hibernate中的Java 8 LocalDate错误地映射到TIMESTAMP [英] Java 8 LocalDate in hibernate wrongly mapped to TIMESTAMP

问题描述

我使用Spring boot 1.4.2，它带来了hibernate 5.0.11（JPA 2.1）。
我想在我的实体中使用Java 8时间类，并且包含 hibernate-java8 。

  @Entity 
 @Table（name =my_alarms_timeline，indexes =>我的实体定义了一个LocalDate字段。 {...}）
 public class MyAlarm {
 ... 
 @Column（name =validity_date）
 @NotNull 
 Private LocalDate validityDate; 
} 
  

我希望这可以映射到我的H2数据库中的DATE。 p>

在我的数据库中，我声明这是 validity_date DATE NOT NULL，。

当我尝试运行测试时，出现以下错误：
[INFO]造成者：org.hibernate.tool.schema.spi.SchemaManagementException：模式验证：错误表[my_alarms_timeline]中的[validity_date]列中遇到的列类型;找到[date（Types＃DATE）]，但期待[timestamp（Types＃TIMESTAMP）]

令我吃惊的是，如果我改变DB定义为 validity_date TIMESTAMP NOT NULL，我得到错误

由org .hibernate.tool.schema.spi.SchemaManagementException：模式验证：在表[my_alarms_timeline]中的列[validity_date]中遇到错误的列类型;找到[timestamp（Types＃TIMESTAMP）]，但期待[date（Types＃DATE）]

这只是上一个。

我也尝试过使用 hibernate-java8 > AttributeConverter< LocalDate，java.sql.Date> 但这会产生相同的错误结果。

我该做什么，如此我的LocalDate已正确映射到数据库中的DATE？

我也尝试过使用 LocalDateTime 字段映射到一个TIMESTAMP，这工作没有问题...

解决方案

所以我得到它运行，通过添加 columnDefinition =DATE添加到 @Column 注释中。

  @Entity 
 @Table（name =my_alarms_timeline，indexes = {...}）
 public class MyAlarm {
 ... 
 @Column（name =validity_date，columnDefinition =DATE）
 @NotNull 
 private LocalDate val idityDate; 
} 
  

不知道为什么没有人看到这个问题...

I use Spring boot 1.4.2, which brings hibernate 5.0.11 (JPA 2.1). I want to use the Java 8 time classes in my entities, and so included hibernate-java8.

My entity defines a LocalDate field.

@Entity
@Table(name = "my_alarms_timeline", indexes = {...})
public class MyAlarm {
    ...
    @Column(name = "validity_date")
    @NotNull
    private LocalDate validityDate;
}

I expect this to be mapped to a DATE in my H2 database.

In my DB I declare this as validity_date DATE NOT NULL,.

When I try to run tests, I get the following error: [INFO] Caused by: org.hibernate.tool.schema.spi.SchemaManagementException: Schema-validation: wrong column type encountered in column [validity_date] in table [my_alarms_timeline]; found [date (Types#DATE)], but expecting [timestamp (Types#TIMESTAMP)]

To my surprise, if I change the DB definition to validity_date TIMESTAMP NOT NULL, I get the error

Caused by: org.hibernate.tool.schema.spi.SchemaManagementException: Schema-validation: wrong column type encountered in column [validity_date] in table [my_alarms_timeline]; found [timestamp (Types#TIMESTAMP)], but expecting [date (Types#DATE)]

This is just the reverse message of the previous one.

I also tried, instead of including hibernate-java8, to use an AttributeConverter<LocalDate, java.sql.Date> but this produces the same error result.

What must I do, so that my LocalDate is mapped correctly to a DATE in the DB?

I also tried with a LocalDateTime field mapped to a TIMESTAMP, and this works without problems...

解决方案

So I got it to run, by adding a columnDefinition="DATE" to the @Columnannotation.

@Entity
@Table(name = "my_alarms_timeline", indexes = {...})
public class MyAlarm {
    ...
    @Column(name = "validity_date", columnDefinition = "DATE")
    @NotNull
    private LocalDate validityDate;
}

Not sure why nobody else is seeing this issue...
