示例1: updateSchema
import org.ektorp.AttachmentInputStream; //导入方法依赖的package包/类
@Override
public void updateSchema(JsonNode oldSchema, JsonNode newSchema) {
// store new version of the schema as newest revision of the document
db.update(newSchema);
// prepare old schema as stream
byte[] bytes = jsonNodeToBytes(oldSchema);
InputStream stream = new ByteArrayInputStream(bytes);
String oldRev = oldSchema.get("_rev").textValue();
// create attachment as stream
// id will be revision of old schema
// data will be stored as application/json content type
// note that this also increment revision of the document
AttachmentInputStream data = new AttachmentInputStream(oldRev, stream, "application/json");
String id = newSchema.get("_id").textValue();
db.createAttachment(id, getCurrentRevision(id), data);
try {
data.close();
} catch (IOException ex) {
logger.error(ex);
}
}
示例2: getDocumentByIdAndRev
import org.ektorp.AttachmentInputStream; //导入方法依赖的package包/类
@Override
public JsonNode getDocumentByIdAndRev(String id, String rev) {
String currentRev = getCurrentRevision(id);
JsonNode schema = null;
// current and needed revisions are the same so return current version of the schema
if (currentRev.equals(rev)) {
