### 1. 新建处理timestamp类型的处理类 ###

import java.text.SimpleDateFormat;
    	import java.util.Date;
    	 
    	import net.sf.json.JsonConfig;
    	import net.sf.json.processors.JsonValueProcessor;
    	 
    	/**
    	 * 将timestamp转化成json
    	 */
    	public class TimestampProcessor implements JsonValueProcessor{
    	 
    		private String format = "yyyy-MM-dd hh:mm:ss";//自定义时间格式化的样式
    		public TimestampProcessor() {
    			super();
    			// TODO Auto-generated constructor stub
    		}
    		
    		public TimestampProcessor(String format) {
    			this.format = format;
    		}
    	 
    		public Object processArrayValue(Object arg0, JsonConfig arg1) {
    			// TODO Auto-generated method stub
    			return arg0;
    		}
    		
    		/**
    		 * 处理对象的值
    		 *  str 这个参数是当前需要处理的属性名
    		 */
    		public Object processObjectValue(String str, Object obj, JsonConfig arg2) {
    			// TODO Auto-generated method stub
    			String ret = "";
    			if(obj instanceof java.sql.Timestamp){
    				SimpleDateFormat sdf = new SimpleDateFormat(format);
    				ret = sdf.format(((Date) obj).getTime());
    			}
    			return ret;
    		}
    	 
    	}

### 2. 将含timestamp的实体类转化成json ###

/**
    	 * 将timestamplist转换成String字符串
    	 * 日期为java.sql.Timestamp类型
    	 * @param roads list对象
    	 * @param jsonConfig date属性转换的模板
    	 * @return list对象对应的字符串
    	 */
    	@SuppressWarnings("rawtypes")
    	public String listTimeStampToJsonString(List objs){
    		JsonConfig jsonConfig = new JsonConfig();                                                          
    		jsonConfig.registerJsonValueProcessor(java.sql.Timestamp.class, new TimestampProcessor ("yyyy-MM-dd HH:mm:ss"));
    		JSONArray json=this.listToJSONArray(objs, jsonConfig);
    		String result=this.jsonArrayToJsonString(json);
    		return result;
    	}
