我是索尔的新手。我成功索引了一些数据,但在将date属性传递给适当的solr字段后,我收到了一个异常:
我正在传递字符串“15.06.2011 13:51:41”,这是像德国这样的国家的常见日期格式。然而,经过一些谷歌搜索我发现,Solr希望日期是UTC格式。
我的具体问题是: 我可以在Solr的某个时刻将格式转换为UTC吗?这是DateFormatTransformer的情况,还是最初必须以正确的格式传递它?
编辑:我没有使用DataImportHandler。我通过将数据直接传递给Solr来使用DirectUpdateHandler2。因为它被称为“直接更新”,我在那里转换任何东西的机会都很糟糕吗?
对于记录,我得到的例外是:

答案 0 :(得分:22)
根据Solr DateField documentation,此格式是必需的:
日期字段的格式应为1995-12-31T23:59:59Z后面的“Z”表示UTC时间并且是强制性的(有关UTC的说明,请参见下文)。允许使用可选的小数秒,只要它们不以尾随0结尾(但是将忽略超过毫秒的任何精度)。所有其他部分都是强制性的。
唯一的选择是在将日期发送到Solr之前对其进行转换。如果您正在使用DataImportHandler,则可以在该上下文/进程中使用。
