将gremlin控制台输出转换为json [英] convert gremlin console output into json

问题描述

我正在尝试将gremlin控制台的输出转换为json格式，

I am trying to convert the output of gremlin console into json format,

对于Ex: gremlin> g.V(409608).valueMap()

样本输出:[eName:[FS-BR-GOJU-ENB-G001_MW]，lng:[000086.2119100]，调制:[2048]，城市:[Jamshedpur]，hopType:[1 + 0]，eType:[MICROWAVE]，cTime:[周六3月03日20:37:27 IST2018]，aendSapId:[FS-BR-JMDP-ENB-6005]，供应商:[CERAGON]，域名:[MW]，位置:[POINT(86.21191 22.79906)]，状态:[Jharkhand]，m时间:[Sat Mar 03 20:37:27 IST2018]，lat:[000022.7990600]，sapId:[FS-BR-GOJU-ENB-G001]]

sample OUTPUT : [eName:[FS-BR-GOJU-ENB-G001_MW],lng:[000086.2119100],modulation:[2048],city:[Jamshedpur],hopType:[1+0],eType:[MICROWAVE],cTime:[Sat Mar 03 20:37:27 IST 2018],aendSapId:[FS-BR-JMDP-ENB-6005],vendor:[CERAGON],domain:[MW],location:[POINT (86.21191 22.79906)],state:[Jharkhand],mTime:[Sat Mar 03 20:37:27 IST 2018],lat:[000022.7990600],sapId:[FS-BR-GOJU-ENB-G001]]

如何将其转换为json?

how can i convert it into json ??

这个"g.V(409608).valueMap()" 只是一个例子，我在寻找一种可以将任何类型的查询输出转换为json的函数/方式.

This "g.V(409608).valueMap()" is just an example, i was looking for a function/way that can convert any type of query output into json.

实际上，我正在尝试开发一种功能，其中我有一个gremlin查询作为字符串("gremlin查询")，并且我需要使用JSON (使用JAVA)的输出.

Actually i am trying to develop a feature in which i have a gremlin query as string ("gremlin query") and i need its output in JSON (USING JAVA).

推荐答案

如果创建Jackson ObjectMapper

You can serialize to GraphSON if you create a Jackson ObjectMapper:

gremlin> mapper = GraphSONMapper.build().version(GraphSONVersion.V3_0).create().createMapper()
==>org.apache.tinkerpop.shaded.jackson.databind.ObjectMapper@7e97551f
gremlin> v = g.V().has('name','marko').valueMap(true).next()
==>id=1
==>name=[marko]
==>age=[29]
==>label=person
gremlin> mapper.writeValueAsString(v)
==>{"@type":"g:Map","@value":[{"@type":"g:T","@value":"id"},{"@type":"g:Int32","@value":1},"name",{"@type":"g:List","@value":["marko"]},"age",{"@type":"g:List","@value":[{"@type":"g:Int32","@value":29}]},{"@type":"g:T","@value":"label"},"person"]}

如果要使用非嵌入式类型的JSON，可以使用GraphSON 1.0

If you want JSON with non-embedded types, you could use GraphSON 1.0

gremlin> mapper = GraphSONMapper.build().version(GraphSONVersion.V1_0).create().createMapper()
==>org.apache.tinkerpop.shaded.jackson.databind.ObjectMapper@4a3be6a5
gremlin> mapper.writeValueAsString(v)
==>{"id":1,"name":["marko"],"age":[29],"label":"person"}
