TimeStamp日期类型转化成json-蒲公英云

TimeStamp日期类型转化成json

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;
    }
