阿錄幫幫忙—JSON將Date轉String

一，應用類：

import java.util.Date;

import net.sf.json.JSON;
import net.sf.json.JSONArray;
import net.sf.json.JsonConfig;

	public void loadNotice() throws IOException {
		List<ContentTable> notices = contentTableService.getContentTables(
				"通知公告", 1, null, "0", 1, 5);
		JsonConfig cf=new JsonConfig();
		cf.registerJsonValueProcessor(Date.class,
				new JsonDateValueProcessor("yy-MM"));
		JSONArray ja = JSONArray.fromObject(notices, cf);
		writeText(ja.toString());
	}

二，轉換類：

package com.sofmit.framework.util;

import java.text.SimpleDateFormat;
import java.util.Date;

import net.sf.json.JsonConfig;
import net.sf.json.processors.JsonValueProcessor;

public class JsonDateValueProcessor implements JsonValueProcessor {

	 /**
     * datePattern
     */
    private String datePattern; 
    public JsonDateValueProcessor(){
    	this.datePattern="yyyy-MM-dd hh:mm:ss";
    }
    public JsonDateValueProcessor(String formate){
    	this.datePattern=formate;
    }
	@Override
	public Object processArrayValue(Object value, JsonConfig config) {
		System.out.println("arrty==	"+value);
		 return process(value); 
	}

	@Override
	public Object processObjectValue(String key, Object value, JsonConfig config) {
		System.out.println("object==	"+value);
		return process(value); 
	}
	 /**
     * process
     * @param value
     * @return
     */
    private Object process(Object value) {
    	System.out.println(value+"===test");
        try {
            if (value instanceof Date) {
                SimpleDateFormat sdf = new SimpleDateFormat(datePattern);
                return sdf.format((Date) value);
            }
            return value == null ? "" : value.toString();
        } catch (Exception e) {
            return "";
        }

    }

    /**
     * @return the datePattern
     */
    public String getDatePattern() {
        return datePattern;
    }

    /**
     * @param pDatePattern the datePattern to set
     */
    public void setDatePattern(String pDatePattern) {
        datePattern = pDatePattern;
    } 

}
