java reflects a simple method of traversing entity class attributes and types assigning and getting values

Examples are as follows:

import java.lang.reflect.Field;
import java.lang.reflect.InvocationTargetException;
import java.lang.reflect.Method;
import java.util.Date;

/**
 *  Gets the property name and type of the entity type 
 * @param model  For the entity class 
 * @author kou  Is the incoming parameter 
 */
