如何在JSON中轉換日期
[英]How to convert date in json
問題描述
我是json的新手。 我正在使用其中存在datetime字段的mysql查詢。我想將查詢結果轉換為json。但是對於datetime字段，我將該字段強制轉換為僅正確執行date.query並提供正確的輸出。但是當我嘗試將此結果轉換為json，其給出的錯誤與日期時間字段相關。 要在json中轉換的類是。
package com.helical.efw.json;
import java.util.List;
import java.util.Map;
import net.sf.json.JSONObject;
public class ConvertJson {
public String CommonJson(Map<String,? extends List<?>> commonList)
{
String jsonString;
System.out.println("in json locationId List=======jjjj==========");
JSONObject json = new JSONObject();
json.accumulateAll(commonList);
jsonString=json.toString();
System.out.println(json.toString());
return jsonString;
}
}
觸發查詢的方法：
public List<Map<String,Object>> getLastSevenDaysStageExecutionDetail()
{
System.out.println("I am in getLastStageExecutionDetail=========");
Session session = HibernateUtil.getSessionFactory().getCurrentSession();
session.beginTransaction();
Query query;
List<Map<String,Object>> aliasToValueMapList=null;
try{
String d1="2013-12-30";
String d2="2013-12-31";
query =session.createSQLQuery("SELECT cast(moment as date) as dated, timestampdiff(second,moment, end_time) as t FROM efw_db.efw_job_time where moment between '"+d1+"' and '"+d2+"' group by cast(moment as date);");
query.setResultTransformer(AliasToEntityMapResultTransformer.INSTANCE);
aliasToValueMapList=query.list();
System.out.println(aliasToValueMapList.toString());
}catch(Exception e) {
e.printStackTrace();
}
return aliasToValueMapList;
}
Error is:
HTTP Status 500 - java.lang.reflect.InvocationTargetException
type Exception report
message java.lang.reflect.InvocationTargetException
description The server encountered an internal error that prevented it from fulfilling this request.

您始終可以提供自己的JsonValueProcessor來實現所需的編碼。 我決定使用getTime()方法將日期編碼為自格林尼治標准時間1970年1月1日00:00:00起經過的毫秒數。
這是一些示例代碼：
JsonConfig config = new JsonConfig();
config.registerJsonValueProcessor(java.util.Date.class, new JsonValueProcessor() {
@Override
public Object processArrayValue(Object value, JsonConfig jsonConfig) {
Date[] dates = (Date[])value;
Long[] result = new Long[dates.length];
for (int index = 0; index < dates.length; index++) {
result[index] = dates[index].getTime();
}
return result;
}
@Override
public Object processObjectValue(String key, Object value, JsonConfig jsonConfig) {
Date date = (Date)value;
return date.getTime();
}
});
然后，您可以創建一個JSONObject ，如下所示：
Map<String, Object> data = new HashMap<String, Object>();
data.put("myDate", new Date());
JSONObject jsonObject = (JSONObject) JSONSerializer.toJSON( data, config );

在JSON-Lib中，有一個JsDateJsonBeanProcessor，但是它可以轉換為
{
"minutes": 13,
"seconds": 14,
"hours": 12,
"month": 5,
"year": 2007,
"day": 17,
"milliseconds": 150
}
Jackson JSON Processor更靈活，默認情況下它以毫秒為單位寫入日期，但是您也可以將其配置為使用ISO-8601格式，請參見http://wiki.fasterxml.com/JacksonFAQDateHandling

這個答案是針對Gson的Java的Google Json庫。
首先創建一個類型轉換器類，如下所示
https://sites.google.com/site/gson/gson-type-adapters-for-common-classes-1
假設您使用的是joda time，並且類型轉換器類名為DateTimeTypeConverter，然后像這樣創建Gson對象
GsonBuilder builder = new GsonBuilder();
builder.registerTypeAdapter(DateTime.class, new DateTimeTypeConverter());
Gson gson = builder.create();
我以這種方式工作。
