请尝试以下操作：

import java.beans.BeanInfo;
import java.beans.Introspector;
import java.beans.PropertyDescriptor;

LabOrder order = new LabOrder();// Instantiation of the bean.
LabOrder order = Introspector.getBeanInfo(LabOrder.class);
  for (PropertyDescriptor propertyDesc : order.getPropertyDescriptors()) {
      String propertyName = propertyDesc.getName();
      Object value = propertyDesc.getReadMethod().invoke(order);
      System.out.println(propertyName);
      System.out.println(value);
  }

你应该使用反射。这将帮助您：

ClassABC abc = new ClassABC();
for (Field field : abc.getClass().getDeclaredFields()) {
    field.setAccessible(true);
    String name = field.getName();
    Object value = field.get(abc);
    System.out.printf("%s: %s%n", name, value);
}

可以使用反射迭代对象的字段：

Field[] fields = obj1.getClass().getDeclaredFields();

for (Field field : fields) {
    field.setAccessible(true);
    String name = field.getName();
    Object value = field.get(obj1);
    if (value != null) {
        System.out.println(name + " = " + value);
    }
}
