私は、PostgreSQL DB + PostGIS で Spring + Hibernate をGeometry使用しています。これは、DB で CRUD 操作を実行し、Jackson JSON ビューを使用して JSON 出力を返します。を追加するまでは正常に機能していましたGeometry。オブジェクトを検査すると、検索は正しい出力を返しますが、Geometry. 私はこのようなものを得る：
org.springframework.http.converter.HttpMessageNotWritableException: Could not write JSON: This method does not support GeometryCollection arguments (through reference chain: java.util.ArrayList[0]->com.tutorial.jquery.model.State["geom"]->com.vividsolutions.jts.geom.MultiPolygon["boundary"]->com.vividsolutions.jts.geom.MultiLineString["boundary"]->com.vividsolutions.jts.geom.MultiPoint["boundary"]->com.vividsolutions.jts.geom.GeometryCollection["boundary"]); nested exception is org.codehaus.jackson.map.JsonMappingException: This method does not support GeometryCollection arguments (through reference chain: java.util.ArrayList[0]->com.tutorial.jquery.model.State["geom"]->com.vividsolutions.jts.geom.MultiPolygon["boundary"]->com.vividsolutions.jts.geom.MultiLineString["boundary"]->com.vividsolutions.jts.geom.MultiPoint["boundary"]->com.vividsolutions.jts.geom.GeometryCollection["boundary"])
