Spring Batch 5：失败原因：java.time.format.DateTimeParseException：无法在索引 0 处解析文本“日期”

问题描述 投票：0回答：1

最近，我使用 Spring 5.1.2 将我们的应用程序迁移到了 java 17，因此 Spring 批处理也从 v4 迁移到了 v5。

按照指南中所述进行了必要的更改。

但是，在第一次运行期间，Spring框架将开始正确地将数据插入批处理表中，但由于应用程序级别问题（某些crt问题）而失败。

因此，在更正 crt 后，如果我尝试运行该应用程序，则会失败并出现以下错误：

org.springframework.core.convert.ConversionFailedException：无法将值 [date] 从类型 [java.lang.String] 转换为类型 [java.util.Date]

原因：java.time.format.DateTimeParseException：无法在索引 0 处解析文本“日期”

下面的查询在 Spring Batch 中使用： https://github.com/spring-projects/spring-batch/wiki/Spring-Batch-5.0-Migration-Guide?secureweb=Teams&secureweb=Teams&secureweb=Teams#column-change-in-batch_job_execution_params

选择作业_执行_ID、参数_名称、参数_类型、参数_值、识别 来自 BDB_DBA.BATCH_JOB_EXECUTION_PARAMS 哪里 JOB_EXECUTION_ID = ?

BATCH_JOB_EXECUTION_PARAMS 表的图像： 在此输入图片描述

无法理解根本原因是什么，因为我们没有手动更新任何内容。 Spring 批处理框架会处理一切。

对于表创建： https://github.com/spring-projects/spring-batch/blob/main/spring-batch-core/src/main/resources/org/springframework/batch/core/schema-oracle.sql

即使之前的作业处于失败状态，它也应该正常工作

    <property name="dataSource" ref="dataSourceHikari"/>

在您共享的屏幕截图中，我看到参数

runTime
的值是字符串文字
date
。这意味着作业是用像 
runTime=date
这样的参数启动的，这显然是不正确的。

我建议您将参数类型从 

java.lang.String
更改为 
java.time.LocalDate
并在启动时传递正确的日期值。

Spring Batch 默认情况下已经注册了一个 

LocalDate
到/来自 
String
转换器。
