Entity classes are quickly mapped to Map

/**

 * @param obj the entity class that needs to get data
 * @param builder The Builder that needs to insert data
 * @throws Exception
 */
public static void entityGet(Object obj, Builder builder) throws Exception {
	Field[] fields = obj.getClass().getDeclaredFields();
	for (int j = 0; j < fields.length; j++) {
		Field field = fields[j];
		PropertyDescriptor pd = new PropertyDescriptor(field.getName(), obj.getClass());
		Method getMethod = pd.getReadMethod();
		if (getMethod != null) {
			if ("class java.util.Date".equals(field.getType().toString())
					&& getMethod.invoke(obj) != null) {
				builder.addField(field.getName(),
						new SimpleDateFormat("yyyy-MM-dd").format((Date) getMethod.invoke(obj)));
			} else if ("class java.lang.Integer".equals(field.getType().toString())
					&& getMethod.invoke(obj) != null) {
				builder.addField(field.getName(), Integer.toString((int) getMethod.invoke(obj)));
			} else {
				if (getMethod.invoke(obj) != null) {
					builder.addField(field.getName(), (String) getMethod.invoke(obj));

	}
}

The reflection mechanism was used for entity class mapping at the beginning, but it was found that the speed was not fast enough. Later, BeanMap was used for mapping, and the speed was doubled.
