java 反射得到private 类型的字段

package demo;

public class searchbean {

	private int id;
	private String goodsname;
	private double price;
	public String fieldsdemo;
	public int getId() {
		return id;
	}
	public void setId(int id) {
		this.id = id;
	}
	public String getGoodsname() {
		return goodsname;
	}
	public void setGoodsname(String goodsname) {
		this.goodsname = goodsname;
	}
	public double getPrice() {
		return price;
	}
	public void setPrice(double price) {
		this.price = price;
	}
	
}

用getDeclaredFields就能得到private 和public protend protected 的字段
如果用c.getFields();只能得到public类型的属性

Class c =Class.forName("demo.searchbean");
		Field[] f =c.getDeclaredFields();
		for (Field fd : f) {
			System.out.println(fd.getName());
		}
