Question

我有一个实体，其中有一个ZonedDateTime，并带有@CreationTimestamp注释：

@CreationTimestamp
@Column(name = "created")
private ZonedDateTime created;

运行时：

mvn liquibase:diff

我收到以下错误：

[ERROR] Failed to execute goal org.liquibase:liquibase-maven-plugin:3.5.5:diff (default-cli) on project myproject: Error setting up or running Liquibase: org.hibernate.HibernateException: Unsupported property type for generator annotation @CreationTimestamp -> [Help 1]

[ERROR] For more information about the errors and possible solutions, please read the following articles:

在 pom.xml 中有我的休眠和liquibase依赖项：

<!-- The hibernate version should match the one managed by
https://mvnrepository.com/artifact/io.github.jhipster/jhipster-dependencies/${jhipster-dependencies.version} -->
<hibernate.version>5.2.12.Final</hibernate.version>

<!-- The liquibase version should match the one managed by
https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-dependencies/${spring-boot.version} -->
<liquibase.version>3.5.5</liquibase.version>
<liquibase-hibernate5.version>3.6</liquibase-hibernate5.version>

@CreationTimeStamp用于ZonedDateTime字段的正确版本是什么？

可以使用对象设置器的解决方法：

public void setDateCreated(Object object) {
        if (object.getId() == null) {
            // which will run only when the object is new
            this.dateCreated = Instant.now();
        }
    }
public void setDateUpdated() {
        // which runs everytime the object is updated
        this.dateUpdated = Instant.now();
    }

或者您可以在运行更改差异之前在liquibase更改日志上手动设置valueDate属性：

<column name="Join_date" valueDate="${now}"/>

或者在运行liquibase diff时注释掉注释，并在完成后将其重新添加。

Liquibase：diff-ZonedDateTime上生成器注释@CreationTimestamp的不受支持的属性类型
