Geoserver在创建时动态设置数据存储区/图层的边界框/ referencedEnvelope

Question

I am using geoserver . I extended ContentDataStore plugin to add csv data types as layers. I am using geoserver rest api , HTTPUtils.put method actually. When I do this the datastore gets created without boundingbox defined, unlike when it is created manually on geoserver web application . Therefore I get an exception when I try to use wms-getCapabilities method, because there is no boundingbox defined.

The getCapabilities query is below:
localhost:8090/geoserver/wms?Service=WMS&Version=1.1.1&Request=GetCapabilities

The inner exception is below:
Caused by: java.lang.NullPointerException
    at org.geoserver.wms.capabilities.GetCapabilitiesTransformer$CapabilitiesTranslator.handleLatLonBBox(GetCapabilitiesTransformer.java:1349)
    at org.geoserver.wms.capabilities.GetCapabilitiesTransformer$CapabilitiesTranslator.handleLayer(GetCapabilitiesTransformer.java:901)
    at org.geoserver.wms.capabilities.GetCapabilitiesTransformer$CapabilitiesTranslator.handleLayerTree(GetCapabilitiesTransformer.java:826)
    ... 90 more

Is there a way to define boundingbox for a datastore/layer in xxxDataStore or xxxDataStoreFactory classes. So far I couldn't find any way to define while creating the datastore.

Thanks in advance

Answer 1

I found the answer to it. I changed 2 classes. The first one is xxxFeatureSource which extends ContentFeatureSource (it's in ContentDataStore plugin) and the second one is DataStoreFileResource .

In xxxFeatureSource I overrided ReferencedEnvelope getBoundsInternal() method and implemented code which calculates my boundingBox.

In DataStoreFileResource I added this line;

ftInfo.setLatLonBoundingBox( bounds );

into the void handlePut() method, right after ftInfo.setNativeBoundingBox( bounds ) .

Now I can use getCapabilities method after adding my DataStore via GeoServer rest api.

Hope it helps others too.
