package com.px.util;import java.sql.Timestamp;import java.text.SimpleDateFormat;import net.sf.json.JsonConfig;import net.sf.json.processors.JsonValueProcessor;import java.util.Date;/** * JSONArray对日期类型的按指定格式转换的实现 * * @author liyulin lyl010991@126.com * @version 1.0 2015-03-17 */public class DateJsonValueProcessor implements JsonValueProcessor {private String formate;public DateJsonValueProcessor() {this.formate = "yyyy-MM-dd hh:mm:ss";}public DateJsonValueProcessor(String formate) {this.formate = formate;}public Object processArrayValue(Object value, JsonConfig jsonConfig) {return null;}public Object processObjectValue(String key, Object value, JsonConfig jsonConfig) {if (value instanceof Date || value instanceof Timestamp) {String str = new SimpleDateFormat(this.formate).format((Date) value);return str;}return null;}public String getFormate() {return formate;}public void setFormate(String formate) {this.formate = formate;}}2、处理JsonConfig jf = new JsonConfig(); jf.registerJsonValueProcessor(java.sql.Timestamp.class, new DateJsonValueProcessor()); jf.registerJsonValueProcessor(java.util.Date.class, new DateJsonValueProcessor()); JSONArray.fromObject(ssypList, jf).toString();
，比天才难得，许多天赋差的人经过过勤学苦练也取得了很大的成功。
