Question

我想从Spring批处理表中使用JPA和EclipseLink ORM读取数据，这些表似乎不遵循Eclipselink约定

我得到的例外情况如下：

Runtime Exceptions: 
---------------------------------------------------------

java.lang.IllegalArgumentException: Column name BATCH_JOB_EXECUTION.CREATE_TIME does not follow DateTime type convention. Use suffix [_TS] due to conventions.

java.lang.NullPointerException

    ... 124 common frames omitted

日期时间字段存在问题，因为它们不包含TS作为后缀：

@Column(name = "CREATE_TIME")
private DateTime createTime;

是否有任何解决方法或如何关闭此类行为？

我使用java.util.Date而不是org.joda.time.DateTime来解决Dmitry在问题下面的评论中提出的问题

使用JPA和EclipseLink
