使用GEOTools为shp文件写入数据
在上一篇我们已经建立了一个空的shp文件，接着我们为这个空文件装入数据，这个功能主要用到SimplefeatureStore.addFeatures()这个方法，传入的属性是Transaction
transaction = new
DefaultTransaction(null)，这里的null是可以设置string类型的值的，这个值有什么影响还不清楚，求助大神！
if (SHPfile ==
null)
{
return;
}
FileDataStore store =
FileDataStoreFinder.getDataStore(SHPfile);
String typeName =
store.getTypeNames()[0];
JOptionPane.showMessageDialog(null, “This is the
typeName=”+typeName);
SimpleFeatureSource featureSource =
store.getFeatureSource(typeName);
SimpleFeatureStore SimplefeatureStore = (SimpleFeatureStore)
featureSource;
SimpleFeatureCollection SimpleFeaturecollection = new
ListFeatureCollection(TYPE, features);
Transaction transaction = new DefaultTransaction(null);
SimplefeatureStore.setTransaction(transaction);
try
{
SimplefeatureStore.addFeatures(SimpleFeaturecollection);
transaction.commit();
JOptionPane.showMessageDialog(null, “The points have been adden
into shipfile!”);
}
catch
(Exception problem)
{
problem.printStackTrace();
transaction.rollback();
}
finally
{
transaction.close();
}
System.exit(0);
transaction = new
DefaultTransaction(null)，这里的null是可以设置string类型的值的，这个值有什么影响还不清楚，求助大神！
以下是装载数据的代码：
File
SHPfilepath=new File(“E:\\workspace”);
SHPfilepath=new File(“E:\\workspace”);
File
SHPfile = JFileDataStoreChooser.showOpenFile(“shp”, SHPfilepath,
null);
SHPfile = JFileDataStoreChooser.showOpenFile(“shp”, SHPfilepath,
null);
if (SHPfile ==
null)
{
return;
}
FileDataStore store =
FileDataStoreFinder.getDataStore(SHPfile);
String typeName =
store.getTypeNames()[0];
JOptionPane.showMessageDialog(null, “This is the
typeName=”+typeName);
SimpleFeatureSource featureSource =
store.getFeatureSource(typeName);
SimpleFeatureStore SimplefeatureStore = (SimpleFeatureStore)
featureSource;
SimpleFeatureCollection SimpleFeaturecollection = new
ListFeatureCollection(TYPE, features);
Transaction transaction = new DefaultTransaction(null);
SimplefeatureStore.setTransaction(transaction);
try
{
SimplefeatureStore.addFeatures(SimpleFeaturecollection);
transaction.commit();
JOptionPane.showMessageDialog(null, “The points have been adden
into shipfile!”);
}
catch
(Exception problem)
{
problem.printStackTrace();
transaction.rollback();
}
finally
{
transaction.close();
}
System.exit(0);
}
