我有以下格式的日期: 2010-03-01T00:00:00-08:00
我在它上面抛出了以下SimpleDateFormats来解析它:
private static final SimpleDateFormat[] FORMATS = {
new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ssZ"), //ISO8601 long RFC822 zone
new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ssz"), //ISO8601 long long form zone
new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss"), //ignore timezone
new SimpleDateFormat("yyyyMMddHHmmssZ"), //ISO8601 short
new SimpleDateFormat("yyyyMMddHHmm"),
new SimpleDateFormat("yyyyMMdd"), //birthdate from NIST IHE C32 sample
new SimpleDateFormat("yyyyMM"),
new SimpleDateFormat("yyyy") //just the year
};
我有一个方便的方法,使用这样的格式:
public static Date figureOutTheDamnDate(String wtf) {
if (wtf == null) {
return null;
}
Date retval = null;
for (SimpleDateFormat sdf : FORMATS) {
try {
sdf.setLenient(false)
retval = sdf.parse(wtf); …我有一个Java类,用户:
public class User
{
int id;
String name;
Timestamp updateDate;
}
我收到一个包含来自Web服务的用户对象的JSON列表:
[{"id":1,"name":"Jonas","update_date":"1300962900226"},
{"id":5,"name":"Test","date_date":"1304782298024"}]
我试图编写一个自定义反序列化器:
@Override
public User deserialize(JsonElement json, Type type,
JsonDeserializationContext context) throws JsonParseException {
return new User(
json.getAsJsonPrimitive().getAsInt(),
json.getAsString(),
json.getAsInt(),
(Timestamp)context.deserialize(json.getAsJsonPrimitive(),
Timestamp.class));
}
但我的解串器不起作用.如何为Gson编写自定义JSON反序列化器？
我有一些对象类对象的json字符串表示
public class SMPBBaseObjectsList {
public ArrayList<Object> data = new ArrayList<>();
public Integer count;
public Integer limitFrom;
public Integer limitTo;
public Boolean hasMore;
public String dataItemsClass;
}
我有json
{ "classItem": "smpb.utility.classes.SMPBBaseObjectsList", "dataItemsClass": "smpb.base.classes.SMPBUser", "dataSliceCode": "012013", "数据":[{ "ID":1374046117510970000"名称 ":" Test3" 的, "classItem": "smpb.base.classes.SMPBUser", "dataSliceCode": "012013"}], "过滤器":{ "的OrderItems":[], "filterItems":[]} }
我尝试解析这个json并使用下一个代码创建我的类的对象:
String json = "{\"classItem\":\"smpb.utility.classes.SMPBBaseObjectsList\",\"dataItemsClass\":\"smpb.base.classes.SMPBUser\",\"dataSliceCode\":\"012013\",\"data\":[{\"id\":1374046117510970000,\"Name\":\"Test3\",\"classItem\":\"smpb.base.classes.SMPBUser\",\"dataSliceCode\":\"012013\"}],\"filter\":{\"orderItems\":[],\"filterItems\":[]}}";
SMPBBaseObjectsList list = new GsonBuilder().create().fromJson(json, SMPBBaseObjectsList.class);
System.out.println("BEFORE:" + json);
System.out.println("AFTER: " + list);
系统输出:
BEFORE: {"classItem":"smpb.utility.classes.SMPBBaseObjectsList","dataItemsClass":"smpb.base.classes.SMPBUser","dataSliceCode":"012013","data":[{ "id":1374044905885298000, "名称": "Test3的", "classItem": "smpb.base.classes.SMPBUser", "dataSliceCode": "012013"}], "过滤器":{ "的OrderItems":[], "filterItems":[ …
