I use apache-commons-beanutils DynaBean class in order to fetch rows from a database and to handle them outside of the mysql function.
is there a way to convert a DynaBean to a List without iterating through each row and manually creating the l开发者_JAVA百科ist ?
thanks!
so far I didn't get any answers so I wrote the function that iterates through the rows and creates an ArrayList of HashMap type (String, Object).
public ArrayList<HashMap<String,Object>> convertDynaBeanListToArrayList(List<DynaBean> theList) {
ArrayList<HashMap<String,Object>> result = new ArrayList<HashMap<String,Object>>();
DynaProperty[] dynaProperties = null;
for (Integer i=0;i<theList.size();i++) {
DynaBean row = theList.get(i);
HashMap<String,Object> resultRow=new HashMap<String,Object>();
// each raw got the same column names, no need to fetch this for every line
if (dynaProperties == null) {
dynaProperties = row.getDynaClass().getDynaProperties();
}
for (Integer j=0;j<dynaProperties.length;j++) {
String columnName=dynaProperties[j].getName();
resultRow.put(columnName, row.get(columnName));
}
result.add(resultRow);
}
return result;
}
