如何向psql表添加维度约束？

Question

我正在动态创建地理服务器层，我想为它添加一些约束。我想要的约束CONSTRAINT enforce_dims_geom3 CHECK (st_ndims(geom) = 3) 我试着用

添加它

GSFeatureDimensionInfoEncoder dim3 = new GSFeatureDimensionInfoEncoder("ELE");
featureTypeEncoder.setMetadataDimension("elevation",dim3);

这根本不会影响结果。我该如何添加它？

修改

我正在使用GSAttributeEndcoder

创建图层

GSAttributeEncoder attribute = new GSAttributeEncoder();
        attribute.setAttribute(FeatureTypeAttribute.name, "geom");
        attribute.setAttribute(FeatureTypeAttribute.minOccurs, String.valueOf(0));
        attribute.setAttribute(FeatureTypeAttribute.maxOccurs, String.valueOf(1));
        attribute.setAttribute(FeatureTypeAttribute.nillable, String.valueOf(true));
        attribute.setAttribute(FeatureTypeAttribute.binding, "com.vividsolutions.jts.geom.Geometry");
        featureTypeEncoder.setAttribute(attribute);

GeoserverRestPublisher p = new GeoserverRestPublisher(stuff);
p.publishDBLayer(username, username, featureTypeEncoder, layerEncoder);
