我目前正在here举例，将我的public class APIOperationsManager {
private static APIOperationsManager instance = null;
private Vector<Operation> operations;
private int currentOperationId;
private static final Logger log = LoggerFactory.getLogger(Application.class);
protected APIOperationsManager() {}
public static APIOperationsManager getInstance() {
if(instance == null) {
synchronized(APIOperationsManager.class) {
if(instance == null) {
instance = new APIOperationsManager();
instance.operations = new Vector<Operation>();
instance.currentOperationId = 1;
}
}
}
return instance;
}
public synchronized int registerNewOperation(OpStatus status) {
cleanOperationsList();
currentOperationId = currentOperationId + 1;
Operation newOperation = new Operation(currentOperationId, status);
operations.add(newOperation);
log.info("Registered new Operation to watch: " + newOperation.toString());
return newOperation.getId();
}
public synchronized Operation getOperation(int id) {
for(Iterator<Operation> iterator = operations.iterator(); iterator.hasNext();) {
Operation op = iterator.next();
if(op.getId() == id) {
return op;
}
}
Operation notFound = new Operation(-1, OpStatus.INTERNAL_ERROR);
notFound.setCrated(null);
return notFound;
}
public synchronized void updateOperationStatus (int id, OpStatus newStatus) {
iteration : for(Iterator<Operation> iterator = operations.iterator(); iterator.hasNext();) {
Operation op = iterator.next();
if(op.getId() == id) {
op.setStatus(newStatus);
log.info("Updated Operation status: " + op.toString());
break iteration;
}
}
}
public synchronized void updateOperationMessage (int id, String message) {
iteration : for(Iterator<Operation> iterator = operations.iterator(); iterator.hasNext();) {
Operation op = iterator.next();
if(op.getId() == id) {
op.setMessage(message);
log.info("Updated Operation status: " + op.toString());
break iteration;
}
}
}
private synchronized void cleanOperationsList() {
Date now = new Date();
for(Iterator<Operation> iterator = operations.iterator(); iterator.hasNext();) {
Operation op = iterator.next();
if((now.getTime() - op.getCrated().getTime()) >= Constants.MIN_HOLD_DURATION_OPERATIONS ) {
log.info("Removed operation from watchlist: " + op.toString());
iterator.remove();
}
}
}
}
映射到自定义ResultSet。我已经测试了Object，看起来该对象需要setter才能工作。有没有办法像BeanUtils.setProperty()那样映射值？我不想拥有公共制定者。
