gis - how to save geojson(in javascript) to geometry(MultiPolygon,4326) in PostGIS with Hibernate -

I am working on JSF Project (version 2.2) I have a geographic object in javascript. On the other hand, I am using Hibernate 4.3.8 and PostGrussCl 9.3, a column of type of Grametry (multiplex, 4326) in postgis on the other side.

Geometric column definition in model class

  @ type ("type =" org.hibernate.spatial.GeometryType ") @column (name =" geome ") private polygon Land;  

I have also included Hibernate Spectile 4.x in my project and I can access the GeoZone string in Managed Bean. But I do not know how I can do this in my database. I might have to parse geogeogen and by geographical coordinates I will not have succeeded, but what is the way to do that?

Thank you in advance.
