我以这种格式从服务器返回JSON:
{
"StartDate": "/Date(1451593800000)/",
"EndDate": "/Date(1483216200000)/"
}
在我的POJO中:
public class Data {
java.util.Date startDate;
java.util.Date endDate;
}
我的Gson对象:
private final Gson gson = new GsonBuilder()
.serializeNulls()
.setFieldNamingPolicy(FieldNamingPolicy.UPPER_CAMEL_CASE)
.create();
当我想解析这个JSON时,我得到了这个错误:
Unparseable date: "/Date(1483216200000)/" (at offset 0)
使用Gson在Android中解析此类JSON的正确方法是什么?

我做过这样的事情,创建一个Date Serializer并将其注册到GsonBuilder。
import java.lang.reflect.Type;
import java.util.Date;
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 data = element.getAsString();
data = data.replace("/Date(", "");
data = data.replace(")/", "");
try {
return new Date(Long.parseLong(data));
} catch (Exception e) {
System.out.println("Failed to parse Date due to:");
return null;
}
}
}
注册Gson Builder
Gson gson = new GsonBuilder().serializeNulls()
.setFieldNamingPolicy(FieldNamingPolicy.UPPER_CAMEL_CASE)
.registerTypeAdapter(Date.class, new DateDeserializer()).create();
