First, I set mapping use kibana like this:  
`PUT location { "mappings": { "city": { "properties": { "city":{ "type": "text" }, "polygon":{ "type":"geo_shape" }, "time": { "type": "date" } } } } }`

[git@github.com](mailto:git@github.com):SenalChen/esDemo.git  
Then I got some exception.I don't know how to put a Object into elasticsearch.I must save some "polygon" to do some intersect.  
Is this means type is changed when some Object to Json, and how can I do it with an Java POJO?
