GSON转换成Long型变为科学计数法及时间格式转换异常的解决方案

直接上工具类了，简单实用

public class GsonUtils {

    private static Gson gson = null;
 static {
 if (gson == null) {
 gson = new GsonBuilder()
  .setDateFormat("yyyy-MM-dd HH:mm:ss")
 .setLongSerializationPolicy(LongSerializationPolicy.STRING)
 .create();
 }
 }

public static String gsonString(Object object) {
 String gsonString = null;
 if (gson != null) {
 gsonString = gson.toJson(object);
 }
 return gsonString;
}

    public static <T> List<T> gsonToList(String gsonString, Class<T> cls) {
 List<T> list = null;
 if (gson != null) {
 list = gson.fromJson(gsonString, new TypeToken<List<T>>() {
 }.getType());
 }
 return list;
 }

}
