将ShapefileDataStore转换为JDBCDataStore失败，名称更改

Question

// Given
println(shpDataStore)
//ShapefileDataStore [file=file:/opt/c_1970-01-01T00-00-00.shp, charset=ISO-8859-1, timeZone=sun.util.calendar.ZoneInf [id="UTC",offset=0,dstSavings=0,useDaylight=false,transitions=0,lastRule=null], memoryMapped=false, bufferCachingEnabled=true, indexed=true, fidIndexed=true]

println(jdbcDataStore)
// org.geotools.jdbc.JDBCDataStore@4371a490

// Works
val features = shpDataStore.getFeatureSource(sourceTypeName).getFeatures
val featureType = features.getSchema
val featureTypeName = featureType.getName.getLocalPart

jdbcDataStore.createSchema(featureType)

val newType = jdbcDataStore.getSchema(featureTypeName)

val reTypedSFC = new TypeUpdatingFeatureCollection(features, newType)

val fs: FeatureStore[SimpleFeatureType, SimpleFeature] = jdbcDataStore.getFeatureSource(featureTypeName).asInstanceOf[FeatureStore[SimpleFeatureType, SimpleFeature]]

fs.addFeatures(reTypedSFC)


// Doesn't work
val features = shpDataStore.getFeatureSource(sourceTypeName).getFeatures
val featureName = "newName"
val originalFeatureType = features.getSchema
val sftBuilder = new SimpleFeatureTypeBuilder()
sftBuilder.init(originalFeatureType)
sftBuilder.setName(featureName)
val featureType = sftBuilder.buildFeatureType()

val featureTypeName = featureType.getName.getLocalPart

jdbcDataStore.createSchema(featureType)

val newType = jdbcDataStore.getSchema(featureTypeName)

val reTypedSFC = new TypeUpdatingFeatureCollection(features, newType)

val fs: FeatureStore[SimpleFeatureType, SimpleFeature] =
      jdbcDataStore.getFeatureSource(featureTypeName).asInstanceOf[FeatureStore[SimpleFeatureType, SimpleFeature]]

fs.addFeatures(reTypedSFC)

// Output is
//java.lang.IllegalArgumentException: Value c_1970-01-01T00-00-00.1 illegal for type java.lang.Integer
//        at org.geotools.jdbc.JDBCDataStore.decodeFID(JDBCDataStore.java:1890)
//        at org.geotools.jdbc.JDBCDataStore.insert(JDBCDataStore.java:1523)

更新：

我尝试过

val f = shpDataStore.getFeatureSource(sourceTypeName).getFeatures
val ty = f.getSchema
val builder = new SimpleFeatureBuilder(ty)
val features = new DefaultFeatureCollection()
f.features().foreach { j =>
  builder.init(j)
  features.add(builder.buildFeature(null))
  builder.reset()
}

但是我仍然得到

fs.addFeatures（reTypedSFC）java.lang.IllegalArgumentException：值fid--31eafd14_14a112b8f13_-6cbb对于类型java.lang.Integer是非法的在org.geotools.jdbc.JDBCDataStore.decodeFID（JDBCDataStore.java:1890）

Answer 1

问题是，对于shapefile，特征标识符（FID）是一个包含一些随机内容（文件名，日期，特征的哈希码等）的字符串。在数据库中时，如果已定义，则通常基于主键。

因此，您需要将功能的字段替换为NULL，以便JDBCStore在将其添加到表时可以创建一个新的字段。或更改表以接受ID列中的字符串。

Answer 2

这受伊恩（Ian）的回答和我自己的一点研究启发，似乎解决了这个问题。

val builder = new SimpleFeatureBuilder(simpleFeature.getFeatureType)
builder.init(simpleFeature)
builder.featureUserData(Hints.USE_PROVIDED_FID, false)
val featureNoId: SimpleFeature = builder.buildFeature(null)

尽管将id=null传递给buildFeature，您仍然必须将USE_PROVIDED_FID提示设置为false。
