BeanUtils.copyProperties 須要getset方法支持

今天在調用這個方法時，發現屬性沒有映射上，結果一看是model類沒有加上getset方法 `PropertyDescriptor[] targetPds = getPropertyDescriptors(actualEditable); List<String> ignoreList = (ignoreProperties != null ? Arrays.asList(ignoreProperties) : null);

for (PropertyDescriptor targetPd : targetPds) {
		Method writeMethod = targetPd.getWriteMethod();
		if (writeMethod != null && (ignoreList == null || !ignoreList.contains(targetPd.getName()))) {
			PropertyDescriptor sourcePd = getPropertyDescriptor(source.getClass(), targetPd.getName());
			if (sourcePd != null) {
				Method readMethod = sourcePd.getReadMethod();
				if (readMethod != null &&
						ClassUtils.isAssignable(writeMethod.getParameterTypes()[0], readMethod.getReturnType())) {
					try {
						if (!Modifier.isPublic(readMethod.getDeclaringClass().getModifiers())) {
							readMethod.setAccessible(true);
						}
						Object value = readMethod.invoke(source);
						if (!Modifier.isPublic(writeMethod.getDeclaringClass().getModifiers())) {
							writeMethod.setAccessible(true);
						}
						writeMethod.invoke(target, value);
					}
					catch (Throwable ex) {
						throw new FatalBeanException(
								"Could not copy property '" + targetPd.getName() + "' from source to target", ex);
					}
				}
			}
		}
