Question

我正在使用rest api，而我遇到了这个问题

java.lang.IndexOutOfBoundsException: Invalid time zone indicator '0'

基本上我是使用Gson将Json转换为我的班级

Gson gson = new Gson();
    MyResponse myResponse = gson.fromJson(responseService.getNumber(id), MyResponse.class);

但是我像这样在json中有一个日期

 "date": 1375412400000

如何在日期上转换为模型类？要转换并显示例如02/25/2018吗？

MyResponse.class

public class MyResponse {


    List<Dados> dados;


    public List<Dados> getDados() {
        return dados;
    }

    public void setDados(List<Dados> dados) {
        this.dados = dados;
    }


}

ResponseService.class

public interface ResponseService {

    @GetMapping("/search/rg/{rg}")
    String getDados(@PathVariable("rg") String rg);

}

Dados.Class

public class Dados {



@JsonFormat(shape = JsonFormat.Shape.STRING,pattern="dd/MM/yyyy",locale = "pt-BR", timezone = "Brazil/East")
@DateTimeFormat(pattern = "dd/MM/yyyy")
@Temporal(TemporalType.DATE)
Date data;




String codigo;

String estado;


String  cidade;

String oriundo;


...gets and setters




}

我找到了解决方案。首先，我必须设定日期

ErrorActivity

在我必须创建一个类以反序列化日期之后

GsonBuilder gsonBuilder = new GsonBuilder();
gsonBuilder.setDateFormat("M/d/yy hh:mm a");

然后我在gsonbuilder中使用了我的课程

import java.lang.reflect.Type;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.TimeZone;

import com.google.gson.JsonDeserializationContext;
import com.google.gson.JsonDeserializer; 
import com.google.gson.JsonElement;
import com.google.gson.JsonParseException;

public class DateDeserializer implements JsonDeserializer<Date> {

  @Override
  public Date deserialize(JsonElement element, Type arg1, 
  JsonDeserializationContext arg2) throws JsonParseException {
    String date = element.getAsString();

    SimpleDateFormat formatter = new SimpleDateFormat("M/d/yy hh:mm a");
    formatter.setTimeZone(TimeZone.getTimeZone("UTC"));

    try {
        return formatter.parse(date);
    } catch (ParseException e) {
        System.err.println("Failed to parse Date due to:", e);
        return null;
    }
  }
}

JSON毫秒日期到Java日期
