一、相关环境以及准备
二、arcengine连接sde
1、可以现在自己电脑上的arcgis上连接下sde试试看能不能连上，如果自己的arcgis都连不上sde，代码里肯定也连不上。
2、arcengine连接sde的相关代码如下：
/**
* 连接sde 并返回连接sde后的工作空间
*
* @return
* @throws IOException
*/
public static Workspace connectSde() throws IOException {
initializeArcGISLicenses();
Workspace workspace = null;
IPropertySet pPropset = new PropertySet();
// IWorkspaceFactory pWorkspaceFact = new SdeWorkspaceFactory();
SdeWorkspaceFactory pWorkspaceFact = new SdeWorkspaceFactory();
// Populate the property set with the connection parameters
pPropset.setProperty("SERVER", "10.10.1.161");
// propSet.setProperty("INSTANCE", "sde:postgresql:10.10.1.178,5432");
pPropset.setProperty("INSTANCE", "sde:oracle11g:10.10.1.258/ORCL");
pPropset.setProperty("DATABASE", "orcl");
pPropset.setProperty("USER", "data_check");
pPropset.setProperty("PASSWORD", "123456");
pPropset.setProperty("VERSION", "sde.DEFAULT");
log.info("数据源数据库为：10.10.1.258,1521");
// Open the ArcSDE workspace using the connection PropertySet
// workspace = pWorkspaceFact.open(pPropset, 0);
workspace = new Workspace(pWorkspaceFact.open(pPropset, 0));
return workspace;
}
三、先在sde里创建图层数据表（sde里已有图层数据表的可以忽略）
/**
* 在 sde 里创建 table
*
* @param gdbPath
* @param FcName 图层名
* @param pWorkspace 连接sde的工作空间
* @param tableName 生成的表明
*/
public static void createTable(String gdbPath, String FcName, IWorkspace pWorkspace, String tableName) throws IOException {
initializeArcGISLicenses();
try {
//获取gdb里的featureClass
//创建 gdb工作空间
FileGDBWorkspaceFactory pFileGDBWorkspaceFactoryClass = new FileGDBWorkspaceFactory();
IFeatureWorkspace pFeatureWorkspace = (IFeatureWorkspace) pFileGDBWorkspaceFactoryClass.openFromFile(gdbPath, 0);
//获取 gdb中某个图层的 FeatureClass对象
IFeatureClass pFeatureClass = pFeatureWorkspace.openFeatureClass(FcName);
// IGeoDataset pGeoDataset = (IGeoDataset) pFeatureClass;
//featureClass的字段
IFields fields = pFeatureClass.getFields();
//连接sde库
if (pWorkspace != null) {
IFeatureWorkspace featureWorkspace = (IFeatureWorkspace)pWorkspace;
//创建新featureclass
IFeatureClass pFCls = featureWorkspace.createFeatureClass(tableName, fields, null, null,
pFeatureClass.getFeatureType(), pFeatureClass.getShapeFieldName(), "");
}
} catch (Exception ex) {
ex.printStackTrace();
}
}
四、将数据从gdb文件写入sde
/**
* 将gdb里某个图层的数据全部存入sde的某个table中
* @param gdbPath
* @param layerCode gdb里图层名称
* @param tableName sde里的表名称
* @param startId sde表开始存的id
* @param primaryKey sde表的主键
* @throws IOException
*/
public static void dataToTable(String gdbPath, String layerCode, String tableName , Integer startId ,
String primaryKey) throws IOException {
initializeArcGISLicenses();
//获取 连接sde的 IFeatureClass 对象
Workspace workspace = connectSde();
IFeatureClass iFeatureClass = workspace.openFeatureClass("data_check." + tableName);
//获取 gdb里图层的 featureClass 对象
FeatureVo fcAndF = getFCAndF(gdbPath, layerCode);
IFeatureClass featureClass = fcAndF.getFeatureClass();
// IFeatureCursor featureCursor = featureClass.IFeatureClass_insert(true);
IQueryFilter queryFilter = new QueryFilter();
IFeatureCursor search = featureClass.search(queryFilter, true);
//获取 IFeature对象
IFeature pFeature = null;
while ((pFeature = search.nextFeature()) != null) {
//将数据一条一条存进sde
gdbToSde(iFeatureClass, pFeature , startId , primaryKey);
}
search.flush();
}
/**
* 将 gdb文件里的一条数据写进sde的table里(sde中的table已存在)
*
* @param pFeatureClass 连接数据库里的table对象
* @param pFeature 单条数据，也就是单个图版
* @param startId sde表开始存的id
* @param primaryKey sde表的主键
* @return
* @throws IOException
*/
public static void gdbToSde(IFeatureClass pFeatureClass, IFeature pFeature , Integer startId ,
String primaryKey) throws IOException {
initializeArcGISLicenses();
// IFeatureClass rFeatureClass = Erase(pFeatureClass, pFeature);
IFeatureCursor featureCursor = pFeatureClass.IFeatureClass_insert(true);
IFeatureBuffer feaBuffer = pFeatureClass.createFeatureBuffer();
IField fld = new Field();
IFields flds = pFeature.getFields();
if(startId == 0){
for (int i = 0; i < flds.getFieldCount(); i++) {
fld = flds.getField(i);
String fldname = fld.getName();
int index = feaBuffer.getFields().findField(fldname);
if (index != -1 && index != 0) {
feaBuffer.setValue(index, pFeature.getValue(i));
}
}
feaBuffer.setShapeByRef(pFeature.getShape());
featureCursor.insertFeature(feaBuffer);
featureCursor.flush();
}else {
for (int i = 0; i < flds.getFieldCount(); i++) {
fld = flds.getField(i);
String fldname = fld.getName();
int index = feaBuffer.getFields().findField(fldname);
if (index != -1 && index != 0) {
if(fldname.equals(primaryKey)){
feaBuffer.setValue(index, ++startId);
}else {
feaBuffer.setValue(index, pFeature.getValue(i));
}
}
}
feaBuffer.setShapeByRef(pFeature.getShape());
featureCursor.insertFeature(feaBuffer);
// featureCursor.flush();
}
}
/**
* 获取 IFeatureWorkspace 和 IFeatureClass 和 IFeature 对象
*
* @param gdbPath
* @param layerCode
* @return
*/
public static FeatureVo getFCAndF(String gdbPath, String layerCode) throws IOException {
initializeArcGISLicenses();
//featureVo 就是个实体类，封装了IFeatureWorkspace 与 IFeatureClass
FeatureVo featureVo = new FeatureVo();
//创建 gdb工作空间
FileGDBWorkspaceFactory pFileGDBWorkspaceFactoryClass = new FileGDBWorkspaceFactory();
IFeatureWorkspace pFeatureWorkspace = (IFeatureWorkspace) pFileGDBWorkspaceFactoryClass.openFromFile(gdbPath, 0);
//获取 gdb中某个图层的 FeatureClass对象
IFeatureClass pFeatureClass = pFeatureWorkspace.openFeatureClass(layerCode);
featureVo.setFeatureWorkspace(pFeatureWorkspace);
featureVo.setFeatureClass(pFeatureClass);
return featureVo;
}
dataToTable这个方法里有个参数是gdb图层名称，我上一篇文章有如何获取gdb里图层名称的方法
