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;
    }

}
