java类的序列化和局部变量禁止序列化

父类

package SysCommon.util;

import java.io.Serializable;

import SysCommon.util.Tools;


public abstract class IBean implements  Serializable  {
	public String toJson() throws Exception {
		return Tools.gson.toJson(this);
	}
}

子类

package org.jgw.onepai.bean;

import java.util.List;

import android.graphics.Bitmap;

import SysCommon.util.IBean;

public class Article extends IBean 
{
        
        public String CURR_aid;
        
        public String CURR_acronym;
        
        public String CURR_article_name;
        
        
        public String CURR_specification;
        
        public String CURR_unit;
                
        public String CURR_supplier_id;
        
        public String CURR_segregate_id;
        
        public String CURR_brand_id;
        
        public String CURR_origin;
        
        public float CURR_last_entry_price;
        
        public int CURR_duty_paragraph;
        
        public String CURR_status;
        
        public float CURR_retail_price;
        
        public float CURR_member_price;
        
        public String CURR_img;
        
        public String CURR_memo;
        
        public List<Barcode> CURR_barcode ;    
                
        transient public Bitmap img; 
        
        public Brand CURR_brand;
        
}

小结 对象序列化：

1、implements  Serializable
2、某个变量不序列化 transient public Bitmap img
