public class test {
public static void main(String[] args) throws Exception{

方法三(实体类)：
//java中遍历实体类，获取属性名和属性值
public static void testReflect(Object model) throws Exception{
for (Field field : model.getClass().getDeclaredFields()) {
field.setAccessible(true);
System.out.println(field.getName() + ":" + field.get(model) );
方法四（实体类或拓展类）:
public static void test2(Object obj) {
try {
PropertyUtilsBean propertyUtilsBean = new PropertyUtilsBean();
PropertyDescriptor[] descriptors = propertyUtilsBean.getPropertyDescriptors(obj);
for (int i = 0; i < descriptors.length; i++) {
String name = descriptors[i].getName();
if (!"class".equals(name)) {
System.out.println(name+":"+ propertyUtilsBean.getNestedProperty(obj, name));
} catch (Exception e) {
e.printStackTrace();
