Gson gson = new GsonBuilder().setDateFormat("yyyy-MM-dd HH:mm:ss").create();
System.out.println(gson.toJson(obj));
System.out.println(obj.toString());
BaseResultVo<PageDataVo<BrowseHistory>> baseResultVo = gson.fromJson(gson.toJson(obj),new TypeToken<BaseResultVo<PageDataVo<BrowseHistory>>>(){}.getType());
PageDataVo<BrowseHistory> pageDataVo = baseResultVo.getData();
return pageDataVo;输出的代码：
{"code":"200","msg":"success","data":{"start":0,"pageSize":1,"curPage":1,"totalPage":3,"totalRows":3,"dataList":[{"id":18,"siteId":0,"subId":1,"ip":"string","docId":1,"docLibId":1,"loginName":"string","createTime":"2018-07-02 19:32:33","updateTime":"2018-07-02 19:32:33"}]}}
{code=200, msg=success, data={start=0, pageSize=1, curPage=1, totalPage=3, totalRows=3, dataList=[{id=18, siteId=0, subId=1, ip=string, docId=1, docLibId=1, loginName=string, createTime=2018-07-02 19:32:33, updateTime=2018-07-02 19:32:33}]}}

注意：

gson.toJson(obj) 此处不能换成obi.tostring()，否则出错，会报日期转换失败的错误
