jasper 在 excel 中显示错误的日期时间答案

【问题标题】：Wrong datetime showing in excel by jasperjasper 在 excel 中显示错误的日期时间
【发布时间】：2018-05-02 15:44:22
【问题描述】：

我不确定为什么会发生这种情况，但时区和所有设置都是正确的，但数据库中的日期时间没有反映在报告中并显示不同的内容。

注意：此 excel 报告正在由 jasper 报告工具导出。

日期在 oracle 数据库中：

18 年 1 月 2 日 11.22.09 下午

日期在 excel 报告中

2018 年 1 月 2 日下午 6:22:09

这有什么问题我真的不知道。

但从 excel 报告的角度以及 db 的角度来看，时区是正确的。并且时区仅为“美国/东部”。

出现错误的列是这些字段：

inspectionQCCompleteDate,inspectionCompleteDate

请有人帮我解决这个问题。

【问题讨论】：

@AlexK 我删除了多余的代码并在底部添加了更多描述。

标签： java datetime timezone jasper-reports

【解决方案1】：

要解决日期时间差异，请在 jrxml 中为 inspectionQCCompleteDate 和 inspectionCompleteDate 列定义 textFieldExpression，如下所示：

 <textFieldExpression class="java.util.Date">
    <![CDATA[$P{SIMPLE_DATE_FORMAT_WITH_TIME_ZONE}.parse($P{SIMPLE_DATE_FORMAT_WITH_TIME_ZONE}.format($F{inspectionQCCompleteDate}))]]>
</textFieldExpression>


<textFieldExpression class="java.util.Date">
    <![CDATA[$P{SIMPLE_DATE_FORMAT_WITH_TIME_ZONE}.parse($P{SIMPLE_DATE_FORMAT_WITH_TIME_ZONE}.format($F{inspectionCompleteDate}))]]>
</textFieldExpression>

【讨论】：

你太棒了兄弟。太感谢了。你让我开心。
