转换LocalDate.MAX为日期 [英] Convert LocalDate.MAX to Date

问题描述

我们正在使用Spring Data JPA访问Derby-DB.时间值定义为java.time.LocalDate(java 8时间api).现在，Spring Data附带了org.springframework.data.convert.Jsr310Converters.LocalDateToDateConverter，可将LocalDate转换为java.util.Date，因为据我所知，JPA规范到目前为止不支持LocalDate.

We are using Spring Data JPA to access a Derby-DB. Temporal values are defined as java.time.LocalDate (java 8 time api). Spring Data now is shipped with a org.springframework.data.convert.Jsr310Converters.LocalDateToDateConverter to convert LocalDate to java.util.Date, since - far as I know - JPA specification does not support LocalDate so far.

现在将LocalDate.MAX转换为Date时出现问题，导致以下异常(已剥离):

We now have an issue when converting a LocalDate.MAX to Date, resulting in the following exception (stripped):

Caused by: java.lang.IllegalArgumentException: java.lang.ArithmeticException: long overflow

还有谁遇到过这个问题并提出了解决这个问题的建议吗?

Anyone who also faced this issue and have a suggestion to overcome this issue?

推荐答案

java.util.Date不支持将来的日期.参见其 javadoc :

java.util.Date doesn't support dates that far into the future. See its javadoc :

Instant 可以存储点与

Instant can store points on the time-line further in the future and further in the past than Date.

因此，您将必须定义自己的JPA AttributeConverter，并且可能将其存储为String或其他类型

Consequently you would have to define your own JPA AttributeConverter and maybe store it as a String, or some other type
