Trying to evaluate OrientDB1.7.3 with Document API for our Analytics.
Was able to save all the simple properties along with other class type
properties as simple ones except the List type.
//Pojo to be inserted
public class PurchaseRequest implements Serializable {
private String customerName;
private Address shippingAddress;
private List<Item> items;
}
//Simplified DAO api
public String save(Object entity, String storeName) {
ODocument doc = populateDocument(db, entity, storeName);
db.begin();
doc = doc.save(true);
db.commit();
}
//Util method
private ODocument populateDocument(ODatabaseDocument oDatabaseDocument,
Object entity, String storeName, List<String> excludeKeys)
throws Exception {
ODocument doc = new ODocument(storeName);
BeanInfo beanInfo = Introspector.getBeanInfo(entity.getClass());
for (PropertyDescriptor pd : beanInfo.getPropertyDescriptors()) {
String name = pd.getName();
if (pd.getReadMethod() != null && !"class".equals(pd.getName())) {
Method readMethod = pd.getReadMethod();
Object value = pd.getReadMethod().invoke(entity);
System.out.println("\n name :" + name + " value:"+ value );
doc.field(name, value );
}
}
return doc;
}
Throws an error while saving items as an embedded list.
Appreciated your help.
Cannot serialize the object since it's not implements the
OSerializableStream interface
