Question

我有一个SQL查询，它返回DateTime作为其中一个对象。将它添加到JsonArray时出现错误。

堆栈追踪：

我相信错误发生在这里：

  private List<JsonArray> rowDataSeqToJsonArray(com.github.mauricio.async.db.ResultSet set) {
    List<JsonArray> list = new ArrayList<>();
    set.foreach(new AbstractFunction1<RowData, Void>() {
      @Override
      public Void apply(RowData row) {
        list.add(rowToJsonArray(row));
        return null;
      }
    });
    return list;
  }

我的Rowdata看起来像这样：

Some(MutableResultSet(ArrayRowData(, , hphan, 2016-04-26T00:00:00.000-07:00, 1), ArrayRowData(, , hphan, 2016-04-28T00:00:00.000-07:00, 2), ArrayRowData(BXBSVA, BLUE CROSS BLUE SHIELD VIRGINIA, null, 2016-04-26T00:00:00.000-07:00, 1)))

有谁知道如何解决这个问题？

这应该适用于即将发布的3.3版本。但请注意，异步客户端被标记为技术预览，因此存在粗糙的边缘。

如果您需要更多我建议使用jdbc客户端的功能，请说明。虽然性能不是很高，但功能齐全。

Vert.x：包含DateTime的PostgreSql结果未添加到JsonArray
