运行Frames上的简单演示：

TinkerGraph graph = TinkerGraphFactory.createTinkerGraph();

FramedGraphFactory factory = new FramedGraphFactory(new GremlinGroovyModule());

添加import com.tinkerpop.frames.*;后（是的，tinkerpop框架在我的类路径中）但控制台无法识别FramedGraphFactory类。

事实上，如果我运行

gremlin> show classes

命令，它回复说没有加载任何内容。任何线索？

由于

PS详情：我在Ubuntu上，下载了gremlin-groovy-2.4.0。

我还下载了jar jar，并设置了classpath：

echo $CLASSPATH

/home/dev/frames-2.5.0.jar

然后启动gremlin并导入框架：

import com.tinkerpop.frames.*

终于

TinkerGraph graph = TinkerGraphFactory.createTinkerGraph();

FramedGraphFactory factory = new FramedGraphFactory(new GremlinGroovyModule());

产生

groovysh_evaluate: 50: unable to resolve class FramedGraphFactory 
 @ line 50, column 30.
   FramedGraphFactory factory = new FramedGraphFactory(new GremlinGroovyModule()); //(1) Factories should be reused for performance and memory conservation.
                                ^
groovysh_evaluate: 50: unable to resolve class GremlinGroovyModule 
 @ line 50, column 53

Answer 1

试试这个：

gremlin> Grape.grab([group:"com.tinkerpop",module:"frames",version:"2.4.0"])
==>null
gremlin> graph = TinkerGraphFactory.createTinkerGraph()                     
==>tinkergraph[vertices:6 edges:6]
gremlin> import com.tinkerpop.frames.*                                      
==>import com.tinkerpop.gremlin.*
==>import com.tinkerpop.gremlin.java.*
==>import com.tinkerpop.gremlin.pipes.filter.*
...
==>import groovy.grape.Grape
==>import com.tinkerpop.frames.*
gremlin> import com.tinkerpop.frames.modules.gremlingroovy.*                
==>import com.tinkerpop.gremlin.*
==>import com.tinkerpop.gremlin.java.*
==>import com.tinkerpop.gremlin.pipes.filter.*
==>import com.tinkerpop.gremlin.pipes.sideeffect.*
...
gremlin> factory = new FramedGraphFactory(new GremlinGroovyModule());       
==>com.tinkerpop.frames.FramedGraphFactory@645c1312

如果您已经复制了jar，则在开始时省略Grape的使用，但如果您复制，请确保您拥有所有Frames依赖项而不仅仅是Frames jar本身（Grape隐藏了这些东西）

Gremlin和框架
